Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is a disorder characterized by the repetitive collapse of the pharyngeal airway during sleep, which leads to oxygen desaturation, sleep fragmentation, daytime sleepiness, and increased risk for hypertension and stroke. We investigated the clinical factors related to the severity of OSAHS. Polysomnography was performed in three hundred and ninety five consecutive adult patients with clinical symptoms of obstructive sleep apnea syndrome. All patients completed the sleep questionnaire and the Epworth Sleepiness Scale before polysomnography. Patients were classified into four groups based on the severity of their polysomnographic data: Non-OSA group, characterized by Apnea-Hypopnea Index (AHI) < 5; mild OSA group, by AHI 5-15; moderate OSA group, by AHI 16-30; and severe OSA group, by AHI > 30. Neck circumference was also measured at the cricothyroid level. A total of 395 patients (336 men and 59 women) were studied. In the non-OSA group, there were 55 patients; their mean neck circumference was $39.63{\pm}4.24cm$ and mean BMI was $24.48{\pm}3.53$. In the mild group, there were 101 patients; their mean neck circumference was $41.93{\pm}3.75cm$ and mean BMI was $25.33{\pm}2.94$. In the moderated group, there were 93 patients; their mean neck circumference was $43.27{\pm}3.50cm$ and BMI was $25.90{\pm}2.88$. In the severe group, there were 146 patients; their mean neck circumference was $44.94{\pm}3.93cm$ and mean BMI was $26.81{\pm}3.76$. Men had significantly larger neck circumference than women ($Mean{\pm}SD$, $43.72{\pm}3.83$ vs $39.17{\pm}4.30$, p < 0.001), and higher AHI than women ($29.12{\pm}22.65$ vs $14.63{\pm}14.11$, p < 0.001). Multiple regression analysis revealed that neck circumference was the most significant predictor of AHI. Neck circumference and BMI were positively correlated with the severity of OSAHS. The severity of OSAHS was greater in men than in women.

Authors studied on the prevalence of 94 cases of pneumoconiosis who were found out through the screening test on 1,062 workers engaged in welding process at 36 shipyard in Pusan area from March 1st, 1986 to November 30th, 1986. The result were as follows; 1. Dust concentration was measured $4.49{\pm}0.54mg/m^3$ in the small scale shipyard while it was $6.25{\pm}1.08mg/m^3$ in the large one. 2. The prevalence of welder's lung was 8.9% (male:8.5%, female:12.0%) and this is consist of 4.9% suspected pneumoconiosis and 4.0% pneumoconiosis more than category 1/0. 3. The prevalence was significantly increased according to the duration of dust exposure(p<0.05), and it showed the increasing tendency by the age group. 4. The prevalence was significantly higher in the large scale shipyard than is the small scale one(p<0.01). 5. The type and shape of opacities were 71.4% of p type and 28.6% of q type, however no pneumoconiosis with r type observed in this study. 6. The main subjective symptoms were the sputum(29.8%), coughing(25.5%), shortness of breath(20.2%), fatique(6.4%), and chest pain(5.3%). In other hand, 57.4% of pneumoconiosis were asymptomatic. 7. The prevalence of pulmonary tuberculosis was radiologically 1.7% in all subjects including 5.3% in pneumoconiosis and 1.3% in no pneumoconiosis(p<0.01).

Though people occupationally exposed to machineries and automation in the industrialized society desire work involving decreased strength, due to the continuous and repetitive activities, a new industrial stress is present. Studies on prevalence of musculoskeletal disease and their related risk factors have evolved. In this study in relation to work tasks, we investigated the differences in musculoskeletal symptoms occurring In each body region. The results of the survey were as follows. 1. When comparing age, level of education, work duration, job satisfaction and leisure time activities according to work task, age in control group was $38.83{\pm}5.5$, in comparison to the other 2 groups was smaller(p<0.05), and level of education in control group was higher (p<0.05). Work duration in the cutting department was $8.04{\pm}4.99$ years longer than the other 2 groups (p<0.05), but there was no difference in the job satisfaction and leisure time activities. 2. The mean of symptom scores of each work task was 1.54 in the cutting department, 1.57 in the press department and 1.59 in the control group, and there was no significant differnce in the 3 groups. The mean of symptom scores for upper extremities in the control group was low but no statistically significant diffrence was shown. 3. When comparing the mean of symptom score according to work task in the each body region, in the shoulder region, the symptom score in the press department which desired strength was higher than the other 2 groups but no significant difference was shown. In the wrist region the cutting department scored 1.01 and in comparison to the other 2 groups was significantly increased (p<0.05). 4. The results of the univariate regression analysis on the major individual risk factors associated with musculoskeletal symptom relating work showed that previous symptom complaints in the same body region was significant risk factor(p<0.001) in the whole body Besides wrist, hip, and knee, psychological problem was shown to be a significant factor(p<0.05). And the body regions which work task was significant risk factor were wrist and neck region (p<0.05). 5. The results of the multiple regression analysis involving significant factors of each body region from the univariate regression analysis showed that previous symptom complaint in whole body region(p<0.001) and psychological problem in the shoulder, elbow and lumbar region (p<0.05) were significant factors, and work task was significant factor in the wrist (p<0.05).

Purpose : To investigate the medical information related to HRT online and the medical treatment of perimenopausal and postmenopausal women in the Dept. of Ob&Gy Korean Medicine Hospital, after the discontinuance of the WHI trial in U.S, July 2002. Methods : With the key-words "HRT", "Hormone Replacement therapy", "호르몬 대체요법(HRT)", 갱년기 증후군(perimenopausal syndrome)", “폐경기후증후군(postmenopausal syndrome)", I searched for the information from July 2002 to 2005 on DAUM, the representative portal site in Korea, and I've got a grasp of the tendency of the informational propagation on HRT. Moreover, I investigated chief complaints and tendency of give up HRT of the perimenopausal and postmenopausal women(aged between 47 and 60) who visited Dept. of Ob&Gy Korean Medicine Hospital for 2 years and 6 months since July 2002. Results : 1) Searching for the news on DAUM, I found; 2 articles on the methods of HRT: 4 on the positive effects of HRT: 4 on the general items including the positive effects of HRT: 19 on the side effects of HRT: 1 on the insignificant effect of HRT :4 on the apprehensions about HRT: 3 on the strengthening of the criteria on medical fees review: 3 on the discontinuance of HRT: 8 on the alternative materials and medicines to HRT: 4 on the guidance for the phyto-estrogen. 2) I analyzed chief complaints of 120 women. The majority of chief complaints were vasomotor symptoms like hot flush and sweating. There were only 4 patients who wanted to give up HRT. Conclusion : The side effects of HRT were objectively dealt with online but there was not enough effective and continuous guidance. In the case that a woman not on HRT wishes to overcome perimenopausal period through KM therapy, this information may have affected her decision. However, not many women who were already on HRT terminated the therapy for fear of side effects and switched to KM therapy. Promotion of KM therapy in improving health during perimenopausal and postmenopausal period is desperately needed.

This study was done to determine the relationship between the anxiety levels of hospitalized psychiatric patients and various influencing variables. The purpose of this study was to determine factors that may help hospitalized psychiatric patients to experience lower levels of anxiety in relation to changing situations and provide the basic data for a dynamic approach which is important in the field of modern psychiatric nursing that understands and analyses the meaning of patients behavior. The anxiety may produce stress, which is a common experience among all human beings. Patients may merely feel uncomfortable in the state of mild anxiety, however, the severe state could be an obstacle to treatment and recovery from disease. The anxiety of the psychiatric patient is a factor which greatly influencing the patient's behavior, so his disorderd behavior is an expression of defence or pathologically fixed behavior. According the psychiatric patient's anxiety at the time of admission is the concern of the health team. The nurse's special concern has to do with understanding and supporting the patient and meeting his individual needs by frequent close contact during the entire hospitalization period, compared to other teamembers the nurse's responsibility in this regard is greated. So this study emphasizes the necessity of creating conditions these, but above all the psychiatric nurse should create a therapeutic environment by not only regarding the patient's behavior or symptoms but understanding the meaning of them. The subjects of this study were 57 psychiatric patients selected from the K neuropsychiatric hospital located in Kunsan city. Data were collected twice from the same patients within a 24 hour period after admission and 10 days after admission. (September 18th to November 8th, 1980). The data collected method was through direct interview, and the interview time was 20 minutes for each patient. Data analysis included Item Analysis & Internal Consistency Reliability Tests, Percentages, t-test, analysis of variance and stepwise multiple regression analysis. The findings of this study were as follows. A. Test of Hypothesis a. Hypothesis 1 :“The anxiety level of psychiatric patients within 24 hours after admission will be higher than those of the same patients 10 days after admission,”was accepted. (t = 3. 15 ; p < 0.005) b. Hypothesi 2:“The more the number of admissions the higher the level of anxiety related to two categories”, was accepted.

Antidepressants are widely used to treat depression in Korea, however, only a few studies have focused on the provider of the treatment. The aim of the study is to compare the differences between patients who were prescribed antidepressants by psychiatrists and those who were prescribed antidepressants by non-psychiatrists in South Korea. Patients with a diagnosis of depressive disorder who had been newly prescribed antidepressants in 2012 were selected from the Health Insurance Review and Assessment Service database. They were classified into two groups depending on whether they received the antidepressant prescription from a psychiatrist or non-psychiatrist. Sociodemographic, clinical, and depression related cost has been investigated. Treatment resistant depression, which is defined as a failure of two antidepressant regimens to alleviate symptoms, was also investigated. Prescription adequacy was assessed based on whether a regimen was maintained for at least 4 weeks. Among the 834694 patients with pharmaceutically treated depression (PTD) examined in this study, 326122 (39.1%) were treated by psychiatrists. Patients who were treated by psychiatrists were younger and had more psychiatric comorbidities than those treated by non-psychiatrists. They had longer PTD duration (229.3 days vs. 103.0 days, p < 0.05) and a larger proportion of treatment resistant depression (9.3% of PTD) when compared to those patients treated by non-psychiatrists. The patients treated by psychiatrists had a smaller proportion of inadequate antidepressant use compared to those patients in the non-psychiatrist group (44.5% vs. 65.1%, p < 0.05). The costs related to depression corrected with PTD duration were higher in the non-psychiatrist group (32214 won vs. 56001 won, p < 0.05). Patients who receive antidepressants from psychiatrists are patients with more severe, treatment-resistant depression. Psychiatrists prescribe antidepressants more adequately and cost- effectively than non-psychiatrists.
