To determine the distribution of feline blood types and then to estimate the risk of neonatal isoerythrolysis (NI) in non-pedigree cats, we typed blood of 482 cats of both genders and various breeds (336 domestic shorthair cat and 146 pedigree) from August 2005 through July 2007. Blood samples from Seoul and Kangwon province were typed within 5 days after collection by the simple tube method. High-titer anti-A antiserum and anti-B reagent, prepared with Triticum vulgaris lectin, were used to determine type A and type B blood, respectively. The majority of cats were type A (n = 465, 96.5%) and only 3.5% (n = 17) were type B. No type AB blood were detected. Blood type distributions among the non-pedigree and pedigree cats were similar: for non-pedigree cats, 96.4% were type A and 3.6% were type B, whereas for pedigree cats, 96.6% were type A and 3.4% were type B. All type B cats had a very strong agglutination reaction to anti-A antiserum: 8 sample for 3+ and 9 for 4+. Assuming 19% of estimated frequency for the type-B allele in domestic cats, the calculated proportion of random mating from this population at risk for developing NI was 3.4%. Based on this finding, it is strongly recommended that blood typing be performed prior to any blood transfusion or breeding to minimize blood type incompatibilities. Further comprehensive studies on the titer of naturally occurring antibodies in cat populations in Korea and the prevalence of possible NI in practice are clearly required.

This study identified domestic and foreign golf clothing norms and extended recognition and attitude on golf clothing norms expressed in a golf wear style for golfer groups in their 20s-30s. Domestic golf clothing norms were derived from a theoretical research and case study; subsequently, golfers in their 20s-30s were classified into 4 groups. In-depth interviews were conducted using a serious leisure concept to analyze attitudes and stylistic expressions. Domestic golf clothing norms derived from stipulated and implicit norms varied as a type and situation of a golf course, gender of the golfer, and domestic golfers in their 20s-30s perceived such a point. For golfers in their 20s-30s, attitudes on golf clothing norms and their stylistic expressions showed differences according to gender and leisure type. As for gender characteristics, female golfers focused on 'look prettier' in stylistic expressions through experiences with a double-standard clothing norm; however, male golfers showed strict application and observance of a clothing norm in stylistic expressions compared to female golfers. However, male golfer groups in their 20s-30s as 'casual leisure participants' and those as 'serious leisure participants' showed differences becuase the former showed a tendency to observe clothing norms from other viewpoints and evaluations and the latter showed off their abilities and careers as a means of distinction. As for characteristic of stylistic expressions according to a leisure type, golfers in their 20s-30s showed distinction as serious leisure participants through forming new and independent clothing norms. Research findings are expected to provide an opportunity to reconsidering the influence of clothing norms in young people who have a strong tendency to express clothing style as a means to pursue individuality and taste.

Catalytic combustion is the environmental-friendly technology, which has been applied to a variety of areas for industrial and domestic use in recent years. Accordingly, this study performed the development of the catalytic manufacturing technology for the high temperature and of the catalytic combustor in priority, which were aimed to be applied to a commercialized boiler. Paliadium(Pd) of a noble metal was used as a catalyst for the high temperature and supported on alumina($Al_[2}O_{3}$) and zirconia($ZrO_{2}$) in constant weight ratio. Activity of Pd catalysts is compared and analyzed in the catalytic combustion of natural gas. The ratio of $Pd/Al_{2}O_{3}=4$ was found to be better than any other weight ratios in activity and durability. The performance examination of catalysts and of combustion through the plate-type combustor made it possible to be developed the cylindrical-type combustor which has increased combustion area. Catalytic combustion boiler of 25,000 kcal/hr class was also developed, which had the optimum combustion condition at the nozzle of 5.95mm and the orifice of 21mm. This condition was determined through the performance experiments of catalytic combustion boiler to which the cylindrical-type catalytic combustor was applied.

In this study, the difference of flame stability zone for natural gases from producing districts was studied experimentally using a new type of flame stability diagram. The similarity of stable flame zone between a domestic appliance and an interchangeability test(IT) burner is also examined. As a result, the stable flame zones expressed by limits curves of flame lifting and yellow tipping show the similar results in a domestic gas range and IT burner. Furthermore, IT burner can reproduce the flash back phenomena and show the distinct difference of fuel type as the burner diameter is increased. To suggest the new type of flame stability diagram in the respect of fuel interchangeability, the air flowrate and Wobbe fuel flowrate were adopted as axis coordinates. It can be identified that the new diagram can provide the useful information on the difference of flame stability zone, heat input rate and air-fuel ratio when a fuel is altered to other fuels under the identical operating conditions. Finally, the stable flame zones for natural gas of 6 type are compared, and the detailed information to use as the interchangeability fuels of standard natural gas is provided using the new type of flame stability diagram.

The purpose of this study was to investigate the status of domestic and foreign power blogs that serve as professional source of information and to clarify the difference of the criteria for the certification and selection of power blogs. The study also analyzed the configuration of contents and the characteristic of categories of the power blogs. Eleven domestic blogs were examined, of which ten were certified as power blogs on several portal sites and one blog was operating in English. Furthermore twelve foreign blogs were examined, of which ten blogs were selected from the graded list of www.alexa.com for the Fashion Power Blog TOP 20 adopted on www.telegraph.co.uk in 2009, and two noticeable blogs were selected additionally. Data were analyzed by both theoretical and exploratory studies. The exploratory study was conducted by fourteen majors, who took interest in the blogs and were divided into two groups to look at the domestic and foreign sites, from 12 October to 12 November in 2010. The types of blogs were classified by frequency analysis of interactivity, interest provision, information provision and purchase capability. The investigators checked the type of the contents of each blog and the frequencies were used for the classification type. The analysis showed that the frequencies were in the order of information provision, followed by interest provision, and purchase capability for foreign blogs, while interest provision was followed by information provision for domestic blogs. Interactivity, interest provision, information provision and purchase capability were generally reflected in foreign blogs. Rather than interest provision and information provision, however, interactivity and purchase capability were reflected relatively weakly in domestic blogs.
