  • This study was initiated to investigate thatch accumulation in several turfgrasses grown under two soil systems. The 45 centimeter deep USGA system was constructed with rootzone, intermediate and drainage layers. The mono-layer system, however, was made with only a 30cm rootzone layer. Turfgrasses used in the study were comprised of 3 varieties from Korean lawngrass of Warm-Season Grass(WSG) and 3 blends and 3 mixtures from Cool-Season Grass(CSG). A total of 9 turfgrass treatments were replicated three times in RCBD in both systems. Cultural practices for the research plot followed a typical maintenance program for highly managed turf. Treatment differences for thatch accumulation were observed among the turfgrasses in both soil systems. Thatch under the USGA system was 9% greater than under the mono-layer system due to its more favorable conditions for turf growth. Higher thatch depth was found with Korean lawngrass, 34~87% in the USGA system and 16~75% in the mono-layer system when compared with CSG. Among WSG, the Joongji variety was the highest in thatch layer under both the USGA and mono-layer systems. Kentucky bluegrass(KB) was the greatest among CSG, since it is a rhizomatous-type in growth habit, resulting in faster production of organic matter over bunch-type of tall fescue and perennial ryegrass. Proper depth in the thatch layer was known to be beneficial by enhancing the resiliency and wear tolerance of the turf in athletic fields. Thus, KB was considered to be a very excellent turfgrass in terms of turf quality, environmental performance, physical properties and soccer player safety. However, disadvantages such as poor water-holding properties, more inclined to injury from environmental stresses and severe diseases and insect injury were also expected where thatch was excessively accumulated. Therefore, these results demonstrate that more frequent measures for controlling thatch such as vertical mowing, topdressing or coring should be employed for soccer fields with Korean lawngrass and KB over other turfgrasses.

  • The purpose of this study was to improve the culturability of 'IR 36', a indica type rice cultivar using DNA marker associated with the ability of plant regeneration in anther and seed culture. The culturability of 6 rice cultivars and 2 indica/japonica lines ('MGRI 036', 'MGRI 079') were investigated in anther and seed culture. The culturability of 3 japonica rice cultivars were much higher than tongil and indica rice cultivars, and 'MGRI 036' and 'MGRI 079' has high culturability with 20% regenerability, also. 34 $BC_2F_4$ 4 lines were selected by marker screening using RZ400 among 90 $BC_2F_4$ lines derived from a cross between 'MGRI 079' and 'IR 36'. The frequency of callus formation of 10 $BC_2F_4$ lines were higher than 'IR 36' in anther culture among selected 34 $BC_2F_4$ lines. The ability of plant regeneration of 10 lines were higher than 'IR 36' in the seed culture among selected 34 $BC_2F_4$ lines. A promising line, $BC_2F_4$-28, was selected to have better culturability in the anther and seed culture among selected 34 $BC_2F_4$ lines. The heading date and grain shape of the $BC_2F_4$-28 was similar to 'IR 36'. Using the RZ400 DNA marker associated with the culturability will be useful method for improving of indica rice culticvar's culturability in rice breeding program.

  • Purpose: The purpose of this study is to identified patterns and trend of studies and to analyzed the nursing research related to the mother-child interaction in Korea and to improve direction of nursing research in mother-child interaction in Korea. Method: The research studies related to the mother-child interaction were selected from the Korean Nurses Academic Society Journal, and from dissertation, which were conducted between 1961 and 2002 with the consideration of the condition and the cultural specialty of Korea. The total numbers of the studies were 34. These studies were classified according to 1)time of publication or presentation, 2)research design, 3)type of interaction objects, 4)measurement tool, and 5)chief content of studies. Ressult: 1) Until 1984, there was no research studies related to mother-child interaction. The number of studies on the mother-child interaction on the mother-child interaction has been increased rapidly after 1985. The mother-child interaction studies were 13(38.2%) from the doctoral dissertation, 4(11.8%) from the Master's theses and 17(50%) other papers were published in academic journals. 2) Experimental studies of research design was used in these research studies was 13(38.2%). Descriptive studies was 8(23.6%), correlational studies was 4(11.8%) and comparative studies was 4(11.8%). Qualitative study was just one(2.9%) and literature review was 4(11.8%). Especially experimental studies has been increased. 3) Participants of these studies were mother and infant 29(85.5%), father and infant 2(5.9%), mother and fetus 2(5.9%) and nurse and infant 1(2.9%) 4) Utilization of instruments as follows: 13 studies used Walker et al(1986)'s MIPIS (Mother-Infant Play Interaction Scale), 6 studies used Barnard(1978)'s NCAFS (Nursing Child Assessment Feeding Scale), 4 studies used NCATS(Nursing child Assessment Teaching Scale) for assessing mother-infant interaction. 3 studies used Stainton(1981)'s Parent-Infant Interaction Scale. Choi(1987), Kim(1999) and Kim and Son(1997) used measurement tool researcher made which was modified from NCATS (Nursing child Assessment Teaching Scale) and AMIS(Assessment of Mother-Infant Sensitivity Scale). Other tools used to survey influencing factors of interaction. 5) Content of the research studies were classified 3 different types, such as ① studies about the mother-child interactions' pattern, ② studies about influencing factors of the mother-child interaction, ③ studies about effect of nursing intervention program to improve the mother-child interaction. Conclusion: Therefore we make following suggestions which are made based on the above research analysis : 1) In the future research studies need to compare with other area of discipline in mother-child interaction. 2) More attention and in depth research is needed to validate in terms of research design and statistical data analysis. 3) It is important to develop the instruments which is culturally acceptable in Korea society. 4) The results of correlational studies and experimental studies needs to the integrated by meta analysis.

  • Social enterprises that are solving pressing global issues and providing services such as micro-finance, affordable housing, appropriate technology and education for the 'bottom of the pyramid' as well as cultural and community-related businesses that improve the 'quality of life' within a society are the target of impact investments. Among them, a capital financing is one of the most important factor in founding and fostering of social enterprise. However, the capital market for social enterprises in South Korea are not yet sufficiently developed. The Britain and U.S.A. attempted to solve the social problem by the introduction of the social innovation credit model, for example, social impact bonds(SIB), Big Society Capital, DBLIF, and ACCION International, which are considered as an innovative new financing instrument for social program. Instruments are being attempted for the first time in Britain and America. This study have two purposes. The first purpose is abstracting the institutional mechanism for introduction of impact investment such as SIB and DBLIF case in Britain and U.S.A.. Second, analyzing type and mix of policy instrument on impact investment from the perspective of policy instrument.

  • To analyze the effectiveness of horticultural therapy reported in research papers, a meta-analysis was carried out with 108 of 377 Korean and overseas research papers on horticultural therapy from 1985 to February 2009 (196 Korean dissertations, 113 Korean journal articles, 5 overseas dissertations, and 63 overseas journal articles). The results revealed a large effect size of 0.71. The effectiveness according to the type, age and number of participants were also analyzed. The therapy was most effective in children, and it was more beneficial for children with special needs and elderly people affected by dementia than for the typical population. The greatest effect was found with group sizes of five people or less, and when carried out by researchers from departments related to horticultural therapy than by researchers from unrelated fields of study. The most effective horticultural therapy programs involved floral decorations; and participants who took part in 21 to 30 sessions or at least 31 sessions benefited the most. Among the main effects of short-term horticultural therapy are cognitive, social, physical and emotional; the greatest effect was observed in the physical domain.

  • This study aims to analyze the changes in school/corporate authorities participation after overseas training in Germany and Switzerland. According to this study, the satisfaction with program contents and help for the operation of apprenticeship education was very high. Even though the satisfaction with each type of apprenticeship education institutes did not show differences in accordance with participants' age, there were statistically significant differences in the satisfaction in accordance with work area and position, so that it would be necessary to reflect the results of analysis on the selection of institutes to visit in the future. Regarding the changes in the perception of operation of apprenticeship school in accordance with school/corporate authorities' participation in overseas training, school authorities' perception of the whole areas was improved after training than before training like understanding, planning, practice, and evaluation of apprenticeship education while corporate authorities' perception was not. As corporate authorities also understood the necessity of overseas training for the operation of apprenticeship education, however, in order to increase the effects of overseas training in the future, it would be necessary to provide lots of information to help the understanding of apprenticeship education through preliminary training or regular council and council of each project group. Because of the huge differences in socio-cultural conditions in the practice of apprenticeship education between Korea and two countries such as Germany and Switzerland, it would be needed to operate overseas training that could draw the improvement measures within the system of Korea instead of simple comparative analysis.

  • The purpose of this study ahead of the aging society in Korea to prevent problems of the elderly aged new addiction Internet Addiction and identify factors affecting the quantitative increase and qualitative improvement beyond that aims to promote. To this end, residents in Seoul over the age of 60's targets, local welfare, cultural centers, senior centers and other research in the area through one-on-one interviews were conducted the survey. Findings The average degree of Internet addiction elderly 36.16 points (SD = 10.02) and the distribution of at least 20 points to 65 points, respectively. Factors affecting the degree of Internet addiction as a computer time (β = .248, p <.001), mon allowance (β = .180, p <.01), age (β = .139, p <.01) and social support (β = .087, p <.05), self-efficacy (β = - .078, p <.05), most used location (β = - .116, p <.05), degree of family relationship (β = - .147, p <.01), housing type (β = - .153, p <.01), were of the order, this factor was 17.6% of the variance. In other words, the more computer time, the higher the age, the more mon allowance, housing is not self, the lower the degree of family relationship, the house is not a place most used, lower self-efficacy, social support is high As increasing the degree of Internet addiction was thought to be the two predictor variables. Survey results to target the elderly through the Internet addiction group psychotherapy program implementation, and production and distribution of manuals related to Internet use and addiction-related factors, according to the case-by-case Case management services are tailored to be done, and the Internet in general for seniors potential risks related to use in training and preventive services for the elderly will need to be made.

  • Rural life improvement programs (RLIPs) have been implemented with a central goal of improving the quality of rural life and promoting rural welfare and cultural life. However, different factors may influence the effect of rural life improvement programs on rural communities or households. This study aimed to investigate the determinants of perceived effects of RLIPs on quality of life of rural women in South Korea. We used a mixed research design to generate data for this study. We collected survey data from 311 rural women who participated in the RLIPs and also conducted a focus group discussion. We analyzed the quantitative data using descriptive statistics and hierarchical regression to identify the variables that predicted effects of RLIPs on quality of life of rural women. Our study finds that age, type of residence in the community, leadership experience, level of education, community satisfaction and community participation influenced respondents' perceived effects of RLIPs. The results imply that the benefits of a development intervention could not be uniformly reaped by residents of a community.

  • Go bears significant meanings in terms of cultural and entertaining functions in Asia Eastern such as China and Japan. Beyond the mere entertaining level, it produces philosophical and mythic discourse as well. As a part of effort to seek an identity of Korean traditional garden culture, this study traced back to find meanings of rock-go-board and taste for the arts which ancestors pursued in playing Go game, through analysis and interpretation of correlation among origin of place name, nearby scenery, carved letters and vicinal handed-down place name. At the same time, their position, shape and location types were interpreted through comprehensive research and analysis of stone-go-boards including rock-go-board. Particularly, it focused on the rock names related to Sundoism(仙道) Ideal world, fixed due to a connection between traces of Sundoism and places in a folk etymology. Series of this work is to highlight features of the immortal sceneries, one of traditional landscaping ideals, by understanding place identity and scenic features of where the rock-go-boards are carved. These works are expected to become foundation for promotion and preservation of the traditional landscaping remains. The contents of this study could be summarized as follows; First, round stone and square board for round sky and angled land, black and white color for harmony of yin and yang and 361paths for rotating sky are symbols projecting order of universe. Sayings of Gyuljungjirak(橘中之樂), Sangsansaho(商山四皓), Nangagosa(爛柯故事) formed based on the idea of eternity stand for union of sky and sun. It indicates Go game which matches life and nature spatiotemporally and elegant taste for arts pursuing beauty and leisure. Second, the stone-go-boards found through this research, are 18 in total. 3 of those(16.1%), Gangjin Weolnamsaji, Yangsan Sohanjeong and Banryongdae ones were classified into movable Seokguk and 15(83.9%) including Banghakdong were turned out to be non-movable rock-go-boards carved on natural rocks. Third, upon the result of materializing location types of rock-go-boards, 15 are mountain stream type(83.9%) and 3 are rock peak type(16.1%). Among those, the one at Sobaeksam Sinseonbong is located at the highest place(1,389m). Considering the fact that all of 15 rock-go-boards were found at mountainous areas lower than 500m, it is recognizable that where the Go-boards are the parts of the living space, not far from secular world. Fourth, there are 7 Sunjang(巡將) Go with 17 Hwajeoms(花點), which is a traditional Go board type, but their existences, numbers and shapes of Hwajeom appear variously. Based on the fact, it is recognizable that culture of making go-board had been handed down for an extended period of time. Among the studied rock-goboards, the biggest one was Muju Sasunam[$80(82)cm{\times}80(82)cm$] while the smallest one was Yangsan Sohandjeong Seokguk ($40cm{\times}40cm$). The dimension of length and breadth are both $49cm{\times}48cm$ on average, which is realistic size for actual Go play. Fifth, the biggest bed rock, an under-masonry with carved Go-board on it, was one in Muju Sasunam[$8.7m{\times}7.5m(65.25m^2)$], followed by ones in Hoengseong Chuiseok[$7.8m{\times}6.3m(49.14m^2$] and Goisan Sungukam[$6.7m{\times}5.7m(37.14m^2)$]. Meanwhile, the smallest rock-go-board was turned out to be one in Seoul Banghak-dong. There was no consistency in directions of the Go-boards, which gives a hint that geographical features and sceneries of locations were considered first and then these were carved toward an optimal direction corresponding to the conditions. Sixth, rock-go-boards were all located in valleys and peaks of mountains with breathtaking scenery. It seems closely related to ancestors' taste for arts. Particularly, rock-go-boards are apprehended as facilities related to taste for arts for having leisure in many mountains and big streams under the idea of union of sky and human as a primitive communal line. Go became a medium of hermits, which is a traditional image of Go-game, and symbol of amusement and entertainment with the idea that Go is an essence of scholar culture enabling to reach the Tao of turning back to nature. Seventh, the further ancient time going back to, the more dreamlike the Go-boards are. It is an evident for that Sundoism, which used to be unacceptable once, became more visible and realistic. Considering the high relation between rock-go-boards and Sundoism relevant names such as Sundoism peak in Danyang Sobaeksan, 4 hermits rock in Muju and Sundoism hermit rock in Jangsu, Sundoism hermit rocks and rock-go-boards are sceneries and observation spots to express a communication of worship and longing for Sundoism. Eighth, 3 elements-physical environment such as location type of the rock-go-boards, human activities concentrated on 8 sceneries and Dongcheongugok(洞天九曲) setup and relevancy to Confucian scholars, as well as 'Sangsansaho' motif and 'Nangagosa' symbolic meaning were used as interpretation tools in order to judge the place identity. Upon the result, spatial investigation is required with respect to Sunyoodongcheon(仙遊洞天) concept based on enjoyment to unify with the nature rather than Dongcheongugok concept of neo-Confucian, for Dongcheon and Dongmoon(洞門) motives carved around the rock-go-boards. Generally, places where mountain stream type rock-go-boards were formed were hermit spaces of Confucianism or Sundoism. They are considered to have compromised one other with the change of times. Particularly, in the rock-go-board at the mountain peak, sublimity-oriented advent of Sundoism is considered as a significant factor to control place identity. Ninth, including where the rock-go-boards were established, the vicinal areas are well-known as parts of Dongcheongugok and Palkyung(八景) mostly. In addition, many of Sundoism relevant expressions were discovered even in the neighboring carvings written by scholars and nobility, which means sophisticated taste based on longing for Sundoism world played a significant role in making go-board. The rock-go-board is an integration of cultural phenomena naturally managed by seclusion of scholars in the Joseon Dynasty as well as remains and essence of Korean traditional landscaping. Some rock-go-boards out of 17 discovered in South Korea, including ones in Sobaeksan Sinsunbong, Banghak-dong, Chungju Gongili, Muju Sasunam, Yangsan Eogokdong Banryongdae Seokguk, are damaged such as cracks in rocks or fainted lines by hardships of time and hand stains. Worse yet, in case of Eunyang Bangudae Jipcheongjeong board, it is very difficult to identify the shape due to being buried. Rock-go-boards are valuable sculptures in terms of cultural asset and artwork since they reflect ancestors' love for nature and longing for Sundoism world. Therefore, they should be maintained properly with right preservation method. Not only rock-boards itself but also peripheral places are excellent cultural heritages and crucial cultural assets. In addition, vicinal sceneries of where rock-goboards and pavilion spots are the representative remains of embracing prototype of Korean traditional landscaping and major parts of cultural properties.

  • The student's attitude toward science is generally influenced by their teachers. Therefore, teachers' positive attitudes toward science and science teaching play an important role to change the student's attitude toward science. The purpose of this survey is to investigate the status on attitudes toward science and science teaching among the secondary school science teachers in Korea. The attitudes were surveyed by the questionnaire which was developed by Sung-Jae Pak. The instrument is designed to use Likert type scale and is composed of two kinds of scale: one is the attitudes toward science scale (the AT scale) and the other is the attitudes toward science teaching scale (the AT Kale), which contains 24 questions respectively. Each of them has 6 sub-level areas. The six areas of attitude toward science are as follow: The goals and values, process and method of science, knowledge and the view of nature, social and cultural aspects, scientist and a career in science, the preferences and willingness. The six areas of attitude toward science teaching are as follow: The goals and values, process and method of science teaching, the content and structure, social and cultural aspects, science educator and a career in science teaching, satisfaction and willingness. From 152 teachers' responses, the tendency of total as well as each area and the contrast of their backgrounds at the level of 5% significance were analyzed by SPSS computer program. Some results and conclusion of the study are as follow: 1. The overall attitude of the measured secondary school science teachers shows a positive trend tendency. Also total positive attitude toward science teaching are slightly higher than that of science, which support the fact that the teachers are not scientists but they are directly involved in teaching of science. 2. The attitudes toward science are moderately correlated to the attitudes toward science teaching (r=0.52). 3. The areas of knowledge, nature-view and tile area of social aspects of science show a very negative tendency. Also the two areas are not correlated to some other areal at the level at 5% significance. 4. Female science teachers exhibit just a little more positive attitudes than those of male teachers in science teaching. 5. The science teachers who wanted to have a profession of scholar or educator exhibit a little more positive attitudes than others in science and total attitudes (AS+AT). 6. The more the science teachers have "intellectual delights" the more their attitudes toward science and science teaching are positive. 7. At the level of 5% significance, there are differences which college they graduated from, but there are no differences in multiple comparison at 10% level. 8. The differences in their background dose not appear in such as age; teaching career; academic career; deny the superstition; their onlook for the scientist or educator when they were freshmen; major the basic science; opinions about the U.F.O. and the origin of life. 9. The responses of certain individual statement are quite different from the overall tendencies, which strongly suggest the de1ailed analysis and deeper study. For the continuing study, it is recommendable to revile the measuring tools with the theoretical study for the better validity and reliability, and investigate the status of the attitudes toward science and science teaching among the science teachers with sufficient samples.
