And so, this writer had questionaired the 400 middle-aged couples in five gus, Taejon megalopolis -Jung-gu, Seo-gu, Dong-gu, Yuseong-gu, and Taedeok-gu - from April 21, 1998 to May 10, 1998. Of them, total 209 question papers were drawn back; male 102, female 107. Analysis of the data is as follows. 1. 145(69.37%) subjects of total 209 had experience in lumbago after their sexual lives. 2. In the number of sex life a week, one or two times of lumbago incidence rate were the most rate as 41.55% and each other had a statistically significant relation (P 0.01). 3. In age and lumbago incidence rate, their thirties was 37.75% and each other had a significant relation (P 0.05). 4. In weight and lumbago incidence rate, the level of $50kg{\sim}60kg$ was highest and each other didn't have a significant relation (P 0.05). 5. In the mean time of sexual life, the period of $11{\sim}20$ minutes was 29.47% and each other had a significant relation (P 0.01). 6. In week time zone of sexual life and lumbago incidence rate, midnight was the highest rate, 36.23% and each other didn't have a significant relation (P 0.05). 7. In the lumbago incidence rate according to bedroom structure of sexual life, a bed was 38.17% and each other had a significant relation (P 0.05). 8. In the lumbago incidence rate according to sexual posture, a normal position showed the highest rate, 46.12% and each other didn't have a significant relation (P 0.05). Putting the abovesaid results together, lumbago has relation to the number of sex life a week, age, the mean time of sexual life, and bedroom structure of sexual life. Therefore, it is thought that it is necessary that middle-aged couples periodically study the educational programs to make an education for lumbago prevention, etc. the key points.

Objectives: This study investigated the relationship between smoking status and depressive symptoms among Korean adults. Methods: We used the data of 17,871 adults aged 19 years or older from the fifth Korea National Health and Nutrition Examination Survey(2010-2012). The subjects were classified as nonsmokers, former smokers, and current smokers by gender. Logistic regression analysis was used to calculate the odds ratios(ORs) and the 95% confidence intervals(CIs) for the effects of smoking status on depressive symptoms, and depression diagnosed by a doctor. Results: Compared to nonsmokers, the ORs of depressive symptoms for current smokers were 1.11(95% CI, 1.11-1.12) among males, and 1.64(95% CI, 1.63-1.64) among females. Compared to former smokers, the ORs of depressive symptoms for current smokers were 1.05(95% CI, 1.05-1.05) among males, and 1.89(95% CI 1.88-1.90) among females. Compared to nonsmokers, the ORs of depression for current smokers were 0.94(95% CI, 0.94-0.95) among males, and 1.40(95% CI, 1.39-1.41) among females. Compared to former smokers, the ORs of depression for current smokers were 1.09(95% CI, 1.09-1.10) among males, and 0.99(95% CI, 0.99-1.00) among females. Conclusions: Smoking is associated with depressive symptoms among Korean adults. Therefore, it is necessary to consider depressive symptoms with the management of tobacco control policies.

The purpose of this study was to find out the residents' consciousness of the unit plan on condominium apartment and to contribute to develop a condominium apartment unit plan in Daejeon City. This research was performed by a questionnaire survey method, 464 data was collected from apartment residents lived in about $85\;m^2$ unit with 3 rooms and the apartments was limited to the complexes within 1-4 years of the length of building at Yuseong-gu and Seo-gu. By analyzing those data, findings are as follows: 1) Residents thought living room, kitchen and bathroom were importment space in a unit plan. They needed a storage function in an entrance and a intermediate room, and Anbang(mater bedroom) so did. 2) L-DK plan type was very popular and the type of front DK with L on the floor plan was preferred. This was unique results. 3) Sub-kitchen was needed for a refrigerator of Kimchi, the location of it was related to a main kitchen and a utility. the third room was needed for library, home office and storage space. 3) Bath-tub in An-bang and showe-booth in public bathroom was preferred. This was same to the popular trend of Korean condominium apartment. 4) The enlargment remodeling of balcony was showed livingroom balcony or personal bedrooms at the time of occupancy. They needed the balcony near a kitchen or an utility to equip a storage facility. Additionally, residents were preferred to their taste rather than a choice of interior concept package services.

Background: The present study was conducted with 30 adult males in order to examine the muscle activity of the trunk and the lower extremities at diverse initial bending angles of the hip joint during bridge exercise on a stable surfaces and on an unstable surface that is widely performed for stabilization. Methods: The initial angles of the hip joint used were $0^{\circ}$, $45^{\circ}$ and $90^{\circ}$ and the subjects were divided into a matt experimental group and a balance training group. Results: In maximum values of muscle activity at different exercise methods and angles, the matt experimental group showed statistically significant differences in the muscle activity values of the rectus abdominis muscle, the erector spinae muscle, the rectus femoris muscle and the peroneus muscles between different angles while the balance training group showed significant differences only in the muscle activity values of the erector spinae muscle between different initial angles of the hip joint. The matt experimental group showed significant differences in muscle activity between initial angles $0^{\circ}$ and $90^{\circ}$, between $45^{\circ}$ and $90^{\circ}$ in the rectus abdominis muscle, between $0^{\circ}$ and $90^{\circ}$ in the erector spinae muscle, between $45^{\circ}$ and $90^{\circ}$ in the rectus femoris muscle and between $0^{\circ}$ and $90^{\circ}$ in the peroneus muscles while the balance training group showed significant differences between $0^{\circ}$ and $90^{\circ}$ in the erector spinae muscle. Conclusions: Therefore, it is thought that bridge exercises should be applied to patients using diverse methods.

Purpose: The aim of this study was to investigate the prevalence of depressive symptoms in stroke patients and to compare characteristics of different rating scales - Hamilton Depression Rating Scale (HDRS), Beck Depression Inventory (BDI) and Hospital Anxiety and Depression Scale-Depression (HAD.D)- with regard to diagnosis and severity assessment for post-stroke depression. Methods: Participants included 44 stroke patients who could communicate. At admission, all study participants received a semi-structured interview using the HDRS and a self-completed questionnaire using the BDI and the HAD-D. Pearson's correlation method was used to examine associations among the three depression scales. The BDI and HAD-D were compared based on HDRS criteria, and the sensitivity and specificity using cut-off values were analyzed. Results: The HDRS showed that 52.30% of stroke patients had depressive symptoms on the BDI and HAD-D it was 59.10%. The HDRS correlated significantly with the BDI (r=0.81, p<0.01) and HAD-D (r=0.55, p<0.01). The BDI correlated significantly with HADS (r=0.50, p<0.01). After calculating the area under the ROC curve to decide on HDRS criteria, the BDI (AUC=0.91, 95% CI: 0.83.0.99) showed a significantly larger area compared to the HAD.D (AUC=0.82, 95% CI: 0.69-0.94). The cut-off value of the BDI was 12.50 points with a sensitivity of 81.00% and a specificity of 76.20%. Conclusion: These findings show that the BDI is a useful screening test for depression that most closely predicts the HRDS score.
