Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Purpose: The purpose of this study was to investigate the relationships between the degree of smart phone addiction among adolescents and their depression and anxiety levels. Method: In this study, 379 high school students were selected using the convenient sampling method. The instruments used for this study were smart phone addiction measure, the CES-D (Center for Epidemiological Studies-Depression Scale), and the STAI (State-Trait Anxiety Inventory). Data were analyzed using the SPSS 20.0 program with descriptive statistics, t-test, ANOVA with Scheffe test, and Pearson’s correlation coefficient. Result: The mean score for smart phone addiction was 40.45±17.27, depression was 36.56±9.58, state anxiety was 44.00±9.61, and trait anxiety was 45.70±9.75. There were significant differences between the degree of smart phone addiction and the following variables: gender (t=-4.953, p<.001), hours of smart phone use per day (F=12.259, p<.001), types of frequently used features (F=3.485, p=.008), and satisfaction level for smart phone (F=5.18, p<.001). There were statistically significant relationships (p<.001) among degree of smart phone addiction, depression level, and state and trait anxiety levels. Conclusion: The results of this study suggested that there was a significant relationship between smart phone addiction and mental health, specifically, depression and anxiety among adolescents. Further research is needed to develop nursing strategies to provide care for adolescents who frequently utilize smart phones.

The incidence of hematologic disorders in patients with Down's syndrome is significantly increased, about 14∼30 - fold higher than in general population and includes neonatal transient abnormal myelopoieis and acute leukemias. The age of onset of leukemia in Down's syndrome is peaking first in the newborn period and then under 4 years of age. Down's syndrome with acute leukemia above the age of 20 is very rare and it's treatment oucome is unclear. The treatment of Down's syndrome with leukemia has been controversial because of toxicity and associated congenital cardiac and other abnormalities. But if treated adequately, children with Down's syndrome show a favorable response to anti-leukemia therapy. A 24-year-old man with Down's syndrome was first seen for the evaluation of anemia and thrombocytopenia. The peripheral blood morphology and bone marrow study revealed acute myelogenous leukemia, cytogenetic study of bone marrow showed trisomy 21. Beacuse of his sicioeconomic condition and medical abnormalities including deafness, visual loss, he was treated with low dose subcutaneous cytosine arabinoside(Ara-C) for 11 days. Complete remission was obtained after 37 days. The complete remission lasted for 5 months. He subsequently relapsed, and died 6 months later.

김수동,김신우,김정국,하승우,김보완 慶北大學校 醫科大學 1993 慶北醫大誌 Vol.34 No.4

시상하부-뇌하수체질환의 기저질환에 따른 종합적 뇌하수체전엽 자극검사의 진단적 가치를 알아보고자 81례의 뇌하수체 기능부전증환자를 대상으로 시상하부질환군과 Sheehan증후군, 말단비대증과 프로랙틴종, 그리고 뇌하수체선종에서 시야장애가 동반된 군과 장애가 없는 군으로 나누고 기능검사의 결과를 비교하였다. 1. Sheehan증후군 15례 가운데 GH 및 cortisol결핍이 전례(각각 100%)에서 FSH, LH 및 TSH결핍이 11∼12례(73∼80%)에서 관찰되었고 13례(86%)에서는 TRH에 대한 PRL분비증가가 저하 또는 소실되었다. 두개인두종 10례를 포함한 시상하부질환 14례 가운데 12례(86%)는 PRL의 기저지가 비정상직으로 증가되어 있었으며 TRH자극에 대해 PRL분비 증가가 11례(79%)에서 둔화되어 있었다. GH분비능도 11례(79%)에서 저하되었으며 그 밖의 cortisol, LH, TSH, FSH의 순으로 분비능이 저하되어 있었으나 그 빈도는 Sheehan증후군에 비해 전반적으로 낮았다. 2. 말단비대증 18례 가운데 14례(78%)에서 GH기저치가 비정상적으로 증가되어 있었고 13례(72%)는 저혈당자극에 대해 정상적인 GH의 증가를 보였으며 8례(44%)에서 고프로랙틴 혈증이 동반되었다. 프로랙틴종 18례 가운데 전례(100%)에서 PRL기저치가 증가되었고 13례(72%)에서 TRH에 대한 PRL의 증가반응이 둔화되었다. LH, FSH, cortisol 및 TSH분비능의 장애는 말단비대증군에서 프로랙틴종에 비해 다소 높은 빈도를 보이는 경향이었다. 3. 뇌하수체선종 가운데 시야장애가 동반된 21례에서 시야장애가 없는 23례에 비해 GH, cortisol및 LH의 분비반응이 저하된 빈도가 다소 높은 경향이었다. 이상의 결과로 보아 종합적 뇌하수체전엽 기능검사는 시상하부-뇌하수체질환의 기저질환을 진단하는데 중요한 정보를 제공할 수 있다고 생각한다. The combined stimulation test using TRH, LHRH and insulin has allowed investigation of the reserve of all pituitary tropic hormones under physiological and pathological conditions. To evaluate the diagnostic efficacy of this test for differentiating the underlying causes of hypopituitarism, we analyzed retrospectively the results of these tests done in 81 patients with proven hypothalamo-pituitary disorders. 1. In 15 patients with Sheehan's syndrome as a typical type of primary hypopituitarism, responses of both GH and cortisol to insulin-induced hypoglycemia were decreased in 15 cases all (100% in both) and of FSH, LH and TSH in 11 to 12 cases(73-80%). Incremental response of prolactin(PRL) to TRH was diminished or absent in 13 cases(86%). In 14 patients with hypothalamic diseases, including 10 cases of craniopharyn-gioma, as a representative secondary hypopituitarism, the basal PRL levels were abnormally elevated in 12 cases (86%) and both responses of PRL to TRH and of GH to hypoglycemia were blunted in 11 cases (79% in both). The frequency of impaired cortisol secretion was 50%, followed by LH, TSH and FSH secretion : overall frequency much lower than in Sheehan's syndrome. 2. In 18 acromegalics with pituitary adenoma, basal GH levels were abnormally elevated in 14 cases(78%) and incremental responses of GH to hypoglycemia were found in 13(72%). Hyperprolactinemia was accompanied in 8 (44%). In 18 patients with prolactinoma, basal PRL levels were moderately to markedly elevated in all of them(100%) and responses of PRL to TRH were blunted in 13(72%). The frequency of impaired secretion of LH, FSH, cortisol and TSH was slightly higher in acromegalics than in patients with prolactinoma. 3. The frequency of impaired secretion of GH, cortisol and LH tended to be slightly higher in patients with pituitary adenoma associated with visual field defect than those without visual field defect. These results suggest that the combined pituitary stimulation test will give us some of reliable information for evaluating the underlying causes of hypopituitarism.

Method for Protection of Single‑Line‑Ground Fault of Distribution System with DG Using Distance Relay and Directional Relay

Jung‑Hun Lee,Min‑Su Park,Hong‑Seon Ahn,Kyung‑Won Park,Jun‑Seok Oh,Seung‑Gyu Jeon,Dong‑Kyu Kim,Jae‑Eon Kim 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.4

When large scales DG are connected to the distribution system of unidirectional power currents, bi-directional power currents are formed, making it impossible to use conventional overcurrent protection methods alone to detect and isolate fault sections for ground and short-circuit faults. To solve these problems, this study proposed the method of protection against single-line-ground fault of common neutral line multi-contact local power distribution system using distance relay and directional relay. The proposed protection method was applied to the common neutral multi-ground distribution system to validate the protection against single-line-ground fault through the PSCAD/EMTDC software package and efectively detect and isolate only the zone of single-line-ground fault without malfunctions.
