A total of 95 broccoli (Brassica oleracea L. var. italica) accessions were evaluated for the identification of desulfo-glucosinolates and their content variation in the flower head using ultra performance liquid chromatography, to select the potentially functional broccoli breeding lines. The six individual desulfo-glucosinolates, including progoitrin, glucoraphanin, sinigrin, gluconapin, glucobrassicanapin, and glucobrassicin, were commonly identified, based on the chromatogram peak comparison with those of the nine individual glucosinolate standards. The total glucosinolate contents varied from 4.2 to $29.0{\mu}mol{\cdot}g^{-1}$ DW and the glucoraphanin (1.6 to $13.9{\mu}mol{\cdot}g^{-1}$ DW) was confirmed as a major constituent in the total glucosinolate profile among the six identified individual glucosinolate species, whereas the progoitrin, which was only detected in 13 accessions, showed accession-specific variation and negative correlation with glucoraphanin content. It was also revealed that the four major glucosinolates, such as glucobrassicanapin, glucoraphanin, glucobrassicin, and gluconapin, affected major content variation and showed higher positive inter-correlation. These results might be used for the selection of potential breeding materials as functional broccoli germplasm through the further evaluation on the stability and reproducibility of glucosinolate profile depending on environmental factors or cultural managements using the selected accessions.

Broadcast-seeded rice in submerged paddy frequently lodge in the field. In general, the causes of lodging in rice cultivation differ with different cultural methods. This study was conducted to investigate the causes of lodging in broadcast-seeded rice (BSR) and hand-transplanted rice (HTR) under four nitrogen (N) levels. Lodging in BSR was mainly a root lodging due to shallow root distribution, while that in HTR showed a bending type owing to deep rooting system. At the upper soil layer (0-5cm from the surface of ground) the root distribution of BSR (65.2%) was much larger than that of HTR (51.6%), whereas at the 5-10cm soil layer the root distribution of BSR (18.5%) was much smaller than that of HTR (28.0%). The depth of buried culm base was much shallower in BSR (1.2cm) than in HTR (4.0cm). The plant height, fresh weight, lodging index, culm diameter and thickness in HTR were much greater than those in BSR, and the breaking strength of lower internode was similar in the two cultivation methods indicating that HTR would have more lodging causes than BSR. In spite of . the more advantages to lodging resistance in BSR it severely lodged in the field. The main lodging-inducing factors of BSR were the shallow root distribution and shallow depth of buried culm base. Besides these, the higher ratio of gravity center of culm was an important factor. This result suggested that for the fundamental prevention of lodging in BSR, an ideotype of rice plant with ' a deep-rooted behavior ' should be developed.

The Pohang Chilpori is the area with abundant petroglyphs in Korea. The form of the shield, female sex organs, and yut board on the outcrops or float rocks which are composed of the rhyolitic rock are engraved on Chilpori and Shinheungri Petroglyphs. The rhyolitic rock is composed of the phenocryst and groundmass with quartz and feldspar. The rock surface shows mostly yellowish brown color and the rock surface is very irregular by serious weathering, and illite and kaolinite, a kind of the clay minerals, are produced. Deterioration aspects are mainly of surface exfoliation, grain peel-off, damages, scribbling. Chilpori Petroglyph (1) plane has been eroded by running water, in (2) plane has been abrased is on the rock surface, in (3) plane shows surface exfoliation and the various part of the rock surface in plane (4) has become the soil. The corrasion and black phenomenon of the Shinheungri Petroglyph (1) plane was formed by running water, and surface exfoliation and scribbling in plane (2) is serious. Deterioration factors are geomorphologic states, plants, rock of weak to weathering, and artificial influence such as a scribbling and a forest fire. For conservation of the these petroglyphs, study for rock surface conservation and the arrangement of around petroglyphs and construction of water wall are necessary.

The purpose of this study is to investigate communication efficacy of advertisement text through audience responses. This study approached qualitatively to KT&G TV commercials. The research proceeded as follows: First, as background theory, studies on audience focusing advertisement criticism and the interpretation of advertising texts were reviewed. Secondly, the characteristics of the audiences of the advertisements, analyzed through in-depth individual interviews as well as group interviews, were incorporated into a broad theme and then divided into different dimensions. Finally, the audiences' decoding code and critic reponses in reading ambiguous advertising texts, and the interrelationship between strategic ambiguity were discussed under a unified model. The major findings of this study are as follows: In interpreting the ambiguous advertising texts, the audiences use various decoding codes such as language, visuals, technology and rhetoric, and various critic responses such as linguistic, macroscopic, schematic, non-verbal and socio-cultural factors, in quite comprehensive manner. Also, it was shown that audiences make use of different decoding strategies in terms of their recognition, reliability, emotional attitude, and behavior. It can therefore be concluded that the strategic ambiguity has its limit in explaining its effectiveness in the entire dimensions of recognition, emotional attitude, and behavior, in the sense that the strategic ambiguity is most effective in recognition while it invokes more negativity in the behavioral dimension. Finally, this empirical study, focusing on qualitative analyses, may have its limit as well; however, deeper statistic-qualitative studies in the future could compensate for it.

Marine oil spill accidents are occurring continuously due to the marine transportation of the oil. While building a preventive system for oil spill is uttermost necessary, we also need to have a systematic response system to handle the oil spills that inevitably occur. So far, studies have focused on the environmentally sensitive resources affected by oil spills. However, there is a need to conduct research to evaluate the damage to the socially and economically sensitive resources that make up the life of local residents. This study represents the process of building an analytical framework for the assessment of socioeconomic resources affected by marine oil spills. While it is important to provide a scheme for identification and indexation of socially and economically sensitive resources that is compatible with Korea's situations, using existing data for identifying socio-economically sensitive resources might also be meaningful. However, to allow accurate analysis for better evaluation, we need to select more applicable data among the various indicators. In this research, we have reviewed many existing case studies of sensitive resources, studies of the variables that have been used for indexing sensitive resources, and various factors considered in SIA (Social Impact Assessment). Based on the findings, we classify socio-economically sensitive resources into marine products acquisition, population, land usage, administrative area, and cultural heritage and tourist region.

The roles of public libraries have been diverse not only provision of information but also provision of cultural programs. According to this trend, the spatial composition of public libraries have been also changed to reflect the diverse roles. This study is conducted to explore the spatial characteristics in public libraries with two objectives: 1) to suggest spatial types in public libraries based on their physical characteristics, and 2) to explore the relationships between the spatial types and users' perception. To accomplish these objectives, we adopted observation and questionnaire survey as research methods. Consequently, three spatial types of public libraries are identified based on an investigation of several public libraries: divided, partially integrated, and integrated. Then, several statistical analyses, including one-way analysis of variance (ANOVA), are conducted with the questionnaire survey data. The results from the statical analyses show that there are significant differences in users' perceptions and behaviors between the spatial types. That is, the spatial type influences user's perceptions. This study is meaningful in terms of its first attempt to explore the relationships between spatial factors in libraries and users' perceptions. Based on this, it is suggested that libraries should consider their spatial structures for developing user's positive perception on the libraries.

Background: Family values of a married woman may be related to her own depressive mood. Since depressive mood of a married woman is likely to exert a negative influence, in terms of mental health, on her, her family members, and the whole society's, it may be very important to explore the relationship between family values in married women and their depressive mood. Methods: In this study, we analyzed nationally representative 5,818 married women aged 20 years or older from the 4th panel data of 2012 Korean Longitudinal Survey of Women and Families. As for variables of interest, we constructed three family values variables: family-oriented view of marriage, individualistic view of marriage, and traditional view of marital roles. Then we employed multivariate logistic regression analyses to explore the relationship between family values and depressive mood, adjusting for family and socio-demographic factors. Results: In total, 804 married women (18.4%) had experienced depressive mood. All of the three family values variables were significant in their relationships with depressive mood. The women categorized as 'very weak' in family-oriented view of marriage were more likely to experience depressive mood than the women categorized as 'very strong' (odds ratio [OR], 1.98; 95% confidence interval [CI], 1.53-2.55). By contrast, the women categorized as 'very weak' in individualistic view of marriage (OR, 0.43; 95% CI, 0.33-0.55) and in traditional view of marital roles (OR, 0.68; 95% CI, 0.51-0.92) were less likely to experience depressive mood than their respective counterpart women categorized as 'very strong.' Conclusion: In Korea, married women's values towards marriage itself and roles between wives and husbands had significant associations with their depressive mood. This suggests that in order to improve mental health in married women, we need to take social and cultural dimensions into consideration along with public health interventions.

The METRO-K is a model for a radiological dose assessment due to a radioactive contamination in the Korean urban environment. The model has been taken part in the Urban Remediation Working Group within the IAEA's (International Atomic Energy Agency) EMRAS (${\mathbf{\underline{E}}}nvironmental$ ${\mathbf{\underline{M}}}odeling$ for ${\mathbf{\underline{RA}}}diation$ ${\mathbf{\underline{S}}}afety$) program. The Working Croup designed for the intercomparison of radioactive contamination to be resulted from the explosion of a radiological dispersal device in a hypothetical city. This paper dealt intensively with a part among a lot of predictive results which had been performed in the EMRAS program. The predictive results of three different models (METRO-K, RESRAD-RDD, CPHR) were submitted to the Working Group. The gap of predictive results was due to the difference of mathemathical modeling approaches, parameter values, understanding of assessors. Even if final results (for example, dose rates from contamintaed surfaces which might affect to a receptor) are similar, the understanding on the contribution of contaminated surfaces showed a great difference. Judging from the authors, it is due to the lack of understanding and information on radioactive terrors as well as the social and cultural gaps which assessors have been experienced. Therefore, it can be known that the experience of assessors and their subjective judgements might be important factors to get reliable results. If the acquisition of a little additional information is possible, it was identified that the METRO-K might be a useful tool for decision support against contamination resulting from radioactive terrors by improving the existing model.

This study sought to figure out women's functional status after childbirth under the Sanhujori. Functioal status was defined as the women's readiness to assume infant care responsibilities and resume her usual activities including household, social and community, self-care and occupational activity. A convenience sample of 211 women who are in the postpartal period of the range from 1 week to 3 months above and residing in Seoul. Korea was studied from January, 1997 to December, 1998 for two years. Mean age of respondents was 29.9 years and mean of the present postpartal period was 7.5 weeks. The present postpartal period was of 5-8 weeks 26.5%, 3-4weeks 26.1%, 9-12 week 23.7% and below 2 weeks 7.1%, 32.7% of women had a job and the mean period of return to job was 2.76 weeks. During Sanhujori the non professional care giver was family members from women's maiden home 73.5% and only 2% of husband. The period women needed for the recovery from now was 5.39 weeks and it means that women need 12.9weeks for recovery after childbirth. For the present subjective health status after childbirth, bad was 20.2%, good 18.3 and average 61.5% and for the recovery status, completely recovered 29.5%, slightly 61.8% and rarely 8.7%. The mean of functional status at the 7.5weeks was baby care activity 3.65, household 2.57, self-care 2.46, occupational 2.44 and social 1.53 in rank. Except baby care the functional status was generally low or very low. The related factors to the functional status were the period and subjective evaluation of Sanhujori women experienced, the present period of postpartum, and subjective feeling of recovery. This result strongly reflects the effects of Sanhujori culture and Sanhujori per se on women's postpartal life including functional status and reconfirmed the relationship between health status and the experience of Sanhujori after delivery as the previous findings from various study showed. It provides a challenge to the professional care givers to research further on the effects of Sanhujori on the health status, health recovery after abortion or delivery from the various aspects through the cross-sectional and longitudinal research for the refinement of the reality of Sanhujori not only as cultural phenomenon but as an inseparable factor influencing in women's postpartal healthy adaptation and for the appropriateness of intervention and quality of care for desirable health outcome.

By comparing to Chinese American banks, this research shows the uniqueness of Korean American banks. This article argues that instead of the cultural attributes and/or informal financial institutions, formal financial institutions, such as the ethnic banks studied here, are responsible for the business success of Asians abroad. However, ethnic banks have different development trajectories depending on their respective ethnic communities. Korean American banks are notably different from Chinese American banks in terms of growth, profitability, and banking strategies. Although both ethnic banks exercise relationship banking strategies in their loan portfolios, their deposit compositions are very different and cause significant differences in financial performance. The focus on business loans and high rates of non-interest deposits allow for higher growth rates in Korean American banks. Therefore, relationship banking does not adequately explain the differences of ethnic banks. This research attempts to understand the underlying factors in choosing banking strategies by mainly focusing on the unique examples found in Korean and Chinese immigrant societies. For Chinese Americans, the heterogeneity of their population composition and foreign influence dominate their bank structures. On the other hand, Korean American homogeneity and business orientation are distinctly different. The influence of Korean capital is not significant when compared to overseas Chinese capital.
