Nowadays, the family system has changed from a large extended family group to a more nuclear family and the number of people who live by themselves has been increasing. Moreover, Korea is becoming an aged society, and pets are becoming more important as leave the family home. So a lot of people in Korea now consider pets as their family members due largely to the drastic change of their life style. Therefore, the rate of importing commodities for pets like cats and dogs has been increasing dramatically. In this study, in response to the growing interest in the pet industry, I have studied recent trends and types in the pets wear markets which are still in the first stage of development in Korea. In order to enhance the possibility of mass producing pets ready-made clothes for making the unit cost lower, firstly, I presented a new basic design and pattern of pets wear made up of general textile. After that, following basic purpose of pet wear, I classified decorative clothes into party wear, everyday wear and street wear and then I developed the pattern and made a pair of works for each item totaling 6 in all. I hope that the number of Korean companies which can enhance their reputation through by marketing these products in Korean as well as all around the world will increase. I believe this will be possible because by taking advantage of the easy pattern developed in this thesis. They will be able to mass produce their own high quality pets wear brand.

This paper was motivated by two gaps in the extant literature on brand portfolio planning. First, research has shown that, as the number of products connected to a brand increases, the extended product receives more favorable evaluations. However, this result was obtained by comparing two brands with different number of products while controlling the brands' breadths. Hence one may question if the above result would hold when the brand is narrow as well as broad. Second, the literature has investigated the effect of brand breadth on the perceived fit and evaluations of an extended product within a relatively limited range ("narrow vs. broad") and not considered the case of a "very broad" brand. To address these gaps, we propose two hypotheses: 1) the effects of the number of products associated with a brand on the perceived fit and evaluations of a moderately far brand extension are moderated by the brand's breadth (H1); and 2) the relationship between a brand's breadth and a moderately far extension's perceived fit and evaluations looks like an inverse-U shape (H2). Study 1 was conducted to test H1. Study 1 employed a 2 × 2 within-subjects design in which the first factor was the number of products (small (2) or large (5)), and the second factor was brand breadth (narrow or broad). We measured brand breadth as the perceived similarity among products associated with a brand. Participants provided the perceived fit and evaluations of an extended product. Study 2 was conducted to test H2 as well as to replicate Study 1 in a more general setting and with different products. It employed a 2 × 3 within-subjects design, in which the first factor was the number of products (small (2) or large (5)), and the second factor was brand breadth (narrow, broad, or very broad). The results from two experiments support both hypotheses. This paper contributes to the literature on brand extensions in two ways. First, it broadens our understanding of the effects of product number and brand breadth on extended product evaluations by considering the two factors jointly. Second, we believe this study to be the first to present evidence that brand breadth can exert an inverted U-shape effect on the perceived fit and evaluations of an extended product. The results also offer implications for marketers. First, marketers should heed the finding that adding similar products to a narrow brand does not help the brand's extension launch. Second, the finding that the relationship between brand breadth and extended product evaluations might not be linear provides practical implications. While a narrow brand should not keep launching close extensions, nor should a broad brand continue producing far extensions to broaden its breadth. A firm with a broad corporate or family brand might want to consider introducing a new brand instead of adding dissimilar products under the brand umbrella.

We are living in the 21st century, a new era of high-technology. Due to movements in population towards certain preferred areas, caused by material and technological advancement, growth has occurredn beyond the metropolis, leading to the development of the so-calleda "megalopolis." This development has changed the culture of housing, notably the characteristics of high-rise buildings, and underground facilities (such as subways and shopping centers), and has generally enlarged the scale of the facilities. Due to the increase in the number of single-family households, - notably ones including only the nuclear family, there has been a growing overpopulation problem, with apartments and urban housing developments expanding at rates beyond institutional safety regulations. In this study, we analyze the phenomenon of fire spreading in apartment buildings through actual apartment fire case studies, including that of the MunjonPonpuri apartment building. It was found that the speed at which the fire spreads is lower in apartments without than in those with an extended balcony. Based on the findings from case studies and the test results, we propose a series of safety countermeasures and responses for apartment fires.

The Web is the largest distributed information space but, the individual's capacity to read and digest contents is essentially fixed. In these Web environments, mining traversal patterns is an important problem in Web mining with a host of application domains including system design and information services. Conventional traversal pattern mining systems use the inter-pages association in sessions with only a very restricted mechanism (based on vector or matrix) for generating frequent K-Pagesets. We extend a family of novel algorithms (termed WebPR - Web Page Recommend) for mining frequent traversal patterns and then pageset to recommend. We add a WebPR(A) algorithm into a family of WebPR algorithms, and propose a new winWebPR(T) algorithm introducing a window concept on WebPR(T). Including two extended algorithms, our experimentation with two real data sets, including LadyAsiana and KBS media server site, clearly validates that our method outperforms conventional methods.

This study begins with two research interests. Firstly, there seems to be a break of research in the field of family policy in Korea which exists especially in regard to family law. Family law was originally the core of state interventions in family life, but has been neglected because of the lack of literature with comparative research methods. This shortcoming needs to be addressed. Secondly, through inquiry into the definition of family or family policy with the lens of the law, the definition of family or family policy can be correctly extended. With these two interests combined, this research tries to derive an analytical tool - maintenance community - of the law and compare some important points of the family law of Korea with those of 16 EU-countries in terms of regime classification. The method used is, firstly, to describe the subjects of family law with a focus on partnering and parenting without subjective interpretation, and secondly, to classify the countries' family-law regimes with the criteria of privacy and autonomy using cluster analysis. The results show that the countries can be classified into three clusters: Nordic (Norway and Sweden), West-Northern (Denmark, France, England, Finland, and Belgium) and Middle South (Italy, Spain, Austria, Portugal, Netherlands, Greece, Ireland, Germany, and Korea). This result can be compared to a precedent research result which showed that 21 OECD countries can be classified in three clusters according to family policy. The number of the clusters is the same as this study, but some countries belong to other clusters; for example Denmark and Finland belong to the Nordic cluster according to family policy, while they belong to the West-Northern according to family law, and Austria, Germany, and Ireland belong to the Middle-South cluster according to family law, while they belong to the Continental according to family policy. From this result we can interpret Korean family law to be in the middle range according to both criteria of privacy and autonomy like other South-European countries including some Continental countries. We can make some theoretical suggestions. The fact that both family law and family policy regimes in countries can be classified into three clusters can be interpreted to mean that there exists parallelism between family law and family policy in a broad sense. But from the fact that some countries belong to different clusters according to family law and family policy, we can say that the family policy in a country is not always consistent with family law.

The purpose of this study is to enrich our understanding of the family utilizing childcare by grandmothers and the elderly women by examining the experience of grandmothers who refused to support raising their grandchildren. The researcher focused on grandmothers who have been in charge of caring the family in the main and tried to explore the reasons for their decision not to take care of their grandchildren. For the purpose, Research participants were seven elderly women who have refused raising of their grand-children. Data were collected by in-depth interview and analyzed based on the phenomenological method. As results, it turned out that the elderly women refused caring of their grandchildren due to the burden of parenting and the rejection of an extended mother role, and the fear of family conflicts, but they felt sorry about their refusal of a request for caring support from their adult children. Second. these decisions caused various dynamics of the family members, and they were experiencing psychological difficulties. Third, elderly women perceived raising of grandchildren as a task of adult children or a problem for which the society should be accountable, and felt that the family and the society have shifted the responsibility to them. This research result confirms that a new generation of the elderly women have emerged who have different viewpoints on caregiving. It also presents a necessity to reflect the viewpoints of elderly who are mainly concerned when establishing a policy of caregiving. Based on this finding, this study also presents implications regarding support for family utilizing childcare by grandmothers and support for the elderly women.

Background: The generalized gamma distribution statistics constitute an extensive family that contains nearly all of the most commonly used distributions including the exponential, Weibull and log normal. A saturated version of the model allows covariates having effects through all the parameters of survival time distribution. Accelerated failure-time models assume that only one parameter of the distribution depends on the covariates. Methods: We fitted both the conventional GG model and the saturated form for each of its members including the Weibull and lognormal distribution; and compared them using likelihood ratios. To compare the selected parameter distribution with log logistic distribution which is a famous distribution in survival analysis that is not included in generalized gamma family, we used the Akaike information criterion (AIC; r=l(b)-2p). All models were fitted using data for 369 women age 50 years or more, diagnosed with stage IV breast cancer in BC during 1990-1999 and followed to 2010. Results: In both conventional and saturated parametric models, the lognormal was the best candidate among the GG family members; also, the lognormal fitted better than log-logistic distribution. By the conventional GG model, the variables "surgery", "radiotherapy", "hormone therapy", "erposneg" and interaction between "hormone therapy" and "erposneg" are significant. In the AFT model, we estimated the relative time for these variables. By the saturated GG model, similar significant variables are selected. Estimating the relative times in different percentiles of extended model illustrate the pattern in which the relative survival time change during the time. Conclusions: The advantage of using the generalized gamma distribution is that it facilitates estimating a model with improved fit over the standard Weibull or lognormal distributions. Alternatively, the generalized F family of distributions might be considered, of which the generalized gamma distribution is a member and also includes the commonly used log-logistic distribution.

A trematode species belonging to the genus Prosthogonimus (family: Prosthogonimidae) was collected in August, 2004 from the bursa of Fabricius of a single Little Grebe, Tachybaptus ruficollis, caught in Chuncheon, Korea. Five specimens were collected in total and fluke morphology was examined under using a light microscope. The average parasite size was 5.6 ${\times}$ 3.2 mm (length ${\times}$ width; based on 4 specimens). The genital pore was located on the anterior right margin of the oral sucker. The cirrus sac was strongly sinuous and extended beyond the intestinal bifurcation to the ventral sucker. The prepharynx was extremely short and the pharynx was small. The vitellaria consisted of 6 follicle bunches and extended from the ventral sucker to the posterior of the testes. Finally, the uterus filled the body cavity posterior to the testes. In addition, there were no heavy slings occurred anterior to the testes. Based on these morphological characteristics, the parasites were identified as P. cuneatus. The discovery of P. cuneatus within a Little Grebe constitutes a new host identification and a new geographical record. This is the first reported case of Prosthogonimus infection within wild birds in Korea.

A single specimen of Chaetodon vagabundus Linnaeus, 1758 belonging to the family Chaetodontidae was collected on September 8, 2013 in Yerae-dong, Seogwipo-si, Jeju Island, Korea. The morphological characteristics of C. vagabundus are similar to C. auriga and C. auripes in having dark vertical stripes cross the eye, but differs from C. auriga, which has high dorsal fin extended between spine and soft rays without concavity and has blotch of circle in dorsal fin, and from C. auripes which has yellow body, big of eye proportion and a black stripe along the caudal peduncle during the immature stage. C. vagabundus has eye-like black spots on dorsal fin and black vertical stripe extended from the anterior dorsal soft ray to the middle of the anal fin along the caudal peduncle. Molecular analysis results showed that our specimen perfectly matched C. vagabundus in the mitochondrial DNA COI sequences. Therefore, we use the Korean name, "Hwang-jul-na-bi-go-gi" for C. vagabundus proposed by Kim et al. (2020).

In this study, we produced kimchi with cooked Dioscorea batatas yam based on the its outstanding nutritional value, biological activity, and pharmacological action. Sliced kimchi cabbage, processed white radish kimchi (kkakdugi), and whole kimchi cabbage were prepared with 3% Dioscorea batatas, and the physicochemical and bioactivity characteristics were analyzed. In three kinds of Dioscorea batatas. The pH of the kimchi decreased and its acidity increased as the storage period was extended. The period of the maximum total viable cell count of the sliced cabbage and the processed white radish kimchi (kkakdugi) was 14 days, while the period for whole kimchi cabbage was 21 days. The period of maximum lactic acid bacteria count was 14 days for all three kinds. For physiological activities, polyphenol and flavonoid contents and DPPH elimination were highest immediately after production of the kimchi. Also, anthocyanin content increased as the storage period extended. The pH, acidity, total viable cell count, lactic acid bacteria count, and physiological activities were shown to be different according to the type of kimchi and the storage period.
