본 연구는 토마토에 대하여 가지가 트랩식물로써 담배가루이를 효과적으로 유인할 수 있을지에 대한 잠재성을 평가하였다. 큰망초, 가지, 오이, 토마토에 대한 담배가루이의 선호성을 비교하기 위하여 선택성 조사가 수행되었다. 담배가루이 성충은 후각적인 자극보다는 시각적인 자 극에 더 민감함을 보여주었고 큰망초보다는 오이와 가지를 더 선호하였다. 가지와 오이의 담배가루이 유인률은 각각 82.3%와 82.5% 였다. 가지 는 오이보다 관리측면에서 더 쉽기 때문에 우리는 본 실험에서 오이를 제외하였다. 담배가루이 성충에 대한 가지의 유인률은 토마토의 초장과 같 거나 더 클 때 90% 이상 이었다.

This study observed the effects of ankle strengthening exercise and whole body vibration on the balance ability of older adults, thereby intending to provide basic materials for intervention methods aimed at improving older adults’ balance ability. The subjects were 20 older adults who had experienced a fall. They were equally divided into two groups. Ankle strengthening training was applied to one group and ankle strengthening training and whole body vibration were applied to the other group, a timed up and go (TUG) test and Tinetti performance oriented mobility assessment (POMA) were performed, and changes in the subjects’ limits of stability were observed. The TUG and POMA results significantly differed between before and after the experiment in the angle strengthening training (AST) group and the angle strengthening training with whole body vibration (ASTWV) group. In addition, the interaction between timing and each group was statistically significant. The limits of stability significantly changed after the intervention in both groups. Differences in the posterior and right limits of stability were significant between the AST group and ASTWV group. Therefore, ankle strengthening exercise and whole body vibration improve older adults’ balance maintenance and reduce falls or the risk factors for falls in older adults.

This study aimed to evaluate the surface area and velocity of center of pressure (COP) during one leg standing by stimulating the sensory system in normal adults. Thirty subjects were enrolled in this study. Subjects were asked to stand on one leg during testing conditions. Testing conditions included 6 different sensory stimulations as follows: eyes opened, eyes closed, eyes opened with vibrator, eyes opened with head-mounted display (HMD), eyes opened with vibrator and HMD, and eyes closed with vibrator. During each testing condition, the surface area and velocity of center of pressure were measured. There were significant differences in the mean surface area and the mean velocity of COP between the “eyes opened” condition and the other five testing conditions (p<.05). However, in the comparison between the “eyes closed” and “eyes opened with HMD” conditions, there were no significant differences in the tested parameters. This study shows that closing eyes or keeping eyes opened while using HMD to experience virtual reality has the same effect on one leg standing balance. This finding should be considered in the evaluation or intervention of balance, especially one leg standing balance and balance while standing with a small base of support.

The purpose of this study was to analyze average kimchi intake, general characteristics, frequency of daily meal intake, intakes of vegetables and fruits, and nutrient intakes in four serving size groups based on data from the Korea National Health and Nutrition Examination Survey 2010~2012. The results showed an average amount of kimchi intake in subjects of 115.6 g, ranging from 0 g to 605.94 g. For daily meal intake except snacking according to kimchi serving size, all daily meal intakes increased significantly with increasing kimchi serving size (p<0.0001), and tendency of kimchi intake increased with more eating-out. As kimchi serving size increased, total intakes of vegetables and salted vegetables increased significantly (p<0.0001). However, unsalted vegetables intake did not show significant difference. Intake of fruits also increased with increasing kimchi serving size. As the serving size of kimchi increased, intakes of energy, carbohydrates, protein, fat, sodium, and potassium increased significantly (p<0.0001). For intake of sodium, intakes of all groups exceeded 2,000 mg, which is the recommended level for Koreans. Moreover, the fourth serving size group consumed three times (6,546.35 mg) more sodium than the recommended level.

The Chinese market has played an important role for the luxury industry in the past years, with double-digit yearly growth (except for last year). Luxury brands have tried to design strategies to meet the local requirements, be it in terms of retail formats or communication strategies. However, Chinese luxury consumers are evolving in terms of consumption habits and materialistic value: observations from the field show that there is less and less emphasis on logo display among certain consumers (Dubois & Laurent, 1994; Lin & Wang, 2010). Such changes might affect also young consumers, which already stand for a great share of luxury consumers (Source: Red Luxury,2012). Besides, past studies on Chinese consumers’ attitudes toward luxury and values behind luxury consumption have often relied on student-samples, acknowledging the potential limitation to their results due to a potential lack of representativeness of the population interviewed. Few studies have provided analyses of the causes of the values and behaviours of young Chinese customers towards luxury product consumption, focused on them as ‘young people’ (Wang et al., 2012; Xue & Wang, 2012). Besides, most of those that tried to do so relied upon student samples of Chinese students studying abroad (in the USA or Europe) (Chen & Kim, 2013). This paper attempts to investigate the contemporary young Chinese consumers’ behaviour towards luxury consumption, segmenting them into two groups : the international student group and mainland Chinese young consumer group. A quantitative survey collected data from 104 respondents within a month where the snowball sampling method was applied to broadcast both online and offline questionnaires. Qualitative data was analyzed through lexical analyzis, while quantitative data was analyzed with the help of SPSS (Levene-test and T-tests). This study mainly focuses on four features: Chinese culture, materialism, young Chinese generation culture and buying motivation. The results of the study mainly indicate that there have been some changes between generations. One such change is that Chinese youths are more individualistic than what was found in previous studies, and another change is that young Chinese consumers hold different points of view towards the values of luxury consumption. As far as differences between international students and local young people from Mainland China are concerned, we found the following differences: • Finding 1: International students purchase luxury products to fit-in with their friends & because they want others to view them as a member of the upper class & as a successful person more than their local fellows. • Finding 2: International students’ income is more able to support them purchase luxury products than for young locals, and they are more inclined to save money to buy luxury products that their local fellows. • Finding 3: Mainland Chinese young people usually go luxury shopping with their parents more than international students do and claim they will still purchase luxury products even if prices increase more than them as well. • Find 4: Purchasing luxury products make local young people happier than international students, and they care more about the style (as opposed to price) of luxury products than these lasts.  We believe such findings will help luxury companies refine their strategies for the coming generations and help researchers notice on which dimensions of luxury consumption using expatriated Chinese students might have an impact and lead towards biased results.

The purpose of this study was to synthetically examine the relationship between systemic diseases and periodontal diseases. The data of the Fifth Korea National Health and Nutrition Examination Survey were used. SPSS 18.0 for Windows was applied for statistical analysis. The surveyed data were analyzed by using independent sample t-test for the difference between Body Mass Index and clinical test according to the existence of periodontal disease, and X2test for the relationship between periodontal disease and systemic disease. Multiple logistic regression analysis was used in order to figure out the influence upon the existence of periodontal disease prevalence among general characteristics and relevant factors to systemic disease. As results, the value of high density lipoprotein (HDL) and HBA1C were statistically significant, depending on the presence of periodontal disease. As for the relationship between periodontal disease and systemic disease, hypertension (odds ratio 1.362, p<.05), cardiovascular disease (odds ratio 2.118, p<.05), arthritis (odds ratio 1.289, p<.05) and cirrhosis (odds ratio 6.124, p<.05) were statistically significant. In conclusion, the majority of the systemic diseases such as cardiovascular system, diabetes, and liver diseases have been considered to have relationship with periodontal disease. To strengthen oral health education is needed to enhance systemic health as well as oral health. Moreover, basic biological research should be followed to support this surveyed study.

Despite expansion of the mulnaengmyeon market, there have been no studies on consumers’ attitudes towards mulnaengmyeon. The purpose of this study was to investigate the usage and consumption patterns for mulnaengmyeon among adults in the Seoul metropolitan area of Korea. A survey including demo- and socio-graphics, general mulnaengmyeon usage, and consumption questions was tested on 210 consumers. The results of the survey showed that the majority of consumers consumed mulnaengmyeon more frequently during summer. Although the instant mulnaengmyeon market has rapidly increased, it was found that mulnaengmyeon is a food that is generally consumed in restaurants. In addition, mulnaengmyeon usage and consumption patterns significantly differed according to consumer age, whereas there was no difference observed according to parent’s or grandparent’s hometown of origin. Older consumers were observed to consume and purchase mulnaengmyeon as well as instant mulnaengmyeon more often than young consumers. Also, older consumers were shown to consider “health” related factors as more important when selecting mulnaengmyeon, whereas young consumers considered “price” related factors to be more important.

According to Multiple logistic regression analysis, gender (odds ratio 1.24, p<.05), alcohol intake (odds ratio 1.25, p<.05), cardiovascular diseases (odds ratio 1.56, p<.05), and liver cirrhosis (odds ratio 1.17, p<.05) were related to the prevalence of periodontal diseases. In conclusion, the systemic diseases such as cardiovascular system, diabetes, and liver diseases revealed to have relationship with periodontal disease. To strengthen oral health education is needed to enhance systemic health as well as oral health. Moreover, basic biological research should be followed to support this surveyed study.

The purpose of this study was to investigate the perception of health functional foods and preference for desired onion peel products. Questionnaires were distributed to 582 adults (34.2% male, 65.8% female) living in Gyeongnam province. The major information sources on biological effects of onions cited by respondents were TV/radio (37.1%), followed by nearby people (32.8%) and Internet (11.0%), in that order. Reducing cholesterol effect was the most important factor in terms of perception and concerns relating to biological function of onions. Over 73% of subjects had experience of eating processed onion products, and among all types of onion products, onion juice (53.5%) was the most frequently eaten. The most considered factors for processing onion peel-derived functional foods were taste & odor (29.6%), convenience of eating (28.9%), and nutrition value (27.1%), in that order.

Helicoverpa armigera is a serious polyphagous pest inflicting losses to various kinds of food crops. Among dis-infestation methods, methyl bromide (MeBr) has been widely used in quarantine treatments. However, after regulation as ozone depleting substance, MeBr is restricted in use. Phytosanitary irradiation has been suggested as an useful alternative to MeBr. In this study, H. armigera adults were irradiated with 400 Gy which was decided as a critical dose to the adults by the preliminary experiments. The irradiated females and males were mated reciprocally with fresh ones. Some of the both sexes were subjected to comet assay to determine the degree of DNA damage by gamma ray irradiation. There was no significant difference in fecundity among mates. However the irradiation significantly affected hatchability of F1 eggs. No F1 eggs hatched in the mate of treated female (TF) x treated male (TM). Hatchability of F1 eggs from TF x UM (untreated male) and UF x TM mates were 0.3% and 1.1%, respectively. A few larvae from UF x TM mate developed up to adults. Comet assay indicated that gamma-ray irradiation is efficient in damaging male's DNA than female's which may be the cause of dramatic decrease in F1 hatchability.

The purpose of this study was to investigate the relationship the quality of life, osteoarthritis and osteoporosis in the Republic of Korea. This study was utilized raw data from the 2010 KCHS. In total, 229,229 individuals participated in the 2010 survey. The final analysis was identified 22,545 individuals who had been diagnosed by a doctor with arthritis or osteoporosis. To identify the relationship between the quality of life - related after treated or treating of arthritis, osteoporosis, A multiple linear regression analysis was performed. Treating group for osteoarthritis of their quality of life has statistically been less than after treated group(B=-.068, p<.001). Treating group for osteoporosis of their quality of life has statistically been less than after treated group(B=-.083, p<.001). Non-treatment group who was diagnosed by doctor, but no treated subject for osteoarthritis of their quality of life has statistically been less than after treated group(B=-.075, p<.001). Non-treatment group that was diagnosed by doctor, but no treated subject for osteoporosis of their quality of life has statistically been less than after treated group(B=-.045, p<.001). Non-treatment group who was diagnosed by doctor, but no treated subject for osteoporosis and arthritis of their quality of life has statistically been less than after treated group(B=-.0121, p<.001). as a result of those data, we understand that the decision maker for treatment has been chosen by quality of life, including pain, mobility activity and so on.

담배가루이, Bemisia tabaci는 바이러스병의 매개로 인해 제주지역 시설재배 토마토에서 가장 중요한 해충으로 인식되고 있다. 황색끈끈이 트랩을 이용한 담배가루이 성충의 실용적인 발생밀도 추정방법을 개발하기 위하여 2011과 2012년 제주 서부지역의 농가재배 토마토 포장에서 포장 상황에 따라 20～30개의 트랩을 설치하여 7～10일 간격으로 조사하였다. 황색끈끈이트랩을 지상 60 cm 높이에 수평방향으로 설치한 것 이 작물 상단 10 cm 위에 수직으로 설치한 것보다 더 많은 담배가루이가 유인되었다. 황색끈끈이트랩에 유인된 담배가루이 성충의 분포형태를 Taylor’s power law (TPL)과 Iwao’s patchiness regression (IPR)을 이용 분석한 결과 두 회귀식의 기울기값이 모두 “1”보다 커 담배가루이 성충이 집중분포를 하고 있었다. TPL의 결정계수(r 2 )값이 IPR보다 더 높아 TPL이 담배가루이 성충의 공간분포 특성을 더 잘 설명하고 있었다. 담배가루이 성충 밀도를 추정하는데 필요한 황색끈끈이트랩의 수를 TPL 상수를 이용하여 추정하였는데 정확도 수준이 높을수록, 평균밀도가 낮 을수록 필요한 트랩수는 증가하는 경향이었다. TPL 상수를 이용하여 고정 정확도 수준에서 조사를 중지하더라도 트랩당 평균밀도를 추정이 가 능한 누적밀도를 계산하였다. 담배가루이 성충의 방제시기를 트랩 최고 밀도 10마리로 가정했을 때 이 밀도에서 필요한 포장당 트랩수는 고정정 확도 0.25수준에서 15개이었다. 담배가루이 성충의 트랩당 평균밀도는 트랩마다 모든 성충수를 계수하는 것보다 2마리 이상 유인된 트랩의 비율 을 가지고 추정하는 이항모델 [ln(m) = 1.19 + 0.90 ln(-ln(1-pT))]을 이용하는 것이 더 효율적이었다. 본 연구결과는 담배가루이 성충에 대한 정 확한 방제의사 결정을 통해 담배가루이가 매개하는 바이러스병 확산을 막는데 일조할 것으로 기대된다.

목 적: 성인과 아동에서 굴절이상 정도와 안광학 상수 간에 상관성이 감소하는 시점을 알아보고자 하였 다. 방 법: 청주에 거주하는 194명(성인 116명, 아동 78명)을 대상으로 자동굴절력계와 안구계측기로 굴절검 사와 안광학 상수를 측정하였다. 각막곡률반경과 전안방 깊이는 전안부 안광학 상수로, 안축장은 후안부 안 광학 상수로 이용하였다. 전안부와 후안부의 통합된 안광학 상수인 안축장 대 각막곡률반경의 비(AL/CR ratio)와 굴절이상 정도의 관련성을 제시하였다. 각 안광학 상수와 굴절이상 정도와의 관련성을 확인한 후 안축장에 따라 안광학 상수 간의 상관성이 없어지는 값을 찾고, 이를 등가구면굴절력으로 제시하였다. 결 과: 성인과 아동에서 굴절이상 정도와 안광학 상수들 간의 상관관계는 안축장과 각막곡률반경을 각각 적용하였을 때 보다 안축장 대 각막곡률반경비(AL/CR ratio)로 나타날 때 설명력이 높았다(아동 그룹 r2=0.681, p=0.000, 성인 그룹 r2=0.723, p=0.000). 성인과 아동에서 전안부와 후안부의 안광학 상수 사이 에 상관성이 없어지는 안축장의 길이를 찾았다. 아동에서 각막곡률반경과 안축장의 상관성은 안축장 24 mm 를 기준으로(r=-0.174, p=0.238), 전안방 깊이와 안축장은 25 mm를 기준으로(r=-0.153, p=0.585) 안축장 이 길어질 때 상관성이 없어지는 것으로 나타났다. 성인에서 각막곡률반경과 안축장의 상관성은 24.5 mm를 기준으로, 전안방 깊이와 안축장은 26.0 mm를 기준으로 안축장이 길어질 때 상관성이 없어지는 것으로 나 타났다(r=0.178, p=0.083, r=0.054, p=0.796). 기준점이 되는 각 안축장 값을 등가구면굴절력으로 나타냈 을 때 아동에서 24 mm는 약 -1.30D, 25 mm가 약 -3.20D로 나타났고(r2=0.609) 성인에서 안축장 24.5 mm가 약 -2.10D, 26 mm가 약 –4.30D로 나타났다(r2=0.450). 결 론 안광학 상수 간의 상관성은 정시를 벗어나 어느 정도 비정시가 된다 하더라도 지속적인 상관관계 를 나타낸다. 따라서 정시화는 특정 나이나 시력에 대한 기존의 기준과 더불어 지속적 연구를 통해 안광학 상수 간의 상관성 유무에 대한 고려도 함께 이루어져야 할 것이다.

The purpose of this study was to evaluate dietary habit and nutritional status by household income in female adults, using data from the 4th Korea National Health and Nutrition Examination Survey (2007~2009). Subjects were 8,356 women over the age of 20 years. The subjects were classified into 4 groups by household income level. Dietary data from 24 hr recall methods were used to analyze nutritional status. The obesity rate of the low income group was significantly higher than the rates of other income groups. Additionally, the nutritional status of the low income group was worse than those of other groups. The percentage of carbohydrate in total energy intake was higher and food security status was lower in the low income group than in other groups. Awareness and adherence to dietary guidelines were also lower in the low income group. Adherence to a dietary guideline of ‘avoiding salty foods and trying to eat foods with bland taste’ and ‘eating a variety of foods from each food group’ were lower than those of other groups. However, the frequency of skipping breakfast among the low income group was lower than that of others. Therefore, this study suggested that low income women should decrease the percentage of carbohydrate in total energy intake and adhere to dietary guidelines, especially those of avoiding salty foods and eating a variety of food groups, in order to improve their nutritional status.

This paper aims to contribute to the existing literature about social influence on products purchase intention. Specifically, it focuses on social influence among young adults’ purchase intention for luxury products, through investigation about Macau young adults consumption culture. Three types of social influence (informational influence, utilitarian influence, and value-expressive influence) are examined in this study. In terms of product conspicuousness, two types of luxury products can be identified based on the degree to which products usage is performed in public versus private. Hypotheses include that informational influence, utilitarian influence, and value-expressive influence will be significantly and positively related to consumer purchase intention for luxury products, both publicly and privately consumed. A convenient sample of 120 Macau young adults aged 18 to 24 participated in this study. The result of Regression and Analysis of Variance indicated that consumers have been affected by different types of social influence when they purchase different types of luxury products. Value-expressive influence is significantly and positively related to purchase intention for public products. Moreover, both informational influence and value-expressive influence are significantly and positively related to purchase intention for private luxury products. However, the effects of utilitarian influence are insignificant to both public and private luxury products, which are contrary to the hypotheses specified in this study and surprising findings about contemporary Chinese culture. Additionally, female has higher intention to buy luxury products. Based on the results of this study, marketing implications and managerial insights in the luxury retail market are recommended accordingly. Future research can provide a more comprehensive perspective of social influence than the exploratory one offered in the present study.

The purpose of this study was to evaluate dietary intake according to the risk of coronary heart disease (less than 10% = low-risk group; 10~20% = middle-risk group) based on Framingham risk score (FRS), on 122 male adult subjects. The body weight and body mass index were not significantly different between the groups, while height of the low-risk group was shown to be significantly high compared to that of the middle-risk group. The daily energy intake was shown to be significantly high in the low-risk group with 1,910.88 kcal, compared to 1,606.63 kcal of the middle-risk group. As a result of analyzing nutrient intake per 1,000 kcal of energy, while the low-risk group had significantly high intake of animal protein, fat, and animal fat compared to the middle-risk group, the intake of plant protein, carbohydrate, and plant iron was found to be significantly low. The daily food intake was shown to be significantly high in the low-risk group (1,445.16 g), compared to the middle-risk group (1,075.12 g). The low-risk group was found to have significantly high intake of sugars, eggs, and beverages compared to the middle-risk group, while mushrooms intake was significantly high in the middle-risk group. Dietary variety score (DVS) was significantly high in the low-risk group with 26.42, compared to 22.66 of the middle-risk group. Dietary diversity score (DDS) was indicated to be significantly high in the low-risk group with 3.70, compared to 3.27 of the middle-risk group. The low-risk group was indicated to have significantly high score in DDS of dairy products and fruit group, compared to the middle-risk group. In the correlation between diversity index of food intake (DVS and DDS) and FRS, DDS was shown to have significantly negatively correlation with FRS after adjusting for confounding factors. To sum up these results, the adult males with low-risk of coronary heart disease had more various consumptions of fruits and milk, compared to the subjects with the middle-risk. The proportion of consuming major food groups such as cereals, meat group, milk, fruits, and vegetables more than a fixed quantity was indicated to be high. Accordingly, dietary habit for intake of various food seems to be necessary, to prevent coronary heart disease.
