  • 본 논문에서는 휴우리스틱 자원 시간 계획을 위한 새로운 탐색 알고리즘인 Strictly Enforced Hill-Climbing (SEHC)을 제안한다. 이 탐색 알고리즘은 FF 등의 계획기에 적용되어 매우 높은 효율성을 보인 Enforced Hill-Climbing (EHC)을 확장한 것이다. EHC는 목표를 찾아가는 과정 동안 매번 현재 상태에서 그 상태보다 더 낮은 휴우리스틱 값을 갖는 첫 번째 후손 상태를 찾아 넓이 우선 탐색을 펼치는 데 반해, 본 논문에서 제안하는 SEHC는 찾아진 첫 번째 후손 상태와 같은 깊이의 나머지 형제 상태들까지 탐색을 연장하여 최소의 휴우리스틱 값을 갖는 후손 상태를 찾아낸다. 이와 같은 SEHC 탐색방법은 매 주기마다 소량의 추가 탐색을 통해 탐색의 전체과정 동안 EHC 보다 우수한 탐색경로를 유지할 수 있도록 해준다. 본 논문에서는 다양한 영역의 계획문제를 대상으로 A* 알고리즘, EHC 알고리즘 등과의 비교실험을 통해 SEHC 알고리즘의 우수성을 알아본다.

  • The object of this descriptive survey research was to provide basic information source for building objective standards of DNR (Do Not Resuscitate) that can be clinically applied, by analyzing college students' awareness and attitude toward DNR. The participants of the study were 1,267 students from one college of Daegu, South Korea. The structured survey questionnaire was used for data collection, and the survey was conducted from 1-31 July, 2010. The error and percentage was estimated by SPSS 17.0 program, and analyzed with $x^2$-test. As a result of comparing the nursing students' and non-health care major students' awareness and attitude toward DNR, the significant differences were found in the necessity of DNR, reason for supporting DNR, reason for opposing DNR, and DNR decision-maker, among the awareness dimension; among the attitude dimension, significant differences were found in implication of family DNR and self-DNR. Comparing the nursing students' and non-health care major students' awareness toward DNR related information provision, researchers have found significant differences in the necessity of giving information on DNR, timing of the DNR information provision, result of the DNR-related information provision, and guidelines for the DNR information provision. In terms of the difference in DNR's necessity recognition by the demographic information, the significant differences existed based on the religion and the history of blood donation; in terms of the differences in attitude toward DNR decision-maker, the differences were found on the religion and the number of siblings. For the attitude toward family member's DNR, the significant differences existed for the sex, age, economic status, religion, the number of siblings, the history of familial illness and death, and experience of blood donation; the attitude toward the DNR for the self was significantly differed by the sex, economic status, the number of siblings, and the history of familial illness and death. To establish the standards for DNR based on the study, we suggest more well-designed future studies.

  • The results of having studied the relationships between environmental factors and family history which affected distribution of ametropia according to departments are like these. The subjects of study were 920 persons who were the industrial high school students in Daejeon. First, When we searched ametropia degree and congenital factors, expecially in case of emmetropia, it showed that the students' parents who wore glasses amounted to 22.6% in ratio and the students' brothers and sisters wore glasses in 22.8%. But in case of the students of ametropia, their parents' rate of wearing glasses was 27.7%. The result showed that refractive error status of offsprings was related to their parents' eye condition. Second, We studied emmetropia and ametropia who used computer for over 3 hours in order to see relationships between refractive error and acquired factors. The emmetropias were 45.6%, while the ametropias were 70.1%. The result showed that it appeared 24.5% more in ametropia. In the end, refractive error can be greatly influenced by environmental factors. Third, The result of comparing distribution of ametropia with VDT using time according to each department showed the students of constructional information department had much more ametropia rate. They used computers than any other students in taking lessons and spent much more time than other department's students.

  • People have regarded animation as the subculture for childishness or children compared with other art fields. Although many such aspects changed, of course recently, animation has focused on the commercial side rather than the cultural or artistic side as usual. However, the animation of art using various experimental expression is also continuously manufactured among short animations. Therefore, the purposes of this study were to look at Quay brother's animation with an experimental and an authorial disposition rather than commercial side. And then it is going to analyze the grotesque of . Moreover, it is going to consider the meanings who are going to express with this animation through grotesque expression.

  • Recently, researches on a future position prediction of moving objects have been progressed as the importance of the future position retrieval increases. New index structures are required to efficiently retrieve the consecutive positions of moving objects. Existing index structures significantly degrade the search performance of the moving objects because the search operation makes the unnecessary extension of the node in the index structure. To solve this problem, we propose a space partition based index structure considering the mobility of moving objects. To deal with the overflow of a node, our index structure first merges it and the sibling node. If it is impossible to merge them, our method splits the overflow node in which moving properties of objects are considered. Our index structure is always partitioned into overlap free subregions when a node is split. Our split strategy chooses the split position by considering the parameters such as velocities, the escape time of the objects, and the update time of a node. In the internal node, the split position Is determined from preventing the cascading split of the child node. We perform various experiments to show that our index structure outperforms the existing index structures in terms of retrieval performance. Our experimental results show that our proposed index structure achieves about $17%{\sim}264%$ performance gains on current position retrieval and about $107%{\sim}19l%$ on future position retrieval over the existing methods.

  • Objective: The study aimed to understand the degree of improvement in damaged hair by applying mink oil. Methods: The agent used to improve hair texture is mink oil, which was applied in varying dosages (0, 1, 2, and 3 g). Hair characteristics were measured before and after applying mink oil to bleached hair for comparative analysis. To understand the effects of mink oil on hair texture, tensile strength, absorbance, and gloss were measured. Results: The results indicate a decrease in the tensile strength of damaged hair compared with healthy hair. Tensile strength at level 7 was achieved with high dosages of mink oil. Furthermore, the experimental group demonstrated an increase in absorbance compared with control. Compared to 0g for the control group, the absorbance values for the experimental group with mink oil dosages of 1, 2, and 3 g at level 7 decreased with the increased in mink oil dose. In terms of gloss, an increase was observed for bleached hair compared with healthy hair. At level 7, gloss decreased with the increase in mink oil dose. Conclusions: The results verified the improvement in hair texture after the application of mink oil to damaged hair. Future research should explore the effects of various oil ingredients on hair texture.

  • In spite of rapid sociocultural changes and an increase in the number of nuclear families in recent years, quite many families in Korea still have taken the extended family form where daughter-in-law provides care for the elderly parents. Even though the nature of the inter-generational relationship in Korea is reciprocal in many regards, most of the studies looked at the burden or costs of coresidence with the elderly parents while relatively little attention has been given to the positive side of the coresidence. This study is an attempt to fill this gap in the area. The purpose of this study is to examine not only the costs but also benefits of the coresidence with the elderly parents. We also explore whether there is a rural-urban differences in costs and benefits of coresidence and related factors. For the purpose, data were gathered from 876 daughters-in-law of three generational family both in rural and urban area, using structured questionnaire. The statistical methods used for data analysis were descriptive statistics, cross tables, and regression analysis with SPSS/PC+ program. The major findings of this study were as follows: Marital and economic status of the elderly parents, age, job status and filial responsibility attitude of caregiver, sibling support, and coresidence duration were the significant variables predicting the level of perceived benefits. Marital status of elderly parents, income, job status, educational level, and filial responsibility altitude of caregiver, residence region affected the level of perceived costs. Rural-urban differences are found in many aspects of coresidence experiences and related factors. Rural caregivers receive higher level of the sibling support, have more traditional final responsibility altitude and perceived less costs and more benefit than urban caregivers. There also are differences in the factors influencing the level of perceived costs and benefits between rural and urban area. Level of sibling support and final responsibility attitude have significant impact on both the perceived costs and benefits. But there are differences in terms of that perceived costs and benefits of urban caregivers are affected by job status of caregivers while those of rural caregivers are affected by educational level of caregivers and marital status of elderly. The results confirm that Korean caregivers experience both positive and negative aspects of coresidence and shows that the nature of the inter-generational relationships differ between rural and urban Korea.
