The purpose of the present study is to investigate the experiences of original family and social relationships in single women. Semi-structured in-depth interviews were arranged with 18 single women who met the criteria for the present research purpose. We considered only those responses of the interviewees that are directly related to their experiences of original family and social relationships, where the collected data were analyzed in three steps by methods of thematic analysis. As a result of the analysis, the experiences of original family and social relationships in single women could be grouped into six main clusters of themes which may be labeled as (1) themes centered on 'Family attachment', (2) themes centered on 'Special People' and (3) themes centered on 'Estrange relative relationship'. (4) themes centered on 'Small social life', (5) themes centered on 'Absence of a social relationshipship', (6) themes centered on 'Drive for freedom'. Among the first category of themes of 'Family attachment', we have found three sub-themes such as 'Adult Baby under parents' care', 'Confirm of single life', 'Intricate family relations'. As for the second category of themes 'Special People', three sub-themes have been found including 'I Only Love Mom.', 'Sister friend', 'My lovely nephew or niece'. And for the third category of only one theme 'Estranged relative relationship'. And for the fourth category of themes 'Small social life', there were found four sub-themes which include 'Relationship at work', 'Chat with friends', 'Keep oneself aloof from the opposite sex', 'Singles gather together'. And for the fifth category of themes 'Absence of a social relationshipship', there were found three sub-themes which include 'Alone than meeting', 'Lazism', 'Tight daily lives'. And for the final category of themes 'Drive for freedom', there were found two sub-themes which include 'Caution for attachment', 'Caution for entanglement'. In all, there are sixteen sub-themes to consider. On the basis of these results, we presented some conclusions on the experiences of original family and social relationships in single women. We also presented some implications of these results on population education and future research.

The brightness temperature from NOAA AVHRR CH 4 images was examined for the metropolitan Seoul area, the capital city of Korea, to detect the characteristics of the urban heat island for this study. Surface data from 21 meteorological stations were compared with the brightness temperatures Through computer enhancement techniques, more than 20 heat islands could be recognized in South Korea, with 1 km spatii resolution at a scale of 1: 200, 00O(Fig. 3, 4 and 6). The result of the analysis of AVHRR CH 4 images over the metropolitan Seoul area can be summerized as follows (1) The pattern of brightness temperature distribution in the metropolitan Seoul area shows a relatively strong temperature contrast between urban and rural areas. There is some indication of the warm brightness temperature zone characterrizing built-up area including CBD, densely populated residential district and industrial zone. The cool brightness temperature is asociaed with the major hills such as Bukhan-san, Nam-san and Kwanak-san or with the major water bodies such as Han-gang, and reservoirs. Although the influence of the river and reservoirs is obvious in the brightness temperauture, that of small-scaled land use features such as parks in the cities is not features such as parks in the cities is not apperent. (2) One can find a linerar relationshop between the brightenss temperature and air temperature for 10 major cities, where the difference between two variables is larger in big cities. Though the coefficient value is 0.82, one can estimate that factors of the heat islands can not be explained only by the size of the cities. The magnitude of the horizontal brightness temperature differences between urban and rural area is found to be greater than that of horizontal air temperature difference in Korea. (3) Also one can find the high heat island intensity in some smaller cities such as Changwon(won(Tu-r=9.0$^{\circ}$C) and Po-hang(Tu-r==7.1$^{\circ}$~)T. he industrial location quotient of Chang-won is the second in the country and Po-hang the third. (4) A comparision of the enhanced thermal infrared imageries in 1986 and 1989, with the map at a scale of 1:200, 000 for the meotropolitan Seoul area showes the extent of possible urbanization changes. In the last three years, the heat islands have been extended in area. zone characterrizing built-up area including (5) Although the overall data base is small, the data in Fig. 3 suggest that brightness tempeautre could ge utilized for the study on the heat island characteristics. Satellite observations are required to study and monitor the impact of urban heat island on the climate and environment on global scale. This type of remote sensing provides a meams of monitoring the growth of urban and suburban aeas and its impact on the environment.

This study was carried out with the attention that the concept of entrepreneurial orientation has been applied at various levels of CEO, employee, management, and organization as a whole. The differences between these concepts were examined by discriminant validity and convergence validity, and the causal relationship between these concepts and performance was analyzed. A total of 96 questionnaires were collected and analyzed. The results show that CEO's entrepreneurial orientation, employee's entrepreneurial orientation, manager's entrepreneurial orientation and organizational entrepreneurial orientation have convergent validity and discriminant validity, and that these variables have different effects on the firm 's innovation performance and financial performance. In the analysis of the mediating effect, when the variables of all levels were put into a single variable, the innovation performance mediates between the entrepreneurial orientation and the financial performance in all variables. However, when all variables are applied simultaneously, innovation performance has mediating effect only on the relationship between organizational entrepreneurship orientation and financial performance. This shows that there is a conceptual difference according to applied level. As a result of the analysis of the causal relationship by the application level of entrepreneurial orientation, it is found that causality is formed among the entrepreneurial orientation variables. In particular, CEO's entrepreneurial orientation influences employee's entrepreneurial orientation, manager's entrepreneurial orientation, and organization's entrepreneurial orientation, and again, employee's entrepreneurial orientation and managerial entrepreneurial orientation form a causal relationship that influences organization's entrepreneurial orientation. In the relationship between innovation performance and financial performance, CEO's entrepreneurial orientation, organization's entrepreneurial orientation, and manager's entrepreneurial orientation are influencing innovation performance, and the only variables influencing financial performance are organization's entrepreneurial orientation. In conclusion, the limitations of the study and its future direction are presented.

This study was conducted to investigate 1he quality characteristics of 1he soybean anchovy sauces added with medicinal herbs, Saururu chinensis Baill. and Houttuynia cordata Thunb. and fermented for 4 months. The total nitrogen content of 1he soybean anchovy sauce increased with the fermentation time showing the highest values in the sauce with Houttuynia cordata Thunb.. The contents of total sugar and reduced sugar were high in the order of the sauces with Houttuynia cordata Thunb.(sauce T), with Saururu chinensis Baill.(sauce B), and control. The content of salt decreased much more in the sauces with medicinal herbs. After 4 months of fermentation, pH was lowered from 5.86 to 5.27 in control, to 5.38 and 5.54 in sauce B and sauce T, respectively. Generally the total aerobic bacterial count increased until 3 months of fermentation and then decreased, and the addition of medicinal hems reduced the count especially showing apparent reduction in the sauce T. During the fermentation, total protease activity generally increased with the highest value in the sauce T. In the changes of nucleotides and their related compounds, the contents of AMP, ADP, and ATP were increased and hypoxanthine decreased during the fermentation, and IMP produced after 3 months. The soybean anchovy sauce B had 1he highest IMP and the lowest hypoxanthine after 4 months. The content of total amino acids increased showing 177.1 mg% and 134.7 mg% in the sauce B and sauce T respectively compared with 171.2 mg% of control. The contents of glutamic acid and aspartic acid were 29.2 mg% in sauce B and 34.3 mg% in sauce T, which were higher compared with 25.9 mg% of control. The fermented soybean anchovy sauce had 1he functionality of ACE inhibition with 70.5% (control), 72.5% (sauce B) and 81.6% (sauce T). In the results of sensory evaluation, the sance T scored the highest and the sauce B was preferred to control.

Removal characteristics of lead-contaminated soil at the military shooting range located in the Changwon city were studied experimentally using soil washing process. As a washing solution, hydrogen chloride (HCl) concentrations of 0.001, 0.01, 0.1 and 0.2 N were used, and soil : solution ratios were 1 : 2, 1 : 3, 1 : 4, and 1 : 5. Particle diameter of contaminated soil of 4-0.075 mm, and washing period of 5, 10, 15, 20, 30, 60, and 120 min were used as operating parameters. The optimum concentration of HCl solution was 0.1 N (56.3% of Pb removal efficiency) with 15 minutes operation period in views of economics, and the optimum soil : solution ratio was determined as 1 g : 3 mL for 69.7% of Pb removal efficiency with 0.1 N HCl and 15 minutes washing period. As washing period increased, removal efficiency was increased until 20 min of the removal efficiency of 75.3%, and then almost stable. Pb removal efficiency in soil particle diameters of 0.075 mm or more was ranged from 77.0% to 82.0%, but it was decreased to 52.8% in diameter of less than 0.075 mm. Therefore, the optimum cut-off size of the soil particle diameter was found less than 0.075 mm. Combined HCl solution and ultrasonic washing method showed better removal efficiency compared to only water or HCl washing method for particle sizes above 0.075 mm.

This study attempted to analyze the contents of Practical Arts(Technology Home Economics)Textbooks written by the 7th national curriculum in a gender equity education. The objective of this study was to suggest some improvements which should be solved in terms of gender equity in Practical Arts, Technology and Home Economics education through analyzing their teaching and learning contents. Quantitative analysis were carried out for the objective of this study, Practical Arts(Technology Home Economics)Textbooks were divided into Technology and Home Economics fields. The pictures and illustration were analyzed in terms of sexual discrimination considering the social status and role. The analysis results were as follows. First, there were few cases of sexual discrimination in the texts. On the other hand, there were some cases of sexual discrimination in the pictures and illustration. Considering the results of some studies carried out in the 6th national curriculum, many problems raised in a gender equity education standpoint in the studies were solved. However, there were some cases of sexual discrimination which should be improved in the textbooks written by the 7th national curriculum. Second, there were few cases of sexual discrimination in Practical Arts textbooks. On the contrary many problems in terms of gender equity education were found in the textbooks of Technology and Home Economics. This result may be caused by the characteristics of Technology and Home Economics. The traditional viewpoint toward Technology and Home economics Textbook needs to be changed. In other words, their textbooks have to include practical contents for the positive sense of value and right sexual roles in terms of gender equity education. The contents of Practical Arts(Technology Home economics)Textbooks should be designed considering the articulation among the subjects and grades especially in terms of gender equity education.

I the recent years, Seoul, Daejeon, Changwon, and Suncheon have started to strengthen P.R. efforts on eco-brands produced by the city and to publicize as a specialized tourist city in an attempt to change their identity and image. However, there is actually a question whether the efforts of the local governments have any direct impact on satisfaction with urban living environments and the attractions of the city. The purpose of this study was to examine the awareness of residents and visitors about the attractions of Suncheon City as an eco-city and to discuss the planning criteria for the eco-city brand building and its management. The research data was collected in Suncheon City and main results of this study are as follows. The residents and the visitors investigated were satisfied with the environmental friendliness of this city and regarded it as an eco-city. As a result of asking them why they viewed the city as an eco-city, many of the residents cited diverse green tracts of land as the reason, whereas the visitors replied they were satisfied with the state of marshy areas preserved by the city. The psychological factors related to the satisfaction of the eco-city by the residents were composed of four factors, 'cultural factor', 'urban infrastructure factor', 'ecological factor' and 'scenery factor'. The visitors were composed of five factors, 'cultural factor', 'urban infrastructure factor', 'ecological factor', 'scenery factor' and 'amenity factor'. Out of the factors, the cultural factor and the urban infrastructure factor were found to exert the largest influence on the overall satisfaction of the residents and the visitors. The ISA(Importance-Satisfaction Analysis) was made, the residents and the visitors gave top priority to 'diversity of natural attractions', 'pleasant season and weather', 'beautiful scenery', 'diversity of rare animals and plants', 'diversity of parks', 'green areas and streets', 'broad ecological area' and 'the preservation of marshy areas' among the attractions of the eco-city. They placed importance on the activation of green traffic and walking environments as well, but they weren't satisfied with the state of the two in the city. Therefore there was much room for improvement in that regard.

To investigate the water quality status of agricultural water source for greenhouse area in Gyeongnam, the surface water quality was examined six times from October in 1995 to March in 1996 at five areas in Gyeongnam. The pH values of surface water were in the range of 6.6${\sim}$9.1 pH in Kimhae and Changnyong areas were out of range in 6.0${\sim}$8.5 which was water quality standard for agriculture. The DO values of surface water were relatively high with average 10.0mg/l in Kimhae, Changnyong, Sacheon and Chinju areas except for Haman area. The BOD values of surface water exceeded water quality standard for agriculture(8.0mg/l) in three sites and one site in Haman and Sacheon, respectively. The COD values of surface water exceeded water quality standard for agriculture(8.0mg/l) in Kimhae, Changnyong and Haman. The ${NH_4}^+-N$ values in surface water of Changnyong and Haman areas were 1.21mg/l and 2.75mg/l, respectively. The average values of $NO_3\;^--N$ in surface water was appropriate for agriculture. The values of $K^+,\;Na^+,\;Mg^{2+},\;Ca^{2+},\;{PO_4}^{3-}$ and $SO_4^{2-}$ in Haman were the highest of those of the others. And Pb was below 0.1mg/l which was water quality standard for agriculture. The average values of Cu, Cd and Zn were below water quality standard for agriculture. Between COD and SS in surface water was positively correlated with r$=0.799^{{\ast}{\ast}}$. BOD in surface water was positively correlated with $NH_4\;^+-N,\;PO_4\;^{3-},\;SS,\;K^+,\;Na^+$ and $Cl^-$. Surface water pollution status of agricultural water source of greenhouse areas in Gyeongnam was in order of Chinju< Sacheon< Kimhae< Changnyong< Haman area.

Lipid contents, fatty acid compositions and free sugar contents of dried ginsengs grown for different years were studied. The lipid and free sugar were separated and quantified by silicic acid column chromatography, thin layer chromatography, gas liquid chromatography and high performance liquid chromatography. Ginseng contained $1.07{\sim}67%$ crude lipid and the hightest lipid content was shown in 3 year old root. The lipid fractions obtained by silicic acid column chromatography were mainly composed of neutral lipid$(51.35{\sim}72.30%)$. The contents of phospholipid and glycolipid in total lipids were $15.03{\sim}34.59%$ and $11.83{\sim}20.72%$, respectively. As the ginseng grew, neutral lipid content increased gradually but glycolipid decreased to the half of the one year old root. Seven components of neutral lipid separated by thin layer chromatography were identified but the other two components were not able to be identified. Triglyceride content was $14.42{\sim}23.91%$, sterol ester and unidentified material(II) were $13.58{\sim}21.26%$ and $7.13{\sim}15.83%$ respectively. The major fatty acids were linoleic acid, palmitic acid, oleic acid and linolenic acid. Linoleic acid content of total and neutral lipid was $61{\sim}65%$ palmitic acid content in phospholipid was $26{\sim}39%$ and one year old root showed the hightest contents. The fatty acid composition of neutral lipid was similar to the pattern of total lipid. Linolenic acid content of glycolipid decreased gradually. Free sugars were composed of rhamnose, fructose, glucose, sucrose, maltose and an unidentified material. The content of sucrose was $92{\sim}94%$ of total free sugars. Two year old root showed the highest sugar content and it decreased since then.
