We Koreans are very proud of this nation's cultural history over some five millenniums. But most of the relics found in the nation date back up to two thousand years. Under this circumstance, we are wondering the gap and missing of three thousand years. In our traditional literature of history, [Chiwoo] was a military god of supreme dignity and virtue. He was a symbol of brave and strong warriors and since the antiquity, he has been kept alive deeply in the mind of the Korean race. Considering findings through this study, the researcher could provide a conclusion as described below. 1) The name of Paekje's designed tiles was initially made by a Japanese scholar who had first found the antique relic. According to studies by a few of Korean researchers, the name is usually called despite its relation with a historical background of the excavated objects has not been fully studied. 2) After the patterned objects of the Korean antique Kingdom, Japanese researchers reported that [Chiwoo] was a military god as exorcist and probably represented something in the form of a ghost, although there were arguments that the military god was the very being to influence the image of the ghost. This report suggests that the Japanese community didn't downgrade the military god onto the level of a ghost. 3) One of our antique nations, Paekje at that time sought to determine the origin and culture of the Koreans by making multiple exchange relations with China, and probably accepting cultures of the Chinese Han nation and those of the Chinese South and North Dynasty period. Based on findings from a relevant literature, [Sulyigi], people of Paekje attempted to show express the image of Chiwoo in their own unique ways and then deliver the strong bravery of [Chiwoo] to us, or their descendents. This can explain that those findings as above mentioned are consistent with the designed tiles of Paekje, and that the tiles should not be named as the design of ghost. 4) The designed tiles involved elements of Taoism and Buddhism and substantially considered the spirit of four gods which was mobilized for the tomb construction and selection at that time. But this should never be a reason why all of the horned figures seen in tomb wall paintings are collectively treated as ghosts. 5) From the view of historic literature, we can no doubt say that the Heavenly Emperor [Chiwoo] was our ancestor. It is not better to say that the relic stuffs as excavated should be referred to the design of ghost image only in that they have yet to be associated historically with other relics. This claim would be newly changed as it becomes clear with historical remains that our antique ancestors kept doing positive activities along the coast of the antique kingdom, Balhae.

Objectives: Poisonous substances experts engage in policymaking regarding poisonous substances, whereas poisonous substances managers perform legal duties related to poisonous substances management systems at worksites. To understand and improve poisonous substances designation systems, it is necessary to distinguish the roles of these experts and managers. We further aimed to identify problems with poisonous substances appointment systems and provide basic data for their improvement by investigating the knowledge and recognition of the need for system improvement among managers and experts. Methods: To determine the $subjects^{\circ}{\emptyset}$ awareness of poisonous substances designation systems, a selfadministered questionnaire comprised of items on general characteristics and knowledge and recognition of the need for system improvement was issued. Data were analyzed via t-tests and ANOVA using SPSS v 16.0 Results: Regarding system comprehension, managers (n=213; mean 3.28, SD 0.63) significantly differed from experts (n=35; mean 4.08, SD 0.59) (P<0.001). No differences were found in recognition of need for improvement between managers (mean 3.11, SD 0.34) and experts (mean 3.24, SD 0.31). Significant differences in comprehension were found among managers by education level (P<0.05) and company size (P<0.05). Regarding industry type, comprehension was greater in the electrical/electronic and chemical/environmental industries compared to in other industries (P = 0.066). Comprehension was higher among those with five years or more of experience compared to those with less than five years. Regarding recognition of need for improvement, managers showed significant differences by company size (P<0.05). $Experts^{\circ}{\emptyset}$ comprehension showed no differences by general characteristics, while need for improvement differed according to work experience (P<0.001). Conclusion: The study found that the bigger the company size, the higher the level of comprehension by managers and the experts. In the case of both groups, where a higher comprehension of the poisonous substances designation system was evident, they recognized the necessity of its improvement.

Background: The association of biomaterial combined with repair factor-like platelet-rich plasma (PRP) has prospective values. Bovine-derived xenograft has been identified as an osteoconductive and biocompatible grafting material that provides osseointegration ability. PRP has become a valuable adjunctive agent to promote healing in a lot of dental and oral surgery procedures. However, there are controversies with respect to the regenerative capacity of PRP and the real benefits of its use in bone grafts. The purpose of this study was to assess the influence of PRP combined with xenograft for the repair of peri-implant bone defects. Methods: Twelve rabbits were used in this study, and the experimental surgery with implant installation was performed simultaneously. Autologous PRP was prepared before the surgical procedure. An intrabony defect (7.0 mm in diameter and 3.0 mm deep) was created in the tibia of each rabbit; then, 24 titanium dental implants (3.0 mm in diameter and 8.5 mm long) were inserted into these osteotomy sites. Thus, a standardized gap (4.0 mm) was established between the surrounding bony walls and the implant surface. The gaps were treated with either xenograft alone (control group) or xenograft combined with PRP (experimental group). After healing for 1, 2, 3, 4, 5, and 6 weeks, the rabbits were sacrificed with an overdose of KCl solution. Two rabbits were killed at each time, and the samples including dental implants and surrounding bone were collected and processed for histological analysis. Results: More newly formed bone and a better bone healing process were observed in control group. The histomorphometric analysis revealed that the mean percentage of bone-to-implant contact in the control group was significantly higher than that of the experimental group (25.23 vs. 8.16 %; P < 0.05, independent-simple t test, analysis of variance [ANOVA]). Conclusions: The results indicate that in the addition of PRP to bovine-derived xenograft in the repair of bone defects around the implant, PRP may delay peri-implant bone healing.

The purpose of this study was to examine the health knowledge, attitude and behaviors of Korea high school students and find out the relationship between knowledge, attitude and behaviors in an effort to lay the foundation for the development of health-promotion programs and health education for adolescents. The subjects were 505 students in their first and second year of high school in Gangnam-gu and Guro-gu, Seoul. After a survey was conducted for seventeen days from April 23 to May 9, 2003, with self-administered questionnaires, the collected data was encoded and analyzed with SPSS Win 11.0 program. The frequency, percentage, mean and standard deviation were calculated, and χ²-test, t-test, ANOVA, Scheffe Post Hoc Tests and Pearson Correlation procedure were employed. The findings of this study were as follows： 1. There appeared significant differences in general traits, family-related characteristics and health-related features between the students in Gangnam and the others in Guro. 2. The collective average of the Gangnam residents in health knowledge was 13.97, and that of the Guro residents was 14.64. The overall collective average was 14.35(total of 22 points), and 65.2 percent of the students investigated had a correct knowledge. The points showed significant differences in the variables of sex, economic status, mother's occupation,and health concerns. 3. The students from Gangnam scored a mean of 77.55 in health attitude, and the others from Guro got an average of 78.75. The overall collective average was 78.22(total of 110 points), and 71.1 percent took a correct attitude toward health. The points showed significant differences in the variables of sex, religion, mother's education level, health concerns. 4. In the field of health behavior, the Gangnam residents got a mean of 63.99, and the Guro dwellers scored a mean of 62.12. There was a significant gap between the two groups, and the overall collective average was 62.94(total of 102 points). 61.5 percent tried to stay fit in a correct behavior. The points showed significant differences in the variables of sex, economic status, parents' education level, father's occupation, health concern of parents, self-perceived health status, health concern, exercise or diet performance for health, health education times for 1yr. 5. Concerning the relationship of health knowledge to health attitude and behavior, the health knowledge showed significantly positive correlation with health attitude(r＝0.227, p＜0.01), and the health knowledge showed significantly positive correlation with health behavior(r＝0.262, p＜0.001). But their relationship is comparatively low. The health attitude was not significantly correlated to health behavior.

$\lceil$도산십이곡$\rfloor$의 $\lceil$언지$\rfloor$ 제6종장에는 '어약연비'가 나온다. 이 시어는 흔히 이황의 성리이것은 이황의 문학을 이해하는 주요 어휘로 생각된다. 이 어휘는 이황의 사상과 문학이 만나는 접점의 기능을 수행하고 있다는 점을 보이고자 한다. 먼저 시경과 중용의 원문을 보고 정호와 주희의 주석을 살핀다. 원문과 해석 사이의 틀을 주목한다. 이를 이황이 수용한 양상과 시작품의 내용을 살핀다. 사상과 문학이 만나는 지점을 고찰한다. 이어서 이언적과 이이가 그 어휘를 사용한 방법과 비교해 이황 문학사상의 특징을 드러낸다. 연비어약은 언어를 넘어서는 유학의 절대적 경지를 대표하는 어구이다. 이는 $\lceil$시경$\rfloor$ 본래의 뜻에서는 벗어났지만 $\lceil$중용$\rfloor$ 이후로 궁극적 실체로서의 도체를 형용하는 관습구가 되었다. 궁극적이고 절대적인 경지를 언어로 나타낼 수 없는 것은 불교나 도교에서 뿐 아니라 유학에서도 마찬가지이다. 그리고 그럼에도 불구하고 언어로 나타낼 수밖에 없음도 마찬가지이다. 연비어약은 바로 그러한 점을 드러내기 위해 사용되었다. 연비어약 자체가 언어로 나타낼 수 없는 본체를 언어로 표현한 것이라서, 이론적 설명과 시적 형상화 양쪽으로 나타나게 마련이었다. 그러나 이론적 설명으로는 어떻게 해도 그 궁극처를 형용할 수 없으므로 시적 형상화는 필연적인 것이다. 연비어약 자체를 시로 수용하려는 노력이 이언적이나 이황 같은 주리적 성향의 성리학자에게 나타난 것은 자연스럽다. 그러나 이황은 언어를 넘어서는 경지라 해도 도덕적 경지를 벗어나지 않는다는 해석을 보여준 것으로 특이하다. 연비어약을 자연의 생기의 활발함에서 그치지 않고, 자연이 위와 아래의 질서를 구현하고 있는 것으로 파악하였다. 자연이 그러하듯이 인간에도 상하의 질서가 엄존함을 보고 있는 것이다. 불교에서라면 솔개가 물 아래 놀고 물고기가 하늘을 난다고도 할 수 있을 것이라는 이황의 지적은, 불교에 대한 정확한 이해이면서 그것으로는 인간 사회의 질서를 마련할 수 없다는 데서 오는 불만을 드러낸 것이다. 이황의 생각에 유학은 불교의 그 경지를 포함하면서 사회 구성력을 갖는다는 점에서 더 낫다는 것이다. 이황이 연비어약에 많은 관심을 기울이고 여러 편의 시로 나타낸 이유가 여기 있다. 사 계절의 질서와 연비어약의 약동이 둘이 아니라 하나임을 아는 것이 $\lceil$도산십이곡$\rfloor$ 시가 드러내고자 하는 이치이다. $\lceil$도산십이곡$\rfloor$은, 살아서 만물을 낳으면서 동시에 질서와 조화를 구현하는 세계의 근원적 모습을 사람들이 알기를 바라는 마음을 드러낸 시이다. 그 점을 자연과 고인의 길을 통해 알 수 있다고, 알아야 한다고 설득하면서 자연과 도덕을 융화하고 있는 시이다.

조직연구에서 개인 직무, 개인-조직, 개인-환경 사이의 부합수준은 성과에 대한 주요한 영향요인으로 다루어져 왔다. 개인-조직이 추구하는 가치부합수준은 조직의 구성원으로 하여금 동기유발의 주요한 요인으로 조명되고 있다. 그러나 이런 부합수준 성과관련 연구에서 부합수준별 성과, 혹은 성과의 극대화률 설명하는 만족적 부합수준을 경정하기 위해 적용가능한 방법론의 개발관련 연구는 미미한 수준이다. 기존 연구에서 이런 부합수준-성과 간의 관계를 연구하는데 활용되는 지표들은 두 프로파일의 요인별 차이값, 차이제곱값, 차이 절대값, 측정 도구 사이의 상관관계를 나타내는 Q 값, 두 프로파일 사이의 순위상관을 나타내는 $Q_r$이다 그러나 이런 지표들은 두 프로파일의 부합수준 성과간의 관계를 연구하는데 많은 한계를 보여주고 있다. 특히, Edwards의 단일 설명변수에 대한 다항회귀분석과 반응표면분석을 활용한 방법론은 두 프로파일의 개별 설명변수 차이 값의 종속변수에 대한 영향만을 개별적으로 보여주고 설명변수를 모두 고려할 경우 차이 프로파일을 구성하는 개별요소별 성과를 극대화하는 값이나 수준이 어떠해야 하는지에 대해서는 해답을 주지 못하고 있다. 따라서 본 연구는 이러한 문제의 해결을 위해 다변량 이차다항회귀 모형을 적용하여 다중반응표면분석을 통해 개인-조직, 부합수준-성과 간의 관계를 검증하였다.

The purposes of this study were to survey the present situation of nutrition education in junior/senior high school, to analyze the difference between the favorite subjects on students and the existing subject done by dietitians on nutrition education, and then to identify the subjects of nutritional education for junior/senior high school students. Self-administered questionnaires were given to dietitians and students and 142 of the 200 dietitians (71.0%) and 479 of the 564 students (84.9%) responded to the questionnaire on the nutritional education. According to the survey results, 76.1 % of school dietitians currently were doing nutrition education for students while the other 23.9% didn't have such education programs even though they recognized the necessity strongly. The target of nutrition education was student rather than parents or teacher generally and the principal measuring method for nutrition education effect was change of plate waste and leftover'. It was found that significant difference in the collector and source of nutritional education information between junior and senior high school dietitians (p< .05) . About ninety-eight percentage of dietitians felt that nutrition education should keep pace with meal service and this meant that almost respondent recognized the necessity of nutrition education for students. Because the most serious one among operational problems of nutrition education program was lack of enough time owing to too many affairs as dietitian, junior and senior high schools should support so that dietitians would share enough time for nutrition education. And also, a gap was existed between actual and favorite subjects on nutrition education. Significant differences existed in the following subjects; 'basic concept of food and nutrition', 'disease and nutrition', 'food culture in the world', 'cooking and culinary art', 'food of the 24 divisions of the year in the lunar calendar', 'food waste and environmental issue', 'food habit and food behavior', 'exercise and nutrition' (p< .001) 'table manner', 'food and individual sanitation', 'recommended dietary allowance' (p < .01) and 'menu planning' (p< .05) .Finally, 24 subjects of nutritional education were selected based on the survey results. These subjects would be expected to be able to contribute the effective and interesting nutrition education program for junior and senior high school students.
