In the former half of the 18th century, For this period the literary people who led the literature of Nam'in were Sadaebu named the so-called Munoepa. There were Gang Pak(姜樸), Lee In-bok(李仁復), Lee Jung-hwan, Oh Gwang-un(吳光運), and Gang Pil-shin(姜必愼) in Munoepa(門外派). All these people as Sadaebu of Nam'in kept company with families of each other, had close relations from early childhood, and shared with same opinions in various ways like politics, culture, etc. They had intimate relationships not only in politics but also in literature, and primarily acted their part regarding the development of literary circles in the first half of the 18th century. Many individual poets who achieved the outstanding literary accomplishment appeared in the late period of Joseon Dynasty, especially in the eighteenth and nineteenth centuries. They actively made progress in their literary works with Sisa. The poets in similar positions had the Sisa to show their literary ability and check on their view about the literature. They briskly tried to express their own literary intention in activities of Sisa. Gang Pil-shin is a literary representative of the late period of Joseon Dynasty Nam'in. Through the exchange relationship of Gang Pil-shin, we can confirm certain aspects of his literary world. People who have tied up with Gang Pil-shin are largely divided into three. First, it is a literary person in Geungi Nam'in literati, typified by Backryeonsidan, Jinju Gang family, Gyeongsang Provinces area that was a place of residence. The exchanges of Gang Pil-shin were done via a poetry club. a poetry club was basically conducted mainly on relatives such as Gang Pak. However, the members of a poetry club changed according to the area where you live. Gang Pil-shin made a poetry club while coming back and forth between Seoul and Gyeongsang Provinces. This means that Gang Pil-shin also had special attention as Geungi Nam'in (近畿 南人), but also had a positive nature as Yeongnam south person. A closer look at what linguistics of Gang Pil-shin Geungi Nam'in and Yeongnam Nam'in had special characteristics late period of Joseon Dynasty It is possible to confirm the special characteristics of Seoul and the local literary exchange. For this reason, it seems that more detailed examination of the literature of Gang Pil-shin is necessary.

This paper focuses on the effects of wind pressure on transmission towers. It recommends the need for an application method to strengthen some existing towers, especially those in areas regularly affected by typhoons, and to be applied to new constructions. Some considerations taken into account were modifying existing towers exposed, which can cause significant damage to the power system and the effects of damage on third parties.

We report an unrecorded species of Corydalis sect. Corydalis (Fumariaceae), C. caudata (Lam.) Pers., that have been found in the central part of Korea. This species is easily recognized by its bearded calyx, upwardly curved spur, and multi-branched characteristics. We named it 'Soo-yeom-hyeon-ho-saek' as korean common name.

This paper checked the trend of exiting researches on Jeungsan's thought and investigated the academic problems of Daesun's thought as an basic work to form the deep academic discussions on Daesun's thought. Grouping into the scriptures of Jeungsangyo, its theses and papers, I synthesized the present state of researches. In the case of papers, I divided into three periods, before 1990, 1990s' and after 2000. Grouping into three fields, the periods, the researchers and the themes, I investigated the characteristics of the researches of Jeungsan's thought through the main scriptures, theses and papers, and reports of actual state. In conclusion, I brought up the ten problems about academic questions of Daesun's thought.

Betulinic acid and alphitolic acid, the triterpenoids of Zyziphi Fructus, were isolated with silica gel column chromatography and used as the standard substances for the analysis. The compounds were determined with HPLC and HPTLC. They were separated on reversed phase column (Nova-Pak C18) with 0.05M Na2HPO4-methanol (19:81) in HPLC and detected at 210nm. Separation on HPTLC precoated silica gel F254 plates was carried out with chloroform-methanol (6:1) and the separated compounds were reacted with p-anisaldehyde and detected at 540nm. The contents of betulinic acid and alphitolic acid in Zyziphi Fructus from four different regions in Korea were in the range of 2.9~3.8% and 3.2~3.9%, respectively.

This study was carried into execution to analyze Spatial Characteristics of Seoul Business Services Cluster in circumstance of local economic development led by knowledge-intensive business services. The analysis was performed for industrial agglomeration and companies' linkage and network. As the result, there are three business services cluster, including the largest one in Gang-Nam Gu, Seoul, and for last 10 years, there has been increasing development of business services cluster. In the meanwhile, their linkage and network have not been performed briskly. Therefore, from now on, a plan that can help companies' linkage and network performed inside of cluster to have active and international structure has to be considered in cluster policy.

In this work, torrefaction of the sewage sludge was investigated the characteristics of torrefied products and the value of as energy resource to improve energy density and to maintain consistent quality of SRF. Torrefaction was performed two important torrefaction operational parameter, temperature($150-230^{\circ}C$) and reaction time(10-60min). As raising the torrefaction temperature at long reaction times, the moisture content of torrefied products was decreased, while the heating value was increased. Moreover, increasing of the torrefaction temperature led to a increase of the content of the carbon up to 60% compare to the initial the sample, and a decrease of the content hydrogen and oxygen. Especially, Average heating value was 4,818 kcal/kg regardless of the reaction time when torrefaction was performed over $210^{\circ}C$. In addition, the fuel ration and coal band were improved after torrefaction because the O/C and the H/C ratio were decreased.

The intellectuals of the Joseon Dynasty were Yangban Sadaebu who had knowledge based on Confucianism(Neo-Confucianism), enjoyed cultural powers by expressing their knowledge in words or writing, and entered government posts to guide society with such knowledge or included some pre-officials.

This study investigated students' views in relation to a career in science as a first step towards developing science career education programs and materials. The instrument was developed through preliminary surveys. The questionnaire was sent to, administered and returned by 3608 students including 1036 primary, 1137 middle, and 1435 high school students, who were selected through stratified cluster sampling from all over the country. The results were analyzed using statistical package program. The students' image view of science, preference for science and science learning, perception of science achievement, career hope for oneself, degree of hope in getting science-related job, perception about science-related career, important factors of science career choice, and their hope for science/non-science career and the reason for their choice in the past and present were investigated. The results show that "science as an experimentation activity" was the most frequent image view of science. The preference for science and science learning was more positive than the perception of science achievement. The percentage of total students who want to have science career was 21%, and this percentage of middle school students was especially low. The most frequent answers for advantages of science career were 'useful for national development', 'possible to get new knowledge', and those for disadvantages were 'dangerous', and 'too much to study'. The most frequent reason for students' choice of a science career was 'interest in science and science learning'. Judging from these results, the basic direction for science career education should be in raising the students' preference for and interest in science learning. The positive awareness for a career in science and vision for a science job in the future should be given through a science career education and science career education proper to the students' developmental stage and characteristics is more important.
