Objectives: There are many habitual drinking in rural area. So it is the key point of drinking control policy in rural community to understand the drinking behavior in leisure time and to have an appropriate screening method for problem drinking. CAGE and AUDIT are famous screening tools for problem drinking and alcoholics. Even though there are some studies to validate CAGE and AUDIT which translated in Korean, they were not studied with community based population but with hospital based patients. In this study we assessed the usefulness of CAGE and AUDIT for selecting problem drinking in a rural population, and compared problem drinkers with normal group about spending leisure, Methods: The study subjects were 120 residents over 20 years old who lived in 3 districts in Dong-San Myun near Chun-chon city. We made up questionnaire by interview from Feb. 13 to 19, 2004. Results: The mean age of study population was 66.01 .26 years old. Defining the problem drinking as more than 12 score in AUDIT and more than 2 score in CAGE, the proportion of problem drinker was 30.600 and 28.9% respectively. This proportions were higher than those of other national wide studies. There were significant difference in drinking frequency per week and amount per one episode between problem drinker and normal group. Experience about driving, accident, injury, disturbance in working and quarrel after drinking were also significantly different. Problem drinker were more tolerable to the bad social culture about drinking (eg. force to drink, bad drunken habit. overdrinking, drinking relay etc.) than normal group. Watching TV and playing with neighborhood were most frequent method of spending leisure in this study population, normal male group exercised more frequently in leisure time than problem drinker. Conclusions: It may be useful to use CAGE and AUDIT score for screening problem drinking in rural community. Appropriate utilization of leisure time may he important for control of problem drinking in rural area.

This study was conducted to examine housewives' knowledge level of herb medicine and its related factors in Korea. Data were collected from 667 housewives from April 1, 1999 to June 30, 1999. The results of this study are summarized as follows. 1. According to general characteristics of the subjects, 29.1$\%$ of the subjects was over fifties. 28.6$\%$ was primary school graduate. while 25.5$\%$ was high school graduate. In case of job, the unemployed was 67.0$\%$ and professional／clerical worker was 19.6$\%$. 82.0$\%$ had spouses and 45.7$\%$ believed in Buddha. 50.8$\%$ of the subjects lived in big cities and 76.7$\%$ was the middle class. In case of their health condition, 33.4$\%$ was in good health, while 5 1.1$\%$ suffered from certain diseases and 43.9$\%$ was not satisfied with health conditions. 2. The proportion of experience in taking herb medicine was 86.4$\%$. The marital status and health condition were significantly related to the experience in taking herb medicine. When the respondents took diseases, 68.0$\%$ of them were experienced in folk remedy. The variables of age and religion were significantly related to experience in folk remedy. 3. According to the respondents opinions of the effect of the folk remedy, 'effective' was 78.5$\%$ and 'common' was 17.6$\%$, while 'not effective' was 3.9$\%$. 59.3$\%$ of the respondents thought that the folk remedy had scientific basis. 4. In case of information sources on herb medicine, 59.7$\%$ of the respondents obtained the information from TV or Radio. 13.7$\%$ of them got it from magazines related to Oriental medicine and 13.3$\%$ of them obtained it from newspapers or related books. The information sources were significantly related to age and health condition. The knowledge level of herb medicine was 20.76${\pm}$2.66 point on the basis of 30 points. The knowledge level was significantly related to age, occupation, health condition, information sources, experience in taking herb medicine, and opinions of scientific basis of the folk remedy. 5. The respondents marked 2.23${\pm}$0.64 points on the basis of 3.0 points in the question of the effect of taking herb medicine in summer, 2.30${\pm}$0.61 points in the question of the relationship between taking deer antlers and becoming clear-headed, 2.72${\pm}$0.56 points in the question of ginseng, 2.51${\pm}$0.56 points in the question of the relationship between taking herb medicine and being harmful to the liver, 1.94${\pm}$0.74 points in the question of taking herb medicine during the period of pregnancy, 1.84${\pm}$0.78 points in the question of the relationship between menstrual irregularity and motherwort, 2.00${\pm}$0.83 points in the question of the relationship between taking herb medicine and getting fat, 1.76${\pm}$0.89 points in the question of the relationship between Ssanghwatang and cold, 2.15${\pm}$0.76 points in the question of taking honey, and 1.45${\pm}$0.77 points in the question of selecting foods during the period of taking herb medicine. 6. The factors influencing decision of taking herb medicine were experience of taking herb medicine, intention of receiving treatment by folk remedy, occupation, health condition, and age. As seen in the above results, the knowledge level of taking herb medicine during the period of pregnancy, the relationship between menstrual irregularity and motherwort, Ssanghwatang, honey, and selecting foods during the period of taking herb medicine was very low. Therefore, it is necessary to develop education programs in order to provide community residents with basic knowledge of herb medicine. In doing so, the government, Oriental medical doctors, and associations related to herb medicine must make great efforts.

This paper presents a 'consequence analysis' for vapor cloud explosions caused by heavy gas leakages from commercially used storage tanks at petrochemical plants. Particularly, this paper emphasizes on evaluating the results of various vapor cloud explosion accidents from Butane storage tanks. Also this paper analyses the impact of variables on the accidents in order to acquire the optimum conditions for variables. $SuperChems^{TM}$ Professional Edition was applied to analyse the impact (If atmospheric and other variables in the situation where vapor cloud continuously disperses from the ground level. Under the assumption that practical operating conditions are selected as a standard condition, and Butane leaks from the storage tank for 15 minutes, the results show that the maximum distance of LFL (Lower Flammable Limit) was 52 meters and overpressure by the vapor cloud explosion was 1 psi at 128.2 meters. It is observed that the impact of the variables on accidental Butane storage tank leakage mainly varied upon atmospheric stability, wind velocity, pipe line size, visible length, etc., and changes in the simulation result occurred as the variables varied. The maximum distance of the LFL (Lower Flammable Limit) increased as the visible length became shorter, the size of the leak became larger, the wind velocity was decreased, and the climatic conditions became more stable. Thus, by analysing the variables that influence the simulation results of explosions of Butane storage tanks containing heavy gases, I am presenting the most appropriate method for 'consequence analysis' and the selection of standards for suitable values of variables, to obtain the most optimal conditions for the best results.

Purpose: This study was conducted in order to investigate children's Nutrition Quotient (NQ) and the degree of keeping the Dietary Guidelines of children and their mothers and to further examine the relationships between children and mothers. Methods: The subjects were 281 children from 4th to 6th grade in an elementary school located in Gwangju and their mothers. Results: NQ of the children was $66.8{\pm}14.2$, which was in the third (medium) grade. Among the five factors, the scores for Moderation and Diversity were in the second (high) grade, but those for Regularity, Practice, and Balance were in the third grade. Children of non-working mothers had significantly higher scores for NQ and Balance than those of working mothers. Children of mothers with age over 40 had a significantly higher score on Diversity than those with mothers under age 40. Children of mothers with higher education showed higher score for Regularity than those with lower education. Children from high-income families had higher score for Moderation. The score for children keeping the Dietary Guidelines was $78.8{\pm}10.5$ and children of non-working mothers showed higher score than those of working mothers. The score for mothers practicing the Dietary Guidelines was $80.6{\pm}9.4$ and non-working mothers and mothers with age over 40 had higher score. Children's NQ showed significant correlation with the score for keeping the Dietary Guidelines for children (r = 0.789, p < 0.001) and also with that of mothers (r = 0.235, p < 0.001). Conclusion: These results show that NQ of elementary school children in Gwangju is in the medium grade, the degree of practicing the Dietary Guidelines for children is pretty fair, and these factors are influenced by their mother's socioeconomic characteristics such as employment, age, education, and family income.

OCR(On channel repeater) provides the high frequency reuse efficiency for allocating frequency bands to repeaters because the frequency of input and output signals of OCRs is the same. However the oscillation probability of OCRs is high due to the same input and output frequency. In order to prevent a repeater from oscillating, we must keep the antenna isolation higher than the gain of the repeater with a some margin. In this paper we simulated the effects of the amplitude, phase and time delay of feedback signals (m the characteristics of non-regeneration OCR. Simulation results show that the highest probability of oscillation is occurred when the gain of a repeater is the same value of the isolation. From the simulation results, we know that the phase of feedback signals can be adjusted to reduce the possibility of oscillation if a non-regeneration repeater has a narrow operation bandwidth or a signal bandwidth is narrow. As the time delay increases, the probability of oscillation and the fluctuation of gain over a certain frequency band increase also. The effects of the amplitude and phase of feedback signals on S/N of 8-VSB signal for generation and non-generation repeater were tested. The measured results show that the set-top can receive 8-VSB signal when the received signal power is $17{\sim}18dB$ higher than the noise power. When the isolation is almost same as the gain of the repeater, then the set-top can not receive 8-VSB signals due to the oscillation of the repeater. And the phase of feedback signals affects S/N at the output of the repeater when the isolation is $11.75{\sim}13.75dB$ larger than the gain of the repeater. In this case the set-top can not receive 8-VSB signal of at $48^{\circ}\;and\;347^{\circ}$ of the phase of feedback signals. However the phase of feedback signals can not affect the S/N of 8-VSB signals of the generation repeater because of the demodulation and modulation process of the generation repenter. The set-top can not receive 8-VSB signals when the amplitude of feedback signals is $12.6{\sim}13.6dB$ larger than the wanted signal power at the input port of the repeater. It's because that the amplitude of feedback signals saturates the front end of the repeater.

Purpose : The identification of specific behaviors conducive to overeating or inactivity is the cornerstone of obesity management. The Committee on Nutrition of the Korean Pediatric Society developed parent and self-reporting questionnaires about eating behavior and physical activity in 2006. The aim of this study was to evaluate the usefulness of the questionnaires in assessing modifiable lifestyle factors related to obesity. Methods : A retrospective chart review was performed for 177 children (6-11 years old) and 134 adolescents (12-16 years old) from 10 hospitals between May 2006 and January 2007 who had completed parent or self-reporting questionnaires. Cases were divided into normal and overweight groups at or above the age-gender-specific 85th percentile based on 2007 Korean national growth charts. Results : Compared to children, the adolescents tended to have a significantly more sedentary lifestvle and inappropriate dietary behaviors significantly (P<.05). Overweight mothers were significantly associated with overweight children and adolescents (P<.05). Being overweight was significantly associated with a family history of adult diseases for children and adolescents (P<.05). Inappropriate eating behaviors (strong appetite, eating fast, eating until they were full, binge eating, favoring greasy foods) were associated with being overweight in children and adolescents. Sedentary activity such as TV viewing and using a computer were significantly associated with overweight in children and adolescents (P<.05). Conclusion : Intervention to modify obesity-related lifestyle factors is needed before adolescence. These questionnaires are useful in identifying modifiable lifestyle factors and in individual counseling for overweight children and adolescents in pediatric clinics.

Today, cultural content industry could be defined to service business rather than manufacturing business because of its own trait. Also, it has the realistic restriction that it can't hold the dominant position in the market competition when it can't provide consumers satisfaction regardless of its quality or degree of completion. In other word, it can only expect great success when the business plan and the activities get the perfect balance with its best quality and perfect of completion. As the result, it emphasizes the importance of business competition in the global market. In briefly, there is no doubt that the creativeness of content is very important in the cultural content industry but in the future, making system to maintain the distribution process and share the profits fairly will be taken more important role. Especially, animation genre has the feature, which compares to other genres, such as film or TV drama, would be free from cultural barriers, and it is a great advantage. So to speak, animation can get little influence from cultural discount. However, Korean animation can't use the advantage properly for the foreign distribution because of its poor infrastructure and short of professional human resources. For those reasons, it has been needed to set up the realistic and specific action plan to overcome the situation. Therefore, considering those needs and the situations of Korean animation facing, making B2B online marketplace could be a great solution. The online marketplace stands for taking more efficient and broad distribution channel instead of the passive way, which we have now. If we have the B2B online marketplace, we can share all the information about the Korean animation with the potential customers whom live outside of Korea at real time. It also could be use to the windows of multiple distribution, which can make additional profits and activate the optional markets for the Korean animation. Through the method, Korean animation would be expected to get the higher international competitiveness, and it would be developed in quality and quantity of the business. Finally, it would be a great chance to Korean animation, which can get the unique brand power by improving the backward distribution circumstances.

Purpose: We are trying to analyze 130 patients' conditions by using our Helical Tomotherapy, which was installed in our center in Oct. 2007. We will be statistically approach this examination and analyze so that we will be able to figure out adaptive plans according to the change in place of the tumor, GTV (gross tumor volume), total amount of time it took, vector (${\upsilon}=\surd$x2+y2+z2) and the change in size of the tumor. Materials and Methods: Objectives were the patients who were medicated with Tomotherapy in our medical center since Oct. 2007 August 2008. The Average age of the patients were 53 years old (Minimum 25 years old, Maximum 83 years old). The parts of the body we operated were could be categorized as Head&neck (n=22), Chest (n=47), Abdomen (n=25), Pelvis (n=11), Bone (n=25). MVCT had acted on 2702 times, and also had acted on our adaptive plan toward patients who showed big difference in the size of tumor. Also, after equalizing our gained MVCT and kv-CT we checked up on the range of possible mistake, using x, y, z, roll and vector. We've also investigated on Set-up, MVCT, average time of operation and target volume. Results: Mean time on table was 22.8 minutes. Mean treatment time was 13.26 minutes. Mean correction (mm) was X=-0.7, Y=-1.4, Z=5.77, roll=0.29, vector=8.66 Head&neck patients had 2.96 mm less vector value in movement than patients of Chest, Abdomen, Bone. In increasing order, Head&neck, Bone, Abdomen, Chest, Pelvis showed the vector value in movement. Also, there were 27 patients for adaptive plan, 39 patients, who had long or multiple tumor. We could know that When medical treatment is one cure plan, it takes 32 minutes, and when medical treatment is two cure plan, it takes 40 minutes that one medical treatment takes 21 minutes, and the other medical treatment takes 19 minutes. Conclusion:With our basic tools, we could bring more accurate IMRT with MVCT. Also, through our daily image, we checked up on the change in tumor so that adaptive plan could work. It was made it possible to take the cure of long or multiple tumor, the cure in a nearby OAR, and the complicated cure that should make changes of gradient dose distribution.

Purpose : Today, people usually die in hospitals and institution-sterile and strange, and equipped with a complex range of technology capable of supporting and prolonging life, frequently only biological one, when a return to health and vitality is no longer possible. Consequently, 'dying with dignity' has become a slogan of opposition to useless and degrading prolongation of life when a patient's organ, though still minimally functional, can no longer support or permit the exercise of self-fulfilling personal control over life's events. Dying with dignity, however, means entirely different things to different people. This study is to investigate the college students' attitude on terminal care and passive euthanasia. Methods : During June 1997, 337 college students participated in this study by responding to the pre-made questionnaire. It deft with the attitude to passive euthanasia, hospice, the most suffering fear facing the death, the preferred place and person to be with if dying. Results : 63.2% of subjects agreed to passive euthanasia. Only 14.2.% of college students can explain the concept of hospice, exactly They got the information about hospice by TV(43%), book(33.5%), religious group(12%) in order. The preferred death place was home(76.6%) and hospital(11.9%) in order. The Most suffering fear facing the death were about unknown(41.5%), loosing colleague(13.6%), pain(11%), isolation(6.5%) in order. Conclusion : About two-thirds of college students agreed to passive euthanasia. But euthanasia is dangerous and unnecessary. We should vigorously promote programmes of education in hospice and palliative medicine and care.
