This study investigated the recognition and preference of a chicken menu according to the age of adults in the Jeonbuk area. Self-administered questionnaires were collected from 394 adults (male 55.3%, female 44.7%) residing in the Jeonbuk area. Descriptive and comparative statistical data analysis was completed using SPSS v. 12.0. The frequency of consumption of chicken-containing foods for the younger group (20~30 years old) was significantly higher than the frequency of older groups (over 40) (p<0.001). The younger group also consumed chicken food through a delivery service, whereas the older group consumed chicken through delivery and self-cooking. Approximately 50.0% of the older group preferred the chicken leg whereas 38.1% of the younger group preferred the chicken breast (p<0.001). The most highly recognized chicken menu items, among 36 chicken menus, were Samgyetang (2.93), chicken dori-tang (2.93), and fried chicken (2.93). The older group knew about a chicken menu made by traditional cooking much more than the younger group. The most highly preferred chicken menu item was spicy fried chicken (4.18). The preference for Western-style chicken menu (e.g. Cajun chicken salad, chicken sandwich) was significantly higher in the younger group than the older group (p<0.001, p<0.05). Therefore, to develop a new chicken menu, the consideration of favorite chicken parts and an age-based menu is necessary.

This paper analyzes the effects of population aging on regional differentiation from the New Economic Geography perspective. The addition of old-age population variable affects the price index, income, nominal wage, and real wage derived in the short-run equilibrium. Using the new model, we can better explain industrial agglomeration patterns corresponding to the new long-run equilibrium. As the real wage criterion does not properly take the old-age group into account, we employ the indirect utility function as an additional condition for equilibrium. We further consider tax as a policy tool for achieving a better long-run equilibrium. This would enable the government to direct the economy toward a particular equilibrium desired in the face of population aging.

As smartphones permeate the consumer lifestyle, branded application and mobile shopping have also received increased attention as an important marketing channel. This study identifies the general information about the use of smartphones, attitudes toward fashion applications, and mobile shopping intentions for smartphone users. Focus group interviews were conducted and 22 interviewees participated. The age of the participants ranged from 21 to 45 years old (55% were females). When examining the motivation to adopt a smartphone, respondents presented the comparable characteristics of early adopters and late adopters according to the time of adoption. Most respondents over the age of 30 showed some troubles to use a smartphone; however, participants in their 20s tended to enjoy exploring the new technology. More than half of respondents were aware of fashion applications, but were dissatisfied with fashion apps and used them infrequently. Respondents pointed out that fashion related apps were not too practical because they were not updated regularly, provided only limited information, and focused on brand promotions. In order to increase the intention to adopt mobile shopping, the price and payment security system needs to be considered. This was an exploratory study to identify the possibility of fashion branded apps as a major distribution channel. The findings of this study provide fundamental information to formulate marketing strategies for fashion businesses that have developed fashion apps.

Kaposi's varicelliform eruption is a more or less generalized infection of the skin, and sometimes of internal organs, with herpes simplex, vaccinia or Coxsackie virus A 16 ; it appears in people who have atopic dermatitis or some other skin diseases. There is a predilection for infants and children, but no age-group is exempt. We reported 3 cases of Kaposi's varicelliform eruption with atopic dermatitis. They had characteristic multiple umbilicated vesicles on the sites that atopic dermatitis had been involved. A 14-year-old boy and a 2-month-old infant had fever. A 17-year-old boy had wide-spread vesicles. All three patients showed multinucleated giant cells on Tzanck test, that suggests herpes simplex virus origin. They were treated with acyclovir. Within 1 to 2 days after the initiation of the therapy, new lesions had ceased to develop. Most of the lesions were cleared in 7 days without complication.

Objectives: The basis research of aged people's healthcare technology is very important, because our nation goes into an aged society rapidly. Especially in traditional medicine, pulse shapes of aged people were supposed to weak and empty pulse until now, but any objective measurement and compare research do not taken. Methods and Results: Therefore in this study we design observation study to find characteristic of pulse between younger group (age $20{\sim}30$) and elder group (age $43{\sim}80$) in Busan area. We used 3-dimensional pulse analyzer '3-D MAC' (Daeyomedi Co., Ltd.). And major parameters for comparison are 1) pulse height (h1), 2) applied pressure, 3) pulse power (energy), 4) high pressure duration (w) and 5) R-AI. Conclusions: According to analysis result, elder people's pulse has more large value in pulse height, applied pressure and pulse power than younger's that. It reveals that elder people in modernized lifestyle has Yang symptoms as well Yin symptoms. Consequently we need new method to care elder people's health, and this means more important direction than old text book. From now on verification research with objective diagnosis device like 3-D MAC, must be activated to build of evidence in traditional medicine. Cause traditional medicine's spirit of care and prevention is suitable to care elder people's cardiac and cerebral vascular disease those are have close relation with elder people.

Purpose: The dental age estimation of children is performed using dental maturity. Postmortem missing of the anterior teeth or the distortion of image of the anterior teeth in panoramic radiographs can make it difficult to analyze the development of the anterior teeth. This pilot study was conducted to derive a new age estimation method based only on the developmental stage of mandibular posterior teeth. Methods: This study was conducted using panoramic radiographs of 650 subjects aged 3 to 15 years old. The dental developmental stages of the lower left first premolar, second premolar, first molar and second molar were evaluated according to the Demirjian's criteria. The intra-/inter-observer reliability was evaluated, and multiple linear regression analyses were performed including the developmental stage of each tooth as an independent variable. Results: The intra-/inter-observer reliability was 0.9626 and 0.8877, respectively, and showed very high reproducibility. Multiple linear regression analyses were performed for males and females, and the age calculation table was derived by obtaining the intercept and the coefficient according to the development stage of each tooth. The coefficient of determination (r²) of the age calculation method was 0.9634 for male and 0.9570 for female subjects, and the mean difference between chronological age and estimated dental age was -0.42 and -0.21, respectively. Conclusions: This pilot study evaluated the developmental stages of four lower posterior teeth in the Korean group according to Demirjian's criteria, and derived age estimation method. The accuracy was lower than when more teeth were used, but it will be useful to estimate age of children when the anterior teeth are difficult to accurately analyze.

This study was carried out to evaluate diagnostic criteria of noise-induced hearing loss (NIHL) among-workers in an iron foundry. Of 1,093 workers under the observation of noise-specific health examination, 184 workers were selected by way of first and second screening audiometric examination. A questionnaire survey, otological examinations, Rinne test and audiometric test were performed and the results were as follows ; The degree of hearing impairment in the left ear was more severe than in the right ear (p<0.05). The difference between hearing threshold of the first and the second hearing test at 1,000 Hz was about 5 dB with a narrow range of deviations while the difference at 4,000 Hz was about -7 dB with a wide range. Of the total study workers, 84.8% were tested within 15 hours away from noise exposure, and the rest after 16 hours. This study has identified that mean hearing loss at 4,000 Hz showed a significant statistical difference among the two study groups while mean hearing loss by 4-divided classification did not. The same phenomena were observed between the group with and without tinnitus and between the group with and without difficulty in hearing (p<0.05). Among 184 workers, 10 workers (5.4%) diagnosed as NIHL by old diagnostic criteria in contrast to 150 workers diagnosed as NIHL by the new diagnostic criteria. There was a significant difference between the two groups in the average hearing loss at 4,000 Hz and 4-divided classification (p<0.01), but there were no significant differences in age, the duration of employment, blood pressure and the duration wearing the personal hearing protector (p>0.05). If we apply Early Loss Index (ELI) method, some workers in younger age group diagnosed as NIHL by the new diagnostic criteria were fallen into within the normal range. In the mean time older age group show reverse results in contrast to the above finding. It is too early to confirm the value of the usage of the new diagnostic criteria in hearing examination. Further study is called for to verify the value of this criteria.
