This study examined the subcomponents of the local environment that have an important influence on the life satisfaction of people living in single-person households and analyzed how the causal relationship between these variables differs between generations. Specifically, the local environment was classified into the following subcomponents: convenience, comfort, safety, healthcare, and neighborhood relationships. This study analyzed the data of 3,260 respondents from single-person households in the 2020 Residents' Quality of Life Survey in Gyeonggi Province. As a result, it was found that the perception of all subcomponents of the local environment had a positive effect on the life satisfaction of people in single-person households. The effect of neighborhood relationships was relatively large compared to other subcomponents. Next, the influencing factors on life satisfaction of people in single-person households showed differences between generations, which were defined by this study as youth (under age 35), middle-aged (35-64), and elderly (65 and older). Convenience and safety for the youth group and neighborhood relationship for the middle-aged group were most important. The elderly group was most affected by healthcare. The proportion of single-person households worldwide, including in Korea, is gradually increasing, and considering this, this study provides important policy implications.

In order to survey residual characteristics of pesticides in the agricultural products selling at markets and to assess their safety, a total of 120 agricultural products were collected from the wholesale and traditional markets in Cheongju and analyzed the pesticide residues in them by multiresidue analysis method using GLC, HPLC and GC-MSD. Three pesticides, procymidone, penconazole, and tetraconazole, were detected from 4 samples such as onion, leek, tomato, and green pepper. Fungicide penconazole was detected from the onion collected from wholesale market. Fungicide procymidone was detected from leek and tomato and fungicide tetraconazole was detected from green pepper. Pesticide residues were detected from 3.3% of the total samples. The estimated daily intakes (EDIs) of the pesticides detected were less than 0.1% of their acceptable daily intakes (ADIs), representing that residue levels of the pesticides detected were evaluated as safe.

This study evaluated the effects of rehabilitation of existing coal mining spoils on species composition and species diversity. The species composition of most rehabilitated stands differed from that of the reference stands, and thus did not suggest successful rehabilitation. However, stands subjected to restorative treatment many years ago showed higher species diversity than the reference stands and thereby met the goals of rehabilitation. Our results demonstrate that restorative treatments practiced in the past created a heterogeneous ecological space with regard to the surrounding areas. Therefore, even though species diversity increased several years after rehabilitation, this does not indicate that the treatment achieved true rehabilitation success. The treatment did result in temporary stability through increased species diversity, but it could not be described as successful rehabilitation in terms of biological integrity with the surrounding ecosystems.

Melanose, caused by Diaporthe citri, is one of severe diseases in citrus, a major economic resource in Jeju island. To reduce the usage amount of organic synthetic fungicide, bio-sulfur was tested as an alternative chemical to control citrus melanose in the present study. Direct antifungal activity of bio-sulfur against D. citri was determined through in vitro experiment using artificial nutrient media. Disease severity of melanose on bio-sulfur pretreated citrus leaves was lower than that on untreated ones. To illustrate the mechanism of disease suppression by bio-sulfur, infection structures were observed with a fluorescent microscope and a scanning electron microscope. In fluorescent microscopic observation, most conidia rarely germinated. In addition, hyphal growth on leaves pretreated with bio-sulfur was inhibited compared to that on untreated ones. In scanning electron microscope images of bio-sulfur pretreated leaves, surfaces of most conidia were shrunk while hyphae were morphologically changed and frequently branched. Such microscopic observations were also found for leaves pretreated with a commercial fungicide Dithianon. These results suggest that bio-sulfur may be used to control citrus melanose as an environment friendly alternative to organic synthetic fungicides

Thermal stress of pigs causes decreased feed consumption and weight gain rate, immunosuppression, reproductive disorders, and increased mortality. The concept of the temperature-humidity index (THI) has been widely used to evaluate the degree of thermal stress of pigs. However, use of this concept is strongly restricted for animals living in the enclosed facilities. In this study, Building Energy Simulation (BES) technique was used to realize the energy flow among outside weather conditions, building materials, and animals. Especially, mechanisms of sensible and latent heat generation from pigs according to surrounding air temperature and their weight were designed to accurately evaluate the THI values inside the pig house. The THI values computed by the BES model were compared to those calculated by method of the report (NIAS, 2016), the model of this study predicted the start date of heat stress about 9~76 days earlier compared to the NIAS model. Results of the BES model also showed higher frequencies of the THI above the THI threshold for pigs, indicating that conventional model has a possibility of underestimating the degree of heat stress of pigs.

In the 21st century when people're pursuing the qualitative improvement of life, the concern about the quality of housing is growing as living standards have been improved and the desire for life has been various. Life satisfaction can be found that basic needs of residential satisfaction have been met in life, and the quality of life will be higher with the fulfillment of these desires. Humans all live in social relations, which have a big impact on the quality of life of individuals in a variety of aspects. Thus, this researcher tried to investigate middle-aged people's residential environment and the actual situation of social capital and to examine the effect of social capital on the relationship between residential environment satisfaction and life satisfaction through an empirical study. The survey was conducted for middle-aged people to collect data, 500 copies of a questionnaire were distributed and 490 of them were collected, and then the actual analysis of 484 copies without missing values was done using SPSS Ver. 21.0. As a result, first, middle-aged people's residential environment had a significant effect on life satisfaction. Second, moderating effects of social capital between middle-aged people's residential environment satisfaction and life satisfaction showed a partly significant influence. Depending on these results, the researcher try to offer the direction for the improvement of the quality of life to middle-aged people and useful data to establish Korea housing policy.

This study was conducted to evaluate the effect of phosphorus acid (H₃PO₃) addition to the horticultural bed soil on the initial growth of red pepper (Capsicum annuum L. cv.), cucumber (Cucumis sativus L. cv.), and kimchi cabbage (Brassica campestris L. ssp. pekinensis (Lour.) Rupr. cv.). The stem heights of red pepper and cucumber were 46.1% and 23.0% greater in the 50 mg/L of phosphorus acid treatment than the untreated (control). Further, the stem diameter of pepper and cucumber were 48.7% and 23.0% greater in the 50 mg/L of phosphorus acid treatment than the control. In addition, the number of kimchi cabbage leaves was 47.5% greater in the 50 mg/L of phosphorus acid treatment than the control. The dry weights of red pepper, cucumber and kimchi cabbage were 72.9%, 16.5%, and 30.4% heavier in the 50 mg/L than the control, respectively. Cations (K, Ca, and Mg) and total phosphorus (T - P) were quantitatively analyzed for these three horticultural crops. The concentrations of K, Ca, and Mg, and T - P were higher in the 50 mg/L of phosphorus acid than the control, respectively. Based on the results obtained in this study, it appears that treatment of phosphorus acid in horticultural bed soil enhanced the growth of red pepper, cucumber and Kimchi cabbage.
