A survey was performed to present a scheme for building a healing forest park inside a city in consideration of the fact that healing forests are located in non-urban areas because of their nature, and are therefore not conveniently accessible to urban population (n=196). As a result, among 196 respondents to the survey, 74.5% indicated that it was necessary to build an urban healing forest park. In the case of the expected usage pattern, were an urban forest park to be built, the largest proportion responded that it would be used to "walk", followed by "rest and meditation" and then "meeting/talk/date". An analysis showed that the largest proportion responded that they factor in "Accessibility" (48%), followed by "Park condition" (16.8%), and "Vegetation type" (12.2%). According to the analysis of usage preference for healing therapy, it was shown that the largest proportion preferred "Terrain therapy" (37.8%), followed by "Exercise therapy" (19.9%), and "Naturopathy" (18.9%). The factor anlaysis of usage preference regarding urban healing forest park facilities showed that the components were divided into "Operation facilities" and "Natural healing space", and the largest proportion preferred "Trails for healing", followed by "Space or forest for meditation" and "Health promotion center", and then "Facilities for a exercise therapy". In building an urban healing forest park, we think that it is effective to introduce zones and facilities in consideration of park characteristics that are centered on everyday behaviors, such as taking a walk, which differ from those of healing forests located in non-urban areas.

Fat deposition in animal muscles differs according to the genetics and muscle anatomical locations. Moreover, different fat to lean muscle ratios (quality grade, QG) might contribute to aroma development in highly marbled beef. Scientific evidence is required to determine whether the abundance of aroma volatiles is positively correlated with the amount of fat in highly marbled beef. Therefore, this study aims to investigate the effect of QG on beef aroma profile using electronic nose data and a chemometric approach. An electronic nose with metal oxide semiconductors was used, and discrimination was performed using multivariate analysis, including principal component analysis and hierarchical clustering. The M. longissimus lumborum (striploin) of QG 1++, 1+, 1, and 2 of Hanwoo steers (n=6), finished under identical feeding systems on similar farms, were used. In contrast to the proportion of monounsaturated fatty acids (MUFAs), the abundance of volatile compounds and the proportion of polyunsaturated fatty acids (PUFAs) decreased as the QG increased. The aroma profile of striploin from carcasses of different QGs was well-discriminated. QG1++ was close to QG1+, while QG1 and QG2 were within a cluster. In conclusion, aroma development in beef is strongly influenced by fat deposition, particularly the fat-to-lean muscle ratio with regard to the proportion of PUFA. As MUFA slows down the oxidation and release of volatile compounds, leaner beef containing a higher proportion of PUFA produces more volatile compounds than beef with a higher amount of intramuscular fat.

비와 비례 개념은 독립적으로 발달하는 것이 아니다. 오히려 이런 개념은 곱셈적 개념 장의 일부분으로 서로 관련을 가지면서 발달하게 된다. 곱셈적 개념 장에는 곱셈, 나눗셈, 분수, 비, 유리수와 같은 개념을 포함한다. 본 연구에서는 이런 개념의 발달 과정이 어떻게 시작하는가를 알아보기 위한 목적으로, 한 초등학교 4학년 아동을 대상으로 비례추론 과제를 해결하는 실험 수업을 실행하였다. 연구를 통해 이 아동이 비형식적 전략을 전개하면서 어떤 도전에 직면하였는지 그리고 비와 비례 개념을 전개하면서 어떤 수학적 지식이 유용하였는지를 분석할 수 있었다. 이러한 연구 결과는 비와 비례 개념의 발달은 곱셈적 개념 장의 발달과 깊은 관계가 있다는 기존의 입장을 지지하는 것으로 나타났다.

The aim of this study is to analyse the adjustment of the proportion of segment duration in imitating voice. When imitating others' voices, how far is his/her original proportion of segment duration adjusted, and what is this adjustment like under various segments? In this study, I classified segments into consonants and vowels and consonants classified into obstruents and sonorants. The result of the analysis is as follows. ; (1)Individual variation in the proportion of obstruent is not significant, and when imitating, and its distribution is not typicalized. (2) Vowels has individual variation in the proportion of segment duration even under imitating. (3) Nasal has the most distinct individual variation even under imitating, compared with vowel and obstruent. For the further study, I should examine the characteristics of quantitative and qualitative changes in liquid (among sonorant) to find out which segment can best describe personnel characteristics of the proportion of segment duration in imitating voice.

PURPOSE: This investigation in the study aimed to assess to determine proportion and susceptibility makers of sarcopenia in Korean younger female aged 30 to 39 years. METHODS: To address the complex sampling design of Korea National Health and Nutrition Examination Surveys, appropriate individual weights were incorporated into the analysis. The data employed a stratified, clustered, multistage probability sampling design. A total of 2,098 participants were enrolled and categorized into two groups based on their skeletal muscle mass index scores. One hundred and twenty-four individuals were placed in the sarcopenia group, while 2,024 were allocated to a normal group. The study examined various markers as variables, including age, height, weight, body mass index waist circumference, skeletal muscle mass index, systolic and diastolic blood pressure, fasting glucose, triglyceride, and total cholesterol levels, and smoking and drinking habits. RESULTS: The study found that proportion of sarcopenia in this population was 3.78% (CI: 2.89-4.94) in sarcopenia group and 96.22% (CI: 95.06-97.11) in normal with weighed values. Several susceptibilities including height, weight, BMI, waist circumference, diastolic blood pressure, and total cholesterol levels were risk factor for sarcopenia (p < .05), exhibited significant differences between the sarcopenia and normal groups. CONCLUSION: This investigation provides the proportion of sarcopenia and identifies relevant susceptibility markers among community dwelling younger women in Korea.

Objectives : Previous studies showed that death certification by physicians was an important predictor to improve the quality of death certificate data in South Korea. This study was conducted to examine the proportion of death certificates issued by physicians and associated factors in South Korea from 1990 to 2002. Methods : Data from 3,110,883 death certificates issued between 1990 and 2002, available to the public from the National Statistical Office of Korea, were used to calculate the proportion of death certificates issued by physicians and to examine associated factors with logistic regression analysis. Results : The overall proportion of death certificates issued by physicians increased from 44.6% in 1990 to 77.6% in 2002 (mean: 63.5%). However, the proportion was greatly influenced by the deceased's age. In 2002, more than 90% of the deceased aged 51 or less were certified by physicians. A higher proportion was found among deceased who had tertiary education (college or higher) living in more developed urban areas. Conclusion : The information regarding the cause of death for younger, well-educated deceased in urban areas of South Korea may show a higher level of accuracy. Epidemiologic research using information on causes of death may well benefit from the continually increasing proportion of death certificates issued by physicians in the future in South Korea.

The purpose of this study is to reveal concrete evidence on how aesthetic preference is applied in product design by countries. Since the 19th century, the proportion has been examined various times, and the conclusions consistently showed the strong preference for the golden ratio (1:1.618). However, previous studies are mainly focused on western products that were designed by western designers, so when the same experiment conducted for the first time in Asia with the question of 'Is the Asian subjects also likes the golden ratio?', the result clearly revealed that Korean subjects have a significant preference for the root ratio (1:1.414) and perfect square (1:1). It demonstrates that proportion preference might be different by countries, and it also influences on everyday products. Moreover, there is not enough evidence of Asian product proportions. For this reason, this study will strive to expand the knowledge on Asian aesthetic preference by focusing on Japanese automobiles that were designed and produced in Japan. 55 iconic Japanese automobiles were analyzed for proportion and compared with 50 iconic German automobiles. The result shows that Japanese automobiles have a shorter length of 7:10 (1:1.414) ratio than German automobiles with 13:23 (1:1.769) ratio. This result proves that there is the difference in preference for the proportion of Japan and Germany, and it has already influenced on automobile proportions. This result has a strong value that finding the most appropriate proportion of automotive design is a major issue in new product development, so this can be adapted to various fields of the design process where strong cultural value exists.

디지털 게임의 등장이후 하드웨어 발전과 더불어 게임의 핵심 요소인 캐릭터는 인체비례론을 바탕으로 유저들이 선호하는 등신비율의 유형으로 변화하고 있다. 등신비율의 변화에 따른 게임에서 캐릭터의 독특한 이미지로 게이머들에게 인기가 많다. 현재까지 등신비율에 대한 연구는 아직 미흡하다고 사료된다. 본 연구는 게임캐릭터 개발에 있어 조형요소로서 인체비례가 가지는 중요성을 근간으로, 게임캐릭터들의 특성을 고찰하고, 게임캐릭터의 등신비율을 분류, 그 결과를 분석하는 연구방법을 통하여, 등신비율의 현황을 살펴보고, 앞으로 게임이미지에 미치는 영향에 대해 연구해보고자 한다. 분석한 다섯 가지 유형의 게임캐릭터는 독특한 이미지와 함께, 특성화된 등신비율일수록 유저들이 선호하며, 조형적으로 실제 인체보다 과장된 등신비율이 주를 이루는 것으로 분석되었다. 그래픽 배경화면에서 캐릭터가 상대적으로 작아 보이는 비례의 어려움을 조금 과장된 캐릭터를 활용하여 가시성을 높였다. 이 연구를 통해 게임캐릭터의 등신비율은 게임개발에 있어 게임이미지로서 매우 중요한 요소로 사료된다.
