LSF scheduling policy involves the Priority Reversal which reverses the scheduling order of real-time tasks. The slack time of the task currently running isn't decreased under LSF. If the task is preempted by a task newly arrived, therefore, its slack time can become longer than those of other tasks with lower priority. This Priority Reversal can make the task with higher priority miss its deadline. In this paper, we propose a new real-time scheduling policy, Consistent_LSF guarantees consistently the scheduling order of current real-time tasks without regard to any new task. The preempted tasks are maintained in a separate stack and are scheduled earlier than the tasks with lower priority. We evaluate the performance of Consistent_LSF through experiments. The results reveal that Consistent_LSF misses deadline less than LSF across all ranges of system load.

The purpose of this study is to know what is the efficient exercise and to determine the most efficient exercise in lumbar flexibility. Therefore, in this experiment, three hip joint flexion exercises were carried out in order to see which improves the most in lumbar flexibility. The test was carried out with E university students divided in three groups, Group A: hip flexion and knee extension with supine, Group B: hip flexion and knee flexion with supine and Group C: hip flexion and knee extension with sitting- each group consisted of 13 people and everyone participated in doing the warming-up exercise, main exercise and cool-down exercise which lasted about 20 minutes and this program was done 5 times a week during the period of 6 weeks. To find out the results, we did the sit and reach test using T.K.K.4308B of Japan. We measured the results once a week and in total 8 times including initial and last measurement. The result of this study showed that each exercise method applied in each group contributed in improving lumbar flexibility. The following results show the improvement in lumbar flexibility. According to this study, Group C(T=-14.305, P=.000) had the highest degree of flexibility improvement followed by Group A(T=-10.343, P=.000) and then Group B(T=-12.012,P=.000). This study showed that the hip joint flexion exercise of these three groups have a positive effect on lumbar flexibility improvement. Furthermore, it has been proved from the study that the best among the three methods in increasing the lumbar flexibility is the exercise done by Group C.The purpose of this study is to verify the difference of effect between group and period in order to find out effect on lumbar flexibility of treatment modality(stretching, heat - stretching) and period. The subject was chosen from the mild physically normal person who range from 20 to 40 years old without any neurological problem. 본 연구는 대학생들을 대상으로 유연성 향상을 위한 여러 가지 방법 중 임상에서 주로 사용되어지는 고관절 굴곡 운동 방법을 3가지로 나누어 6주간 실시한 후 앉아 윗몸 앞으로 굽히기(Sit-and-Reach Test)로 측정 비교하여 어느 운동이 허리 유연성에 더 많은 영향을 주는지를 알아보고, 그 효과의 차이를 살펴보는데 목적이 있다. 총 39명의 대학생을 대상으로 13명씩 세 그룹으로 나누어 6주간 실험을 실시하였으며 측정방법으로는 좌 전굴 측정계를 사용하여 운동전과 운동 후의 허리 유연성 변화를 분석한 결과 다음과 같은 결론을 얻었다. 1. 각 그룹에 적용된 각각의 운동 방법 모두 피 실험자들의 유연성 향상에 기여를 한다. 2. 세 그룹의 유연성 향상의 정도가 차이가 있고 유연성 향상 정도는 C그룹, A그룹, B그룹 순으로 향상 되었다. 이상의 결론을 종합해 보면 세 그룹의 고관절 굴곡운동은 허리유연성 향상에 긍정적인 영향을 미쳤으며 그 중 그룹 C의 Hip flexion and knee extension with sitting방법이 허리 유연성을 증가시키는데 가장 큰 효과를 보였다.

The purpose of the study was to compare symptoms, medical therapies, and nursing interventions with terminal cancer patients during the last four weeks of their lives in a hospice unit and general units. For the descriptive survey study, data were collected by reviewing the charts of 243 patients who died of terminal cancer at K hospital in Seoul. The data was analyzed using Chi-square test and t-test. The study findings are summarized as follows: There were higher frequencies in physical symptoms of constipation, itching sensation, pain, sleeping disturbance, sore, and urinary difficulty for those patients in the hospice unit than those patient in general units. All emotional symptoms were recorded significantly higher for those patients in the hospice unit than those in general units. Regarding the major medical treatments, pain control was used significantly more for those patients in the hospice unit but antibiotic therapy and resuscitation were used significantly more for those patients in general units. The hospice unit provided more comprehensive nursing interventions including psychological, spiritual, and family cares as well as physiological care for terminal cancer patients. The facts showed that those patients who need hospice care in general units should be referred to the hospice unite at an appropriate time.

In this study, we investigated the effects of using concept mapping as an instructional tool on 4th graders' achievement, science learning motivation, and attitude toward science classes. T재 classes (38 students) from an elementary school were respectively assigned to a control group and a treatment group. Students were taught about "expansion of matter by heat" and "heat transfer". These topics were chosen because they require students to understand more concepts as well as relationships among them. A science learning motivation test and an attitude toward science classes test were administered as pretests. A researcher-made achievement test, the science learning motivation test, and the attitude toward science classes test were administered as posttests. The results indicated that using concept mapping in 4th-grade science classes was not significantly effective in improving students' achievement though a statistically significant positive effect was found in the subcategory of knowledge. No statistically significant effect of using concept mapping was found in the scores of the science learning motivation test and the attitude toward science classes test. Educational implications are discussed.

본 연구의 목적은 사회복지조직의 공개 채용공고가 실제채용기준을 얼마나 반영하고 있는지 파악하여 채용공고의 변화가능성을 탐색하기 위함이다. 이러한 목적을 달성하기 위해 2008년 한국사회복지사협회의 채용공고 중 210건의 조직을 표집하여 기초분석을 통해 정보내용을 파악하였고, 서울과 대전의 23개 조직의 기관장을 대상으로 1:1면접을 통해 사례연구를 진행하였다. 분석결과, 실제채용기준은 자원봉사와 실습을 통한 현장경험, 사회복지사 1급 자격증, 지원자와 조직의 비전 일치, 사회복지 마인드, 대인관계 등으로 드러났다. 그러나 이는 채용공고에 제시되지 않거나 질적인 차이를 보였다. The purpose of this study is to understand how an open employment notice has reflected the actual criterions of the recruitment, and to discover a potential for any changes. To achieve this purpose, a systematic random sample of 210 open employment notices was selected from Korea Association of Social Workers in 2008, and a descriptive analysis was conducted. The qualitative research was carried out for the case study with 23 interviewees from social welfare organizations in Seoul and Daejeon. Consequently, the actual criterions of the recruitment included the following elements: social work field practicum and volunteer work, the level one social welfare license, degree of harmony with the vision of the organization, dept of social welfare-oriented mind, and human networks. However, these criterions may not be presented in open employment notices or show that there are qualitative differences between open employment notices and the actual employment criterions.

In this paper, we propose a web resource management engine based on general DBMSs. The web resources management engine manages the meta information describing the characteristics of resourves in a target web site. The engine extracts the meta information from HTML documents in the site and stores it into a predefined database called virtual schema. We use a general-purpose DBMS for maintaining the virtual schema. For design of the virtual schema, we model each element of HTML documents as a DBMS relation, and each attribute of an element as an attribute of its corresponding DBMS relation. We also model the link information among HTML documents as another relation. In order to merge the web and database having the virtual schema, we employ some additional tags in HTML documents, which were originally proposed in the INFORMIX WebDataBlade. Our web resource management engine has the following good features: (1) it supports dynamic changes of the web resources in a site by issuing update queries on the virtual schema, (2) it provides such searches that are based on structural characteristics of HTML documents since the virtual schema keeps the necessary information, (3) it provides the standard SQL interface for users to simply search and update the web resources, and finally, (4) it is portable to any DBMSs by just extending the gateway between the web and database since it only uses the common facilities supported by general-purpose DBMSs.
