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.

6-(3.4-Dichlorophenyl)amino-7-chloro-5.8-quinolinedione (RCK50) was tested for antifungal activities in mice systemically infected with Candida albicans. The therapeutic potential of RCK50 was also assessed in comparison with ketoconazole. RCK50 had ED_50 0.22±0.01 ㎎/㎏. Ketoconazole as a positive control had ED_50 6.00±1.70 ㎎/㎏. Intraperitoneally administered RCK50 at the ED_50 for 7 days and 14 days reduced Candida albicans colony count in the kidneys and liver. And administered RCK50 at the ED_50 for 14 days improved survival rates. The genotoxicities of RCK50 had been evaluated. RCK50 was negative in Ames test with Salmonella typhimurium and chromosomal aberration test in CHL cells. RCK50 did not show any clastogenic effect in mouse peripheral blood and was negative in mouse micronucleus assay. These results indicate that RCK50 has no genotoxic potential under these experimental conditions. Acute oral toxicity studies of RCK50 were carried out in ICR mice of both sexes. RCK50 did not show acute oral toxicities and LD_50 values were over 2.850 ㎎/㎏ in ICR mice.

Fries rearrangement has been known as highly useful reaction for the synthesis of ortho-or para-hydroxyacylbenzene from phenyl ester in the presence of Lewis acid catalyst. Conventionally, aluminum chloride was used as catalyst. For obtaining N-(4-acetyl-3-hydroxyphenyl)acetamide, 3-acetamidophenyl acetate was subjected to Fries Rearrangement reaction using aluminum chloride. Although the desired N-( 4-acetyl-3-hydroxyphenyl)acetamide was obtained, yield was very low. In addition, regioisomer N-(2-acetyl-5-hydroxyphenyl)acetamide and unexpected N-(2-methyl-4-oxo-4H-chromen-7-yl) acet-amide were obtained. NMR study and conversion to known compollnds confirmed the substitlltion pattern of these phenylacetamides and the structure of chromen-4-ones. Under this Fries Rearrangement condition, formation of chromen-4-one was newly discovered.

The basic investigation on ZnS:P_rF_3 thin film electroluminescent devices was done, the phosphor(ZnS:P_rF_3) and the insulator(SiN_X:H) of which were deposited by electron beam evaporation and rf-plasma CVD, respectively. The red(650㎚) and blue(490㎚) light emission peaks were observed in the Electroluminescent spectrum. At the dopant concentration of 0.5mol%, the brightness of 90.6cd/㎡ was obtained under sinusoidal excitation of 1kHz.

이원화, 다계화, 네트워크 구축전략 : 일본의 대아시아 직접투자전략

조동성,이광현,이윤철,김태현 韓國國際經營學會 1995 國際經營硏究 Vol.6 No.1

본 연구는 1985년 이후 엔고와 더불어 급증한 일본의 대아시아 직접투자를 기업전략적인 차원에서「이원화전략」,「다계화전략」,「네트워크 구축전략」의 관점에서 설명하고자 한다. 여기서 이원화 전략이란 기술전파를 막기 위해 첨단기술을 요하는 고부가가치 제품은 국내에서 생산하고, 노출가능한 기술을 사용하여 생산하는 중저가 제품은 해외에서 생산함으로써 후발개도국들의 추격을 따돌리는 전략을 의미한다. 한편 다계화전략이란 투자국의 경제 발전에 따라 일본기업의 생산입지를 단계적으로 변화시키는 전략이다. 마지막으로 네트워크를 구축전략이란 일본기업이 아시아 투자가 개별적으로 이루어 지지 않고, 총체적인 경쟁우위를 향상시키기 위해 기존 해외 네트워크의 연장선 하에서 이루어진다는 것이다. 이러한 일본기업의 아시아 해외투자전략에 대응해서 전통적으로 일본으로부터 기술을 수입해 온 한국기업이 일본기업을 추격하기 위해서는「전문화전략」,「투자지역 선도전략」및「보완적 네트워크 구축전략」을 채택해야 할 것이다. 한편 한국과 같은 선발개도국을 모델로 하여 경제개발을 추구하고 있는 다른 아시아국가들 역시 본 논문을 통해 일본기업들의 전략적 의도를 파악하고, 이에 대응하기 위해「자체능력 개발전략」및「네트워크 연결전략」을 채택할 필요가 있다.

본 연구는 새로운 치과용 색체계 개발을 목적으로 현재 치과에서 사용되고 있는 Vita shade를 사용하는 9 제조사의 12종의 광중합형 복합레진과 1종의 치과용 도재의 색상을 diffuse/8° 수광 방식을 사용하는 분광색체계 (MiniScan XE plus, Model 4000S, Hunter Lab, USA)를 이용해 D65 표준광과 10도 관찰자 시야 하에서 CIE L^(*)a^(*)b^(*) 값을 측정하고 색상 범위를 분석하였다. 분석한 정보를 color sorting system을 응용한 CNU Cons Dental Color Chart의 색상 표현 방식인 T###에 치과용 수복 재료들의 범위를 적용하여 다음의 결과를 얻었다. 측정된 L^(*)a^(*)b^(*)값의 분포를 분석해 보면 L^(*)값은 80.40과 52.70 사이에, a^(*)값은 10.60과-3.60 사이에, 그리고 b^(*)값은 28.40과 2.21 사이에 분포한다. L^(*)값의 평균값은 67.40, 중앙값은 67.30이며, a^(*)값은 2.89와 2.91, b^(*)값은 14.30 과 13.90 이다. 이러한 분석을 토대로 CNU Cons Dental Color Chart의 T###의 첫 번째 숫자에 해당하는 L^(*)값의 각 숫자간의 차이는 2.0으로, 그리고 2번째 숫자인 a^(*)값의 각 숫자간의 차이는 1, 그리고 세 번째 숫자인 b^(*)값의 각 숫자간의 차이는 2로 정하였다. T555에 해당하는 L^(*)값의 범위는 66.0이상, 68.0미만으로, a^(*)값의 범위는 3이상 4미만으로, b^(*)값의 범위는 14이상 16미만으로 결정하였다. The purpose of this study is to develope new dental color-space system. Twelve kinds of dental composites and one kind of dental porcelain were used in this study. Disk samples (15 ㎜ in diameter, 4 ㎜ in thickness) of used materials were made and sample’s CIE L^(*)a^(*)b^(*) value was measured by Spectrocolorimeter (MiniScan XE plus, Model 4000S, diffuse/8° viewing mode, 14.3 ㎜ Port diameters, Hunter Lab. USA). The range of measured color distribution was analyzed. All the data were applied in the form of T### which is expression unit in CNU Cons Dental Color Chart. The value of L^(*) lies between 80.40 and 52.70. The value of a^(*) are between 10.60 and 3.60 and b^(*) are between 28.40 and 2.21. The average value of L^(*) is 67.40, and median value is 67.30. The value of a^(*) are 2.89 and 2.91 respectively. And for the b^(*), 14.30 and 13.90 were obtained. The data were converted to T### that is the unit count system in CNU-Cons Dental Color Chart. The value of L^(*) is converted in the first digit of the numbering system. Each unit is 2.0 measured values. The second digit is the value of a^(*) and is converted new number by 1.0 measured value. For the third digit b^(*) is replaced and it is 2.0 measured unit apart. T555 was set to the value of L^(*) ranging from 66.0 to 68.0, value of a^(*) ranging from 3 to 4 and b^(*) value ranging from 14 to 16.

This study was investigated by experimentals on the thermal behavior of stratified fluids in the square cavity with the vertical cooling surface by variation of initial temperature and cooling surface temperature and concluded as follows: 1. When the cooling surface temperature of the square cavity was -4℃. the supercooling phenomena was occurred every times regardless initial temperature of fluids and when -6℃ freezing was begun with out supercooling phenomena. 2. The higher the initial temperature was, the longer supercooling phenomena duration was, and the longer the supercooling phnomena was, the higher the temperature of the upper fluids was. 3. When the supercooling phenomena of water was occurred, the rate of temperature decrease of silicon oil was higher and when there was no supercooling phenomena, it was almost same the rate of temperature decrease.
