KakaoTalk, a Korean mobile instant messenger service launched by KAKAO Inc., has grown remarkably popular in a short period of time, with its number of subscribers exceeding 100 million as of July 2013. Today, KakaoTalk is an everyday communication tool among most Korean mobile users. Although KAKAO has been the subject of many business and consumer studies, the KakaoTalk platform strategy has not been studied thoroughly. In this study, we analyze its platform strategy through the lens of several widely utilized frameworks such as Platform Leadership (Gawer & Cusumano 2002, 2008), Winner-take-all dynamics (Eisenmann et al. 2006), and Open Service Innovation (Chesbrough 2011). Our results show that Eisenmann et al (2006)'s "Winner-Take-All" platform best explains how KakaoTalk dominated its rivals, Mypeople by Daum Communications and Line by Naver Corporation. In surpassing its rivals, KAKAO delivered a solution to the 'essential problem' that mobile social communication should be upgraded from mobile companies' paid "Short Message Service" (SMS). By doing so, KakaoTalk fulfilled the first requirement of Gawer & Cusumano (2008)'s "Coring" strategy, which explains how a new platform is created. KakaoTalk also satisfied the second requirement of "Coring" by providing economic incentives for KakaoTalk members to interact through its Games and Items store. Actively accepting its customers' ideas and upgrading its services, KAKAO reinforced its platform leadership to its customers and put Chesbrough (2011)'s "Outside In - Open Service" innovation strategy into practice.

A survey conducted on 1,103 patients or caretakers visited Korean medical clinics and hospitals between August 25, 2011 to September 30, 2011 by the Ministry of Health and Welfares and Korea Institute for Health and Social Affairs was analyzed and obtained following results: 1. For sociodemographic distribution, female(813) outnumbered male(290) patients with majority of patients ranging from 30s to 60s. Married patients(793) outnumbered unwed(150) patients and 65.0% with higher than high school education. Statistical significance was seen in gender, age, marital status, and education level but no significant difference for status of employment, income level, and types of insurance between the clinics and hospitals. (P<0.05). 45.1% had less than \2,000,000 in monthly salary and most of coverage was provided by either regional or work insurance. 2. 67.9% of the patients rated health conditions to be better than average and 32.1% listed as poor. People in good health showed tendency to visit Korean medical facilities. Musculo-skeletal conditions such as arthritis, ankle sprain, lumbago, muscular injury, and frozen shoulder were common conditions, followed by gastric disorders, common cold and herbal tonics. No significant difference was observed between the clinics and hospitals for above conditions, but significance was seen in atopic dermatitis, stroke, and sequela from traffic accidents (P<0.05). 3. Ten most common conditions addressed at Korean medical facilities were lumbago, arthritis, muscular injury, back sprain, gastric disorders, ankle sprain, common cold, herbal tonics, frozen shoulder and stroke. Major treatment modalities rendered were herbal medicine, herbal supplements, acupuncture and moxibustion, cupping, tuina, and Korean midical physical therapy. No significant difference existed between the clinics and hospitals. 4. All modalities showed at least 85% effectiveness. No statistical significant difference between the clinics and hospitals except for herbal decoction. (P=0.0452) 5. 88.3% of responses showed treatment satisfaction with significant difference between the clinics and hospitals (P=0.002). The occurrence of side effects was at 2%, mostly corning from treating digestive, skin, kidney disorders and neurological issues. No significant difference was observed between the clinics and hospitals. From the above results, the typical population visiting Korean medical facilities can be summarized as being middle aged female with relatively higher education and moderately low income. The health condition is generally good and the purpose of visit is to receive traditional treatments of acupuncture, herbal medicine, and physical therapy. Treatment efficacy and satisfaction were high with no significant differences between the clinics and hospitals.

Design, to all of us living in the 21st century, is not just an action that revs up the production and consumption as an added value of an industry, but it is recognized as a broader social and cultural action in practice. The purpose of this study is to broaden the role of design as a principal body producing culture, and to proclaim that design itself has to have self-sufficiency as culture. The study starts from a hypothesis that the action of design should be at the core of cultural industry. The study includes studying the documents on and analyzing the current status and case studies of cultural industry and design policies for macro view. Comparative research and analysis of how designers from three countries, Korea, United States and England, perceive policies is a microscopic part of this study. The methods for this study include survey for quantitative research in Korea, United States and England, and intensive interviews for qualitative research to explain past facts and the current situation of design policies. The survey compares design professionals of three countries, and the intensive interviews are done with manager level design professionals who are both decision makers and policy makers. On order to prove the appropriateness of the survey structure, three pilot studies and a pre-test were carried out. As shown in the verification of the subject of study, if, in the cultural industry which was considered to be the blossom of 20th century, the blind running without intervention of reason still keeps its former state and is unable to go beyond history, we will not be able to enter the age of mentality and fall behind. The value of design that we shall judge depends on the dialectic of 'past' and 'present' regarding the principle of enlightenment, and it will open up a new philosophy, a new civilization and a new world.

Background : Strategic planning is an organizationwide or systemwide, ongoing look into the future usually of 2~3 years, based on objective analysis of the current environment and trends, but it can incorporate both short-term and long-term goals. The strategic planning process includes external analysis, internal analysis, issue analysis, development of mission, vision and values, and lastly development of organizational goals and objectives. As a part of the strategic quality planning process, certain service lines, important organizationwide functions, or key processes supporting these functions can be prioritized to expedite and roll out certain strategic goals. This is called strategic quality initiatives. Methods : We organized a quality improvement team, a subgroup of 21st century vision planning corps of our medical center, and pursued QI activities for improvement of healthcare environment, particularly in the admission setting. We developed a strategic quality initiative based on the results of patient satisfaction surveys, and carried out functions of self-directed work team. Results : The strategic goal was to be the benchmark for peer group hospitals in Korea for providing cost-effective best-practice. The QI team included 3 medical doctors, 1 nurse, 1 social worker, and 1 QI consultant as well as many operational members to support services and quality initiatives met every Tuesday for 18 weeks. Outcome objectives were to improve patient satisfaction score. The issues included in the objectives were comfort, temperature, noise, cleanliness of the admission wards, quality and education of patient meals, matters regarding the admission process, and an appurtenant facility such as restaurant or convenience store. Every issue was discussed and recommendations, conclusions and opportunities were implemented. Conclusions : By developing a strategic quality initiative as a part of the strategic quality planning process, and pursuing a self-directed work team, certain sen/ice lines, important organizationwide functions, or key processes supporting these functions can be improved effectively within a short period. Strategic quality initiatives serve to support, or roll out, certain strategic goals that are relevant to performance improvement and development of specific measurable outcome objectives, and associated performance measure for each initiative. Each strategic quality initiative should include a statement of intent outcome objectives, and performance measures. We will come back with follow up of the strategic quality initiative, for improvement of healthcare environment, and results of patient satisfaction re-survey.

This study attempted to identify the health behaviors and related factors of lifestyle related diseases among some public officials. The study subjects were 729 administrative officers of the general public office of the government in D metropolitan city. The data collection was conducted by self-administered questionnaire from February 1 to March 31, 2016. As a result, the health behavior score for lifestyle related diseases showed a significant positive correlation with vulnerability, the effectiveness of health behavior and information obtained from the media about lifestyle-related diseases, while it showed a significant negative correlation with the barriers to health behaviors concerning lifestyle related diseases. As a result of the covariance structure analysis, vulnerability and seriousness about lifestyle related diseases were the most important factors affecting health behavior for lifestyle related diseases. The next most important factors were a family history of lifestyle related diseases, information obtained from the media, effectiveness of and barriers to health behavior, instrumental support, and emotional support. These results suggest that each factor constituting the Health Belief Model (HBM) (perceived vulnerability and seriousness about lifestyle related diseases, perceived effectiveness and barriers to health behaviors, family history of lifestyle related diseases, information obtained from the mass media about lifestyle related diseases, social support network for lifestyle related diseases) is an important factor to consider in practicing health behaviors for lifestyle related diseases. Therefore, it is important to accurately understand the factors related to the practice of the health behaviors of the subjects and to manage them continuously.

BACKGROUND/OBJECTIVES: Irisin, a newly identified hormone, is associated with energy homeostasis. We investigated whether aged garlic extract (AGE) and exercise training intervention could improve body weight, insulin sensitivity, skeletal muscle fibronectin domain containing protein 5 (FNDC-5) levels, and plasma irisin in high-fat diet (HFD). MATERIALS/METHODS: Male Sprague Dawley rats were fed a ND (normal diet, n=5) or HFD (n=28) for 6 weeks. After 6 weeks, all rats were divided into 5 groups for the next 4 weeks: ND, (normal diet, n=5), HFD (high-fat diet, n=7), HFDA (high-fat diet + aged garlic extract, n=7), HFDE (high-fat diet + exercise, n=7), and HFDEA (high-fat diet + exercise + aged garlic extract, n=7). Exercise groups performed treadmill exercises for 15-60 min, 5 days/week, and AGE groups received AGE (2.86 g/kg, orally injected) for 4 weeks. RESULTS: Significant decreases in body weight were observed in the ND, HFDE, and HFDEA groups, as compared with the HFD group. Neither intervention affected the masses of the gastrocnemius muscle or liver. There were no significant differences in glucose levels across the groups. The homeostatic model assessments of insulin resistance were significantly higher in the HFD group, as compared with the ND, HFDA, HFDE, and HFDEA groups. However, skeletal muscle FNDC-5 levels and plasma irisin concentrations were unaffected by AGE or exercise in obese rats. AGE supplementation and exercise training did not affect skeletal muscle FNDC-5 or plasma irisin, which are associated with insulin sensitivity in obese rats. CONCLUSION: Our results suggest that the protection against HFD-induced increases in body fat/weight and insulin resistance that are provided by AGE supplementation and exercise training may not be mediated by the regulation of FNDC-5 or irisin.
