  • Developmental characteristics of Geocoris pallidipennis were investigated at a constant temperature (20±1, 25±1, 30±1, 35±1, 37.5±1 and 40±1C), under long day illumination 16:8 (L:D) and constant relative humidity (80±10). From egg to adulthood, the lower developmental threshold and the effective accumulative temperature were 14.8C and 399.1 day-degree, respectively. The experimental results at 35C were as follows. The egg period was 5.6 days (hatchability: 81.1%) and the nymphal period was 14.3 days (1st: 3.2, 2nd: 2.2, 3rd: 2.7, 4th: 2.7, 5th: 3.6). Female longevity was 33.8 days and the oviposition period was 29.2 days. Total egg production was 111.2 eggs and the maximum daily egg production was 14.8 eggs (in 7th days). However, although some eggs and nymphs developed at 37.5C, G. pallidipennis could not develop at 40C, The total egg production at 40C was only 22.1 eggs. When G. pallidipennis was fed on Bemisia tabaci pupae, daily prey consumption by nymphs (1st, 3rd and 5th) and adults was 1.9, 7.3, 18.7 and 29.5, respectively.

  • The purpose of this study is to investigate the differences of the factors affecting the entry of depression by generations and to present a practical strategy for preventing of depression by life-cycle. For this purpose, we analyzed the factors influencing the depression of adults, middle-aged and elderly people through the discrete-time hazard model. The results of this study are as follows: First, the lower the self-esteem, the lower the income satisfaction and the family satisfaction people have, the higher the likelihood of entering the depression they have. In addition, age, educational level, health status, presence of chronic diseases, employment status, regional area, and leisure life satisfaction were variables that showed difference by generation. In the case of adulthood(aged 20 ~ 39), unemployed persons are more likely to enter the depression than younger workers. On the other hand, the middle-aged(40 ~ 64 year olds) are more likely to enter the depression if they are older, have poor health status, have no chronic disease, and have low leisure satisfaction. Finally, older people(aged 65 and over) are more likely to enter the depression when the education level is higher, the health condition is worse, and the leisure satisfaction is lower. If they lived in an urban and rural complex, they are more likely to enter the depression. Based on these results, it is necessary to establish a support plan reflecting the characteristics revealed by generations in order to prevent the entry of depression.

  • The colors have a close to our life and there are many color names derived from plants in Japan. This study aimed to analyze relationship people and plants and investigated what the images of colors derived from plants related to the color names. Surveys on color images of abstract and concrete were conducted with adults who lived in the metropolitan area and in urban areas. The subjects were surveyed about images of similar colors derived from plants(3 type of similar two colors; pink, green and yellow) and asked to select a pair of color names(momo or pink, midori or green, yamabuki or lemon) corresponding to the color. The subjects were simultaneously presented with two similar colors and asked to give their perceptions of each color against 13 polar opposite pairs of terms or phrases using a Semantic Differential Scale, and asked to select the number of the 16 items concerned with life such as clothes and food. With the pink colors, many subjects did not feel opposite abstract images between these two similar colors and felt the same concrete images such as 'cosmetics' and 'clothes', and these color names such as momo and pink are confused. With the green colors and the yellow colors, many subjects felt opposite abstract images between these two similar colors such as 'natural - artificial' and 'rural - urban' and different concrete images such as 'plants' and 'plastics', and these two similar colors are distinguished by the color names such as 'midori - green' and 'yamabuki - lemon'. The results revealed that there are two patterns in the relationship colors derived from plants, color images and color names. In the pattern which images of colors derived from plants are connected with artificial things irrelevant to plants, the color names corresponding to the two similar colors are confused. On the other hand, in the pattern which images of colors derived from plants are connected with plants and artificial things, the two similar colors are distinguished by their color names. So demographics influenced the images of color, younger subjects compared with older tend to obviously distinguish images of colors derived from plants, and there are images of color influenced by the environment as a child. In both patterns, images of colors derived from plants are influenced by artificial things and natural colors are limited among many people. These results indicate that there are a few opportunities to see colors of plants which are full of variety. These results suggest that it is necessary to recognize colors derived from plants in relation to plants and to educate regarding the nature of plants, therefore landscape architecture focused on colors of plants is required.

  • Objectives: Environmental, social and personal factors influence eating patterns. This study aimed to investigate the relationship between unhealthy food outlets within a residential area and obesity using nationally representative Korean survey data and data from the Census on Establishments. Methods: Data on the food intakes and socioeconomic variables of a total of 9,978 adults aged 19 years were obtained from the 2013-2014 Korea National Health and Nutrition Examination Survey. Geographic locations of restaurants were obtained from the 2013 Census on Establishments in Korea. Administrative area was categorized into tertiles of count of unhealthy food outlets based on the distribution of number of unhealthy food outlets among all urban (Dong) and rural (Eup or Myun) administrative districts in Korea. Multilevel logistic regressions model were used to assess the association between the number of unhealthy food outlets and obesity. Results: People living in the district with the highest count of unhealthy food outlets had higher intakes of fat (45.8 vs. 44.4 g/day), sodium (4,142.6 vs. 3,949.8 mg/day), and vitamin A (753.7 vs. 631.6μgRE/day) compared to those living in the district with the lowest count of unhealthy food outlets. A higher count of unhealthy food outlets was positively associated with frequent consumption of instant noodles, pizza, hamburgers and sandwiches, sweets and sour pork or pork cutlets, fried chicken, snacks, and cookies. Higher exposure to unhealthy food outlets was associated with increased odds of obesity (1st vs. 3rd tertile; OR 1.689; 95% CI 1.098-2.599). Conclusions: A high count of unhealthy food outlets within a residential area is positively associated with the prevalence of obesity in Korea. The results suggest that food environmental factors affects the health outcomes and interventions aiming to restrict the availability of unhealthy food outlets in local neighborhoods may be a useful obesity prevention strategy.

  • This study examines factors that influence older drivers to consider stopping driving in advance and whose advice plays an important role in the driving cessation decision. Data came from a nationally representative cross-sectional survey of community-dwelling older adults (N=2,076). About two thirds reported that they have considered stopping driving (62.8%) and they preferred to decide by themselves (66.0%). Logistic regression results showed that women and residents in urban areas were twice as likely to consider voluntary driving cessation compared to their counterparts. Each one year increase in age contributed to the probability that respondents would consider driving cessation by five percent. Those with greater difficulties in ADLs due to chronic illnesses were also more likely to consider driving cessation. No sociodemographic and health factors were related to whether older drivers preferred to decide by themselves or listen to others. These results imply that policies to promote self-motivation to stop driving among older drivers would be effective. Furthermore, they suggest it could be important to help older drivers plan their driving cessation in advance while still at a young-old age, and that more attention needs to be paid to men and those living in rural areas among older drivers.

  • This study has been done to understand the relationship between age norms and negative perception on older workers, and to find out moderating effect of recognition of employment welfare services in those relationships. And the purpose of this study is to suggest alternative ways to improve pessimistic perception on older workers, which is basal ageism. For this purpose, the survey has been conducted with 630 participants, who were 20 years old and over and lived in 15 different provinces. The collected data has been analysed by using SPSS Win 18.0. The results as followed: first, there were significant differences of negative perception on older workers among provinces(metropolitan areas, small towns, and rural areas); second, age norms significantly influenced on pessimistic perception on older workers; third, moderating effect of recognition of employment welfare services has been verified. These results suggest that it is necessary to promote people to take a flexible attitude toward older adults using media broadcasting and promotion of employment welfare services. Public and private cooperation should be needed to change people's negative perception on older workers. Lastly, programs, which are appropriated and tailored in specific provinces, improving awareness of older workers should be required.

  • In this study, two essential oils (EOs) extracted from Aleriana fauriei and Alpinia galangal were formulated as an emulsifiable concentrate (EC) and a granule. In the evaluation of their acute toxicity on fishes, Cyprinus carpio adults were used and the toxicities were determined in a static condition. The formulations were prepared from the essential oil extracted by three different methods namely steam distillation (SD), solvent extraction (SE) and supercritical fluid extraction (SFE). The acute toxicities were calculated using LC50 values. Among EOs, only the EO extracted by solvent showed acute toxicities on carps. Some of the EC, EOs of Aleriana fauriei did not exhibit toxicity, while EOs from Alpinia galangal showed potent acute toxicities on carps. Among the granules, granules formulated with Aleriana fauriei EO extracted by SD method and Alpinia galangal EO extracted by SFE method showed acute toxicities on fishes. Nevertheless, LC50 of ECs and granules formulated with all types of EOs in this study was higher than the fish toxicity level III for pesticides suggested by Korea Rural Development Administration. Furthermore, cytochrome P450 1A and glutathione S-transferase were confirmed as biomarkers in carps in response to the exposure to Alpinia galangal EO extracted by SD and SFE method, tracking Alpinia galangal EO in the aquatic environment.

  • Objectives: This study analyzed the decline in quality of life according to age in the chronic disease patient group, quantified it as a quantitative index, and compared it by sex and chronic disease. Methods: In the 2017-2019 Korea National Health and Nutrition Examination Survey database, 11,473 adults aged 19 years or older, excluding cancer patients, were analyzed for age-specific changes in the EQ-5D Index by chronic disease. The decline in quality of life according to age in patients with chronic diseases was analyzed by linear regression analysis while controlling for general characteristics. Then, linear regression analysis was performed according to sex. Results: In the case of the control group, the quality of life decreased by 0.0004 for every 1-year increase in age(P<0.001). By chronic disease, asthma(β=0.0019, P<0.001), arthritis(β=0.0017, P=0.002), thyroid dis- ease(β=0.0016, P=0.015), dyslipidemia(β=0.0011, P=0.020), and hypertension(β=0.0009, P=0.027) mostly showed a greater decrease in quality of life than the control group. In addition, when divided into two groups by sex, hypertension(β=0.0012, P=0.029), thyroid disease(β=0.0041, P=0.038), and arthritis(β=0.0022, P<0.001) showed a significant decrease in quality of life only in male. Diabetes(β=0.0056, P=0.038), dyslipi- demia(β=0.0022, P=0.001) significantly decreased quality of life only in female. Conclusions: Chronic disease had a negative impact on patients perception of quality of life, and the more severe the pain and activity limitation due to the chronic disease, the more severe it was. It also showed different patterns according to sex. Therefore, it is necessary to allocate more medical resources and provide policy support to prevent chronic diseases, which are serious social problems.

  • Objectives: We aim to identify factors associated with unmet dental care needs in older adults and explore the impact of time, economic and physical constraints on each. Methods: The analysis was based on the 2023 Community Health Survey. Statistical analyses were conducted using chi-square test and multinomial logistic regression for 65,952 people aged 65 years and older. Results: First, we looked whether subjects experienced unmet dental care needs and found that 8.4% did. Second, according to the type of unmet dental care needs, 54.1% of the time, economic, and physical constraints were economic constraints. Analyzing each of the time, economic, and physical constraints, we found that time constraints were associated with younger age. For economic constraints, lower education level and health security type of recipients in medical aid program were more likely to experience unmet dental care needs. In terms of physical constraints, those living in rural areas were more than three times more likely to experience unmet dental care needs than those living in urban areas. Conclusions: The results showed that time constraints were related to age, economic constraints were related to household income level, and physical constraints were related to residential area.

  • Objectives: Socioeconomic status plays an important role in health care and disease prevention. This study aimed to examine the association between socioeconomic status, measured by education levels and household income, and gastric cancer screening. Methods: A total of 21,220 community-dwelling adults aged 40 to 69 years within a defined geographic area participated in a community health survey in 2009 and 2010. The survey was conducted using a structured questionnaire by trained investigators who visited the subjects' households directly. Logistic regression analysis was used to determine the relationship between self-reported participation in gastric cancer screening and socioeconomic variables (education and household income). Results: The gastric cancer screening rate was 52.1% for subjects in their forties, 63.7% for those in their fifties, and 67.3% for those in their sixties. In multivariate analysis, higher education and income levels were associated with higher rates of gastric cancer screening (high school vs. elementary school: odds ratio [OR] 1.41, 95 % confidence interval [CI] 1.26-1.58; highest income quartile vs. lowest income quartile: OR 1.62, 95% CI 1.44-1.84). The gradient between income and screening rate was more pronounced in the population aged 40 to 49 years than in the other age groups. Conclusions: This study demonstrates that lower socioeconomic status is associated with decreased participation in gastric cancer screening. Our findings suggest that the screening program should be focused on low-income and less-educated populations, especially among younger adults, to reduce health disparities.
