This study examines the impact of consumer knowledge and familiarity with private label brands (PLBs) on perceptions and preferences toward PLBs and patronage intentions; in addition, it examines the incremental effects of a department store image over consumer knowledge and familiarity with perceptions, preferences, and patronage intentions. This study focused on midscale department store PLBs of apparel products and middle age consumers between the ages of 30 and 50 who are the main consumer group of private label brands of apparel products. A structured questionnaire was developed and data were collected from a convenience sample of 257 female consumers between the ages of 35 and 54, living in the Southeastern United States. A factor analysis identified the dimensions of department store image constructs; in addition, a hierarchical regression and multiple regression analyses examined the hypotheses. Consumer knowledge and familiarity with PLBs at department stores is recognized as a major determinant to shape consumer perceptions of and preferences for the PLBs as well as patronage intentions. The present study reveals the significant incremental effect of a store image on consumer preferences, perceptions, and patronage intentions beyond that explained by consumer knowledge and familiarity about PLBs. The study reveals that, among four store image constructs, the store atmosphere and store service factors had significant positive effects on consumer perceptions of PLBs. Store service and atmospheric aspects also affect consumer patronage intentions toward PLBs. The price factor shows a significant and positive influence on the preference consumers have for PLBs, but not on perceptions and patronage intentions. This study has practical implications for department store executives and managers on how to allocate resources in order to increase positive consumer perceptions toward PLBs, preferences over other brands, and patronage intentions of PLBs at a store as well as how to create effective store environments to promote PLBs.

$Ca^{2+}-signals$ in endothelial cells are determined by release from intracellular stores and entry through the plasma membrane. In this review, the nature of $Ca^{2+}$ entry and mechanisms of its control are reviewed. The following ion channels play a pivotal role in regulation of the driving force for $Ca^{2+}$ entry: an inwardly rectifying $K^+$ channel, identified as Kir2.1, a big-conductance, $Ca^{2+}-activated$ $K^+$ channel (hslo) and at least two $Cl^-$ channels (a volume regulated $Cl^-$ channel, VRAC, and a $Ca^{2+}$ activated $Cl^-$ channel, CaCC). At least two different types of $Ca^{2+}$-entry channels exist: 1. A typical CRAC-like, highly selective $Ca^{2+}$ channel is described. Current density for this $Ca^{2+}$ entry is approximately 0.1pA/pF at 0 mV and thus 10 times smaller than in Jurkat or mast cells. 2. Another entry pathway for $Ca^{2+}$ entry is a more non-selective channel, which might be regulated by intracellular $Ca^{2+}$. Although detected in endothelial cells, the functional role of trp1,3,4 as possible channel proteins is unclear. Expression of trp3 in macrovascular endothelial cells from bovine pulmonary artery induced non-selective cation channels which are probably not store operated or failed to induce any current. Several features as well as a characterisation of $Ca^{2+}$-oscillations in endothelial cells is also presented.

The purpose of this study is to investigate influences of perceived price dimensions and store attributes on store choice behavior. Three major retail formats, department store, discount store, and internet shopping mall in retail industry were compared with respect to store attributes and intention to purchase fashion products. Data were obtained from 427 consumers aged 25-49 years old. The results were as follows. (1) Multidimensional aspects of the price construct were identified: price-quality schema, prestige sensitivity, price mavenism, value consciousness, price consciousness, and sales proneness. (2) Store attributes included product assortment, quality per price (Q/P), service, and symbolic image in general. However, store attribute factors of three retail formats consisted of slightly different items. Department stores presented the highest level of mean scores on product quality, customer service, and symbolic images, while internet mall exhibited highest on product variety, information comparison, and quality per price. (3) Respondents presented high level of intention to purchase fashion products at internet mall, department store, and discount store in that order. (4) Purchase intention at department store was predicted by Q/P, service, symbolic image, prestige sensitivity, product assortment, clothing consumption, and age in order. Purchase intention at discount store was influenced by assortment & Q/P, symbolic image, clothing consumption, and sales proneness, whereas internet mall was predicted by product assortment, Q/P, service, price mavenism, and price-quality schema.

In a myocyte freshly isolated from rabbit cerebral artery, the characteristics of $Ca^{2+}$ release by histamine or caffeine were studied by microspectrofluorimetry using a $Ca^{2+}-binding$ fluorescent dye, fura-2. Histamine (5 ${\mu}M$) or caffeine (10 mM) induced a phasic rise of cytoplasmic free $Ca^{2+}$ concentration $([Ca^{2+}]_C)$ which could occur repetitively with extracellular $Ca^{2+}$ but only once or twice in $Ca^{2+}-free$ bathing solution. Also, the treatment with inhibitor of sarcoplasmic reticulum $Ca^{2+}-ATPase$ suppressed the rise of $[Ca^{2+}]_C$ by histamine or caffeine. In $Ca^{2+}-free$ bathing solution, short application of caffeine in advance markedly attenuated the effect of histamine, and vice versa. In normal $Ca^{2+}-containing$ solution with ryanodine (2 ${\mu}M$), the caffeine-induced rise of $[Ca^{2+}]_C$ occurred only once and in this condition, the response to histamine was also suppressed. On the other hand, in the presence of ryanodine, histamine could induce repetitive rise of $[Ca^{2+}]_C$ while the amplitude of peak rise became stepwisely decreased and eventually disappeared. These results suggest that two different $Ca^{2+}-release$ mechanisms (caffeine-sensitive and histamine-sensitive) are present in rabbit cerebral artery myocyte and the corresponding pools overlap each other functionally. Increase of $[Ca^{2+}]_C$ by histamine seems to partially activate ryanodine receptors present in caffeine-sensitive pool.

Carbon dioxide is one of the major driving forces causing climate changes, and many countries have been trying to reduce carbon dioxide emissions from various sources. Soil stores more carbon dioxide(two to three times) amounts than atmosphere indicating that soil organic carbon emission management are a pivotal issue. In this study, we developed a Soil Organic Carbon(SOC) storage estimation model to predict SOC storage amounts in soils. Also, SOC storage values were assessed based on the carbon emission price provided from Republic Of Korea(ROK). Here, the SOC model calculated the soil hydraulic properties based on the soil physical and chemical information. Base on the calculated the soil hydraulic properties and the soil physical chemical information, SOC storage amounts were estimated. In validation, the estimated SOC storage amounts were 486,696 tons($3.526kg/m^2$) in Jindo-gun and shown similarly compared to the previous literature review. These results supported the robustness of our SOC model in estimating SOC storage amounts. The total SOC storage amount in ROK was 305 Mt, and the SOC amount at Gyeongsangbuk-do were relatively higher than other regions. But the SOC storage amount(per unit) was highest in Jeju island indicating that volcanic ashes might influence on the relatively higher SOC amount. Based on these results, the SOC storage value was shown as 8.4 trillion won in ROK. Even though our SOC model was not fully validated due to lacks of measured SOC data, our approach can be useful for policy-makers in reducing soil organic carbon emission from soils against climate changes.

Purpose: Patients with brain damage suffer from limitations in performing the activities of daily living (ADL) because of their motor function and visual perception impairment. The aim of this study was to help improve the motor function and visual perception ability of patients with brain damage by providing them with virtual reality-based contents. The usability results of the patients and specialists group were also evaluated. Methods: The ADL contents consisted of living room, kitchen, veranda, and convenience store, similar to a real home environment, and these were organized by a rehabilitation specialist (e.g., neurologist, physiotherapist, and occupational therapist). The contents consisted of tasks, such as turning on the living room lights, organizing the drawers, organizing the kitchen, watering the plants on the veranda, and buying products at convenience stores. To evaluate the usability of the virtual reality-based visual cognitive rehabilitation service, general elderly subjects (n=11), stroke patients (n=7), stroke patients with visual impairment (n=4), and rehabilitation specialists (n=11) were selected. The questionnaires were distributed to the subjects who were using the service, and the subjective satisfaction of individual users was obtained as data. The data were analyzed using SPSS 21.0 software. The general characteristics of the users and the evaluation scores of the experts were analyzed using descriptive statistics. Results: The usability test result of this study showed that the mean value of the questionnaire related to content understanding and difficulty was high, between 4-5 points. Conclusion: The virtual reality rehabilitation service of this study is an efficient service that can improve the function, interest, and motivation of stroke patients.

The purpose of this study is to investigate the sin satisfaction and fitness of Chinese women for Korean-made women's suits. The study methodology was questionnaire survey and the subjects were randomly chosen, 20 to 49-year-old female shoppers at department stores in Beijing, China. The data analyses were performed with SPSS 12.0 through descriptive analysis, t-test, and crosstab analysis. The findings were as follows. Chinese women assessed both the fit satisfaction and fit suitability levels of Korean-made women's suits available in China to be higher than that of Chinese-made women's suits. Paticularly, in the tan of slacks showing the lowest suitability level among Chinese-made women's wear, Korean-made women's suits in China had outstandingly high suitability level. In the case of jackets, however, the Korean-made women's suits went through more fixings, on average, than Chinese-made women's suits. In addition, more fixings were done for enlargement than for contraction, which necessitated the measure changes.

The aim of this study was to investigate the difficulties that Korean farmers and processors currently experience with respect to the market for Korean native chicken (KNC). This study also provides suggestions by which they can overcome these difficulties. In all, sixty-nine farmers and sixty-two processors participated in our investigation, which addressed 1) the current difficulties that KNC farmers face, 2) the current importance-satisfaction measures among KNC farmers and processors, and 3) the future direction of the KNC market: farmer and processor opinions. The respondents stated that the limited number of sales stores was the most difficult market condition they faced in raising KNC, followed by feed cost, animal disease, and poor production environment. Regarding issues of importance and satisfaction, origin in raising step and slaughtering in the processing and distribution step were considered the areas most in urgent need of improvement, given farmers' and processors' high levels of dissatisfaction with these. Both the free-range farming system and the concept of animal welfare are growing in importance, given consumers' interests in these areas. As to opinions on the direction of KNC development, menu development was cited as most important, followed by public advertisement, accessibilities, business aid, and breed development. Consequently, the results show that well-organized support from both the government and related industries is needed, as chicken farmers and processors cannot resolve certain limitations inherent in the KNC industry on their own.
