Alkylation and allylation of arylborates give mono(ipso) and/or di(ortho and ipso) substitution products. Those factors which promote polarization or ionization of alkylating agents favor di substitution. The ${\sigma}$-type(ipso) substitution reaction of arylborates involves direct interaction of the carbon-boron bonds rather than predissociation of arylborates into aryllithiums and boranes.

Stereochemical course of the reductive decyanation of two stereoisomeric 4-t-butyl-1-phenylcyclohexanecarbonitriles 3 and 4 using solvated electron has been studied. While sodium-mediated reactions of both 3 and 4 in the presence of alcohols give the same ratio, 1.5 : 1, in favor of the thermodynamically more stable product 5 over the other one 6, the ratios obtained from the potassium-mediated process are found to be very sensitive to the kind of H-donors. When reactions are performed without H-donors, 5 is only obtained from the experiments with both stereoisomers irrespective of the metal species.

Distributions of residual stress in diffusion bonding of dissimilar materials intermetallics TiAl to steel 40Cr were simulated by FEM calculation. Results showed that destructive residual stresses presented in the minute area adjacent to bond-line of the base material with smaller coefficient of thermal expansion. Reducing bonding temperature and diminishing bonding time are in favor of the mollification of interface tresses.

This study examines how the overseas residence experience of Korean consumers influences the relationship of global fashion brand knowledge and brand choice confidence. We contrast two kinds of consumer brand knowledge, using the concepts of Alba and Hutchinson's expertise and familiarity. Considering the effect of positive affect on intuitive information processing, the present study investigated the role of positive affect in consumer brand knowledge and brand choice confidence link. The proposed model was tested with structural-equation analysis. The results show that expertise and familiarity effect the positive affect. Positive affect, in turn, influences brand choice confidence. The results indicate that the processes underlying global fashion brand knowledge and brand choice confidence link are different between the consumers with overseas residence experience for more than a year and the consumers without it. The route from expertise to positive affect has a significant impact on the consumers with overseas residence experience but not on the consumers without it; however, the route from familiarity to positive affect and the path from positive affect to brand choice confidence have a greater impact on the consumers without overseas residence experience than the consumers with it. We find that the consumers with overseas residence experience favor expertise in the process underlying global fashion brand knowledge and brand choice confidence link, whereas the consumers without it favor familiarity and affect based thought.

Logistic Regression Analysis was used to compute the odds ratio (OR) and probability of conception of Holstein dairy cows of AL-MARAIE company. Data consisted of 103,778 reproductive records collected from three farms in the central region in the Kingdom of Saudi Arabia. Records were classified according to lactation number, season of calving and milk level. At first lactation, OR of first service was 0.63 of other services and probability of pregnancy from first services was 0.39. Odds ratio increased to 1.72 at fourth lactation or probability of conception reached 0.63. The probability of conception increased from 0.39 for cows inseminated at first services to 0.75 at fifth service insemination. Odds ratio of cows calving in winter were higher than those calving in summer. Odds ratio of conception of low producing cows is about twice as likely to occur from first service as from other services. However, OR of conception of high producing cows was higher than one (probability=0.56) from first service and increased to 1.63 (probability=0.65) from third service. Odds ratio was in favor of the right uterus horn where probability of conception from first service was slightly greater than 50% in first and second lactations and less than 50% in favor of left horn in later lactations.

1. Objectives: The purpose of this study is to develop the algorithm, which can help clinicians diagnose Soyangin's symptomatology, based on the indexes for energy and fluid and those for nutrient material. 2. Methods: The items of "Donguisusebowon(東醫壽世保元)" were analysed to figure out the inevitable and sequential indexes of Soyangin's symptomatology diagnosis, in order of exterior-interior pattern differentiation, favorable-unfavorable pattern differentiation, and mild-severe-dangerous-urgent pattern differentiation. 3. Results and Conclusions: 1) 1st step: Soyangin's exterior pattern and interior pattern are differentiated in terms of heat and cold, respectively. Aversion to cold and feces are used to confirm the difference. 2) 2nd step: The existence of diarrhea is used to find out that an exterior pattern is with or without favor, while the indexes of back cold, skinniness of thigh-knee and turbid urine are used to identify an interior pattern with or without favor. 3) 3rd step: The favorably exterior-heat pattern can be either mild or severe by the indexes of stuffiness/rigidity/pain below the heart and digestion, while the unfavorably exterior-heat pattern can be either dangerous or urgent by the ones of cold-heat and specific pain. And, the favorably interior-cold pattern can be either mild or severe mainly by feces and subsidiarily by delirious speech and digestion, while the unfavorably interior-cold pattern can be either mild or severe by afternoon tidal fever and vomiting.

1. Objectives: This study is aimed to develop the algorithm, which can help clinicians diagnose Soeumin's symptomology, based on the indexes such as dry mouth, water drinking, sweat, urine, appetite, digestion, and stool, etc. 2. Methods: This research analyzes the items of "Donguisusebowon(東醫壽世保元)" to reveal the inevitable and sequential indexes of Soeumin's symptomology diagnosis, in order of exterior-interior pattern differentiation, favorable-unfavorable pattern differentiation, and mild-severe-dangerous-urgent pattern differentiation. 3. Results and Conclusions: 1) 1st step: Soeumin's exterior pattern and interior pattern are differentiated in terms of heat and cold, respectively. Stool and digestion are used to confirm the difference. 2) 2nd step: The existence of sweat is used to find out that an exterior pattern is with or without favor, while the indexes of stool, dry mouth, and generalized pain are used to identify an interior pattern with or without favor. 3) 3rd step: The favorably exterior-heat pattern can be either mild or severe by the indexes of cold-heat, stool, tidal fever, and manic raving, panting and straight looking, while the unfavorably exterior-heat pattern can be either dangerous or urgent by the ones of cold-heat, stool, and urine. And, the favorably interior-cold pattern can be either mild or severe by the indexes of stuffiness and fullness, jaundice, and edema, while the unfavorably interior-cold pattern can be either mild or severe by the ones of vexation level.

This paper investigates potential favor and intention for acceptance of digital home services through the situational inducement. The result shows that digital home services for the interactive TV, security management, family management and geographical image affect users' intention for acceptance. And it shows that favorable attitudes of the interactive TV services increase in the younger generation and internet users, favorable attitudes of the family management services increase in the thirties, and favorable attitudes of the medical management services increase in the ages of the fifties. In addition it shows that relationship between favor and intention for acceptance of digital home services affects affirmatively, which was illustrated in the coefficient value (0.661) of the R-square by the regression analysis.

The study aims to explore the impacts of types of consumer's self-construal, prices of brands, and types of discount-based sales promotion on consumers' purchase intention. For this study, a three-way mixed factor method was applied based on a formula, types of consumer's self-construal x prices of brands x types of discount-based sales promotion. The subjects were 218 females in their 20s to 30s living in seoul or Gyeonggi-do areas. For data analysis, three-way variate analysis, analysis of simple interactions and analysis of simple main impacts were conducted through use of the SPSS program. First, based on the impacts of types of consumer's self-construal, prices of brands, and types of discount-based sales promotions in the favor of consumers, there was a significant difference between higher and lower-priced brands. Second, comprehensive discounts rather than monopolistic discounts corresponded to higher favoring by consumers of interdependent self-construal. As for monopolistic discount, lower-priced products corresponded to higher favor than higher-priced ones. Third, there was a significant difference between consumers of independent self-construal and interdependent self-construal. Fourth, comprehensive discount, rather than monopolistic discount, corresponded to higher purchase intention regardless of prices of brands in the group of consumers with interdependent self-construal.

In the present study, we proposed a new numerical wave tank model to analyze the vertical tension-leg circular floating bodies, using a 2-D Navier-Stokes solver. An IBM(Immersed Boundary Method) capable of handling interactions between waves and moving structures with complex geometry on a standard regular Cartesian grid system is coupled to the VOF(Volume of Fluid) method for tracking the free surface. Present numerical results for the motions of the floating body were compared with existing experimental data as well as numerical results based on FAVOR(Fractional Area Volume Obstacle Representation) algorithm. For detailed examinations of the present model, the additional hydraulic experiments for floating motions and free surface transformations were conducted. Further, the versatility of the proposed numerical model was verified via the numerical and physical experiments for the general rectangular floating bodies. Numerical results were compared with experiments and good agreement was archived.
