This article examines the location strategies of coffee franchises in Gyeonggi province. Due to its large population, broad area, and diverse industrial structure, Gyeonggi province is an ideal dataset for empirical testing of the location strategies. We collect the addresses of five major coffee franchises stores, convert them into geographic coordinates using Google Maps Geocoding API, and compute Haversine distances both between stores of the same franchise and between stores of different franchises. This novel approach leads to three discoveries. First, coffee-consuming age population is positively related to the number of stores and more strongly for commercial areas with a large floating population. Second, one third of Starbucks stores have another Starbucks store within a radius of 300m, which empirically confirms the 'Focused Destroy Strategy' of Starbucks that has multiple stores in central business districts. Third, for 80% of Starbucks stores, we can find Ediya stores within 500m, which supports Ediya's 'Next-to-Starbucks Strategy'. Our research methods can be efficiently applied to the analyses of other retail businesses such as convenience stores, fast food restaurants, and mobile phone shops.

This paper aims to clarify the process of institutionalization of customary land ownership along with the expansion of coffee plantation in Dak Lak Province, Vietnam. Vietnam is the second-largest coffee exporter in the world. Most of the coffee areas are concentrated in Dak Lak-a province of commercial agricultural production. The expansion of coffee plantation in Dak Lak have brought a severe competition of land resources, and resulted in the transition of land ownership scheme from customary commons by ethnic minorities to those of exculsive private assets which is secured by the state. Institutionalization of customary land ownership in Dak Lak, however, was differently happened according to the geography from the center of state power as well as the value of land resources. In this paper, the authors argue that institutionalization of customary land ownership in Dak Lak was a result of compromising between statemaking process in the frontiers and "everyday resistance" of ethnic minorities, comparing 3 geographically different ethnic minorities' communities.

Metabolic syndrome is associated with risk of developing cardiovascular disease and type 2 diabetes, and incidence of metabolic syndrome is showing an increasing trend. Recently, coffee intake is argued to have an effect on the gut-brain axis, and it is widely recognized has being associated with many beneficial effects, including those related to metabolic imbalance. However, it is essential to understand how the dietary aspects of coffee intake and type of coffee intake affect diet and overall health. The association between coffee consumption and health is still controversial, and the average body weight of the Korean population is increasing. Therefore, this study focused on analyzing the effects of instant coffee (particularly instant coffee mix) in Korea, especially with respect to metabolic syndrome. The study was conducted on participating subject's that visited Sun-Han hospital, and instant coffee mix intakes and metabolic risk factors during the study period were examined from July 2015 to June 2016. The results showed that waist circumference (r=0.405, P=0.036) and serum triglyceride level (r=0.435, P=0.023) were positively correlated with instant coffee mix intakes. In addition, instant coffee mix intakes were significantly associated with serum triglyceride level in subjects who consumed more than 1 cup/d of coffee (P<0.05). Therefore, subjects should be careful about fat intake and be educated about the type and frequency of coffee intakes.

Changes in contents of amino acids, caffeine, trigonelline, chlorogenic acid, and monosaccharides in green coffee beans during roasting were investigated. During roasting, amino acid contents of Arabica and Robusta coffees decreased by 30%, among which cysteine, serine, lysine, and arginine contents markedly decreased, whereas those of glutamic acid, glycine, alanine, valine, isoleucine, leucine, and phenylalanine slightly decreased or increased. Caffeine contents of Arabica and Robusta were 1 and 2%, respectively, and remained unchanged during roasting. Trigonellin content of Arabica (0.87%-0.90%) was slightly higher than that of Robusta (0.74%), and 50 to 65% trigonellin degraded when green beans were heavily roasted. Chlorogenic acid levels of Robusta and Arabica were 4.82, and 4.38-4.66%, respectively. About 90% chIorogenic acid degraded with heavy roating. Total monosaccharide contents of Arabica and Robusta were 38.1-38.7 and 37.7%, respectively, and gradually decreased with roasting.

As business activities of firms for maximizing profits has resulted in increases in economic, social and environmental problems in regional geographies, they have stimulated some social activities through enhancing their public image and justifying their conducts. In fact, firms have been given concerned with a decrease in profits due to the promotion of their social activities required by local communities. However, firms are able to create shared value resulted in added value creation centering on shareholder as well as stakeholder by expanding increases in economic and social values. Therefore, the main purpose of this research is to draw an index which is able to evaluate the mechanism of virtuous circle resulted from creating shared value(hereafter CSV). At the same time, it has attempted to analyze some limits to and real effects of CSV by the index. The paper has analyzed the CSV of certificated coffee by using the index of sustainability in the Vietnamese coffee industry. The introduction of certificated coffee showed positive effects in the order of environmental, economic and social indicators. However, the structure of closed decision-making in Vinacafe, which is a state-firm, has not able to secure enough economic profits for CSV, leading to some limits to the formation of virtuous circles in the Vietnamese certificated coffee industry.

The purpose of this study was to compare the preventive effects of green tea and coffee drinking on postprandial hypotension in the elderly. A total of 30 women ($81.2{\pm}6.8years$) who had experience of postprandial hypotension participated 3 interventions by random order allocation. During the experimental interventions, each participant had a cup of instant coffee (60mg caffeine), or green tea (15.8mg caffeine) after lunch, and control group had only their lunch. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were measured with 15 minute interval from 30 minutes before the meal to 120 minutes after the meal. The preprandial SBP and DBP were not significantly different between three groups. Postprandial SBP reduction measured at the 1 hour after meal was significantly smaller in coffee group compared to the control group, whereas green tea group was not ($-15.1{\pm}17.9mmHg$ vs $-13.4{\pm}22.4mmHg$ vs. $-4.1{\pm}18.6mmHg$ for control, green tea, and coffee group, respectively, p=.032). Likewise, DBP decrement at the 1 hour after meal was significantly smaller in coffee than control group ($-12.8{\pm}13.0mmHg$ vs $-6.9{\pm}16.6mmHg$ vs $-0.8{\pm}13.4mmHg$ respectively, p=.033). The HR response of the three groups were not significantly different throughout the intervention. Coffee drinking was potentially beneficial for preventing postprandial hypotension and resultant falling event.

In this study, we investigated the change in lead content of canned coffee drinks while kept for 16 weeks in an incubator adjusted to $65^{\circ}C$. Our research aim was to ensure the safety of canned coffee purchased from vending machine and stores. The lead analysis were conducted by graphite furnace atomic absorption spectrometry after wet digestion using concentrated nitric acid. The results showed that the lead contents of all examined samples were very low at a level of not detected to 0.033 mg/L, and below 2 mg/kg, the Korean regulatory limit for the commodity. Also, no increase in lead content was observed over the elapsed time. Therefore, it appears that lead is not a hazard and need not be a concern in drinking canned coffee.

Physical environments of service firms have been found to influence on customers' quality and purchase intentions. This study began with the preposition that purchase of service products derived from utilitarian or hedonic needs would be different in the influential path. With cases of Korean coffee-shops, this study found ambient, interior, cleanliness of physical environment directly influence to customers' emotion but indirectly influences to purchase intentions. The study also found, differently from some previous studies, appearances of employees had no effect on emotion nor on purchase intentions.
