A non-traditional forage-based protocol was employed to evaluate replacement heifer growth, fertility, and economics between small frame (SF, 3.50; n = 50) and large frame (LF, 5.56; n = 50) heifers using three increasing gain growth phases. Preceding an 85 d growing-breeding period (Phase 3; P3) the heifers were managed as a common group for Phases 1 and 2 (P1 and P2). During P1, heifers grazed common fields of unharvested corn and corn residue (total digestible nutrients [TDN] 56%) with supplemental hay. For P2, heifers grazed early spring crested wheatgrass pasture (CWG; TDN 62%) that was followed by the final P3 drylot growing and breeding period (TDN 68%). Small frame heifers were lighter at the end of P1 in May and at the start of P3 breeding in August (p = 0.0002). Percent of mature body weight (BW) at the end of P1 (209 d) was 48.7% and 46.8%, respectively, for the SF and LF heifers and the percent pubertal was lower for SF than for LF heifers (18.0% vs 40.0%; p = 0.02). At breeding initiation (P3), the percentage of mature BW was 57.8 and 57.2 and the percentage pubertal was 90.0 and 96.0 (p = 0.07) for the SF and LF heifers, respectively; a 5-fold increase for SF heifers. Breeding cycle pregnancy on days 21, 42, and 63, and total percent pregnant did not differ (p>0.10). In drylot, SF heifer dry matter intake (DMI) was 20.1% less (p = 0.001) and feed cost/d was 20.3% lower (p = 0.001), but feed cost/kg of gain did not differ between SF and LF heifers (p = 0.41). Economically important live animal measurements for muscling were measured in May and at the end of the study in October. SF heifers had greater L. dorsi muscle area per unit of BW than LF heifers (p = 0.03). Small frame heifer value was lower at weaning (p = 0.005) and the non-pregnant ending heifer value was lower for SF heifers than for the LF heifers (p = 0.005). However, the total development cost was lower for SF heifers (p = 0.001) and the net cost per pregnant heifer, after accounting for the sale of non-pregnant heifers, was lower for SF heifers (p = 0.004). These data suggest that high breeding efficiency can be attained among March-April born SF and LF virgin heifers when transitioned to a more favorable May-June calving period through the strategic use of grazed and harvested forages resulting in a lower net cost per pregnant SF heifer.

Since the 1980s the development of American art furniture was embodied its concept by second-generation furniture artists affected and educated from the first generation that has implanted art furniture fundamental values. Besides, embracing inevitably needs of the new era going with the social change rather than dwell on the nature of mere handicraft era, it has evolved with economic revival in the United States, the attention and increased consumption of the public, and ongoing government-sponsored. And more recently, the American contemporary Art Furniture faces another change in the non-boundary phenomena between art and design. American art furniture since the 1980s are summarized as three major trends: Art furniture embellished with traditional hand-craft, Art furniture featured the individualistic avant-guard characteristic, Art furniture eroded the distinction between art and design. By analyzing focusing on the furniture artists and their works in contemporary art furniture deployment aspects since the 1980s, the purpose of this study can be utilized as a method to measure the forward direction, internationally competitive, creativity, and artistic value of the domestic art furniture.

The purpose of this study was to analyze the effects of parenting beliefs and maternal gatekeeping on father's parenting involvement. The participants were comprised of 459 Korean and Chinese couples with children whose ages ranged from 3 to 5 years old. The subjects completed questionnaires on the BCPRS (Beliefs Concerning the Parental Role Scale), the PRI (Parental Regulation Inventory), and the parenting involvement sub-scale of the productive father's parenting scale. The main results were as follows. First, in the father's parenting involvement sub-scale, Korean fathers showed a higher value compared to Chinese fathers. Second, Korean mothers had non-traditional parenting beliefs than the Chinese mothers had. Third, in regards to maternal gatekeeping, Chinese mothers more frequently controlled father's parenting than Korean mothers. Fourth, it was found that parenting beliefs and maternal gatekeeping in both countries had a significant influence in father's parenting involvement.

This study investigated the latent groups depending on married working women's work-family spillover. The effects of factors that determine mental health subgroups and differences were also analyzed. Mixture modeling was applied to the Korean Longitudinal Survey of Women & Families to achieve the research objectives. The major findings of this study were as follows. First, there were four subgroups that could be defined according to the work-family spillover: mid-level spillover group (mid-positive and mid-negative spillover group), high-level spillover group (high-positive and high-negative spillover group), low-level spillover group (low-positive and low-negative spillover group), and high-negative and low-positive spillover group. Second, the results of mixture regression analysis to test the effect of eco-system variables showed that age, academic background, non-traditional family value, number of children, work hours, wage income, and availability of the maternity leave were significant determinants of the latent groups. The probability of classifying in the high-negative and low-positive spillover group increased when women showed a lower academic background and wage income, higher number of children and older age, and longer work hours than others. Third, the high-level spillover group, and the high-level spillover group showed the lowest stress and the lowest depression; however, the low-level spillover group reported the highest stress and the highest depression. Implications, limitations, and future directions were discussed based on the results.

We investigated the quality of soybean paste(Doenjang) fermented by BAcillus brevis. The results obtained were as follows : soybean paste fermented by Bacillus brevis had alkaline pH and yellow ochre color. Dextrinizing activity was about 98 D.P. unit from 5th to 25th day of fermentation at 3$0^{\circ}C$ and after that day somewhat decreased . Saccharifying activity was respectively 6.1, 7.2, 6.8, 6.4 S.P. unit on 5, 15, 25 and 35th day of fermentation. Protease activity suddenly increased after 15th day of fermentation and was 250, 275, 299 unit on15, 25, 35 th day of fermentation , respectively. The most abundant free amino acid was found to be glutamic acid (561.8mg%) in soybean paste fermented by Bacillus brevis. In case of free sugar and non-volatile organic acid, fructose and oxalic acid showed highest content of 10.25mg% on 25th day and 12.20mg% on 15th day. The contents of free amino acids, free sugars, organic acids in soybean paste fermented by B.brevis were most abundant after 25 days of fermentation and this results were similar to that of traditional soybean paste. The odor of soybean paste fermented by Bacillus brevis was improved to be a nice soybean paste odor on 25th day of fermentation. However, sensory evaluation value of the taste of it decreased after 10 th day of fermentation.

The Korean jean market has become increasingly competitive due to the increased imports of global brands. This study is to understand the purchase behaviors of Korean college students toward foreign brand jeans to help Korean jean brands enhance their competitive advantages over foreign brand jeans in the Korean market. Considering perceptions of Korean consumers toward foreign brands and traditional value changes, this study proposed a research model incorporating two extended behavioral intention (BI) models, Lee's modified BI model and Ajzen's theory of planned behavior. To test the research model, a total of 240 valid data sets were collected from college students in Busan, Korea. Structural and measurement models were estimated using LISREL 8.80. Because face saving failed to attain internal validity, the research model was revised to eliminate face saving. The findings indicated that perceived behavioral control had the strongest direct influence on purchase intentions of Korean college students for foreign brand jeans. Group conformity and subjective norm had non-significant direct impacts on purchase intention, whereas group conformity had an indirect impact on purchase intention through attitude. Based on the findings, theoretical and managerial implications were provided.

This study examines the space composition and character of Elizabethan Theater base on the theory of drama and Shakespeares play in the english traditional theater. Contemporary multi purpose theater and public space is considered as a symbolic representation of the Elizabethan theaters organization and renaissance culture. In the historical theory, the Shakespeares theater was a common tool and best systeme in reflecting peoples lives. This role of theater as mass culture and new style of theater permanent design has get its value with the population increase and the urban centralization of the city and urban common sense. This study attempts to reevaluate the need of public space in modern society through a critical review of theater and its use as a open space design. Content analysis was used to discuss the topics of this study including the historical background of the theater, the relationship between Greek culture and modern design, and the role of scenery, auditorium and its impact on urban environment. The scope of the study is limited to the comparison of Elizabethan theater and space use program from the space critic and sociologist. Today the concept of theatrical space is altered with the advent of non-objects and multi media space. This study provides insights for the future implications of theatrical space in developing public space for its a new definition as cultural representation.

We have hypothesized that nuclear risk is significantly inversely related to the distance from residences to nuclear power plants and that the level of life satisfaction of residents therefore increases with the distance. We empirically explore the relationship between Ulsan citizens' life satisfaction levels and the distance between their residences and the Kori and Wolsong nuclear power plants (NPP) based on the life satisfaction approach (LSA). The dataset we used covers only Ulsan citizens from the biennial Ulsan Statistics on Citizen's Living Condition and Consciousness of 2014 and 2016. Controlling for micro-variables such as education, work satisfaction, gender, marital status, and expenditures, we found a statistically significant relationship between life satisfaction and the distance between the residences and the nuclear power plants. Nuclear negative externalities including (i) health and environmental impact, (ii) radioactive waste disposal, and (iii) the effect of severe accidents can be quantified in terms of LS units and monetary units. We were able to calculate the monetary value of NPP externalities at $277 per kilometer of distance for Kori and $280 per kilometer of distance for Wolsong at constant 2015 prices. These estimates are quite different from the traditional estimates made with the contingent valuation method, whereas they are similar to the findings of LSA studies abroad. Hence, the need to adopt the LSA in South Korea and policy implications are demonstrated.
