It has been generally known that smoking is one of the worst factor increasing disease and mortality in human health since in 1950's and nowadays. But regardless of various proofs about social or economical problems due to smoking, current smoking rate has not been decreased in our country. Until now, most of tobacco use and its addiction researches have been focused on the adolescent or adult women smokers not on the university students. Therefore, the purpose of this study was to investigate smoking cessation of university smokers and analyze the health belief-perceived sensitivity, severity, benefits and barriers- difference, then to provide basic data for effective smoking cessation strategy for university smokers. The subjects were comprised of 181 university smokers from 15 universities in Seoul. The data were collected by structured questionaires. The questionaires were designed to measure general characteristics, smoking cessation and health belief, based on Ahn(2003)'s result on the Study of Smoking attitude, Behavior and Smoking Cessation of Adult Male and Lee(1987)'s result on Relationships Between the Health Belief Model and Smoking Habits. The data were collected from May 5 to 16. The collected data were analyzed by SPSS program. The actual number, percentiles, means, standard deviation, t-test and ANOVA were done. The result of this study were as follows; 1. The general characteristics of the subjects of this study The range of age was from 18 to 34 and the averaging age was 23.

이동현(Lee, Dong-hyun),조순정(Cho, Soon-jeong) 한국경영교육학회 2020 경영교육연구 Vol.35 No.3

[연구목적] 본 연구는 대학 공시정보를 활용하여 교육국제화역량 인증(IEQAS) 여부를 예측하며, 대학의 인증 유지를 위한 자가 점검에 적합한지 연구 모형을 검증하는데 목적이 있다. [연구방법] 동 연구는 IEQAS 인증․미인증 예측을 위해 2019년 대학알리미 웹사이트에 공개된 138개 사립 대학의 공시정보를 수집했다. 이어, 인증 대학 77개교 및 미인증 대학 61개교 두 집단 간 지표 차이를 검정 후, 5개의 대학경쟁력지표 및 9개의 재정회계지표를 독립 변수로, 2019년 3월에 발표된 IEQAS 인증 결과를 이산형 종속 변수로 설정하여 이산선택모형에 따라 로짓분석과 판별분석을 하였다. [연구결과] 본 연구자들은 t-검정으로 선별한 재학생충원율/신입생충원율/전임교원확보율(이상 대학경쟁력), 학생1인당교육비/교육비환원율/부채비율/법인전임급비율(이상 재정회계)을 연구 모형에 유의한 요인으로 투입했다. 그 결과, 대학경쟁력 지표를 통한 예측력은 로짓분석 71.7%, 판별분석 71.0%로, 재정회계 지표의 경우 로짓분석 70.3%, 판별분석 66.7%의 예측력을 보였다. 동 이산선택모형 내에 공통으로 관여한 유의미한 변수는 재학생충원율, 신입생충원율과 학생1인당교육비로 나타났다. [연구의 시사점] 동 연구는 조직의 부실 여부 예측에 유용한 로짓분석과 판별분석을, 정부의 대학별 공개 자료를 활용하여 IEQAS 인증․미인증 예측에 적용해 본 가치를 지닌다. 본 연구의 이산선택모형은 타당성과 신뢰성이 확인됨으로써, 대학이 손수 IEQAS 인증 유지 점검 시 활용할 수 있으며 대학 평가에 관한 경영교육 실무에 기여할 것이다. [Purpose] Based on a discrete choice model(DCM), this study aims to predict the ‘pass/fail’ of the International Education Quality Assurance (IEQAS) by analyzing publicly opened dataset. Thus, it will enable Korean universities to self-test their IEQAS-related capabilities in a productive manner. [Methodology] This work utilized disclosed data on academyinfo.go.kr in 2019, including a total of 138 private universities from My university competitiveness(MUC), Financial accounting index(FAI); relying on related literature, it proposed two hypotheses and 14 independent variables, followed by conducting logit analysis(LA) and discriminant analysis(DA). [Findings] First, t-tests identified three MUC variables(Levy with enrolled students; Levy with new students; Faculty in full service) and four FAI variables(Educational expenditure; Educational restitution rate; Liability ratio; Corporate transferred money) between 77 IEQAS ‘pass’ group and 61 IEQAS ‘fail’ group in 2019. This DCM presented the following predictive powers: 71.7%-LA vs 71.0%-DA in MUC and 70.3% -LA vs 66.7%-DA in FAI, while Levy with enrolled students, Levy with new students and Educational expenditure worked as keys to predicting the ‘pass/fail’. [Implications] The DCM combining LA/DA can be used for both scholars on the business education area and the IEQAS-related practitioners.

We provide various fundamental statistics for PM-10 based on air quality monitoring data('96-'98) operated by the Ministry of Environment. The purposes of this paper are to examine the distribution of PM-10 level computed on the basis of a reference method adapted by USEPA and to review national ambient air quality standards for particulate matter in Korea. When we calcualted the 3-year('96-'98) average of the annual mean PM-10 concentrations at 24 monitoring sites. 21 sites were not met 50㎍/m(annual PM-10 standard in USA). Especially. Duckchon-dong and Shinpyung-dong sites at Pusan were recorded the highest concentration. Also, when we considered the 3-year average of the 99^(th) percentile values, 14 sites including Ssangmun-dong at Seoul and Duckchon-dong at Pusan among 23 were classified non-attainment area exceeding 150㎍/m(24-hour PM-10 standard in USA). We suggest that the air quality standards for PM-10 and PM2.5 in Korea must be actually regulated based on scientific review and the public health.

Purpose: The purpose of the study was to·find the strategies of mental health screening in school. Based on the literature review, we discuss the importance of screening students in schools for mental health problems. Methods: Data from the 2008 Korean Mental Health Screening in Schools(2008-KMHSS) are used to estimate the outline of this screening. We administered the questionnaire for satisfaction of 2008-KMHSS for students(N=1,280), parents(N=2,672), school nurses(N=75), teachers(N=685), district personnels(N=6), and mental health center staffs(N=37). Also we interviewed a part of them by telephone and e-mail. And we reviewed the tools and methods for screening students for emotional/behavioral problems. Results: Mental health screening in schools is a very important, yet worrisome, agenda that is in its very early stages. From the 2008 Korean Mental Health Screening in Schools, 9,588 students(12.9%) needed more evaluation in the first stage. Of these, 6,910(72.1%) completed the second stage screening. In this sample, 1,975(28.6%) utilized the mental health services in school or community. 38.3% of students and 43.7% of their parents notified the2008-KMHSS. But only 12.1% of students and 10.9% of their parents dissatisfied with the screening. 9.9% of teachers and 22.7% of school nurses dissatisfied with the screening. Among them the school nurses were mostly dissatisfied, and they complained work burden from KMHSS. Mental health center staffs complained similar issues. The Children's Problem-behavior Screening Questionnaire(CPSQ) and Adolescents' Mental-health & Problem-behavior Screening Questionnaire(AMPQ) were compatible to screen students in schools for mental health problems in first stage. Conclusion: Mental health screening in schools needs careful planning and implementation. For successful mental health screening in schools, several elements need to be considered: careful planning, collaboration, staff training, and integrative mental health programs and services in community or schools.

Acetyl-L-carnitine (ALC), an endogenous component of the L-carnitine family, is naturally occurring molecule synthesized from L-carnitine (LC) by carnitine acetyl transferase. ALC has been shown to improve the cognitive performance of patients suffering from dementia of the Alzheimer's type and proposed for treating Alzheimer's disease in pharmacological doses. The purpose of the present study was to evaluate the bioequivalence of two ALC tablets, Nicetiler^TM (Dong-A pharmaceutical Co., Ltd.) and Neurocetil^TM (Kyung-Dong Pharmaceutical Co., Ltd.), according to the guidelines of Korea Food and Drug Administration. Twenty six normal male volunteers, 22.80±2.76 year in age and 63.07 7.98㎏ in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After one tablet containing 500㎎ of ALC was orally administered, blood was taken at predetermined time intervals and the concentrations of ALC in serum were determined using HPLC with fluorescence detector. Because of the presence of endogenous ALC, the calibration was performed using dialyzed serum. Pharmacokinetic parameters such as AUC_t, C_max and T_max were calculated and ANOVA was utilized for the statistical analysis of the parameters. The results showed that the differences in AUC_t, C_max and T_max between two tablets were 2.72%, -0.65% and -8.42%, respectively, when calculated against the Nicetile^TM tablet. The powers (1-β) for AUC_t and C_max were 94.87% and 87.17%, respectively. Minimum detectable differences (Δ) at α=0.05 and 1-β=0.8 were less than 20% (e.g., 15.58% and 19.16% AUC_t and C_max, respectively). The 90% confidence intervals were within ±20% (e.g., -11.84∼6.41 and -10.57∼11.88 for AUC_t and C_max, respectively). Two parameters met the criteria of KFDA for bioequivalence, indicating that Neurocetil^TM tablet is bioequivalent to Nicetile^TM tablet.

The purpose of this study was to find out blood lead and cadmium concentration levels of rural residents. The blood samples were collected from 140 rural residents in 5 nonpolluted regions in Kunbuk-Myun, Kumsan-Gun, Chungnam province from August 31 to September 30, 1990 and analyzed by atomic absorption spectrophotometry. The results were summerized as follow : The mean concentration level(range) of blood lead was 0.240±0.060㎍/ml(0.130-0.390㎍/ml) for males and 0.237±0.056㎍ /ml(0.120-0.370㎍/m) for females. There was no statistically significant difference among age groups and sexes. The distributions were similar to normal distribution in both sexes. The mean concentration level(range) of blood cadmium was 0.066±0.099㎍/ml(0.012-0.582㎍/ ml) for males and 0.060±0.062㎍/ml(0.015-0.392㎍/ml) for females. There was no statistically significant difference among age groups and sexes. The distributions were skewed to the low level ranges in both sexes. The lead concentration level in whole blood did not show statistically sinificant difference among kinds of farming product. But the cadmium level of the rice-ginseng-tobacco farmers was statistically significantly high (p<0.005). The cadmium concentration level in whole blood was 0.040±0.027㎍/ml for the rice-ginseng farmers, 0.076±0.100㎍/ml ofr the rice-tobacco famers, and 0.158±0.171㎍/ ml for the rice-ginseng-to-bacco farmers. There were no statistically significant difference in blood lead and cadmuim concentration levels among groups classified by drinking habit, smoking habit and exposed years to pesticides. The correlation coefficent between the blood lead and cadmium concentration levels was statistically significant(R=0.2054, P<0.05).
