Korean chronicles have a large amount of observational records over two thousand years. Many historical astronomical records are useful in modern times. In this study, we examined solar eclipses in Goguryeo-bongi(高句麗本紀) by using the modified(newest) nutation value and reviewed the observation area through eclipsing map. There are 11 solar eclipse records in the book. We calculated intersectional visible area with 0.6 eclipsing magnitude using the records of AD116, 124, 149, 158 and 219 and found the observational area of $N40-43^{\circ}$ and $E123-127^{\circ}$, which corresponds to the Liaodong(遼東). We also examined historical Chinese solar eclipse records and compared them with Korean eclipses.

Jang Gyung Ak thought the Yang Gi was the basis of life. This is why he said doctors should emphasize on preserving Yang Gi. Before his emphasis on Yang Gi he had to study and criticize the medical concept of HaGan, DanGye and DongWon. By criticizing and overcoming their medical concept's fallacy and limitations, he made his own medicine. JangGyungAk found the importance of YangGi in the theory of changes. In the "the Book of Changes" it is said the rising movement of YangGi is expressed by recipricals and propels heaven and earth, yin and yang to change. The phenomenon of life is also a reciprocal and is lead by YangGi, and so medicine should value Yang Gi. Because the phenomenon of life is lead by this Yang Gi, it is right to base changes of diseases and organize pattern identification. The pattern identification JangGyungAk presented as two Gang six Byun sets its base on YangGi.

In this study, we developed for processing complex features using CAM software that satisfies precision for example practice and related qualification tests suiTable for CNC training purposes. In addition, functions such as location control, speed control, and processing path generation, which are the main functions of CNC machining machines, were constructed using small equipment parts, servo motors, inverters, general purpose PCs, and commercial NC software and researched with the goal of developing low-cost education equipment. In the static accuracy inspection, the degree of machine when measuring the parallelism of the X, Y and Z axes and the vibration of the main shaft did not reach the allowable value. However, we have obtained a finished product that satisfies the CNC machine book sample shape machining, detailed functions of the position control function of the CNC machine tool, linear interpolation function, circular interpolation function, and tool offset function. In the qualification test shape processing, a shape with a degree of 1/100 mm was processed to obtain position accuracy that satisfied the tolerance.

The purpose of this study is to establish the relationship between Durand's architectural theory which provided reasonable architectural logic in the early 19th century, and architectural logic of the Modern Movement of Architecture led by avant-garde architects in the 1920's. The system of thought in architecture proposed by Durand which clarified a architectural design method(composition) is very similar to the one of the International Style(Book), which summarizes commonalities in the flow of modern architecture. This approach has something in common from the perspective of the systems of thought, despite differences in external forms and time gaps. Therefore, this study intends to examine the systems of thought in three ways. It is to examine how the two systems of thought define architecture, what is the logic of building production, and finally the value of architecture (including aesthetic values) while eliminating classical aesthetics.

The purpose of this study is to analyze the relationship between intangible asset items and company value by empirical research in the medical industry, which may enhance usefulness of the results of other empirical research on intangible asset and company value. In order to attain the purpose of this study, the stock price is taken as the independent variable and all of intangible asset items reported to a balance sheet except the development expenditures and other development expenditures, and advertisement expenses, ordinary research & development expenditures reported on the income statement are taken as the dependent variables. In the following, I carried out four meaningful results from the analysis. First, research hypothesis 1; Book value of intangible asset reported in balance sheet bears positive relationship with company value shows that development expenditures 1 variable gives positive association in a significant level while a group of \10,000-above-company shows no relationship with company value, the other group of below-\10,000-company supports a consistently significant association. All this considering, we have to keep in mind that lack of prudence may leads to wrong results when we try to analyze. Second, research hypothesis 2; Intangible asset and other intangible asset expenditures reported on the income statement gives positive effect on company value shows that R&D accounts variables give insignificance in a statistical level to all company, including entire group, \10,000-above and below consistently. These results testify that current accounting system is valid. Third, in the case of other intangible asset, it requires further examination of current KAS because statistical results show negatively significant value or insignificant value in a statistical level. That means the more intangible assets, the less company value or nothing. Last, in the case of advertisement expenditure variables of above-\10,000 and entire company shows insignificances in a statistical level consistently while below-\10,000-company shows significant result coherently. We should regard accounting information on the advertisement expenditures of \10,000-below-company with caution. The results of this study provide controversial points whether intangible asset items reported on B/S, excluding development expenditures, should be regarded as asset. To facilitate the utility of accounting information on intangible asset, it seems necessary to regard advertisement expenditures reported on I/S as asset accounts. There are further arguments on the way of dealing with intangible asset under KAS that might be considered.

The purpose of this study is to examine the effects of assertiveness training and value clarification training on nurse's conflict and conflict management mode. Fifty seven registered nurses participated in the study ; they were employed by three general hospital located in Daegu, Korea. The study employs two treatment groups. The assertiveness training group consisted of subjects who participated in 90-120 minutes sessions of assertiveness training nine times over five weeks. The other treatment group, was adiministed nine, 90-120 minutes sessions of value clarification during the same period. For the control group, nursing subjects were appointed the training after five weeks. Pre-test evaluation were administered to all subjects in three groups prior to one week of the treatment. Role conflict Inventory-general(RCI-G) and Communication Conflict Inventory-general (CCI-G) measure nurse's conflict management mode. Post-test evaluation were administered to all subjects in three groups two weeks after the last session by Role Conflict Inventory-Specific(RCI-S), Communication Conflict Inventory-Specific (CCI-S), Management Model-Specific(CMMI-S). The analysis of variance(ANOVA) and covariance(ANCOVA) on gain scores were running the SPSS program. In order to test statistical differences among mean scores of the scales obtained after treatment, multiple comparisons were carried out by Turkey method. Conclusions obtained from the results are as follows. 1. The assertiveness training and the value clarification training were effective in decreasing the nurse's role conflict. The value clarification was more effective than the assertiveness training in decreasing the nurse's role conflict. 2. Both assertiveness training and value clarification training were effective in decreasing nurse's communication conflict. There was, however, no differences between assertiveness training and value clarification training in decreasing the nurse's communication conflict. 3. The assertiveness training and the value clarification training were quite effective in compromizing and collaborating conflict management mode, to reducing the withdrawl and accomodate, force and accomodate conflict management mode to conflict. There was no difference in the effectiveness of assertiveness training and value clarification. In assessing the effects of the treatments, this study employed different measurements. It is unclear whether the measurement affected the test results. It is worth conducting a further test using the same measurements. The results of future studies can be compared with those of this study. The homogeneity of the control group and treatment group is questionable. Futher studies may employ homogeneous sample group to evaluate whether the sample characteristics bias the test results. Assertiveness training or value clarification training for nurses can be utilized in nursing intervention.

본 연구는 봉화 청암정과 석천계곡 주변을 대상으로 사료 분석과 현지 조사를 실시하고 그 결과를 토대로 과거의 식재 원형과 식생 관리방안은 도출하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, "석천지(石泉誌)"에 의하면 청암정 주변에는 소나무, 잣나무, 느티나무, 단풍나무 등의 교목류와 모란, 작약, 철쭉, 장미, 국화, 연꼿 등의 화목류가 심겨져 있었으며, 석천정사 주변에는 회양목, 대나무, 단풍나무, 복숭아나무, 다래, 작약이 식재되어 있었다. 이를 통해 청암정과 석천정사 주변은 사시가경(四時佳景)을 즐기는 완상의 목적 뿐 아니라 다양한 상징성과 의미를 가지는 식재 경관을 연출하였음을 알 수 있었다. 이들 사료에 나타난 당시의 식재 현황은 차후 청암정과 석천정사와 주변 계곡의 식생 정비와 관리시 매우 유용한 준거(準據)가 될 뿐만 아니라 더 나아가서 조선 후기의 식재 양상을 파악해 볼 수 있는 중요한 가치가 있다. 둘째, 청암정과 석천정사 주변은 "석천지"에 묘사된 대로 식재 경관을 유지해야 할 것이며, 석천계곡의 소나무 군락은 점차 축소되고 있는 실정이므로 소나무군락을 유지시키기 위해서는 외래수종과 낙엽활엽수를 제거하는 등 지속적인 관리방안이 필요할 것으로 판단된다.
