This study was conducted to study the effects of the TA Theory and the TA Program, an educational testing tool developed to improve functional communication skills for dental hygienists. The results taken from the experiment using the TA program has been verified by Examination Tool for Personnel Communication developed by Chung(2001). 44 in two experimental groups and 16 in control group took part in TA Program training sessions. The experimental Group I received TA technique training session for 12 hours per day in a period of three days and Group II for 6 hours per day in a period of two days. From this experiment, the following conclusion was obtained. The results are as follows: 1) As it can be seen from the results of the examination taken prior to the experiment, the subjects of the control group and experimental groups were homogenous in all categories including self-disclosure, awareness, evaluation and acceptance of feedback, self-expression, coping with feelings, clearness, avoidance, dominance, handling of differences, and perceived acceptance. 2) After the training of TA Program was completed on Group I and II, the examination results are as follows: Control Group (1.5158), Group I (1.8260) / Control Group (1.4684), Group II (1.9985). The results of Group I and II (1.7970 and 1.9985 respectively) therefore showed a meaningful difference. 3) From the results of the experiment it is shown that dental hygienists' communication skills improved after receiving the TA Program training. Therefore TA Program may be used as an effective tool for such purpose. 4) As it can be observed from the data, Group I and II showed difference in the degree of improvements. Therefore, there needs to be a further investigation on the effects of the difference in training period. 5) This program is not only limited to the education of dental hygienists but may be widely applied to various forms of education and teaching methods.

MRI is superior when contrasted to help the organization generate artifacts resolution, but also affect the diagnosis and create a image that can not be read. Metal is inserted into the tooth, it is necessary to often be inhibited in imaging by causing the geometric distortion due to the majority and if the difference between the magnetic susceptibility of a ferromagnetic material or paramagnetic reducing them. The purpose of this study is to conduct a metal artefact in accordance with the analysis using a diamagnetic material. The magnetic material include a wire for the orthodontic bracket and a stainless steel was used as a diamagnetic material was used copper, zinc, bismuth. Testing equipment is sequenced using 1.5T, 3T was used was measured using a SE, TSE, GE, EPI. A self-produced phantom material was used for agarose gel (10%) to a uniform signal artifacts causing materials are stainless steel were tested by placing in the center of the phantom and cover inspection of the positive cube diamagnetic material of 10mm each length.After a measurement artefact artifact zone settings area was calculated using the Wand tool After setting the Low Threshold value of 10 in the image obtained by subtracting images, including magnetic material from a pure tool phantom images using Image J. Metal artifacts occur in stainless steel metal artifact reduction was greatest in the image with the bismuth diamagnetic materials of copper and zinc is slightly reduced, but the difference in degree will not greater. The reason for this is thought to be due to hayeotgi offset most of the susceptibility in bismuth diamagnetic susceptibility of most small ferromagnetic. Most came with less artifacts in image of bismuth in both 1.5T and 3T. Sequence-specific artifact reduction was most reduced artifacts from the TSE 1.5T 3T was reduced in the most artifacts from SE. Signal-to-noise ratio was the lowest SNR is low, appears in the implant, the 1.5T was the Implant + Bi Cu and Zn showed similar results to each other. Therefore, the results of artifacts variation of diamagnetic material, magnetic susceptibility (${\chi}$) is the most this shows the reduced aspect lower than the implant artificial metal artifacts criteria in the video using low bismuth susceptibility to low material the more metal artifacts It was found that the decrease. Therefore, based on the study on the increase, the metal artifacts reduction for the whole, as well as dental prosthesis future orthodontic materials in a way that can even reduce the artifact does not appear which has been pointed out as a disadvantage of the solutions of conventional metal artifact It is considered to be material.

Adipocyte-specific secretory factor(ADSF)/resistin, an hormone, is a small cysteine-rich protein secreted from adipose tissue and ADSF/resistin has been implicated in modulating adipogenesis in human and rodents. Although the exact role of ADSF/resistin in bovine has not been identified, it may have directly or indirectly involved in adipocyte differentiation. The objective of this study was to investigate its DNA polymorphism associated with carcass traits in Korean Native Cattle(Hanwoo). To investigate DNA polymorphism in Hanwoo ADSF/resistin gene, blood samples were taken from 295 Hanwoo steers belonging to progeny testing at Hanwoo Improvement Center in Korea. Seven single nucleotide polymorphisms(SNPs) were found in intron regions but not in any other regions including promoter (1.7kb) and 4 exons. The highest frequency among SNPs was C186A(0.16/0.84) following G964A (0.156/0.884). The significant correlation(P<0.05) between the SNPs and economic traits was found on 764Ains associated with marbling but not from any other SNPs determined.  A computer simulation was also conducted to assess the efficiency of marker assisted selection(MAS) versus the conventional breeding scheme.  Results revealed that MAS was more efficient as a breeding tool compared to the conventional. In conclusion, ADSF/Resistin gene is one of candidate genes to evaluate the quality, especially marbling score, in Hanwoo.

This study aimed at analyzing the trend of re-search on pain in Korea, suggesting direction future pain research, and contributing to the use of pain interventions in nursing practice. Research studies on pain were selected from journals of medical and nursing schools, the Korean Nurse, the Korean Nurses' Academic Society Journal, the Central Journal of Medicine, the New Medical Journal, and from theses and dissertations, which were conducted between 1970 and 1994. The total number of the studies was 93. These studies were analyzed for 1) time of publication or presentation, 2) thesis for a degree or nondegree, 3) research design, 4) characteristics of subjects used in each study, 5) measurement tool, 6) types of correlated variables, 7) Korean terms for pain 8) types of nursing interventions, and 9) results of studies. The findings of the analysis can be summerized as follows : 1) The number of studies related to pain has increased rapidly since the early 1980's. The number of experimental research studies related to pain has increased chronologically, but the number of survey research studies related to pain was highest from 1981 to 1985, after that it decreased slowly. 2) The subjects in 19 studies were healthy people and, in 73 studies, patients with various illnesses. Thirty two studies were conducted with surgical patients. 3) Sixty one pain research studies were done for a thesis for a degree and 32 were nondegree research studies. 4) As measurement tools for pain, self- report pain scales were used in 54 studies and more than two tools were used in 28 studies. In the experimental studies, the trend was to use more than two tools. And in the nonexperirnental studies, the trend was to use self-report pain scales only. 5) There were 11 correlational studies. In these studies, the trend was to study anxiety, depression and variables such as intravenous infusion as related to pain.6) In the thirty six experimental studies, the effects of 16 types of nursing interventions weretested. Teaching and information, and relaxation technique were the most popular interventions for pain. 7) In eighteen methodological studies, the majority were studies testing the validity and re-liability of Dr. Lee's Korean Pain Rating Questionnaire. The following suggestions are made based on the above findings : 1) The patterns of these studies related to pain in Korea need to be compared with trends in other countries. 2) Meta - analysis should be done to analyze and integrate the results of various studies. 3) This analysis of pain research is needed to identify the present trend of pain research and to suggest the direction of future pain research, so these patterns of studies should be done in 5 to 10 year intervals. 4) More replicated pain research is needed to prove the effect of nursing interventions and more qualitative research on pain is needed to identify indepth the meaning of pain. 5) Pain researchers should make an effort to apply research result in various clinical settings and try to carry out team research with clinical nurses or with other multidiscipinary researchers.

In this study, we developed a tool for measuring user's emotions expressed while using a product in the natural and accessible environment for the design field. Also, using emotional word logging software VideoTAME, we measured a user's emotions expressed while using a product. In the testing module of VideoTAME, participants evaluate their emotional changes through playing and watching the video clips of their performing tasks in the experiment room. In the analyzing module, the researchers replay the results created by participants during the experiment and analyze the results using Microsoft Excel. In this research, we have asked users to examine their emotional changes while watching the recorded video clip of them in the experiment room performing a series of tasks using a cellular phone. In this experiment, there were no big differences in the representative emotions expressed for each characteristics of task. The reason for this can be assumed it is because of the emotional changes occurred while facing specific situations when performing a task rather than the task itself. If more data is collected and concrete statistical analysis is done, it is expected that we can clarify what effect a product's usability has on user's emotions.

To assist in selection schemes we estimate the genetic diversity of the horse breeds. Genetic diversity at 13 microsatellite loci was compared in six horse breeds : Jeju Native Horse, American Quarter, Jeju Racing Horse, Mongolian Horse, Japanese Horse and Thoroughbred. All of the equine microsatellite used in this study were amplified and were polymorphic. The expected total heterozygosity over all the populations varied between 0.669 and 0.869 and the expected heterozygosity within population range from 0.569 to 0.219 in this study. The low coefficient of gene differentiation value showed that only 0.118 of the diversity was between horses breeds. The constructed dendrogram from the genetic distance matrix showed little differentiation between horse breeds using DISPAN program. The genetic distance using 13 microsatellites ranged between 0.137 and 0.414 for the six horse breeds. These results confirm the potential use of equine microsatellite loci as a tool for genetic studies in horse populations. The genetic diversity of the six horse breeds to each other closed to their geographical distribution. Suggesting that the loci would be suitable for horse breeds parentage testing. Therefore, Microsatellite marker seems to be very useful for clarifying the evolutionary relationships of closely related populations.

The earlier KANSEI evaluation had to choose not to overlap the opposite meaning of the words, had to choose that some figures are shown step by step and had to choose be prepared things in advance. However, The Study shows a method which visualizes the imprecise evaluations of human without choosing evaluation items which are not prepared figures. The program is used the way which is entered by hand-drawing that the subjects use the way to enter their subjective feelings about the evaluations presented by using the mouse or the graphics tablet. It is possible to express imprecise things about evaluations and the method of drawing is free. The program provides that we can express our thinking by drawing and there are a few limits and the prescribed standard. The area ratio of each circle is expressed as a pie chart and the area of circle what is drawn which is counted automatically at the same time. These things are possible not only to modify a transparency, a thickness of a line, a color and the area of circle what is drawn, but also to adjust the area of circle. The conceptual model is visualized that expresses something by hand-drawing such as a circle. The conceptual model has wide range of applications such as a personnel evaluation, a suffering evaluation and product evaluation. The program currently has been testing the effective of the program's possibilities which is used with the personnel appraisal tool of the nurses themselves who work in nurse support department where the St. Marianna University School of Medicine Hospital is. And also the program is proceeding with development to visualize the conceptual model by dynamic interfaces effectively and the program is applied such as KJ method and a program is used to express the kind of the patient's pain and its level.

In recent years, rapid diagnostic tests (RDTs) have been widely used for malaria detection, primarily because of their simple operation, fast results, and straightforward interpretation. The Asan $EasyTest^{TM}$ Malaria Pf/Pan Ag is one of the most commonly used malaria RDTs in several countries, including Korea and India. In this study, we tested the diagnostic performance of this RDT in Uganda to evaluate its usefulness for field diagnosis of malaria in this country. Microscopic and PCR analyses, and the Asan $EasyTest^{TM}$ Malaria Pf/Pan Ag rapid diagnostic test, were performed on blood samples from 185 individuals with suspected malaria in several villages in Uganda. Compared to the microscopic analysis, the sensitivity of the RDT to detect malaria infection was 95.8% and 83.3% for Plasmodium falciparum and non-P. falciparum, respectively. Although the diagnostic sensitivity of the RDT decreased when parasitemia was ${\leq}500\;parasites/{\mu}l$, it showed 96.8% sensitivity (98.4% for P. falciparum and 93.8% for non-P. falciparum) in blood samples with parasitemia ${\geq}100\;parasites/{\mu}l$. The specificity of the RDT was 97.3% for P. falciparum and 97.3% for non-P. falciparum. These results collectively suggest that the accuracy of the Asan $EasyTest^{TM}$ Malaria Pf/Pan Ag makes it an effective point-of-care diagnostic tool for malaria in Uganda.

광역 조건식의 계산은 분산 프로그램의 수행을 테스트 또는 디버깅하기 위한 방법으로 활 발히 연구되고 있다. 이제까지 주로 연구된 광역조건식은 AND 또는 OR 광역 조건식 등이 있는데, 특히 AND 광역 조건식은 분산 프로그램의 동시적 조건을 표현하는데 유용하여 효율적인 검색 알고리즘이 활발히 연구되었다. 분산프로그램의 수행오류로서 공유자원의 배타적 접근조건은 가장 중요하고 일반적인 경우라 할 수 있다. 본 논문에서는 XOR 연산을 이용하여 공유자원 프로그램의 오류 검색을 위한 광역조건식을 기술하는 방식에 대해 제안하였다. XOR 연산을 이용한 광역 조건식은 연산자 중 많아야 하나의 지역조건식만이 참일 때 전체 조건식이 참이 되는데 이러한 성질은 여러 프로세스 중 한번에 하나만이 공유자원에 배타적으로 접근할 수 있는 조건을 표현하는데 매우 유용하다. n 개의 프로세스로 이루어진 분산프로그램에서 한개의 공유자원에 대한 배타적 접근 조건을 기술하기 위해서 AND로 연결된 광역조건식을 이용하면 O(n2)개의 광역 조건식이 필요한데 반해 XOR 연산으로는 하나의 조건식으로 나타낼 수 있다. 더구나 XOR 연산을 이용한 광역조건식은 최근 소개된 겹치는 구간의 개념을 활용하면 매우 간단하게 검색할 수 있다. 본 논문에서는 겹치는 구간을 찾는 검색 알고리즘을 소개하고 증명하였다.Abstract Detecting global predicates is an useful tool for debugging and testing a distributed program. Past research has considered several restricted forms of predicates, including conjunctive or disjunctive form of predicates. Especially, conjunctive predicates have attracted main attention not only because they are useful to describe simultaneous conditions in a distributed program, but also because it is possible to find algorithms to evaluate them within reasonable time bound. Detecting errors in accessing shared resources are the most popular and important constraints of distributed programs. In this paper, we introduced an exclusive OR predicates as a model of global predicates to describe shared resource conditions in distributed programs. An exclusive OR predicate holds only when at most one operand is true, which is useful to describe mutual exclusion conditions of distributed programs where only one process should be allowed to access the shared resource at a time. One exclusive OR predicate is enough to describe mutual exclusion condition of n processes with one shared resource, while it takes O(n2) conjunctive predicates. Moreover, exclusive OR condition is easily detectable using the concept of overlapping intervals introduced by Venkatesan and Dathan. An off-line algorithm for evaluating exclusive OR global predicates is presented with a correctness proof.
