Background: Although deleterious effects of sunlight have been increased recently, the surveillance of the attitudes toward sun-exposure and the behavioral aspect of using sunscreens in Koreans has hot been carried out. Objective: Our purpose was to evaluate the attitude toward the harmfulness of sun-exposure and behaviors of using sunscreens in Korea. Method: Five hundred and fifty-two subjects were surveyed to assess the attitude toward sun-exposure, as well as the subjects knowledge about, and the use of sunscreens. Underlying data including demographic data, skin colors, skin types, occupation, and sun-exposure, were obtained. Results: Fifty-four percent of subjects believed that sun-exposure is bad for their skins, but, on the contrary, 12.5% believed it to be beneficial. Fifty-two percent of subjects used sunscreens. Almost all subjects(93.8%) knew why to use sunscreens but 62.7% of subjects did not know the meaning of sun protective factors(SPF). Women, indoor workers, subjects less than 40 years old, with less sun-exposed, fair colored skin, or with skin type I, II, III tended to know the deleterious effects of sunlight and the meaning of SPF and used more sunscreen. Conclusion: High risk population-men, outdoor workers, subjects oider than 40 years old, with more sun-exposed, dark colored skin, or skin type VI, V could be targeted with campaigns that promote attitudinal and behavioral changes.

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.

Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.

Sun?Jin Han,Deuck Hang Lee,Jae?Yuel Oh,Seung?Ho Choi,Kang Su Kim 한국콘크리트학회 2018 International Journal of Concrete Structures and M Vol.12 No.5

In this study, prestressed hybrid wide flange (PHWF) composite girders were proposed, and full-scale flexural tests were conducted to evaluate their structural performances. This new proposed girder system was developed and designed to effectively resist external loads considering the actual construction sequences. Two specimens with and without shear connectors were fabricated and tested to examine the effect of the shear connectors for achieving the fully-composite behaviors between a cast-in-place (CIP) concrete and the prefabricated prestressed steel–concrete composite girder. The test results showed that sufficient flexural strengths and deformation capacities can be obtained in both types of PHWF composite girders with and without shear connectors. To reflect the actual construction stages of the proposed PHWF composite girder, nonlinear flexural analyses were proposed considering the prestress effect and segmental effect before and after composite with the CIP concrete, respectively. The observed and analysis results of strain behaviors of the PHWF girder specimens were also compared and discussed in detail.

Kim, Si-Hyung,Choi, In-Sun,Cho, Jin-Hwa,Park, Eun-Ju,Jang, Il-Sung,Choi, Byung-Ju,Kim, Hyun-Jung,Kim, Young-Jin,Nam, Soon-Hyeun The Korean Academy of Oral Biology 2006 International Journal of Oral Biology Vol.31 No.2

Dysplasia-associated seizure disorders are markedly resistant to pharmacological intervention. Relatively little research has been conducted studying the effects of antiepileptic drugs(AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate(MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of AEDs in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed and age-matched vehicle-injucted control animals. Field potential recordings were used to monitor amplitude and numbers population spikes, and paired pulse inhibition in response to stimulation of commissural pathway. Two commonly used AEDs were tested: diazepam 5, 2.5mg/kg;phenytoin 40, 60mg/kg. Diazepam(DZP) and phenytoin(PHT) reduced the amplitude of population spike in control and MAM-exposed rats. However, the amplitude of population spike was nearly eliminated in control rats as compared to the MAM-exposed rats. Pharmaco-resistance was tested by measuring seizure latencies in awake rats after pilocarpine administration(320mg/kg, i.p.) with and without pretreatment with AEDs. Pre-treatment with PHT 60 mg prolonged seizure latency in control rats, but not in MAM-exposed animals. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard AEDs assessed in vivo. These data suggest that animal model with cortical dysplasia can be used to screen the effects of potential AEDs.

김동욱,신선혜,김혜진,류선,이선희,장철훈,김영대,곽임수 대한감염학회 2004 감염과 화학요법 Vol.36 No.1

목적 : Vancomycin-resistant enterococci (VRE)로부터 S. aureus로의 vacomycin 내성 유전자의 전파는 오래전부터 예견되어져 왔으며 큰 걱정거리로 남아있다. 최근에 vanA 유전자를 가지고 있는 vancomycin-resistant S. aureus 2주가 미국에서 분리되었다. 이 연구의 목적은 VRE를 보균하고 있는 환자들에서 S. aureus 보균양상과 항균제 내성을 알아보는데 그 목적이 있다. 재료 및 방법 : 2001년 1월부터 2001년 12월까지 부산대학교병원에 입원하였던 환자들 중 임상검체에서 VRE가 분리된 환자 7명과 2001년 9월부터 12월까지 외과 중 환자실에 입원하였던 환자들 중 VRE 감시배양을 시행하였던 20명의 환자들을 대상으로 하였다. 환자들은 전비공, 액와부, 회음부, 직장에서 매주 면봉으로 검체를 채취하였다. 선별배지에서 검체를 배양하여 S. aureus를 분리하였고 원판 확산법을 이용하여 methicillin 감수성을 측정하였다. Broth microdilution 법으로 vancomycin MIC를 측정하였다. 결과 : 총 27명에서 73회의 방문과 292회의 배양이 시행되었으며 총 67주의 S. aureus가 분리되었다. 이중 64주(95.5%)가 methicillin 내성이었다. 전비공 MRSA 보균율은 VRE를 보균하고 있었던 환자는 19명 중 11명(58%)에서, VRE를 보균하지 않았던 환자는 8명 중 3명(37.5%)으로 VRE 보균자에서 보균율이 더 높았다. 총 64주의 MRSA의 vancomycin MIC의 분포는 0.5-2㎍/mL였으며 2㎍/mL를 초과하는 균주는 발견되지 않았다. 64주 중 vancomycin MIC가 1㎍/mL인 균주가 54주(84.4%)로 가장 많았으며 2㎍/mL 6주(9.4%), 0.5㎍/mL 4주(6.3%)의 순이었다. 결론 : VRE 환자에서 S. aureus의 보균율은 비보균자 보다 높았으며 분리된 균주들은 대부분 MRSA였다. VRSA 균주는 발견되지 않았다. Background : The transfer of vancomycin resistance from vancomycin-resistant enterococci (VRE) to Staphylococcus aureus has been predicted. The purpose of this study is to determine the prevalence and antibiotics resistance of S. aureus among patients colonized with VRE. Methods : Between January 2001 and December 2001, a prospective study was performed at Pusan National University Hospital on 27 patients. Surveillance swabs from nasal cavity, axilla, perineum, and rectum were obtained at weekly intervals. Methicillin susceptability of S. aureus was determined by oxacillin disk diffusion test and minimum inhibitory concentration (MIC) for vancomycin by microdilution broth test. Results : Total of 292 swab cultures were performed and 67 S. aureus isolates were collected. 64 isolates (95.5%) were resistant to methicillin. The prevalence of nasal MRSA carrier in 19 patients colonized with VRE was higher than that in 8 patients not colonized with VRE (58% vs. 37.5%). In 64 MRSA isolates, MIC (㎍/mL) for vancomycin ranged from 0.5 to 2. No isolates with MIC >2 ㎍/mL were observed. MIC of 1 ㎍/mL was shown (observed) in 54 isolates, 2 ㎍/mL in 6 isolates, and 0.5 ㎍/mL in 4 isolates. Conclusion : The prevalence of S. aureus with colonization of VRE is higher than that without colonization of VRE. Most of S. aureus isolates were resistant to methicillin. VRSA isolates were not observed.

김동인,이진욱,김임,이선미,은헌정 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.4

국문초록본 연구는 중년기 우울증 여성의 생활사건 스트레스, 대처 방식, 사회적 지지, 가족 관계 등의 정신사회적 요인들을 알아보기 위한 것으로 각 변인들이 어떻게 우울과 관계가 있는지를 우울증 환자 집단과 정상인 집단으로 나누어서 비교 연구하였다. 이를 위해 35세 이상 64세 이하의 116명의 우울증 환자와 113명의 정상인을 대상으로 Beck 우울 질문지(BDI), 생활사건 질문지, 대처방식 척도, 대인관계 지지 평가척도(ISEL), 가정환경척도 등의 검사를 하였고 다음과 같은 결과를 얻었다. 1) 최고 스트레스는 환자 집단의 경우 결혼생활 스트레스(42명, 36.2%), 정상인 집단의 경우는 가정생활 스트레스(44명, 38.9%)였다. 2) 소극적 대처(t=0.93, p=.35)만을 제외하고 환자 집단과 정상인 집단에서 BDI 우울 점수(t=15.94, p<.0001), 생활사건 스트레스 점수(t=4.73, p<.0001), 적극적 대처점수(t=6.29, p<.0001), 사회적 지지점수(t=7.20, p<.0001), 가족 관계 점수(t=5.75, p<.0001)에서 유의한 차이를 보였다. 3) 우울증 환자 집단에서 BDI 우울 점수는 생활사건 스트레스(r=.24, p<.01) 변인과 유의한 정적 상관을 보였고, 적극적 대처(r= -.22, p<.01) 변인, 사회적 지지(r= -.35, p<.001) 변인, 가족관계(r= -.30, p<.001) 변인과는 유의한 역 상관을 보였다. 4) 우울증 환자 집단에서 BDI 우울에 대한 각 변인들의 중다회귀분석은 사회적 지지(12.3%, β= -.281, T= -3.162, P=.002, 생활사건 스트레스(5.1%, β=.279, T=3.195, P=.002), 적극적 대처(3.5%, β= -.204, T= -2.225, P=.028) 변인이 합하여 20.9%의 설명력을 나타냈다. 5) 중년기 여성에서 생활사건 스트레스는 가족 관계에서 겪는 스트레스가 가장 큰 스트레스였고, 대처방식은 우울과의 관계에서 일관성이 부족하였으며, 사회적 지지는 우울에 영향을 주는 가장 중요한 요인이었고, 가족관계는 양 집단에서 유의한 차이는 있었으나 우울에 대하여 의미있게 설명하지 못하고 있다. ABSTRACTLife Events, Coping Styles, Social Support, and Family Relationships of Middle-Aged Depressed Women Jin-Wook Lee, M.D., Yim Kim, M.D., Sun-Mi Yi, M.S., Dong-In Kim, M.D., Heon-Jeong Eun, M.D. Department of Neuropsychiatry, Presbyterian Medical Center, Chonju The objective of this study was to explore the psychosocial factors such as life events, coping styles and family relationships in middle-aged depressed women. This study was designed to compare how different variables relate to depression in two different test groups : a depressed patient group and a normal group. The Beck Depression Inventory(BDI), The Ways of Coping Checklist, Interpersonal Support Evaluation List(ISEL), Family Environment Scale were administered to 116 depressed patients and 113 normal persons between the ages of 35 and 64. The results were as follows : 1) The highest stress was marital stress(n=42, 36.2%) in patient group and family stress(n=44, 38.9%) in normal group, respectively. 2) There were significant differences between patient group and normal group in BDI scores(t=15.94, p<.0001), life events(t=4.73, p<.0001), active copinig(t=6.29, p<.0001), social support(t=7.20, p<.0001), and family relationships(t=5.75, p<.0001) except for passive coping(t=0.93, p=.35). 3) In depressed patient group, BDI scores had a significantly positive correlation with the scores of the life events(r=.24, p<.01) and negative correlation with active coping(r= -.22, p<.01), social support(r= -.35, p<.001) and family relationships(r= -.30, p<.001). 4) In depressed patient group, multiple regression analysis showed that social support(12.3%, β= -.281, T= -3.162, P=.002), life events(5.1%, β=.279. T=3.195, P=.002), and active coping(3.5%, β= -.204, T= -2.225, P=.028) had predictability on the BDI scores and the total predictability was 20.9%. 5) Stress experienced in family relationships were highest in life events and there was a lack of consistency(in the BDI scores of the coping styles). Social support was the most important factor and there were no significant differences between the two groups in family relationships.
