The central government plays an important role and function in disaster management in order to mitigate personal and property damages from disasters. This study analyzed the process of organizational change undergone by the disaster management units of the Korean government since 1948 right after liberation. Temporal categorization of organizational changes was based on the hierarchical change of the organization in charge of disaster management tasks. We collected the data on the changes in disaster management organization in Korea from published reports, laws, and organizational records. We analyzed all kinds of organizational units related to disaster management to deduct the characteristics of organizational changes in each period and compared them based on the principles of division and coordination. Based on the results of analysis, we derived implications for the organizational structure and reform of disaster management organizations in Korea.

The private sector can play a crucial role in enhancing disaster resilience. The industry classification and statistics can provide the basic information needed to understand the landscape of the disaster and safety industry (DSI 1 ). The purpose of this study is to investigate problems in the first supply-based DSI classification (DSIC 2 ) of Korea and suggest a more appropriate demand-based system. A correlation analysis and network cluster analysis were conducted to demonstrate problems of the first DSIC in Korea. The new DSIC was then proposed from a hazard and function-based approach. The effectiveness of the new DSIC from the viewpoints of exhaustiveness and mutual exclusiveness was validated using the Global Clustering Coefficient. The new DSIC is more effective in reducing overlapping industrial activities in industrial divisions. The new DSIC proposed in this study was adopted by the Statistics in Korea in 2018 and is being used as the official DSIC in Korea.

PROBLEM Inflammation is a key process in the establishment and progression of endometriosis. Resistin, an adipocytokine, has biological properties linked to immunologic functions, but its role in endometriosis is unclear. METHOD OF STUDY Resistin gene expression was examined in eutopic and ectopic endometrial tissues from women with (n=25) or without (n=25) endometriosis. Resistin mRNA and protein levels were determined in endometrial tissue using quantitative real-time reverse transcription PCR and Western blotting, following adipokine profiling arrays. RESULTS Resistin protein was detected in human endometrial tissues using an adipokine array test. Resistin mRNA and protein levels were significantly higher in ectopic endometrial tissue of patients with endometriosis than in normal eutopic endometrial tissue. CONCLUSION Our results indicate that resistin is differentially expressed in endometrial tissues from women with endometriosis and imply a role for resistin in endometriosis-associated pelvic inflammation.

Concerns for negative effects of oral contraceptives (OCs) on bone mineral density (BMD) in long-term users have been raised, since OCs suppress the hypothalamic-pituitary-ovarian axis. However, there have been still limited data regarding the effects of long-term OC use on BMD in young women in the twenties. We investigated the effects of long-term OC use for the prevention of endometrioma recurrence on BMD in young women. Ninety-two women aged 20-30 years who underwent conservative surgery for endometrioma and used postoperative OC for at least 12 months to prevent the recurrence were included for this cross-sectional study, and BMDs after OC use were analyzed. The mean age at starting OC and duration of OC use was 25.6 ± 2.9 years and 40.7 ± 28.5 months, respectively. No correlation was found between BMDs and age at starting OC at all sites. In addition, BMDs were also not correlated with the duration of OC use, and were comparable according to the dose of OC (20 versus 30 μg). In conclusion, long-term use of OCs has no adverse effect on BMD in post-adolescent young women.

Autophagy appears to play an important role in the normal development and maintenance of homeostasis in a variety of tissues, including the female reproductive tract. However, the role of autophagy and the association between autophagy and apoptosis in cyclic remodeling of the human endometrium have not been described. Therefore, we investigated the involvement of autophagy during the human endometrial cycle and its association with apoptosis. Endometrial samples were obtained from 15 premenopausal, nonpregnant women who underwent hysterectomies for benign gynecological reasons. The autophagy-associated protein, microtubule-associated protein 1 light chain 3 alpha (MAP1LC3A), was immunolocalized, and its expression level was measured by Western blot analysis. Apoptosis was evaluated by measuring the expression level of cleaved caspase 3 protein. MAP1LC3A protein was primarily expressed within the endometrial glandular cells and increased during the secretory phase. The expression level of the membrane-bound form of MAP1LC3A (MAP1LC3A-II) also increased as the menstrual cycle progressed, reaching a maximum level during the late secretory phase. This pattern coincided with the expression of cleaved caspase 3. Furthermore, expression of MAP1LC3A-II and cleaved caspase 3 increased in the in vitro-cultured endometrial cancer cells when estrogen and/or progesterone were withdrawn from the culture media to mimic physiological hormonal changes. These findings suggest that endometrial cell autophagy is directly involved in the cyclic remodeling of the human endometrium and is correlated with apoptosis. In addition, we inhibited autophagic processes using 3-methyladenine (3-MA) or bafilomycin A1 (Baf A1) to evaluate the role of autophagy in apoptosis induction in endometrial cancer cells. While the inhibition of autophagosome formation using 3-MA did not decrease apoptosis or cell death, the inhibition of autophagosome degradation by fusion with lysosomes using Baf A1 increased apoptosis and cell death, suggesting that the accumulation of autophagosomes induces apoptosis. Furthermore, Baf A1-induced apoptotic cell death was decreased by the apoptosis inhibitor N-benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone (Z-VAD-FMK). In conclusion, these results indicate that autophagy is involved in the endometrial cell cycle affecting apoptosis and is most prominent during the late secretory phase.

Objectives: To evaluate the effects of transdermal estrogen therapy on bone mineral density (BMD) in postmenopausal Korean women. Methods: A total of 149 healthy postmenopausal women were retrospectively evaluated: 100 were on hormone therapy (HT) and 49 were the control group. For the HT group, 54 applied estrogen transdermally using either a patch (n = 21) or gel (n = 33), and 46 took estrogen orally (conjugated estrogen 0.625 mg or equivalent). Demographic profiles and changes in BMD over two years were compared according to the route of the estrogen. Results: No differences were found in age, age at menopause, parity, body mass index, and type of menopause among the oral, transdermal and control groups. Compared with controls, HT significantly increased BMD after 2 years in both the lumbar spine and the total hip. The increases in BMD at both lumbar spine and hip were comparable between the oral and transdermal groups. There were also no differences in BMD changes according to progestogen addition in either the oral or transdermal groups. Conclusion: Transdermal estrogen therapy increases BMD, comparable to oral estrogen, in postmenopausal Korean women. (J Menopausal Med 2014;20:111-117)

Objective The aim of this study was to evaluate the prevalence of hyperprolactinemia in adolescents and young women with menstrual problems. Study Design This study included 1704 young women with menstruation-related problems. The patients were classified into group I (age, 11-20 years) or group II (age, 21-30 years); the prevalence of hyperprolactinemia was analyzed according to age and categories of menstruation-related problems. Results For primary amenorrhea and oligomenorrhea, the prevalence of hyperprolactinemia was low in both groups. However, hyperprolactinemia was a relatively common cause of secondary amenorrhea (5.5% for group I and 13.8% for group II, respectively); it was more frequent in group II ( P = .001); the prevalence of prolactinoma was also higher in group II ( P = .015). For abnormal uterine bleeding, hyperprolactinemia was more common in group II (2.6% for group I and 9.4% for group II; P Conclusion Hyperprolactinemia is not rare in young women with menstruation-related problems; its prevalence varies according to age and manifestations.

Achalasia is a rare motor disorder that is frequently associated with poor fetal outcomes and serious maternal complications due to severe malnutrition. Symptoms of achalasia include dysphagia, regurgitation, weight loss, nausea and vomiting. These symptoms may be mistaken for hyperemesis gravidarum in early pregnancy. We report a case of a 37-year-old pregnant woman who was treated conservatively as hyperemesis gravidarum at first, but later was diagnosed as achalasia with persistent symptoms and was treated by pneumatic dilatation. If symptoms of emesis persist after the first half of pregnancy, clinicians should suspect a possibility of achalasia. Pneumatic dilatation is currently the main treatment for achalasia in pregnancy because of its lower risk, lower cost and good efficacy.

Objective: Total laparoscopic hysterectomy (TLH) is becoming more commonly used as an alternative to traditional abdominal hysterectomy and Analyzing the turning point of a learning curve can be useful in planning training programs. This study was to define the average turning point of a learning curve of TLH by comparing three separate gynecologists in one institute. Methods: Retrospective analysis of the first 140 consecutive cases of TLH performed by three separate gynecologists A, B, and C. Patients of each gynecologist were divided into 7 equal groups of 20 operations classed chronologically. Patient’s age, uterus weight, operation time and pre-post operative hemoglobin difference of the three gynecologists were compared. Operation time and pre-post operative hemoglobin difference were evaluated to build learning curves for each gynecologist. Results: Learning curve built by operation time showed turning point after 80~100 cases in all three gynecologists. Learning curve built by pre-post operative hemoglobin difference did not show a decreasing pattern. There were no statistical differences in patient’s age and pre-post operative hemoglobin difference between the three gynecologists. However, mean uterine weight of gynecologist C was significantly lighter than that of gynecologist A and B. Operation time was significantly longer in cases by gynecologist C than in cases by A and B. Conclusion: At least 80~100 cases of experience in TLH is needed for a gynecologist to reach the turning point of the learning curve. This result can be used as a guide to the training program of TLH.

목적: 산후출혈로 동맥색전술을 시행한 환자들을 분석하여 동맥색전술의 실패의 원인과 관련된 인자들에 대하여 알아보고자 하였다. 연구 방법: 2004년부터 2008년까지 고려대학교 의료원에서 산후출혈로 동맥색전술을 시행한 60명의 환자의 진료 기록과 동맥 조영술 결과를 후향적으로 분석하여 성공군과 실패군을 비교하였다. 결과: 동맥색전술의 전체 성공률은 88.3% (53/60명)였고 실패한 경우는 11.7% (7/60명)였다. 색전술의 실패는 비정상태반인 경우 통계적으로 유의하게 높았으며 (P=0.034), 특히 태반 유착이 동반된 전치태반의 경우에서 더욱 그러하였다 (P=0.009). 각 대상군의 나이, 분만력, 분만 방법, 출혈시기, 전원 여부, 시술 전 수술 여부, 시술 시 활력징후, 시술 전 혈색소 수치, 분만 후 색전술까지 시간, 중환자실 치료 여부 등은 차이가 없었다. 결론: 산후출혈 환자에서 동맥색전술은 성공률이 높고 합병증이 적은 안전한 시술 방법이나 출혈의 원인이 비정상태반인 경우 동맥색전술이 실패할 가능성이 높다.

We experienced a case of adult T cell leukemia/lymphoma (ATLL) in a 48-year-old Korean female, who has never been abroad since birth and no history of blood transfusion. The patient had hypercalcemia and multiple lymphadenopathy. Histopathologic study of left cervical lymph node (LN) and bone marrow (BM) revealed that infiltrates of malignant lymphoid cells were composed of small, medium and large cells with pleomorphic nuclei. Smears of peripheral blood (PB) showed lymphopenia (16%) with the appearance of a few atypical lymphoid cells (less than 2%), but not the typical clover leaf cells seen in ATLL. Immunophenotypic study of LN and BM revealed T cell phenotype. PB showed increased CD4+ T cell (T(H), CD3/CD4+, 57%) and decreased CD8+ T cell counts (T(S), CD3/CD8+, 6.7%). The sera of the patient and her family were reactive for HTLV-I antibody. The specific sequences of pol, env, and tax of HTLV-I DNA were detected in the lymphoma cells and peripheral blood mononuclear cells (PBMC) using polymerase chain reaction. Ultrastructural examination of PBMC confirmed numerous type c virus particles in extracellular space. This case was an acute type of ATLL without overt leukemic features in PB. Despite chemotherapy and intensive conservative treatment, she died 3 months after admission.
