Using 378,086 lactation records on dairy cattle, environmental factors influencing acetone and ${\beta}$-hydroxybutyrate acid contents in raw milk which are used as ketosis diagnosis indicator traits were analyzed in this experiment. Significance testing was conducted on farm, lactation stage, parity, milking time and month of age by traits. The results of this experiment indicated that there was a highly significant (p < 0.01) difference in all factors and lactation stage was the most significant factor. Linear regression coefficients of month of age on daily milk yields and acetone and ${\beta}$-hydroxybutyrate acid contents were all positive, while their quadratic linear regression coefficients were negative. Least square means for milk yield at second lactation stage (36~65 days) was 19.06kg which was higher than that of late lactation stage by 6.51kg. Least square means for acetone and ${\beta}$-hydroxybutyrate acid contents at the first lactation stage (5~35 days) were highest (0.1929mM/L and 0.0742mM/L, respectively), and there was a trend that they decreased as the milking progressed, but increased slightly at the late stage of milking. However, least square means for acetone and ${\beta}$-hydroxybutyrate acid contents at the first parity were 0.1414mM/L and 0.0522mM/L, respectively, which were higher than the average milk yield after the second parity. Least square means for acetone and ${\beta}$-hydroxybutyrate acid contents of PM milk yield (0.1372mM/L and 0.0534mM/L, respectively) were higher than those of AM milk yield collectively.

Simulated acid rain (pH 4.0, pH 2.0) containing sulfuric and nitric acid in the ratio of 60:40 (chemical equivalent basis) diluted with underground water, and underground water (pH 6.5) as control were treated on potted Pines koraiensis seeds during the growing season (May 1 to August 31) in 1985. The regime of artificial acid rain, in terms of spray frequency and amount per plot, was simulated on the basis of climatological data averaged for 30 years of records. The seedling growth, contents of chemical substances in needles and chemical properties of the tested soil were compared among the various pH levels of acid rain on October 31, 1985. Following results were obtained. 1. With decreasing pH levels of acid rain, S and $K_2O$ contents in leaf tissue were increased, but MgO and $P_2O_5$ contents were decreased. 2. Soil pH was dropped, and exchangeable aluminum content in the tested soil was dramatically increased as the pH levels of acid rain decreased. 3. Exchangeable calcium, magnesium, potassium contents, and base saturation degree of the soil were significantly decreased with decreasing pH levels of acid rain. 4. Sulfate concentrations in the soil were significantly increased as rain pH decreased, but total nitrogen and available phosphate contents were not influenced by acid rain.

The purpose of this study is to examine the implications of religious activities to longevity in a perspective of religious people in the ancient near east. The major sources of the study are the records of Adad-Guppi in the Neo-Babylonian Empire, prayers of Daniel in the Old Testament and records of Anna in the New Testament. The research method is a synchronic method based on final forms of the texts. Adad-Guppi lived for 104 years with temple-centered lives, fasting-like dedication, prayer and mission for the nation. Daniel fasted and prayed for the return of Jewish nation, and restoration of the city and the temple in Jerusalem, resulting in longevity of late eighties in the court of Babylon. Anna lived for more than 100 years old with her life mission for the messiah in spite of limitations of her times as an old widow. The implications of religious activities with temple-centered lives, fasting, prayer, and mission for the ages are understood to be beneficial to longevity in a perspective of the ancient near east.

Someone said Chongkukjang(淸麴醬) might be a Jang(醬) that made it possible to eat quickly at the time of war, and it is called Jonkukjang(戰國醬), or it might have been learned from the Qing Dynasty, and it was also called Chongkukjang(淸國醬) or Jonsijang(煎?醬). It is not true. Even more they say the first appearance of Chongkukjang in the Korean ancient documents is in "Jeungbosallimgyeongje(增補山林經濟)" of the 1700s. Other argument is that Chongkukjang is also known as the Three Kingdoms since it was in the records of 'Shi(?)' which means Meju and chongkukjang written in "The Chronicles of the Three States(三國史記)". It is not clear whether Chongkukjang was introduced from the Qing Dynasty (1600s) or from the Three kingdom period. In this article, the history of Chongkukjang was studied through the records of ancient documents. There was a Chongkukjang(?) in Goguryeo and Silla era. Chongkukjang was called as Jyonkuk(젼국), Chyonkuk(쳔국), Chyongkuk(?국), and it was written as '?' as the Chinese character. Chongkukjang began to be perceived as Jang such as Doenjang and Gochujang at some time, and it was used as Jonsijang, Jonkukjang, but now it was unified as Chongkukjang(淸國醬). The meaning of '?' also means Chongkukjang until the 1500s, and after 1600, it happened to be it's meaning is changed to Meju and Doenjang. There is no evidence that Chongkukjang has history of war or food related to the Qing Dynasty. Chongkukjang has more than 2200 years of history, but since it was there before it recorded, it had a history of thousands of years earlier than this.

This study was conducted to serve as a basis for education by identifying the correlation of college admission type, college-life satisfaction and academic achievement of radiologic science students. Data were collected from 2 universities and 2 colleges located in Gyeonggi Provice, North Chungcheong Province, North Gyeongsang Province. A total of 371 questionnaires were collected, 363 of which were included in this study. The results showed that there were no differences in academic achievement according to the type of college admission. It could be able to interpret that since department of radiologic science is popular, students with high academic records applies the department of radiologic science and there are less deviation of academic records among students. A correlation analysis of academic achievement showed learning attitude is a statistically valid factor. Learning attitudes can be changed by exposure to the environment. This will require a variety of program development for improving learning attitudes. In addition, academic achievement of radiologic science students is associated with license acquisition. It need to be made together research on determinants and development of learning method to improve the learning attitude.

The research aims to analyze current university information disclosure services in the perspectives of both university records management and services and to recommend ways to improve the current university information disclosure systems and services. The research collects and analyzes various raw data such as laws, guidelines, and manuals of university information disclosure services and the portal site of 'Higher Education in Korea' also known as 'dae-hak-al-ri-mi', and data on each homepage of 40 cooperative universities selected as the research sample. At the result, the research found some limits in the current operation of university information disclosure services: first, the information posted on the university disclosure information system is mostly focused on administrative information rather than information related to research or education within universities. Second, there are the high rate of error and frequent modification in the information posted on the disclosure information system. Third, the menus on both the information disclosure system and homepages of each cooperative university are useless or contents of the menus are empty. The research suggests some solutions to improve these problems: it is required to make up the current legal systems for university information disclosure services and to cooperate all organizations and universities related to university information disclosure services within the united system and rule. Also, it is crucial to attach the metadata of the disclosed information when to post the information to the university disclosure information systems. Finally, it is necessary for each university to employ archivists not only to develop qualified university records to maintain the unique roles and value of universities but also to disclose reliable and authentic information to users and manage the university information disclosure systems effectively and efficiently.

In this study, some changes of soil characteristics in a field were analyzed to investigate the effect of heavy rainfall during rainy season. The heavy rainfalls were often induced geohazards like landslides. To do this, the reaching rainfall in the ground surface was investigated according to a condition of vegetation, and the change of soil characteristics induced by infiltrating rainfall was analyzed. The study site is a natural terrain located in Daedeok Science Complex. This site has same geology and soil condition whereas it has different vegetable condition. The rainfall records during the rainy season of 2006 and 2007 were selected. The rainfall records are based on the measuring date from Daejeon Regional Meteorological Administration adjacent to the study site. Also, the rainfall records according to the condition of vegetation were measured using rainfall measuring device made by ourselves. The soil tests were carried out about soil specimen sampled before and after rainfall, and then the change of soil characteristics related to rainfall and vegetation were analyzed. As the result, the density of vegetation was influenced by reaching rainfall quantity in the ground surface, and its influence intensity was decreased with rainfall intensity and rainfall duration. Also, it shows that degree of saturations, water contents, liquidities and shear resistances are directly influenced by heavy rainfalls.

Objectives : The purpose of this study was to analyze dental records performed through a dental hygiene process and provide basic data on clinical training education for dental hygienists. Methods : The dental hygiene records of 440 senior dental hygiene students in Y University from March 2005 to September 2008, were examined. The needs of the clients confirmed by the dental hygiene diagnosis was based on Human Need Theory. The client's needs and the number of visits were analyzed according to the general characteristics(gender, age). The contents of the dental hygiene implementation performed according to the needs were divided into dental hygiene care and oral health education. The dental hygiene evaluation was classified into 'Met of Goal', 'Partially Met of Goal', and 'Unmet of Goal' according to the dental hygiene diagnosis. Data analysis was performed for the Frequency statistics and a Fisher's exact test using SPSS 12.0K for Windows. Results : 1. The clients were mostly aged in their 20's(307 clients). 2. The dental hygiene care usually performed was 'Scaling' and 'Recommendation to visit a dental clinic', and the education performed was 'How to brush teeth'. The implementation result from the need to Freedom of Stress was as simple as 'Be careful when treating' and 'Explanation of medical treatment and tools'. 3. The dental hygiene evaluation showed a higher met rate in the field of education than in that of the dental hygiene care. The reason for unmet the goal was 'Lack of the client's efforts and they didn't visit dental clinic'. Conclusions : The search for a range of clients for dental hygiene process should be made through effective connections between the local community institutions and schools. It was suggested that they should be strength the practical exercises for clients suffering dental anxiety and stress in dental treatments. In addition, education and attempts to motivate the clients should be performed according to their characteristics.

This article examines the academic world of Professor Sa jin-sil. This article is not a detailed and rigorous assessment of Prof. Sa's work. During my directly or indirectly meeting with Prof. Sa jin-sil, the writing was based on my experiences. This is why the theme of "participatory observation records" is attached. I was aware that this writing would become a customary and formal funeral speech. Because I thought Prof. Sa also did not want formal and customary writing. The initiation of the participatory observational records that I describe was the literature study of Prof. Sa. What I am about to say in the title of the table of "Known Performance and to Revalue." There I summarized my thoughts on what Prof. Sa contributed to the research of the literature study on traditional performance and my opinion of the justice of the assessment of her contributions. I have not recommitted again about contributions or achievements that have already been widely recognized. What I noticed here was what was to be revalued. I once again stressed the achievements that were not properly evaluated despite their importance and significance. In the ensuing discussion, I looked at Prof. Sa's entirely different academic side. I call the passage "an unexpected result against prejudice." The subjects covered were Prof. Sa's field-contextual studies. Prof. Sa is often referred to as a dramatical history or a traditional performing arts scholar who studies literature. Such an idea is so common that it is easy to overlook field-contextual research results, not literature-based. But I think this is prejudice. That is why the title of the table of contents has the words 'unexpected' and 'prejudice'. Here I actively emphasized and evaluated Professor Sa's achievements in field-contextual studies.

This study aims to implement a model for developing participatory labor archives for shipbuilding labor archives in young-do, Busan, and to find possibilities of building digital labor archives as participatory ones. The methodology of locality documentation has been applied, and locality archives accepting participation of people with experiences from shipbuilding industry have been examined. Omeka was applied because it is an open-source software and provides additional functions which support various user participations and web-publishing. Following the the model, firstly, a preliminary investigation was conducted and research of participatory agents and records was proceeded. Secondly, it collected and described information of the agents and records by institutions with records and provenance. Thirdly, it developed archival contents specific to events, persons and workplaces in association with archival information. For the follow-up study, plugins were installed and tested to apply for further experiment with participation.
