  • Objectives : This study was conducted to investigate the prevalence of victims of bullying and the demographic characteristics of victims, and their related psychopathology, in a Korean nationwide sample of youths in middle and high school over a one month period. Methods : During the autumn of 2009, students in the 7th to 12th grades at 23 secondary schools participated in a nationwide, cross-sectional study. The study subjects completed the Adolescent Mental Health and Problem Behavior Screening Questionnaire-II (AMPQ-II) and Symptom Checklist-90-Revision (SCL-90-R). Based on the data acquired, descriptive statistics, correlation coefficients and multiple logistic regression analysis were performed. Results : Among the 3364 participants, 2272 (67.54%) completed the questionnaire. The prevalence of victimization was 28.9%. Male gender was positively associated with victimization, and grade level was negatively related to victimization. The AMPQ-II bullying score (Factor 4) was significantly (p<.001) and positively correlated to the AMPQ-II student total score (r= 0.50), Worry and thought (Factor 1 ; r=0.38), Mood and suicide (Factor 2 ; r=0.31), Academic and Internet-related problems (Factor 3 ; r=0.24), Rule violations (Factor 5 ; r=0.23), and AMPQ-II teacher total score (r=0.11). Somatization (r=0.23), Obsessive-compulsive behavior (r=0.24), Interpersonal sensitivity (r=0.30), Depression (r=0.33), Anxiety (r=0.26), Hostility (r=0.30), Phobic anxiety (r=0.22), Paranoid ideation (r=0.36), and Psychoticism (r=0.31) results from the SCL-90-R were also found to be positively related to the AMPQ-II bullying score, and remained significant after adjusting for age and gender. A total of 26% of the victims reported suicidal ideations as compared to 9% of non-victims over the month prior to the evaluation ($x^2$=119.595, df=1, p<.001). The multiple logistic regression analysis indicated that the AMPQ-II bullying score significantly increased the risk of suicidal ideation [Exp(b)=1.55, df=1, p<.001] after adjusting for age and gender. Conclusion : School bullying was highly prevalent among Korean middle and high school students. This study provided strong evidence that suicidal ideation and psychopathology were serious problems among the victims of bullying.

  • I. Introduction Since the 1970's drug abuse among young people has increasingly become a social problem in Korea. In the 1980's, drug abuse, especially glue sniffing, has become the cause of many unfortunated incidents resulting in harm to others as well as the abusers themselves. Taking into consideration of the seriousness of this problem, the Republic of Korea National Red Cross initiated a nation-wide research programme, to understand the present situation and to raise the level of public awareness. The goal of this research was to begin a nation - wide campaign against drug abuse. The research team was composed of the Advisary Committee members and the staff of the Youth Department of the Republic of Korea National Red Cross. The data were collected in February 1988 with the collaboration of the staff and volunteers in the local Chapters. The respondents were allocated nation-wide by the quota sampling method. The questionnaires were distributed to the respondents in three groups :2, 700 to junior and senior high school students, 605 to working youths, and 916 to delinquent youths. A total of 4, 221 questionnaires were collected. II. Characteristics of the Respondents The respondents in each group were selected evenly from rural and urban areas. The general characteristics of the respondents can be described as follow: in case of students, the proportions between male and female respondents, and between senior high school and junior high school students were almost evenly distributed. In case of working youths, the proportion of females (80.5%) was higher than those of the students and the delinquents groups. Delinquent youths were defined as those currently being under custody of the centers for juvenile delinquents. Of this number, 38.8% and 68.2% were junior and senior high school drop-outs respectively. The majority of them (92.6%) were male. As for the family background of the respondents, the proportion of those residing in poverty - stricken areas, and the proportion of those from broken families were higher in case of working youths and delinquent youths than those in case of students. III. Present Patterns of Drug Abuse The following summarizes the presents of drug abuse, as tabulated from the results of the survey. 1. Smoking The percentage of youths who smoke was 36% in the student group, 32% m the working youths group, and 94.4% in the delinquent youths group. 2. Alcohol 50.3% of students, 71.6% of working youths, and 93.3% of delinquent youths has experienced drinking alcohol beverages. 3. Tonic: non - alcoholic, caffeinated beverages popular in Korea and Japan The percentage of those who have used tonic at least once was over 90% in all of the three groups. 4. Sedative About 70% of each group has used sedative with the proportion of working youths use higher than those in other groups. 5. Stimulants Those who have used stimulants comprised around 15% in each group. 6. Tranquilizers Somewhat less than 5% of students and working youths, and 28% of delinquent youths, have used tranquilizers. 7. Hypnotics The users of hypnotics amounted to 0.4% of students, 2.6% of working youths and 7.1% of delinquent youths. 8. Marihuana Those who have used marihuana indicated 0.7% of students, 0.8% of working youths, and 13% of delinquent youths. 9. Glue-sniffing The percentage of glue-sniffing was 3.7%, 5% in the students group and in the youths group respectively, but the proportion was unusually high, at 40.7% in the delinquent youths group. From the results of the survey the present situation of drug abuse in Korea can be summarized as follows: 1. A high percentage of Korean youths have experienced smoking cigarettes and drinking alcoholic beverages. 2. Tonics (non - alcoholic, caffeinated beverages), antipyretic analgesics and stimulants quite regularly used. 3. Tranquilizers, hypnotics, marihuana and glue-sniffing are more widely used among delinquent youths than the other youths. From this fact, there exists a correlation between drug abuse and juvenile delinquency. IV. Time-series Analysis of the First Experience of Drug Abuse and Deviant Behaviour The respoundents were asked when they were first exposed to drugs and when they committed deviant acts. By calculating the average age of each experience, the following pattern was found (See Figure 1). Youths are first exposed to drugs by abuse of tonic(non - alcoholic, caffeinated beverages). At the age of 13, they amoke cigarettes, the use of antipyretic analgesics begins at 14 year old, while at the age of 15, they use tranquilizers, and at 16 hynotics. The period of drug abuse which starts from drinking caffeinated beverages and smoking cigarettes and ends in the use of hypnotics takes about three years. During this period, other delinquent behaviours begin to surface, that is, at the age of 13 when smoking cigarettes begins, the delinquent behaviour pattern starts with truancy. Next, they start taking money from others by using physical force. Prior to the age of 15, they are suspended from school, become hostile to adults, begin running away from home, and start using stimulants and alcohol. Soon they become involved even in glue-sniffing and in the use of marihuana. At the age of 15, they begin to see adult videos and carry weapons. Sexual promiscuity and usage of tranquilizers follows the viewing of adult videos. Consequently, by the time they reach the age of 16, they visit drinking establishments, and are picked up by police for committing delinquent acts. And finally, they come to use hypnotic - type drugs. From the above descriptions, drug abuse can be assumed to have a close correlation with delinquent behaviour. V. Social Factors Related to Drug Abuse As for the Korean youths, glue-sniffing is found to he related to aggressive delinquency, in such cases as run - aways, being picked up by the police, and taking money by force. Smoking cigarettes and drinking alcohol is found to be related to seeing adult videos and visiting drinking establishments. Hypnotics and marihuana were found to be representive of drugs which are related to degenerational delinquency, irrespective of social delinquency. The social factors connected with these drug abuse are as follows: 1. Individual factors Male students were more heavily involved in the usage of drug than females. Youths who do not attend church were more likely to be involved in drugs than those who attend. 2. Family factors The youths who were displeased with their mothers smoking and those who thought their parents did not love each other, or those whose parents had used drugs without prescription, were more likely to he drug users. 3. School factors Those youths who found school life boring, were unsuccessful in their studies, spend most of their time with friends, feel their teachers smoke too much, those who had a positive perception of their teachers smoking were likely to he drug users. To sum up, drug abusers depend on the influence of their parents, teachers and peers. IV. Reasons for Drug Abuse Korean students have mainly used drugs to release stress (42.8%), to stay awake (19.7%), and because of the easy accessibility of drugs( 16.6%). Other reasons are due to their ignorance of the side effects of the drugs (3.6%), natural curiosity (4.2%), and to increase strength(3.O%). From the above facts, the major reasons for drug abuse among Korean youths are to release stress and to stay awake in order to prepare exams. Furthermore, since drugs are readily available, we can conclude that drug abuse is caused by the school system(such as entrance exams) in Korea. VII. Conclusion Drug usage among Korean youths are relatively less common than those of western youths. In some cases, such as, glue-sniffing and use of stimulants, the pattern of drug abuse is found. Moreover, early drug abuse is evident, and it has a close connection with deviant behaviour, resulting in juvenile delinquency. Drug abuse cannot be attributed to any one social factor. Specifically, drug abuse depends on parents, peers, teachers and other members of the community, and also is influenced by social institutions such as the entrance exam system. Every person and organization concerned with youth must participate collectively in restraining drug abuse. Finally, it is suggested that social agencial working for youth welfare should make every effort to tackle this serious problem confronted by the Korean youths today.

  • This is a cross-sectional descriptive correlation study that aimed to understand the relationship between the level of sexual contacts during the dates and psycho-social factors in teenage girls who have or had boyfriends. The purpose of this study was to describe the relationship between sexual contacts and self-esteem and self- assertiveness. The subjects of the study were 6,130 teenage girls who have or had boyfriends. They were selected convienently 12,733 teenage girls from 254 secondary schools located in 7 large cities and 9 provinces in Korea. A structured questionaire was used it included items one general characteristics, the levels of sexual contacts, self-esteem and self-assertiveness. Seven levels of sexual contacts were rated they were holding a hand, putting arms around each other's shoulders, kiss, french kiss, touching breast, petting genitalia, and sexual intercourse during the dates. Self-esteem and self-assertiveness were measured by the "Self-esteem scale" of Rogenberg (1971) and the questionaires developed by S. B. Chang et al(2000), respectively. The self-reported questionaires were collected from October 2, to October 28, 2000 and analyzed by using SPSS 10.0 Program. The data were analyzed by descriptive statistics, reliability, One-way ANOVA with Duncan method & Scheffe method. The results of the analysis were as follows. 1.An average Percentage of the respondents who have (46.1%) or had (53.9%) boyfriends was 48.1% (n=6,130) and the most common sexual contact during the dates was french kiss (26.7%, n=1,634). While 7.5%(458) of respondents had a sexual intercourse, 13.7%(842) of respondents didn't have any sexual contact during the dates. 2. Distribution of starting point of the first sexual contact demonstrates that 1,950 respondents (31.8%) held partner's hand at the first date and 1,367 respondents (22.3%) put arms around each other's shoulders at the 2nd or 3rd date. Sexual contacts such as kiss, french kiss, touching breast, petting genitalia, or sexual intercourse were experienced mostly at the later than the 10th date. However, surprisingly large number(1.7%) of respondents had genital contact and sexual intercourses at the first date. 3. The means of self-esteem and self-assertiveness socres of the respondents who have or had boyfriends are 27.43$({\pm}4.03)$ and 17.96$({\pm}2.55)$, respectively. The range of scores for self esteem was 10-40, 40 with most self esteem. The range of scores for self assertiveness was 7-21, 21 with most self assertiveness. 4. As sexual contacts proceeded, the means of self-esteem and self-assertiveness values decreased. In detail, the respondents having no or light sexual contacts (kiss, putting arms around each other's shoulder, holding a hand) had similar self-esteem values($p{\leq}0.05$). However, ones having relatively intensive sexual contacts (french kiss, touching breast) showed significantly lower self-esteem values($p{\leq}0.05$). Same trend has been obtained for self-assertiveness value. 5. The higher values of self-esteem and self-assertiveness values the respondents had, the later they started the moderate sexual contact (kiss, french kiss) during the dates. Interestingly, among the respondents having intensive sexual contacts (petting genitalia, sexual intercourse) during the dates, those who experienced the such contacts at the first date or later than 10th date have higher self-esteem and self-assertiveness values than one experienced the such contacts during the 2nd$\sim$9th dates, giving U-shape curve. 6. There was a significant relationship between self-esteem and self-assertiveness in girls who have or had boyfriends($P{\leq}.001$). In conclusion, the research shows that self-esteem and self-assertiveness values are significantly related with the sexual contacts of the teenage girls who have or had boyfriends. These results strongly suggest that proper sex education program for teenage girls should contain the program on improving the self-esteem and self-assertiveness. We believe that sex education program is the one of the best ways to prevent the unwanted sexual contacts and pregnancy of teenage girls.

  • This survey study was conducted on dental technician school students in April 2008 to investigate the effects of smoking on oral health. 110 male and 39 female students were surveyed and cross analysis was performed to examine the relationship between oral health status and smoking-related and oral health maintenance characteristics of smoking and non-smoking group. T-test and one-way ANAVA was used to analyze the average difference verification of two independent samples(smoking group and non-smoking group) and followings are the results. In general characteristics, 74 male students(74.7%) and 25 female(25.3%) students smoked and the percentage of male students were higher in smoking group. Regarding class grade, 2nd-year students(37 students, 37.4%) and 1st-year students(18 students, 36.0%) took the highest percentage of smoking and non-smoking group, respectively. Concerning the experience of drinking, smoking group consumed more alcoholic beverages(94 students, 94.9%) With respect to the frequency of between-meal consumption, respondents who eat between-meal once or twice smoked more. Respecting preferences of sweet food, respondents who enjoyed sweet food smoked more. Concerning smoking characteristics, many of smoking group had been smoked fo a long time(two to five years) and it was worrisome. About the amounts of smoking, 50 respondents(52.6%) of smoking group smoked 20 cigarettes a day with the highest proportion. With regard to the awareness of harmfulness, 70 respondents(70.7%) considered smoking as very harmful and showed that smoking group were aware of its harmfulness but it was habitualized. Respecting smokers in family members, father was more common as smokers(58 respondents, 58.6%) in family and showed that the influence of father. Main reasons of poor periodontal health were alchoholic consumption, smoking, and oral parafunctional habit(57 respondents, 56.7%) in smoking group and neglect of oral hygiene(21 respondents, 42.0%) in non-smoking group. With regard to the scaling, 80 respondents of smoking group(80.8%) didn't received scaling and showed that more oral health education was required. Regarding the periodontal status, non-smoking group was $1.26{\pm}0.44$, respondents who received scaling was $1.43{\pm}0.50$, respondents who regularly floss was $1.50{\pm}0.52$, respondents who brush more than three times a day was $1.38{\pm}0.49$ and had better periodontal health. Bleeding during tooth brushing was more frequent in smoking group ($1.51{\pm}0.70$). Regarding mouth order, non-smoking group was $2.34{\pm}0.62$, after scaling was $2.02{\pm}0.76$, patients who regularly floss was $1.50{\pm}0.52$, patients who brush more than three times a day was $1.81{\pm}0.87$. Concerning the experience of dental caries treatment, smoking group was $1.20{\pm}0.40$, patients who do not floss was $1.30{\pm}0.46$, patients who brush once a day was $1.29{\pm}0.45$. With regard to dental prosthesis, non-smoking group was $3.78{\pm}1.62$, patients who received scaling was $1.43{\pm}0.50$, patients who regularly floss was $1.40{\pm}0.51$, patients who brush more than three times a day was $1.24{\pm}0.43$. From these results, oral health education and smoking has correlation and more oral health education needs to be carried out to educate students with non-health related majors about harmfulness of smoking on oral health. Also more study are required.

  • 농촌노인이 일상생활에서 느끼는 고독감과 우울의 정도, 사회적 지지를 파악한 기술적 조사연구이다. 본 연구의 구체적인 목적은 첫째 노인의 일반적 특성과 상담자의 유무 및 삶의 중요한 것의 상실체험, 우울, 고독감 및 사회적 지지를 파악하고, 둘째 고독감과 일반적 특성과 상담자의 유무 및 삶의 상실경험과의 관련성을 보며, 셋째는 고독감과 우울 및 사회적 지지와의 상관관계를 분석하였다. 65세 이상 농촌지역 재가노인을 대상으로 무작위 표본추출방법을 사용하여 추출된 32개 표본지점 지역의 노인 전체를 대상으로 2001년 1월 10일-25일로 약 15일간 훈련된 대학생 5명이 직접 노인의 가정을 방문하여 면접조사하였다. 우울도구는 우울척도단축판(실부직미(失富直美), 1994)을 사용하였으며, 고독감에 대한 도구는 개정판 UCLA고독감척도(공등력타(工藤力他), 1983)를 사용하였고, 사회적 지지는 사회적 지지도구(Duke대학, 1995)를 사용하였다. 조사도구의 신뢰도는 Cronbach's ${\alpha}$값이 우울척도 0.3775, 고독감 척도 0.2974, 사회적 지지척도 0.8756이었다. 분석방법은 SPSS+프로그램을 이용하여 빈도 및 평균값을 계산하여 실태를 파악하였으며, 유의성의 검정을 위하여 는 $x^2$-검정, t-검정 및 F-검정하였다. 노인조사대상자는 486명으로 남자가 49.0%, 여자가 51.0%이었으며, 평균 연령이 73.9세였다. 자신의 일을 상담할 수 있는 사람이 있는 노인은 58.0%이었으며, 상담자는 "배우자"와 "동거자식, 며느리"가 대부분을 차지하였다. 최근 자신이 중요하게 여긴 것이 없어졌다는 상실경험은 조사대상노인의 56.2%였는데, 주로 "아프다"는 것으로 건강상실과 "배우자와의 사별"과 "친지의 죽음"이 높은 순위를 차지하였다. 조사대상노인의 고독감은 $34.54{\pm}8.38$점이며, 우울점수는 평균 $7.23{\pm}2.21$점으로 다소 우울상태에 있었고, 사회적 지지점수는 평균이 $26.01{\pm}0.90$점이었다. 고독감에 영향을 미치는 요인은 성, 연령 및 상담자의 유무로 남자노인이 여자노인에 비해 고독감이 낮았으며 (p<0.001), 연령별로는 연령이 낮을수록 다소 낮았고 (p<0.05), 자신의 일을상담할 수있는 노인이없는 노인에 비해 고독감이 낮았다(p<0.001). 우울은 성, 연령, 상담의 유무, 상실경험의 유무와 관련이 있었는데, 남자노인이 여자노인에 비해 다소 기분이 좋은 상태이었으며(p<0.01), 연령이 높아짐에 따라 우울해지는 것을 볼 수 있었고(p<0.001). 상담자가 있는 노인이나 상실체험이 없는 노인에서 우울하지 않았다(p<0.05). 사회적 지지점수는 성별로는 남자노인이 여자노인보다 높았고(p<0.01), 상담자가 있는 노인이 없는 노인보다 높았다(p<0.001). 고독감과 우울과는 유의한 정적 상관관계를 보여, 고독감이 높을수록 우울점수가 높았고(r=0.2407, p=0.000), 고독감과 사회적 지지(r=-0.2802, p=0.000), 우울과 사회적 지지(r=-0.1183, p=0.009) 간에는 유의한 부적 상관관계가 있어 고독감은 사회적 지지가 많을수록 낮아지며, 우울도 사회적 지지가 많을수록 낮아졌다. 결론적으로 노인의 고독감을 감소시키기 위해서는 지역사회 내에서 사회적 지지가 가능한 방안을 마련하는 것이 요구된다. 따라서 지역사회 자조조직의 활동이나 노인을 위한 사회지지조직을 마련하거나 기존 보건기관을 활용한 건강증진프로그램을 강화하는 방안을 고려하는 것도 필요할 것이다.

  • 중 고등학교 교사의 근골격계 불편증상과 관련 요인을 알아보기 위해 2010년 10월 1일부터 10월 15일까지 250명의 교사들을 대상으로 근골격계 불편증상 설문조사를 실시하고, 231명(남자 68명, 여자 163명)의 결과를 신체 각 부위별로 통계분석 하였다. 근골격계 불편증상의 관련요인으로 특히 주관적 건강상태가 높은 연관성을 보였고(OR 11.75, 95% CI, 3.56-38.78), 그 외 근무학교유형, 40세 이상, 2시간 이상의 가사노동시간, 8시간 이상의 VDT작업시간, 휴식여부가 유의한 상관성이 있는 요인들로 분석되었다. NIOSH 기준에 의한 근골격계 불편증상 호소율은 36.8%였고, 각 부위별 불편증상 호소부위와 빈도는 목 60명(26.0%), 어깨 70명(30.0%), 팔/팔꿈치 16명(6.9%), 손/손가락 31명(13.4%), 허리 35명(15.2%), 다리/발 17명(7.4%)으로 목과 어깨의 발생빈도가 높았다. 목 부위는 주관적 건강상태와 휴식유무, 어깨부위는 주관적 건강상태와 성별, 손/손가락 부위는 연령, 허리부위는 주관적 건강상태와 연령, 다리부위는 주관적 건강상태와 연령, VDT작업시간이 관련성 있는 요인들로 분석되었다. 사무직근로자에서 근골격계 질환은 간단한 스트레칭만으로도 예방 가능하다. 신체 각 부위별로 간단하고 적절한 운동을 통해 자신의 건강상태를 유지하고 올바른 작업 자세와 작업요건을 갖추고 작업시간 중간에 충분한 휴식시간을 가짐으로써 직무로 인한 근골격계의 과도한 긴장과 불편감 발생을 낮추기 위한 스스로의 노력이 필요하다.

  • 국내 듀록 품종 종돈의 교류현황과 또한 유전자원 교류가 국가단위의 유전능력평가에 미치는 영향을 평가하고, 돼지개량네트워크 사업을 통한 돼지개량 전략 마련을 위한 기초자료를 수집하기 위하여 한국종축개량협회의 등록 및 검정 자료를 분석하였다. 자료는 세 곳의 등지방 두께(어깨, 등, 허리)와 등심단면적, 90 kg 도달일령 그리고 일당증체량 형질을 포함하고 있으며, 1987년부터 2010년까지 총 235,511건의 등록 자료와 70,747건의 검정자료를 이용하였다. 수집된 듀록 자료를 분석한 결과, 종돈장간의 유전자원의 교류는 극히 미미한 수준으로 나타났다. 등록 후에 검정까지 수행 되어진 자료의 수는 더욱 적은 것으로 나타났고, 유전능력평가를 위해 필요한 일정규모의 두 수를 가진 종돈장의 수는 더욱 적었다. 혈연관계의 이용정도에 따라 세 가지 분류의 자료(개별 종돈장, 두개의 종돈장 그룹, 전체 종돈장)를 이용한 유전능력 평가 및 유전 모수의 추정에 있어서, 개별 종돈장 분석에서 종돈장간에 유전모수추정에 있어 거점 종돈장에 비하여 종속 종돈장의 유전력이 높은 경향을 보여 주었다. 유전력 추정 오차는 개별 종돈장, 두 그룹, 전체 집단 순으로 작게 나타났다. 유전분산이 종속 종돈장들에서 크게 나타남으로써 종속 종돈장들의 유전적 균일성이 거점 종돈장들에 비해 낮은 것으로 나타났다. 근친계수의 추정에서 차이를 보였으며, 개별 종돈장, 거점 종돈장과 종속 종돈장, 그리고 전체 집단을 평가하였을 때 각각 평균 근친이 1.12, 0.95 그리고 1.53으로 나타나 종돈장 간의 혈연관계를 고려한 전체 집단 평가에서 근친이 높았다. 추정된 육종가에 의한 상관계수에서 개별농가의 평가와 전체평가간의 상관이 가장 낮았다. 반면에 sub-population 평가와 개별농가 평가, 그리고 전체 평가는 이보다 상관이 높게 나타났다. 그러나 농장별 평가와 전체평가간의 상관계수가 이동된 종돈에서 형질별로 0.22에서 0.45, 그리고 전체 종돈에서 0.24에서 0.72의 범위로 비교적 낮게 나타났다. 연구된 결과들은 개별 종돈장 평가 보다는 국가단위의 유전능력평가가 혈연관계를 더 많이 이용하고, 돼지개량네트워크 사업이 종돈장간의 연결성을 증대시켜 국가단위 유전능력평가의 정확도에 기여한다고 사료된다.
