The health-promoting qualities of ultraviolet light have been well recognized, but it also induces deleterious effects from sunburn to skin cancer, Since our enviroment exposes us to both ultraviolet and infrared rays at the same time, the latter is considered to influence to some extent the cutaneous effects of the former. In recent years, it has become increasingly apparent that the biologic effects of one type of radiation may be modified by wavelengths of different energies. Interactions of this kind are complex and occasionally result in true synergy or antagonism. Although there are several reports on these interactions, the results are not in accordance. This study was undertaken to investigate the influence of infrared radiation (IR) on ultraviolet radiation (UVR)-induced skin injury, especially minimal erythema dose (MED). Thirty-five healthy medical students participated in this study between May and June, 1983. One side of the back was exposed to IR with UVR while as a control the other side was exposed only to VVR. The results were summarized as follows : 1. In one experiment treated with IR before UVR, the mean MED-S.D. of the treated site was 17 7+5 3 (sec) and that of the control site was 18. 3-+6. 4 (sec)- The increase of the MED was statistically significant. (p<0. 01], paired t-test) Among the fifteen subjects, the MED was increased in 73% (11/15), and the same in 27% (4/15).

PURPOSE: This study was conducted to investigate factors affecting the job embeddedness of workers in the manufacturing industry. METHODS: The survey was conducted on 261 workers of the manufacturing industry in P city and Y city with the help of a structured self-report questionnaire, administered between June 10 and June 30, 2017. Data were analyzed using descriptive statistics, a t-test, ANOVA, a Scheffés test, Pearson's correlation coefficients, and stepwise multiple regression. RESULTS: There were significant differences in job embeddedness according to educational level, marital status, jobs and types of employment, satisfaction with salary, stress level, and the perceived health status of the subjects. There were significant positive correlations between role clarity of job demands (r=.45), leader member exchange (r=.48), recovery experience from job stress (r=.27), and job embeddedness. From the multiple regression analysis, the most significant factors affecting job embeddedness were found to be leader member exchange (β=.43), recovery experience from job stress (β=.22), and job demand (β=.15). These variables explained 35.0% of the total variance in job embeddedness. CONCLUSION: In order to increase job embeddedness of workers in the manufacturing industry, it is necessary to prepare measures to increase job demand, leader member exchange, and recovery experience from job stress.

Purpose: This study aimed to investigate the factors affecting cardiovascular disease in middle-aged male workers. Methods: The participants were 137 male office workers over 40 years old and under 60 years old working in small- and medium-sized workplaces from three southern provinces of Korea. Data were collected through self-reported questionnaires and health screening reports from the 2014 National Health Examination. The influencing factors included general characteristics of participants, anger expression style, and occupational stress. Data were analyzed using t-test, ANOVA, and regression analysis with SPSS 22.0. Results: The mean score of risk of cardiovascular disease was 6.73±4.69 and there were significant differences in exercise (t=2.13, p=.035) working time (t=-2.15, p=.034). Logistic regression analysis showed that, when adjusted for exercise and working time, the probability of becoming under a cardiovascular disease risk was 21% higher for those who anger-in (OR=1.21, 95% CI=1.02~1.44, p=.027) and 12% higher for those perceived occupational stress (OR= 1.12, 95% CI=1.01~1.24, p=.030). Conclusion The results suggest developing the strategies for middle-aged male workers to encourage exercise and to decrease occupational stress, as well as an appropriate anger expression style to improve holistic aspect of health considering their demographic characteristics.

We reviewed the 43 medical records of patients with cellulitis or erysipelas who had been admitted at the depar1ment of dermatology of Seoul National University Hospital and followed them up for mean 21.6 months. The results were as follows. 1. The sex ratio of patients with cellulitis was 1:1.4 and the average age was 49 years. 2. The lower extremity as the most frequently invloved site of cellulitis with the frequency of 58.1% (25 cases), with the head and neck being involved in 16 cases(37.2%) and trunk and upper extremity in 1 case each(2.3% ). 3. The portals of infecticin were suspected in 33 cases(76% ), where tinea pedis was detect,ed in 18 cases(41.9%), previous skin infeection 10 cases(23.3%) and trauma in 9 cases(20.9%). 4. Initial systemic symptoms were fever(76.7%), chill(65.1%) and headache(37.2%). Erythema(100%), local heating(90,7%), tenderness(88.4%), swelling(86.0%), ulcer(16.3%), bulla(14.0%), lymphangitis(9.2%) and lymphadenit,is(9.2%) were found in the skin lesions. 5. The laboratory findings revealed leukocytosis in 35.7%, elevaed ESR in 86.8% positive 6. ASO titer in 63.0% and positive CRP in 80%, Microorganism. were detected in only 1 of 15 blood cultures, in 2 of 4 bulla fluid cultures and in 7 of 9 bus cultures. There was no growth of causative microorganisms in 3 tissue cultures and 9 saline needle aspiration cultures. Penicillin was used as primary antibiotics in 19 cases, which changed to another antibiotics due to lack of improvement in 3 cases and cefazolin was used in 21 cases, which changed in 2 cases due to the same reason. 7. Average admission priod was 11 days(range from 3 to 20 days) and 30.2% of patients wit.h cellulitis experienced recurrence, but 48% on low extrernity in contrast with 6.7% on head and neck.

Lymphomatoid papulosis is a disease; clinically benign, histologically malignant. Clinically, it may sirnulate pityriasis lichenoides et varioliformis acuta, but histologically it suggest malignant lympboma due to the presence of polymorphous lymphoid infiltrate consisting of sma11 lymphocytes intermingled with conspicuous large atypical cells. Recently, many autbors consider lymphornatoid papulcsis as a Cutaneous T-cell lymphoma, and malignancy has been reported to develop in some patients. We experienced a case of lyrnphomatoid papulosis in 26-year-old woman and treated with PUVA successfully. PUVA treatment may be proven useful in controlling this disease and it rnay also inhibit the development of malignancy.

OBJECTIVE: The purpose of this study was to analyze the clinical characteristics and prognosis of small cell uterine cervical carcinoma with neuroendocrine differentiation. METHODS: Patient's medical records were reviewed retrospectively who were diagnosed as small cell carcinoma of uterine cervix and were treated at Hanyang University Hospital between 1972 and 1997. RESULTS: Between 1972 and 1997, of 1164 patients who were diagnosed as invasive cervical cancer, there were 10 cases of small cell carcinoma of uterine cervix in the department of obstetrics and gynecology, Hanyang University Hospital. The incidence of small cell carcinoma in invasive cervical cancer was 0.9% (10/1164). Of 10 small cell carcinoma, seven(70%) were neuroendocrine types which were identified with several kinds of immunohistochemical stains (Chromogranin, Grimelius, and/or NSE). The age of these 7 patients ranged from 34 to 63 years (mean 49). Two were in stage Ib, 3 in stage lla, I in stage IIIb, and 1 in stage IVb. Patients with stage Ib-IIb (n 5) received 3-5 courses of neoadjuvant VBP chemotherapy (vinblastine, bleomycin and cis-platinum) followed by radical hysterectomy with pelvic and paraaortic node dissection. One IIIb patient was managed with concurrent chemo-radiation(3 cycles of cis-platinum & 5-FU) followed by 6 courses of chemotherapy. One IVb patient was treated by palliative chemotherapy with 8 cycles of VBP chemotherapy. Of 5 paticn(s who underwent surgery, none showed pelvic lymph node metastases. These 7 patients were folk>wed for 8 - 62 months (average: 20 months). During this period, 5 patients died of disease hetween 8 and 62 months later and 2 patients are still alive for 12 (stage Ib) and 26 months (stage Ib), respectively. In the contrary, of 3 patients without neuroendocrine differentiation, who underwent neoadjuvant VBP chemotherapy followed by radical hysterctomy with pelvic and paraaortic node dissetion or concurrent chemo-radiation, two stage IIb patients are still alive for 58 and 74 months, and one IIIb patient died of disease 12 months later. CONCLUSION: In summary, neuroendocrine differentiation seemed to adversely affect the prognosis and longterm survival of small cell carcinoma of uterine cervix. So, for this high risk group, more aggressive therapy would be need to improve outcome. However, as the number of patients were small in our study, further study with large number of patients are warranted.

PURPOSE: This study was to investigate factors that influence health examination for unmarried women. METHODS: A correlation study was carried out with 144 unmarried women with an age range of 35~49 years through self-administered questionnaires. This questionnaire included Health Belief Model modifying factors (demographic . sociological, structural, and cues to action variables). Data were analyzed using descriptive statistics, chi2-test, multiple logistic regression. RESULTS: The mean age of participants was 37.2+/-2.67 years. Rates for breast cancer, cervical cancer and comprehensive health examination were each 34.7%, 38.2% and 94%. In multiple logistic regression analysis, influencing factors on physical examination were age(OR=0.06, 95% CI: 0.02~0.26), personal medical insurance (OR=6.30, 95% CI: 1.60~24.82), housemate (OR=7.63, 95% CI: 2.58~22.52), exercise (OR=3.72, 95% CI: 1.37~10.12) in breast cancer examination, and age (OR=0.08, 95% CI: 0.02~0.34; OR=0.07, 95% CI: 0.01~0.85), personal medical insurance (OR=14.17, 95% CI: 2.94~68.23), sexual experiences (OR=3.38, 95% CI: 1.28~8.91), drinking (OR=2.92, 95% CI: 1.14~7.49) in cervical cancer examination. CONCLUSION: The results emphasize the necessity of preparing nursing education and intervention in consideration of associated factors which influence on the health examination in unmarried women.
