Twitter can spread and share all kinds of information such as facts, opinions, and ideas in real time. In this paper, we empirically compare and analyze the topic categories in Twitter with all top 100 users in each of geographic region. We mainly consider the relationships among regions and selected four regions: Global, Seoul, Tokyo, and Beijing. Each of the top 100 users in Twitter is classified into a specific category and then statistical analysis is conducted. Among eight topic categories, the "Arts" category is the largest and the second is "Life". The correlation between global and Seoul groups has the lowest value among the six pairs of relationships between regional groups, and this difference is statistically significant. We find that the Seoul, Tokyo, and Beijing regional Twitter groups, all in East Asia, have high topical similarity. Based on the correlation analysis, Seoul and Tokyo saliently show a sticky trend. The correlation coefficient presents very a strong positive correlation between Seoul and Tokyo. The correlation between the global group and the East Asian groups is relatively lower than that among the East Asian groups.

Objectives : It is necessary to manage herbal medicines based on effectiveness by comparing the efficacy of herbal medicines by region. In this study, we compared anti-oxidative activity and marker compounds of Eucommiae Cortex by regional groups. Methods : Eucommiae Cortex grown and harvested in Gangjin, Sancheong, Yeongwol, Jangsu, and Jecheon were used. Eucommiae Cortex was extracted in distilled water at $100^{\circ}C$ for 3 hours, and filtered. filtered. Extract samples were freeze-dried at $-80^{\circ}C$. Comparison of anti-oxidant activity in Eucommiae Cortex samples from regional groups was measured in 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) free radical scavenging, and ferric reducing antioxidant power (FRAP) between regional groups of Eucommiae Cortex. In addition, high-performance liquid chromatography (HPLC) analysis was conducted to compare pinoresinol diglucoside concentration by regional groups. Results : HPLC analysis found that pinoresinol diglucoside concentration, widely known as the marker compound of Eucommiae Cortex, was the highest in Gangwon Yeongwol. There was a significant difference in anti-oxidative activity of Eucommiae Cortex between regional groups as discovered in DPPH, ABTS and FRAP assays. DPPH free radical scavenging was the highest in Jeonbuk Jangsu. ABTS free radical scavenging was the highest in Jeonbuk Jangsu and Chungbuck Jecheon. FRAP was the highest in Jeonbuk Jangsu. Conclusions : Although pinoresinol diglucoside concentration was high, anti-oxidative activity was not proportionately high. Pinoresinol diglucoside concentration was the highest in Gangwon Yeongwol. Anti-oxidative activity was the highest in Jeonbuk Jangsu.

This study regarded fashion selection criteria as clothing consumption value and desired fashion images, and examined selection differences according to regional subculture groups. Clothing consumption value is a direct value that people seek with clothing products and a perceived value which is divided into emotional, social, price, quality values. Fashion image which is a feeling communicated to others by wearing a certain fashion style is the most superficial value. Multivariate Analysis of Variance (MANOVA) was performed to test the differences between regional subculture groups in clothing consumption values and desired fashion images. We found some differences in clothing consumption value specifically in emotional value and social value. The group differences were remarkably significant in fashion image comparison. 'Kang-nam' group pursued 'lively', 'sophisticated', 'charming', feminine', 'gorgeous' image more than 'Kang-buk' group. While 'Kang-buk' group produced lower scores in ideal fashion images, the group had significant higher seeking in 'sportive' image compared to 'Kangnam' group.

The purpose of this study was to analyze the regional ripple effects and residents' perceptions of the West Coast Highway on four regions of Chung-nam province. The data was collected through questionnaire interviews with 400 residents in four regions of the west coast area. After data cleaning, the statistical methods used were confirmative factor and cluster analysis with 309 sampled from four regions of Dangjin, Boryong, Seosan and Taean. The results of this study were as follows. First, it is classified, according to the residents' perceptions against the opening of the West Coast Highway, into four groups. Group A is the people who haven't lived there long and mainly consists of relatively young (30's-40's) males, while Group B is the people with lower incomes and middle-aged males (40's) who have lived there for 11 to 20 years. Group C is mainly the people who are middle-aged housewives in their 40's and who haven't lived there long and with a relatively higher income. Group D is the people who lived for less than five years and had lower incomes than other groups. The results show that their perceptions against the influence of regional development differ demographically from each other. In conclusion, it was determined that most of them were concerned that it, coupled with the construction of the West Coast Highway, would damage the surrounding countryside but believed it would contribute to the growth of the region's economy. Whereas groups A and B seem to acknowledge the necessity of regional development and environmental protection, groups B and D appear to be more content with the tourism development derived from the West Coast Highway and are paying more attention to such plans than other two groups.

The purpose of this article is to introduce and describe the case of Fukuoka Next-generation Social System Creation Hub based on the conceptual framework of regional innovation platform strategy. In short, it is a "government-issued" regional innovation platform strategy to improve innovativeness with limited creative capital through "borrowing" not money but network, wisdom, know-how, and ideas from each other between some stakeholder groups in a region. The Fukuoka Industry, Science & Technology Foundation, which is the coordinating institution of the whole program, plays the role of a platformer to unify various projects into the program crossing borders between stakeholder groups for building regional innovation platforms that lends intensive support to feedback loops between the program facilitator and its partners in the program. Thanks to being a government-issued one, it could be tied together with some wide ranging issues of policy on social innovations, such as the "low carbon society" or the "health and longevity society." But at the same time, it is a concern that many regional research institutions that have innovative potential and diverse ideas become governed by the platform without their noticing it and dealt with in the same way based on "selected" and "designated" strategic goals. Therefore, it seems that a regional innovation platform strategy is a kind of "double-edged sword" in public policy in the era of "panopticism of bureaucratic society" in Japan.

본 연구는 우리나라의 지역 소비지출이 지역소득 증대에 미치는 영향을 분석하기 위한 것이다. 실증분석을 위한 계량경제기법으로는 패널공적분, 합리적기대 및 FM-OLS 공적분추정법을 적용하였는데 그 결과에 의하면 지역소득이 현재의 지역소비 뿐만 아니라 전기의 지역소득과 정(+)의 관계를 유지하고 있어서 수요측면을 활용한 지역소득 증대의 가능성을 시사하고 있다. 시도별 한계소비성향과 지출승수에 의하면 한계소비성향의 상위그룹은 지역 소비지출을 증가시킬 경우 지출승수 효과에 의해 지역내총생산이 증대되는 반면, 중위 및 하위그룹에서는 그 효과가 미미하거나 지역내총생산이 오히려 감소하는 것으로 분석되었다. 이와 같은 현상을 해소하기 위해서는 지역경제의 운용에 있어서 시장기능을 강화하고 지역 소비지출의 확대를 통한 지역소득 창출체계의 구축이 선행되어야 할 것으로 판단된다.

The purposes of this study are to: (1) Compare the vowel production of English front vowels produced by Korean speakers using regional dialects and; (2) Investigate and compare the effectiveness of pronunciation training for each regional dialect group. To test these objectives, the English front vowels produced by five Youngnam dialect male speakers, five Youngnam dialect female speakers, five Kangwon dialect male speakers, and five Kangwon dialect female speakers were scrutinized. These dialect groups' vowel formants and length of English front vowels were evaluated, and the post-pronunciation training values were compared with those of pre-training values. The results indicate that pronunciation training is more effective for Youngnam dialect speakers, whilst both dialect groups have more success mastering the pronunciation of /${\varepsilon}$/ over /${\ae}$/.

This paper investigates the regional characteristics of street fashion in China. Yanji, Beijing, Shanghai were chosen as three different cities in terms of location, weather, population, and industrial structure. A total of 592 pictures were collected through an internet and fashion magazine search for street fashion in Beijing and Shanghai in addition photos were taken for those in Yanji. Pictures of each city were classified into groups based on overall images covering top, bottom, and accessories to identify the characteristics of style in each group. The classification process included 2 stages. In the first stage, it produced 2 groups: formal and casual. The second stage divided formal into business formal and retro formal; casual was divided into II sub-groups that were easy, sporty, feminine, sexy, ethnic, girlish, nippon, trendy, bulky, military, and mixed. Easy casual showed the highest frequency for 3 cities and military style showed the lowest. Shanghai showed higher frequency in sporty, trendy, and military style than other cities. Each style exposed the similarities and differences in the cities that reflected different regional characteristics.

The regional centrality plays a very important role in national and regional planning and it is measured by data such as people, goods, and information flows among regions. The inter-regional flows are usually considered by only direct flows, yet indirect flows, which are generated accordingly from direct flows, are not critically considered. Most centrality studies have also hardly reflected the indirect flow in the network analysis. This study demonstrates the significance of the indirect flows to enhance accuracy of the regional centrality. The nationwide dataset of inter-regional commuter traffic matrix is used in this study and analysed into two groups; one to consider only direct flow and the other both direct and indirect flows. The results indicate remarkable differences of centrality raking between two groups such as Yeongam of Jeonnam Province(+60th), Eumseong of Chungbuk Province(+57th), Gwacheon of Gyeonggi Province (-35th), and Nowon of Seoul (-32nd). It clearly shows the significant influence of indirect flow for regional centrality study. This also reveals regional centrality ranking in Korea by considering direct and indirect flows of commuters. Jung, Gangnam, and Jongno of Seoul are categorized in the highest rank group and Ulleung of Gyeongbuk, Ongjin of Incheon, and Jindo of Jeonnam are in the lowest group. The top group includes seven districts of Seoul, two of Busan, and one of Gyeonggi Province. The bottom group includes mostly island and costal areas. As this study shows an accurate method of centrality measurement, it has a significant implication to lead an effective regional planning.

Purpose: Blood hemoglobin levels are known to influence response to radiotherapy. This retrospective analysis compared the effect of hemoglobin levels upon response to radiation among patients treated with radiation alone (by accelerated hyperfractionated radiotherapy) versus those treated with concurrent cisplatin chemoradiotherapy. Materials and Methods: Among patients treated for locally advanced carcinoma of the cervix (LACC) during 2009-10, a total of 60 fulfilled the eligibility criteria. In this time frame, external beam radiotherapy was delivered with either concurrent chemoradiotherapy (CRT, n=31) (45Gy over 25 fractions, with weekly cisplatin at 40mg/m2), or with accelerated hyperfractionated radiotherapy (AHRT, n=29) (20Gy over 10 daily fractions over the first two weeks, followed by 30Gy over 20 fractions over the next two weeks, with two fractions of 1.5Gy per day, without the use of chemotherapy). Mean weekly hemoglobin (MWH) levels of all patients were calculated as the arithmetic means of weekly recorded blood hemoglobin levels. As per MWH, patients in both of the AHRT or the CRT groups were classified into two subgroups-those with MWH between 10-10.9g/dL, or with MWH>11g/dL. Complete response (CR) to external beam RT phase (prior to brachytherapy) was declared after clinical examinations and computed tomography. The CR rate was noted for both MWH sub-groups within each of the AHRT and CRT groups. Results: Within the AHRT group, patients with MWH>11g/dL had a much better CR rate in comparison to those with MWH:10-10.9g/dL (80% vs. 21.1%) which was statistically significant (p 0.0045). Within the CRT group, there was no significant difference in the outcomes within the MWH>11g/dL and MWH:10-10.9g/dL sub-groups (CR rates of 80% vs. 61.9%, p=0.4285). Conclusions: The importance of maintaining a minimum hemoglobin level of 11g/dL during RT is much greater for patients treated with RT alone, than for patients treated with concurrent chemoradiotherapy. Enhanced haemoglobin levels during RT may to an extent negate the ill-effects that may otherwise arise due to non-use of concurrent chemotherapy.
