Objectives: The aim of this study is (1) to investigate the historic changes and pharmacological efficacies of Woohwangchungsim-won and (2) to discuss the necessities for Woohwangchungsim-won's clinical applications. Methods: This study was performed through (1) investigating the ancient literature records related with Woohwangchungsim-won and analyzing Woohwangchungsim-won's composition, dosage and indications, (2) searching articles about Woohwangchungsim-won on 10 major Korean web and 3 major foreign web article search engines and analyzing Woohwangchungsim-won's pharmacological efficacies and indications. Results: Woohwangchungsim-wom has been used for cerebrovascular diseases such as stroke and palpitation. Also, there are some ancient literature records of Woohwangchungsim-won's clinical applications in neuropsychiatric disorders such as depression and bipolar disorder. In addition, there have been a number of experimental studies which demonstrate Woohwangchungsim-won's neuroprotective effect on cerebral cortex and hippocampus injury. So, it is possible to infer that Woohwangchungsim-won can be used for the treatments of neuropsychiatric disorders associated with neuronal cell death in cerebral cortex and hippocampus. But there have been no or less experimental studies which demonstrate the pharmacological efficacy of Woohwangchungsim-won on such disease. Conclusion: It is necessary that further experimental studies which demonstrate Woohwangchungsim-won's pharmacological efficacy on neuropsychiatric disorders should be done and Woohwangchungsim-won's clinical applications should be expanded on the basis of those related experimental results.

In celebrating a half century history of the Korean Geographical Society, this paper is concerned about research trends of the urban geography in Korea by reviewing of 449 papers and 15 books mainly in an urban geography field. The findings are summarized as follows: (1) The development of the urban geography in Korea has several stages; \circled1 The launching stage just after 1945; \circled2 the premature stage in the 1960s; \circled3 the taking-off stage in the 1970s; \circled4 the maturing stage in the 1980s; and \circled5 culminating stage in the as of 1990s. (2) The earlier studies had a few limited research themes without major debating issues. In the 1970s, various research themes had been introduced in the urban geography. More diverse themes have been studied in urban geography after the 1980s. The major themes in the urban geography included urbanization, urban structure, urban system, urban economic structure and so on. (3) The most frequent research area for the Korean urban geographers has been the Seoul metropolitan area followed by Kyongsang-Province region. Outside Korea, the most frequent research areas are the American cities followed by the cities of Japan, Canada, and France. (4) The urban geography in Korea has played a major role in introducing the quantitative methods and techniques into geography. For example over 30.5% out of papers in urban geography has taken the quantitative techniques in the past 35 years during the 1960-1994 period. The papers inside urban geography have counted more than 60 percent from research papers in major university journals and took 34.6 percent from the papers of the Journal of Korean Geographical Society.

Helianthus annuus L. has been reported with various pharmacological activities such as antibacterial, antidiabetic, and antioxidant effects. According to recent studies, H. annuus L. is known to contain components such as phenolic compounds, flavonoids, alkaloids, sesquiterpenoids, and lignans. The seeds of H. annuus L. have been reported to contain chlorogenic acid and di-O-caffeoylquinic acid as major components. However, studies on the main components and content of leaves of H. annuus L. are still incomplete. Therefore, in this study, the contents of four major components of H. annuus L. were evaluated by simultaneous quantitative analysis with high performance liquid chromatography (HPLC)-diode array detector (DAD). The isolated four compounds Caffeoylquinic acid(CQA), 3,4-dicaffeoylquinic acid(3,4-DCQA), 3,5-dicaffeoylquinic acid(3,5-DCQA) and 4,5-dicaffeoylquinic acid(4,5-DCQA) were shown in a large linearity with a correlation coefficient (R²) of 0.99. In addition, as a result of intra-inter day analysis of four major compounds by the analysis method of this study, the accuracy of 88.46% or more and less than 112.85% and excellent precision of less than 3% were shown, the content analysis showed CQA (0.383±0.018 mg/g), 3,4-DCQA (0.282±0.017 mg/g), 3,5-DCQA (1.109±0.068 mg/g), and 4,5-DCQA (0.673±0.020 mg/g).

In analyzing time series, estimating the level or the current mean of the process plays an important role in understanding its structure and in being able to make forecasts. The studies the class of time series models where the level of the process is assumed to follow a random walk and the deviation from the level follow an ARMA process. The estimation and forecasting problem in a Bayesian framework and uses the Kalman filter to obtain forecasts based on estimates of level. In the analysis of time series, we usually make the assumption that the time series is generated by one model. However, in many situations the time series undergoes a structural change at one point in time. For example there may be a change in the distribution of random variables or in parameter values. Another example occurs when the level of the process changes abruptly at one period. In order to study such problems, the assumption that level follows a random walk process is relaxed to include a major level change at a particular point in time. The major level change is detected by examining the likelihood raio under a null hypothesis of no change and an alternative hypothesis of a major level change. The author proposes a method for estimation the size of the level change by adding one state variable to the state space model of the original Kalman filter. Detailed theoretical and numerical results are obtained for th first order autoregressive process wirth level changes.

The aim of this study is to collect and analyze clinical studies on acupuncture therapies of Post-stroke depression, and to suggest a method on study about acupuncture therapies. In this thesis, electronic searches were performed. Also, 6 major journals associated with oriental medicine in Korea were searched manually. Through searching, 27 studies were selected and analyzed. There were 24 controlled studies and 3 non-controlled studies. Treatment methods were acupuncture, electronic-acupuncture, eye-acupuncture, abdominal-acupuncture and pharmaco-puncture. The percentages of these treatment method were 59.2%, 29.6%, 3.7%, 3.7% and 3.7%, respectively. Acupuncture points such as GV20, PC6, ST36, SP6, LV3, GV24, GV26, LI14, LI11, H7, ST40, GB20, GB34 and LI15 were used. In comparison of results before and after acupuncture treatment, there were statistically significant improvement in 26 studies. Based on the results from above, the studies on acupuncture for Post-stroke depression needs to be standardized and more appropriate high-quality study models should be introduced.

The genetic diversity of Korean native chicken is important for conservation of native chicken breeds and developing economically valuable traits in Korea. In this review, various types of genetic markers using Korean native chickens were investigated, which are mtDNA variations, microsatellite markers, markers in Major Histocompatibility Complex (MHC), and single nucleotide polymorphisms (SNPs). These genetic markers are suitable for breed discrimination and diversity studies because of their high polymorphism status. Thus, the purpose of this study was to summarize the genetic markers developed in the Korean native chickens and diversity studies using these breeds. Ultimately, these markers can be used for the future studies for understanding of genetic characteristics.

The purpose of this study was to investigate the components in friendship as reported by Korean children of School age Specially, four major aspects of friendship - definition of friendship, friendship formation, friendship expectation, and friendship termination were explored. The subjects of this study consisted of 600 elementary school children in Grades 1 through 6, 50 males and 50 females at each grade level. Based on Bigelow (1977) five open - ended questions were administered. First and second graders were interviewed individually while 3rd-6th graders replied to a questionnaire in class. For content analysis, responses of each child were coded into 22 categories and each category was assigned a score from 1 to 4 according to its frequency. The data were analyzed by factor analysis. The results showed that four major aspects of friendship in Korean children of school age were found to consist of four different factors. DEFINITION OF FRIENDSHIP was found to consist of the factors; 1) reciprocity of liking vs. helping 2) global evaluation vs helping 3) sharing and 4) common activities. FRIENDSHIP FORMATION was found to consist of the factors; 1) situational effects vs complex evaluation 2) structural dimension vs common activities 3) helping and 4) staring. FRIENDSHIP EXPECTATION was found to consist of the factors; 1) mutuality 2) common activities vs. loyalty & commitment 3) exclusive - dyadic activities vs. admiration (character) and 4) interactive a1truism. FRIENDSHIP TERMINATION was found to consist of the factors; 1) physical separation vs disappointment (character) 2) conflict 3) physical separation vs. psychological dimension and 4) general altruism.

This study reviews recent shell midden studies in Korea. With more interest in biological materials, recent shell midden studies have attempted to reconstruct palaeoenvironment, and understand subsistence economy, the formation processes and function of sites and past culture. Especially, one of the major topics in prehistoric Korean shell midden studies is the transitional process from hunter-gatherer to farmer. To solve these questions related with shell middens, new sampling strategies and excavation techniques have been adopted. Analytical methods combined with scientifical technologies also have been introduced to shell middle studies. These methods indude stable isotope analyses(Oxygen isotope and Carbon and Nitrogen isotope analyses) and growth-line analysis, etc.

This study aims to investigate prejudiced descriptions of adoption and adoptive families in the major textbooks in the field of child and family welfare studies. To this end, we analyzed the compositions and contents of eleven different textbooks and found four necessary changes to recommend: first, we found it essential for authors to have a comprehensive understanding of the characteristics of the open adoption culture and adoptive families. Second, we observed the need for the revision of prejudiced terminology found in textbooks' descriptions of adoptive families - about adopters, adoptees, and adoption institutions. Third, we advise an enhancement in the understanding of adoptive families reflecting both qualitative and quantitative understandings of the open adoption culture and perspective about social prejudice against adoptive families. Finally, we advocate for the inclusion adoptive families as one of the diverse forms a family can take, not only in the curriculum of child (children's rights) studies but also in the curricula of other family-related disciplines such as family welfare and healthy family theory. Based on these four changes, we propose a new approach to authoring including a multifaceted review of the subject composition and the content of the major textbooks and revision of the overall contents of the textbooks.
