The purpose of this study is to observe the influence education experience (home, school, and mass media) on reducing practice behavior(purchasing, using, disposing and leading) of food-related wastes. The study also sought to promote strategy and suggest effective activation plans for the vitalization of behavior of reducing food-related wastes. The study subjects were 412 adult consumers who answered a structured questionnaire. The main findings are as follows: First, the scores of home education experience were 3.61±0.71, which was the highest, and 3.45±0.74 for school education experience, which was the lowest. Second, according to factor analysis, the reducing practice behavior of food-related wastes was converged purchasing, using, disposing and leading behavior. The scores of disposing behavior were 3.79±0.67, which was the highest, and 2.87±0.82 for leading behavior, which was the lowest. Third, the common variables influencing the reducing practice behavior(purchasing, using, disposing and leading) of food-related wastes were home education and mass media and the powerful variable influencing was home education. The results of this study can be used as basic data for the development of educational programs for effective food-related waste reduction.

This study was intended to examine the pattern and level of experience of voice problems and risk factors in school teacher, to offer basic data to prevent voice problems. The subjects were 180 school teachers from primary, middle, and high school teachers in C City, Chonbuk. Data were collected by questionnaires survey from April 30, 2001 to May 10, 2001. 56.6% of the subjects experienced voice problems such as "H-notes difficult"($2.68{\pm}.86$), followed by "Tired voice"($2.32{\pm}.93$), "Effortful voice"($2.27{\pm}.90$), and "Drying of throat"($2.21{\pm}.91$). According to general characteristics, smoking subjects showed higher voice problem than no smoking subjects and this difference was statistically significant(t=2.76, p=.007). According to voice related characteristics, "Speaking loudly" subjects showed higher voice problem than those no "Speaking loudly"(t=-2.02, p=.045). "Speaking effortful" subjects measured higher voice problem than those of "Speaking effortful" and this difference was statistically significant(t=-3.34, p=.001). The inspection of the relation of cause affecting school teachers showed that it had an interacting effect of voice habit, smoking, experienced voice problem, treatment(due to voice problem) experience, by staged it accounted for 55.3% of the total voice problem. The total voice problem indicated a positive correlation(p=.000). Conclusion: over half of the school teachers have experienced voice problems, higher perceived related of voice symptom and physical symptom factors. Also, because there are significant differences in voice problem according to smoking, voice habits of "Speaking loudly", "Speaking effortful", experienced voice problem, treatment(due to voice problem) experience.

The purpose of this study was to find out the status of and attitudes on drug abuse in primary school students, to provide basic data for preventing the youth from their drug abuse and contributing to improve their health. 36.0% of the students had an experience of the education to prevent from drug abuse, the students wanted to have an education on drug abuse in primary school, 71% of the subjects preferred to school nurses as the education about drug abuse, and 2.9% of the students show their intention to use drug when their friends recommend to take drug. For the experience of drinking, there was a significant difference to the degree of satisfaction at their school($x^2$=23.29, p=.001), their association with father's smoking ($x^2$=13.16, p=.001), and mother's ($x^2$=5.60, p=.018) smoking. The experience of drinking showed no significant differences according to the grade and the experience of prevention education on drug abuse. Attitudes on drug abuse according to the general characteristics showed significant differences according to the grade (t=4.10, p=.007), the degree of satisfaction at the school(t=8.86, p=.000), their association with any father's drinking(t=3.18, p=.002) and mother's(t=5.23, p=.000), father's smoking(t=3.21, p=.001) and mother's(t=31.87, p=.000), the state of drug use during the pain(t=7.18, p=.000).

본 연구는 청소년 도박문제가 자살생각과 자살시도에 미치는 영향에서 학교 청소년과 학교밖 청소년 간에 어떠한 차이가 있는지를 확인하고자 2018년 청소년 도박문제 실태조사 자료를 활용하여 최근 3개월 이내에 돈내기 게임을 경험한 학교청소년 4,982명과 학교밖 청소년 518명의 실태조사 자료를 로지스틱 회귀분석으로 분석하였다. 연구결과 첫째, 도박문제수준과 지인이나 업체에서 돈을 빌린 경험, 학업성적 저하경험, 자살생각이나 자살시도 모두 학교 청소년에 비해 학교밖 청소년이 더 심각하였다. 둘째, 돈내기 게임 때문에 업체에서 돈을 빌린 경험은 자살생각과 자살시도에 유의한 영향을 미쳤다. 셋째, 도박문제수준과 돈내기 게임 때문에 친구나 선후배에게 돈을 빌린 경험, 학업 성적 저하 경험은 학교 청소년의 자살생각과 자살시도에 유의한 영향을 미쳤다. 이를 토대로 도박으로 인한 청소년의 자살문제를 예방하기 위한 개입방안에 대해 제시하였다.

In this paper, an improved experience-based learning algorithm (EBL), termed as IEBL, is proposed to solve the nonlinear hysteretic parameter identification problem with Bouc-Wen model. A quasi-opposition-based learning mechanism and new updating equations are introduced to improve both the exploration and exploitation abilities of the algorithm. Numerical studies on a single-degree-of-freedom system without/with viscous damping are conducted to investigate the efficiency and robustness of the proposed algorithm. A laboratory test of seven lead-filled steel tube dampers is presented and their hysteretic parameters are also successfully identified with normalized mean square error values less than 2.97%. Both numerical and laboratory results confirm that, in comparison with EBL, CMFOA, SSA, and Jaya, the IEBL is superior in nonlinear hysteretic parameter identification in terms of convergence and accuracy even under measurement noise.

Objectives: To investigate the relationship between experience of hunger in childhood or adolescence and diabetes mellitus in old age. Methods: Stratified national samples of 421 men and 554 women aged 60-89 in South Korea were analyzed. Diabetes diagnosed by a doctor was used as the dependent variable. Experience of hunger in childhood was assessed with the question, "In your childhood, have you ever gone hungry with skipping a meal?" and "In your childhood, have you ever eaten porridge or some bran cake as main dish instead of rice because of lack of food?" Odds ratios (ORs) and 95% confidence interval (CI) were calculated by multiple logistic regressions. Results: ORs of diabetes by experience of hunger in childhood were 1.64(95% CI 0.95-2.83) for men and 1.58(95% CI 1.01-2.47) for women. Significant association of experience of hunger in childhood with prevalence of diabetes persisted in men after adjustment for adulthood and old age socioeconomic position indicators and other risk factors(OR 1.88(95% CI 1.04-3.41)). The effect of experience of hunger in 10-19 years was more prominent than that in less than 10 years in both gender. Conclusion: Experience of hunger in childhood or adolescence may increase the risk of diabetes in Korean elders.
