The purpose of this study was to investigate the relationship between the burden on families who live with an elderly person suffering from senile dementia, and the degree of their depression. There were 400 participants in this study, staying in the Seoul and Kyonggi areas from August 1, 1997 to February 28, 1998. Among the group, 100 participants took care of their patient at home, and another 300 participants left 100 patient at a day-care center, 100 sanatorium for senile dementia(asylum for helpless elderly people), 100 an infirmary for elderly people. Eventually 242 subjects out of the 400 were selected for the data analysis. The Zarit (1980) tool was employed to measure the degree of burden and Zung's(1965) “Self-Rating Depression Scale” was employed for the data analysis. The data was analyzed, and the percentage, t-test, ANOVA and Person's Correlation Coefficient were calculated. The results are as follows : 1. The average degree of burden that care-giving families felt was 49.13, which is somewhat high. 2. The average degree of depression that care -giving families felt was 51.95, which is relatively high. 3. The degree of burden was directly affected by the relation with the patient(F＝2.48, P＜.05), and the socio-economic status of the family(F＝5.17, P＜.05). Its also affected by the patient's educational status(F＝2.17, P＜.05). 4. The degree of depression of the family was significantly dependent on sex(t＝-2.05, P＜.05), age (F＝2.99, P＜.05), the relationship with the patient(F＝3.65, P＜.01), socio-economic status (F＝7.74, P＜.001), occupation(t＝2.82, P＜.01), health status(F＝4.42, P＜.01), and the place of residence(F＝4.30, P＜.01), The patient characteristics was significantly dependent on his/her educational status(F＝3.85, P＜.01), the period of suffering from senile dementia(F＝2.47, P＜.05), and smoking habit(F＝6.17, P＜.001). 5. The relationship between the degree of burden and that of depression reads r＝0.43, which is statistically positive correlation in the high significant level. Upon analyzing the entire summation, most care-givers for elderly patients suffering from senile dementia lack time in caring for themselves. They also experience chronic fatigue and mental discomfort caused by the isolation from society, curtailment of certain activities, a sense of responsibility for their patients, and limits of their endurance in taking care of their patients over time. In conclusion, this study emphasizes the necessity for the following propositions : 1. In order to measure the degree of burden that Korean care-giving families undergo, a new tool must be developed on the basis of Korean culture. 2. An educational program based on the demands that care-giving families undergo must be developed, and its clinical effect also has to be examined.

Background: Auricular acupressure is one of the traditional health care treatments in oriental medicine. Approximately, 30~40% of the cancer patients have said to be suffering from insomnia and half of them having chronic and severe insomnia at the same time. Insomnia caused cancer patients feel more pain, fatigue, depression and anxiety and it sometimes let the power to have the best of cancer pull down. Objective: To investigate how effective the auricular acupressure treatment to cancer patients suffering from insomnia. Methods: We recruited participants from East-West Cancer Center of Daejeon University. Finally, of the people whose age range from 20 to 75, 12 patients who got less than 40 points from the score of Oh's sleeping score (OSS) were recruited. Single-blind, randomized pilot study was performed. The treatment group received auricular acupressure treatment (AAT) on active points and the control group had received sham acupressure treatment (SAT) for five times. Sleep parameters were checked by using OSS and numeric rating scale (NRS). We checked the scale everytime, both before and after treatment. We analyzed the data statistically by using independent T-test, paired T-test and analysis of variance (ANOVA) test. (p<0.05) Results: Twelve cancer patients participated in this pilot study and there was no significant difference between control and treatment group. Only 7 of them had completed the whole treatment process, 4 patients of AAT group and 3 participants of SAT. The OSS of AAT group had increased from $34.0{\pm}4.3$ to $39.5{\pm}3.1$ and that of SAT group had increased from $38.3{\pm}3.5$ to $40.0{\pm}0.0$. There was no significant difference between them. The NRS of AAT group had increased from $6.3{\pm}2.9$, $04.8{\pm}2.1$ and that of SAT group had increased from $7.0{\pm}1.0$ to $5.0{\pm}2.6$. No significant difference was observed between them. Conclusion: Although both groups did not show significant differences, most of the experimental participants showed increasing OSS and NRS after treatments. Significant participants' number will be needed in the next study.

This study examined the burnout intermediates between Fire officials' job stress and Ego-resilience. The objective of this study is to suggest a policy that improves Fire officials' Ego-resilience. This survey was given to 365 fire officials in northern Gyeonggi-do region and the data was analyzed by correlation analysis and regression analysis using SPPS 22.0. The hypothesis is the Fire officials' burnout would be related to Ego-resilience and the effect on Fire officials' job stress regarding Ego-resilience is associated with burnout. The results of the study are that unstable work and inadequate reward affect the measure of burnout, which manifests as sarcasm and job efficacy and reduces the Fire officials' Ego-resilience that results in a positive pointing of the future, emotion control and interest. The meaning of policy is as follows: First, Fire officials need to be given confidence in their work stability. Second, they have to receive social or financial rewards. Third, they require a continuous supporting policy that solves their tension, physical and mental fatigue. Finally, developing diverse educational programs will be needed to promote their Ego-resilience.

The rivet joint has typical structural feature that can be initiation site for the fatigue crack due to the combination of local stress concentration around rivet hole and the moisture trapping. From a viewpoint of structural assurance, it is crucial to evaluate the size of crack around the rivet holes by appropriate nondestructive evaluation techniques. Lamb wave that is one of guided waves, offers a more efficient tool for nondestructive inspection of plates. The neural network that is considered to be the most suitable for pattern recognition has been used by researchers in NDE field to classify different types of flaws and flaw sizes. In this study, clack size evaluation around the rivet hole using the neural network based on the back-propagation algorithm has been tarried out by extracting some features from the ultrasonic Lamb wave for A12024-T3 skin panel of aircraft. Special attention was paid to reduce the coupling effect between the transducer and the specimen by extracting some features related to time md frequency component data in ultrasonic waveform. It was demonstrated clearly that features extracted from the time and frequency domain data of Lamb wave signal were very useful to determine crack size initiated from rivet hole through neural network.

Recently, there has been prevailing of the combined utilization (CU) with herbs and prescribed drugs in medical therapies in the world. But the information about frequency, efficacy and safety of this CU has not well known in Korea, yet. This study aimed to identify the status of CU by Koreans, and to inquire which side effects of CU represent to those people. A self-completed questionnaire survey was performed through each health examination center in twenty general hospitals and one oriental hospital. Of the initial 2,100 health examinees, 1,851 were participated in this survey, resulting in a response rate of 88.1%. The proportion of CD was 26.3%. The most commonly mentioned reason of CD was 'to promote general health and well-being' (17l persons, 35.5%). The main route of taking CD was self-purchase at drugstore or at herbs market, followed by the prescription of (oriental)physicians. 33.0% (151 persons) of those who took the CD rated it as effective. 93 respondents (19.8%) were experienced several adverse effects including nausea, fatigue, and dizziness. The growing simultaneous use of herbal products and pharmaceutical drugs by Korean consumers may be continuously increased the risk of herb-drug interactions. The medical professionals should be provided with comprehensive and up-to-date information about potential benefits and risks of herbs and prescribed drugs. In the future studies it may be recommended to deal common cold, health promotion, indigestion, headache, and hypertension for the effect and safety of the CD by well-organized prospective study design.

PURPOSE : Club dance is one of the most popular cultures worldwide and is getting popular in Korea over time. However, club still has negative awareness in the country due to the media spreading only harmful aspects of club culture. At any rate, nowadays many young aged people can easily have chances to experience clubs so we tried to find out the bad effects caused by clubs. METHOD : We conducted a survey and the number of participants who agreed to participate in this survey was 500, including both men and women. There are a total of 50 questions in the questionnaire form used by this study and the questions were divided into three categories: general(18), psychologic-related(7), social-cultural(9), and physical-related(16) questions. Data collected for this study was analyzed via frequency analysis using SPSS. RESULT : In our survey, most students who had already experienced the club culture tend to go to club once or twice a month, and they answered that they would feel bored if they were nor able to do so. In terms of social life, most respondents said that they had lower efficiency in working and studying the next day after going to clubs because of fatigue. In physical aspect, club users use then pelvis and lower back a lot while dancing. The respondents answered that they experienced muscle soreness, a loss in weight, and changes in their body as a consequence of intense dancing. They complaint pain mostly in lower limbs, so we could find out the fact that legs were primarily used for the club dance. CONCLUSION : To sum up, the club culture in undergraduate students affects on their daily living and body, and also has good effects as well as bad ones. Therefore, we need to look at the club culture positively and to improve bad effects of club culture.

Exercise can favorably influence brain plasticity by facilitating neurogeneration, neuroadaptivity, and neuroprotection. Aerobic exercise has been reported to change brain nerve growth factors (growth hormone, insulin like factor-1, estrogen and serotonin). The purpose of this study was to demonstrate the effects of aerobic exercise for 12 weeks on brain nerve growth factors in girls. Fourteen female participants in elementary school grades 1 through 3 were randomly allocated to the exercise group (EG, n=6) and control group (CG, n=8). The EG participated in 60 minutes of modified ballet exercise as aerobic training three days a week for 12 weeks. Based on comparison between groups by two-way ANOVA with repeated measures, aerobic exercise program participants experienced decreased weight (p<0.01), BMI (p<0.01), fat mass (p<0.001), fat percent (p<0.001) and increased LBM (lean body mass) percent (p<0.001). In addition, we detected that aerobic exercise decreased the level of serotonin (p<0.05) and increased the level of GH (p<0.05) and IGF-1 (p<0.05). These findings suggest that aerobic exercise programs can be an efficient intervention to change body composition, alleviate central fatigue, improve brain function, and induce brain cell proliferation in girls.

The aim of this study was to evaluate effect of implant abutment screw coating treatment on joint stability, investigating mechanical properties of these. For this study used $ExFeel^{(R)}$ external hexed implant system and $15mm{\times}1mm$ discs. Experimental group was $1{\mu}m$ TiN, TiCN, TiC coated abutment screws and discs. To know mechanical property, i evaluated adhesion strength, surface hardness, using disc, corrosion test using screw. The results were as follows : rotation angle of coated screws increased than that of non-coated screw because of lower friction coefficient, especially TiC coated screw group had the largest value, but removal torque decreased in all coated screws (p<0.05). Torque loss before and after fatigue test was the smallest in TiC-coated screws, and the largest in non-coated screws (p<0.05), and there was no statistically significant difference between dry condition and wet condition of screws because of higher surface hardness and lower friction coefficient. From the above results, TiN, TiCN, TiC coating group had high abrasion resistance, especially TiC coated group which had low torque-consuming, high rotation angle as low friction coefficient will be considered to influence on implant abutment screw joint stability positively.

1. Objectives This paper was tried to find out the clinical use of Gwanjung-tang by comparing patients' chief complain and natural symptom. 2. Methods The study was researched as clinically with medical records of 88 patients who visited a certain oriental medicine clinic which is in Seoul during January, 2000 and June, 2006. 3. Results 1) The male patient who was treated with Gwanjung-tang(寬中湯) is rare. The rate of patients who visited clinic in her forties is 27.3%, in fifties is 18.2%, in thirties is 15.9%, in sixties is 12.5%, in twenties is 10.3%. 2) Chief complain which made patients to visit clinic is a chest pain(19.3%), back pain and shoulder pain (15.9%), edema (12.5%), headache (9.1%), irregular menstruation (8.0%), dyspepsia (8.0%), fatigue (8.0%), insomnia (5.6%), menopausal disorder (4.5%), lumbago (4.5%), abnormal condition of stools (2.3%), and abnormal condition of urine (2.3%). 3) Natural symptom is classified into appetite, digestion, stools, urine, sweat, and sleep. The rate of patients who complained abnormal condition of digestion is 71.6%, of sleep is 59%, of stools is 52.3%, of urine is 47.7%, if sweat is 34.1%, and of appetite is 30.7%. 4) The rate of patients who is treated with Gwanjung-tang between thirty and forty packs is 43.2%, twenty packs is 39.7%, between fifty and sixty packs is 5.7%, between seventy and eighty packs is 2.3%, and between ninety and hundred packs is 3.4%. 5) The rate of patients who is treated with Gwanjung-tang during 15 days is 45.5%, between 16 and 30 days is 26.2%, between 31 and 60 days 7.9%, between 61 and 90 days 3.4%, between 91 and 120 days is 4.5%, and more than 120 days is 12.5%. 6) There are not many cases that chief complain was abnormal condition of digestion (8.0%), sleep (5.6%) stools (2.3%), and urine (2.3%). But the rate of patients who complained discomfort of digestion(71.6%), sleep(59%) stools (52.3%), and urine (47.7%) is significantly high. 7) According to "Sasang Sin Pyeon", Gwanjung-tang was used in To-sa-gwak-ran (吐瀉藿亂), Hae-su (咳嗽), Jeok-chui (積聚), Pyo-han -bu-jong (表寒浮腫), Chang-man (脹滿), Chil-gi (七氣), Dam-um (痰飮), Dam-goe (痰塊), Seom-jwa-yo-tong (閃挫腰痛), Bi-tong (臂痛) of Soeumin, and it is corresponds with clinical cases for various components. 4. Conclusions Gwanjung-tang is a medicine of reconciliation, and it makes Stomach to be warm and take down Yin Qi. The most important effect of Gwanjung-tang is Sun-qi(順氣). So it is considerable that Gyejibanhasenggang-tang (少陰人 桂枝半夏生薑湯), Hyangsayangwi-tang (少陰人 香砂養胃湯), and Gwakhyangjunggi-san (少陰人 藿香正氣散) is also effective to symptoms above, because these are medicines of reconciliatio.
