In order to improve on the stability during the storage of Han-gwa, this study measured peroxide value, AOM test of ginseng and antioxidants added to Han-gwa. 1.2% of ginseng added to Han-gwa consists of moisture (3.37%), protein(1.30%), lipids (11.54%), carbohydrate(82.45%) and ash (1.34%). The hardness of Han-gwa was 257.7 for 1.2% of ginseng added to Han-gwa and 269.8 for Han-gwa without ginseng. The expansion coefficient of Han-gwa including 1.2% of ginseng was 12.9 magnification to Bandegi, indicating that it was inversely proportioned to the amount of ginseng. The induction period of the AOM test according to the concentration of ginseng in Han-gwa was extended to $0.53{\sim}0.83$ of magnification than the test of Han-gwa without ginseng. According to changes in AOM, acid value, peroxide value and thiobarbituric acid value of Han-gwa with various packing materials, PP multilayer film packing was the most effective material for storage of Han-gwa at 30C. 1.2% of ginseng added to Han-gwa and rosemary extract in a panel test was the most effective, and using PP multilayer film packing for Han-gwa was found to be the most useful method.

This study developed HanScript, which is an educational Hangul programming language, in order to make programs easily and conveniently and applied it to the school fields. To evaluate HanScript, additionally, the researcher divided the properties of educational programming languages into easiness to read, easiness to write and easiness to debug and, based on them, compared HanScript with Visual Basic. According to the result, HanScript was expressed in Korean language style, so was easier to read and debug than Visual Basic. But it was not different from Visual Basic in debugging. Due to fewer libraries compared to Visual Basic, however, it was difficult to implement complex functions using HanScript. In addition, HanScript did not include an editor to edit source codes. Thus, if HanScript is equipped with rich libraries, detailed debugging information and an editor for source code edition, it will be a useful educational programming language.

In order to investigate processes and factors controlling the chemical and isotopic compositions of the Han River, seasonal studies were carried out. The North Han River was much lower in the concentrations of total dissolved solids (TDS), dissolved inorganic carbon (DIC) and major ions than the South Han River, but higher in $SiO_2$ concentration, $\delta$$^{34}$ $S_{so4}$ value and $^{87}$ Sr/$^{86}$ Sr ratio. This indicates that the chemical and isotopic compositions of the Han River were strongly controlled by the geology of their drainage basins: silicate rocks in the North Han River and carbonate rocks in the South Han River. The $\delta$$^{34}$ $S_{so4}$ values were relatively higher in the North Han River (5.90$\pm$1.46$\textperthousand$)) than in the South Han River (3.48$\pm$0.73$\textperthousand$). This implies that dissolved S $O_{4}$$^{2-}$ in the North Han River might be mostly derived from deposition of atmospheric sulfates, whereas in the South Han River from oxidation of sulfide minerals in the abandoned poly-metallic deposits and the coal-bearing sedimentary rocks distributed over the upstream as well as deposition of atmospheric sulfates. The $^{87}$ S $r^{86}$ Sr ratios in the North Han River were distinctly higher than those in the South Han River, reflecting water-rock interaction with different rock types.pes.

Recently, New Han-ok is in prevail because it has many good qualities as a dwelling. But the New Han-ok dwellers' needs and satisfaction ratio on their houses are not investigated yet. So, surveys on satisfaction ratio for New Han-ok were carried out to know New Han-ok's existing conditions and inhabitant's responses on New Han-ok dwellings. Followings are results. 1) Dwellers response that it is cool in summer and it is cold in winter. So, design and construction method against cold is needed for New Han-ok. 2) Window is the most picking element of New Han-ok for house improvement. 3) Window opening is main control method for cooling in summer. Warming sources in winter are various such as electricity, gas, oil, wood, etc. 4) PVC window structure and glasses were used for New Han-ok's window system as well as wooden window structure and Han-gi. 5) Interviewees are generally satisfied with New Han-ok's exterior view and inner spaces. Almost no humidifier is used. These results could be used for improvement of Han-ok and basic material for New Han-ok design.

Han-ok has a long history and cultural traditions. It has green and healthy and culture but high construction costs, thermal insulation performance of residential and vulnerable to fires and have a weakness for maintenance. However, modernized resident housing, Han-ok is required to improve in terms of environmental aspect due to its weakness for insulating and inconvenience for modem era. Also Han-Ok's building is criticized as a huge dependence on subjective building experiences. This is pointed to be the biggest problem, Han-ok has. Traditionally it does not have a scientific and specific manual for construction. In this research, process simulation was adopted to develop Han-Ok's environmental improvements. In terms of LCC (Life Cycle Cost) aspect, however, Han-Ok's environmental characteristics are examined to suggest an appropriate Han-Ok construction method. Also the result of this research would be utilized to base the information database for efficient constructing and its management in new Han-Ok constructing industry.

This study used the extensive monitoring datasets of the Korea Ministry of Environment to examine trends in dissolved organic carbon (DOC) in Han River raw water. To estimate the organic contents of water, we adopted allied parameters such as biochemical oxygen demand (BOD) and chemical oxygen demand (COD) as substitutes for DOC. Spatial and temporal analyses were performed on monthly BOD and COD data from 36 monitoring stations (14 for Main Han River, 7 for North Han River and 15 for South Han River) measured from 1989 to 2007. The results of trend analysis indicated that, on the whole, water quality according to BOD showed a downward trend at more than 67% of monitoring stations (9 for Main Han River, 6 for North Han River and 9 for South Han River). However, the water quality of COD showed an upward trend at more than 78% of monitoring stations (8 for Main Han River, 7 for North Han River and 13 for South Han River). The upward trend of COD contrary to the BOD trend indicates that there has been an increase in recalcitrant organic matter in Han River water that is not detectable by means of BOD.

Han-Thought is a philosophy unique to the native to Korean culture. From the point view of etymological analysis the word “Han” means “Large”, “High” means “Whole” Ancient Korean people planted their philosophical roots deep in what has come to be known an Han-Thought. The goal of this study was to explore “Han-Thought” for concepts and principles which may contribute to the building of a Korean nursing philosophy, ethic, paradigm, theory and eventully practice. Ontologlly, our ancient people attempted to learn what was most essential and meaningful in life Han-Thought embraces the thought of complete harmony with in wholeness. Han encompasses everything in the universe. A chracteristic of Han-Thought is that all things relate to each other in harmonic balance, not in conflict. The harmonious balance of all things excludes both disruption and confrontation, making all things into a large oneness. Thus Han-Thought applied to Holism traditionally embraced by nursing philosophy. The principles of Han-Thought emphasize the love of peace. Extreme individualism and egoism are not allowed in Han-Thought. Thus Han-Thought provide a humanistic and ethical foundation for nursing philosophy. Han-Thought is a valuable philosophy for Korean nurse to explore toward the development of the discipline in Korea.

Han-Bok presents a unique consumption ex-perience different from Western dress which is common to our clothing life. This study is intended to propose the necessity of broad-ening deepening and systematizing a research related to the social aspects of Han-bok. A questionnaire consisted of 10 statements of attitude to Han-Bok 7 statements of the evaluation of the occasional appropriateness of Han-Bok preference questions about style color harmony and decorative materials of han-Bok was developed which includes 5 opinion statement of the importance of tra-ditiona and some demographic variables. During December 1996 and January 1997 the women aged above 20 responded to it and finally 702 data was analyzed. Korean urban women have positive attitude to Han-Bok And the conceit about Han-Bok was significantly higher than the intention to wear it . The most properly evaluated occasion for wearing han-Bok was 'holdays' like Seolnal and chuseok Han-Bok was evaluated im-proper for casual wear and out wear. Factor analysis of 7 occasions determined 3 factors; traditional occasion special occasion and cas-ual occasion. It is needed to identify the ef-ficiency of Han-Bok according to each differ-ent occasion. Korean urban women preferred the style of traditional line soft color and modern har-mony. In a viewpoint of tradition they put more importance in the line of Han-Bok that they do in the color of it.

This study was conducted to investigate of water qualities in the upper and middle reaches of the Han River. For this purpose, water was sampled at Kwangjin and 1st Han-River Bridges of the Han River in Seoul and analysed from August, 1988 to September, 1989. The results are summarized as follows : 1. Water quality at 1st Han-River Bridge was more polluted than that at Kwangjin Bridge. 2. Except biological oxygen demand (BOD), turbidity, suspended solid (SS), dissolved oxygen (DO), DO saturation (DOS), ammonia nitrogen ($NH_3-N$), nitrite nitrogen ($NO_2-N$) and chloride ion ($Cl^-$) at Kwangjin and 1st Han-River Bridges were lower as compared with the previous data before redevelopment of the Han River. 3. SS, DO and pH at Kwangjin and 1st Han-River Bridges could be classified to the 1st grade in environmental water quality standard. DOS at Kwangjin Bridge was over 100% and that at 1st Han-River Bridge was below 100% in the Han River. BOD at Kwangjin Bridge could be classified to End grade and that at 1st Han-River Bridge to 3rd grade in environmental water quality standard. 4. The higher the level of water was, the lower the levels of turbidity and SS, and $NH_3-N$ was decreased with increasing water level at 1st Han-River Bridge. DO was decreased as water temperature went up but DOS was increased with DO. BOD was positively correlated with nitrite-nitrogens. 5. Turbidity and SS at the both sites and Chloride ion ($Cl^-$) at Kwangjin Bridge were increased in July and August. And DO at the both sites and $NH_3-N$ at 1st Han-River Bridge were decreased in at July and August.
