It is important to control fine particles in children care centers, elementary schools, elderly care facilities and so on where vulnerable children and the aged stay during most of their time. This study has investigated $PM_{2.5}$ and $PM_{10}$ concentrations in two classrooms equipped with an air cleaner and two air cleaners, respectively and they were compared to those in a classroom without an air cleaner as well as those outdoors. Eight air cleaners which have various clean air delivery rates (CADRs) between 9.9 and $21.3m^3/min$ were tested in classrooms in two elementary schools in Seoul. Average $PM_{2.5}$ and $PM_{10}$ were $7.3{\pm}0.7$ and $45.5{\pm}4.1{\mu}g/m^3$ in classrooms equipped with an air cleaner and $4.2{\pm}0.6$ and $24.6{\pm}2.5{\mu}g/m^3$ in classrooms with two air cleaners, whereas they were $22.1{\pm}2.6$ and $109.1{\pm}9.6{\mu}g/m^3$ in classrooms without an air cleaner and $36.9{\pm}5.1$ and $74.1{\pm}10.6{\mu}g/m^3$ outdoors, respectively. $PM_{2.5}$ in classrooms could be reduced effectively by using an air cleaner or two air cleaners, because $PM_{2.5}$ was mainly infiltrated from outdoors, however $PM_{10}$ could not because $PM_{10}$ was mainly caused indoors by students' activities. Air cleaners were more effective for removal of $PM_{2.5}$ and $PM_{10}$ in classrooms with a high airtightness than those in classrooms with a relatively low one. Average $CO_2$ in classrooms was about 1500 to 2000 ppm for class hours dependent on the student number per a classroom, which was about 1.5 to 2 times higher than the standard, regardless of the use of air cleaner.

본 연구는 거부민감성과 이성관계 만족의 관계에서 인지적 측면인 인지적 정서조절과 행동적 측면인 갈등해결전략의 매개효과를 검증하여 거부민감성 모델의 적용에 대해 검토하고자 하였다. 이를 위해 서울소재 대학 대학생 668명(남 232명, 여 436명, 평균연령, 21.59세(SD=2.08))을 대상으로 변인 간 관계에 대한 매개모형을 설정하여 관계를 검증하였다. 그 결과, 거부민감성과 이성관계 만족과의 관계에서 인지적 정서조절 전략 중 적응적 정서조절 전략과 갈등해결전략 중 통합과 타협 전략의 이중 매개효과를 확인하였다. 즉, 거부민감성이 이성관계 만족과 직접적인 부적인 상관을 보여 거부민감성이 높을 경우 이성관계 만족은 낮아질 것으로 예상할 수 있다. 다만, 상황을 긍정적으로 해석하고 초점을 확대한 적응적 인지적 정서조절전략과 서로 적극적으로 문제를 해결하고자 하는 통합과 타협의 갈등해결전략을 통해 이성관계 만족에 긍정적인 변화를 가져올 수 있음을 확인한 것이다. 이러한 결과를 바탕으로 상담실제에 대한 함의와 개입방향에 대해 논의하였다.

The purpose of this study is to explore the relationships between hope, health locus of control and general health of nursing students. The subjects of this study were 161 female students of National Nursing School in Seoul. Data was collected through a questionnaire from May 11 to May 23, 1998. The tools used for this study were Hope scale developed by Miller and Power, Multidimensional Health Locus of Control Scale developed by Wallston and Wallston and General Health Scale(Modified Conel Medical Index) developed by Nam Ho Chang. Data were analysed in an the $SPSS/pc^+$ program using frequency for the demographic characteristics, 1-test and ANOVA for relationship between the variables and demographic characteristics and for it's differences of hope and general health control. Peason correlation coefficient for relationship between the 3 variables, hope, health locus of control, and general health. The results of this study were as follows ; The 1st hypothesis : that 'Between hope, health locus of control (HLC) and general health of nursing students will have positive relationship', was supported(=.2883, p=.000). The 2nd hypothesis; that 'The hope score of nursing students in HLC-internal group will be higher than others' was supported(F=5.22, p=.0063). The 3rd hypothesis ; that 'The general health of nursing students in HLC -internal group will be higher than others' was accepted(F=2.94, p=.0554). The 4th hypothesis ; that 'Hope, HLC and general health of nursing students according to demographic characteristics will be different ' was accepted in part. o In hope the more age, the higher score. o In HLC the group of non religious have higher score(t=-2.02, p=.045). o No experienced addmission was revealed HLC-internal group(t=-1.91, p=.058). o Non religious group has a tendency to dependent upon on powerful other person(t=-1.99, p=.049). o The hope score of nursing students was very high(4.49/6point). o The general health status of nursing students was vert good(92.88/114point). o Most of nursing students was in HLC-internal group(81.4%). o The most frequent complaints of nursing students was dizziness suddenly developed(68.4/114point), very nervous in small thing(67.83/114) and very nervous to others critics(68.4/114) in turn. In conclusion, the students who have high score of hope, in HLC-internal group have good general health. Hope inspiring not only makes one's good health but also makes others good health and powering hope. For good health person who are in HLC-internal group have powerful hope, keeping good health would be a good stretegy to change the student's HLC and make them good health and hope powering then it would be a good method to change the HLC to HLC-internal group.

The purpose of this study is to investigate the differences in body fat distribution between obese boys and girls in high school and the relationship between the precent of body fat and the Broca Index. The survey of data was conducted from November 3rd to the 11th in 1997. The data were analyzed by the use of a mean, standard deviation and a Pearson's correlation coefficient. Measurements of the percentage of body fat and lean body mass were made by a Bioelectrical Impedence while height, weigh and the Broca index were measured by a fatness measuring system. First, measurements of height, weight and the Broca index were made by a fatness measuring system on 1,125 1st year students and 1,076 2nd year students. The result of measurements, 216 obese boys and 100 obese girls appeared to have above 10% of the Broca index. The result of this study can be summarized as follows: 1) Obese boys and girls were grouped by the level of the Broca index as follows: boys, 110-less than 120 60.0%, 120-less than 130 20.8%, 130-less than 140 11.1%, above 140 7.4%. ; girls, 110-less than 120 44.4%, 120-less than 130 32.0%, 130-less than 140 13.0%, above 140 11.0%. 2) Obese boys and girls were grouped by level of the percentage of body fat by Bioelectrical Impedence as follows: boys, less than 20% 5%, 20%-less than 25% 34.7%, above 25% 33.8% ; girls. less than 25% 15.0%, 25%-less than 30% 43.0%, above 30% 42.0%. 3) In obese boys the Broca index score appeared to be positively related to body weight(r = .741, p<.001), the percent of body fat(r=.604, p<.001), lean body mass(r=.375, p<.001), body fluid(r=.445, p<.001l). On the other hand the percent of body fat was not a significant correlation of lean body mass (r= -.074), body fluid(r= -.073). 4) In obese girls, the Broca index score appeared to be positively related to body weight(r= .693, p<.001), the percent of body fat(r=.645, p<.001), lean body mass(r=.531, p<.001), body fluid(r=.532, p<.01), and the percent of body weight score appeared to be positively related to lean body mass(r=.206, p<.01), body fluid(r=.207, p<.01).

Education systems throughout the world encourage their students to learn languages other than their native one. In Australia, our Education Boards provide students with the opportunity to learn European and Asian languages. French, German, Chinese and Japanese are the most popular languages studied in elementary and high schools. This choice is a reflection of Australias European heritage and its geographical position near Asia. In most non-English speaking countries, English is the foreign language most readily available to students. In Korea, the English language is actively promoted by the Education Department and, in less official ways, by companies and the public. It is impossible to be anywhere in Korea without seeing the English language alongside or intermingled with Korean. When I ask students why they are learning English, I receive answers that include the word globalization and the importance of English throughout the world. When I press further and ask why they personally are learning English, the students mention passing exams, usually high school tests or TOEIC, and the necessity of passing the latter to obtain a good job. Seldom do I ever hear anything about communication: about the desire to talk with other people in English, to read novels or poetry in English, to understand movies or pop-songs in English, to chat on the Internet in English, to search for information on the Internet in English, or to email pen-pals in English. Yet isnt communication the only valid reason for learning a language? We learn our native language to communicate with those around us. Shouldnt we set the same goal for learning a foreign language? In my opinion communication, whether it is reading and writing or speaking and listening, must be central to language learning. Learning a language to pass examinations is meaningless unless those examinations are a reliable indicator of the ability of the student to communicate. In previous eras, most communication in a foreign language was through reading novels or formal letters. This required a thorough knowledge of grammar and a large vocabulary. Todays communication is much less formal. Telephone conversations, tele-conferences, faxes and emails allow people to communicate regularly and informally. Reading materials are also less formal as popular novels and newspapers are available world-wide. Movies and popular songs have added to the range of informal communication available. Finally travel has ensured that people from different cultures will meet easily and regularly. This informal communication requires less emphasis on grammar and vocabulary and more emphasis on comprehension and confidence to speak. Placing communication central to language learning has important implications for the Education system and for teachers.
