Industrialization and urbanization have led automobiles to transform into more than just modes of transportation; they have become daily necessities as well as extensions of living spaces where a variety of activities can be done and automotive applications of the latest information technology are accelerated. Though material abundance has increased in the modern society, the conflicts and the stress emerging from a social structure focused on competition have increased as well. Such lifestyles generate a need for personal space and media content for healing the body and the mind. This research explores the automotive application of video content with the goal of refreshing the minds of the passengers. To this end, previous studies have investigated the emotional effect of videos, focusing on the responses of diverse groups of adults (age group of 20 to 60) who frequently used automobiles, which had video displays installed in them. The results showed that watching video contents on a full window inside a car influenced the creation of positive feelings7 and emotional satisfaction. The research attempts to study the methods of providing video contents and the effects of watching them that could aid the emotional well-being of passengers, and presents the possibility of emotional satisfaction created by a convergence of cars and multimedia contents in the future.

This experiment has been carried out to establish the most effective rearing method of rice stemborer, Chilo suppressalis (Walker) on artificial diets under the aseptic condition. The results obtained were summarized as follows: 1. Semi·synthetic diet was giving better results in the weight of matured larvae (96.4mg), emerging rate$(96.7\%)$ and number of egg masses (2.6) than other diets studied. 2. Number of egg masses and hatching rate were significantly increased on the semi-synthetic diet and chemically defned diet, and it may be due to the choline chloride in the diets, 3. Rice seedling was used as a convenient food material. However, it requires more labours and causes more damages of larvae in replacement of fresh seedlings. 4. A different result in larval weight and pupation rate was observed between simplified diet no. 1 and diet added with chlorella. 5. Simplified diet resulted in low hatchability in the second generation, which may be due to the mulnutrition of the diet for adults. 6. The pupation rate was significantly decreased by infection of microorganisms on matured larvae.

Since Metcalfa pruinosa was first reported in Koera, it has continually caused damage to sweet persimmon orchard in southern part of Korea. Metcafa pruinosa exist not only in farmland but also in forest areas, and are difficult to control due to the influx of individuals from near forest. M. pruinosa has been occurred in orchard and its surroundings because of various host range. Thus, it has been difficult to decide spatial range and control time for efficient management. In this study, occurrence and dispersal pattern of M. pruinosa in persimmon orchard were surveyed using clear sticky traps, and spatial patterns were analyzed with SADIE(Spatial Analysis by Distance IndicEs), based on location information at sticky traps. Spatial association between survey time was also analyzed to identify when the spatial pattern changed. In sweet persimmon orchard, M. pruinosa mainly dispersed in mid to late May, when the first instar hatches, and in August, emerging season of adult. The first instar nymphs hatched in mid-May were randomly distributed in orchard, but distribution was changed to aggregative pattern after dispersed surroundings of orchard. Adults showed random distribution pattern after immigration to orchard again. These tendency was also observed in density change at orchard and its surroundings, and matched to actual density of M. pruinosa in sweet persimmon trees.

This study attempted to secure competitiveness in the cosmetics market and provide basic data needed to promote sales and PR after reflecting consumer demands and needs in the development of cosmeceuticals. For this, it investigated their perception regarding the ingredients and efficacies of cosmeceuticals and repurchase intention among a total of 193 adults in their 20-50s who have had prior experience of buying these types of products from an online shopping mall as the importance of cosmeceuticals is emerging. According to a survey on consumer perceptions regarding the ingredients of cosmeceuticals by gender, there was a clear difference between men and women. In particular, when asked about the ingredients of whitening cosmetics, the percentage of male respondents was as low as 30.8% with a significant difference between men and women (t=31.688,p<0.001). In addition, most consumers were very aware of the efficacies of the ingredients of cosmeceuticals on the skin. In terms of actual repurchase intention, however, a significant difference was found by gender and product type in 3 different cosmeceuticals. In other words, men were lower than women in terms of awareness of cosmeceuticals and repurchase intention. Therefore, the development of a plan which satisfies both men and women, easily labels ingredients and meets consumer needs and demands through proper pricing policy are needed during the development of cosmeceuticals.

As the paradigm of healthcare shifts from the center of treatment to the center of prevention, products and services related to disease prevention are emerging at domestic and abroad. The government considers the smart healthcare industry as a solution to healthcare problems such as an increase in the number of chronic illnesses and an increase in the burden of medical expenses. The purpose of this study is to explore the factors affecting the use of smart healthcare products and services focusing on Health Literacy and health related personal characteristics and to provide policy implications. The subjects of the questionnaire are 1,027 adults over 20 in the nation, and conducted an online survey. In addition, the factors were analyzed by decision tree method. As a result, most of the respondents(76.9%) did not have experience using Smart Healthcare products and services. However, in the Health Literacy question, there was a difference in use experience depending on the degree of difficulty in using the mass media information. Other factors were the degree of intention to use new technology, the understanding of counseling about family members and friends, and health checkups. In order to enable self-healthcare through smart healthcare products and services, the ability of consumers to explore and utilize health information from the mass media should be improved. In addition, government and enterprise efforts are needed to achieve this.

The blueberry gall midge, Dasineura oxycoccana (Johnson) (Diptera: Cecidomyiidae), is an emerging pest on cultivated blueberries in Korea. To develop a sensitive tool for monitoring this pest in blueberry orchards, we compared the attractiveness of host plant volatiles and sex pheromone to D. oxycoccana adults. We performed gas chromatography-mass spectrometry (GC-MS) analysis of solid-phase microextraction (SPME)-collected volatiles that were released from blueberry ('Darrow' cultivar). The analysis revealed two major volatiles, cinnamaldehyde and cinnamyl alcohol from flowers; and three major volatiles, β-caryophyllene, germacrene D, and α-farnesene from shoots and young fruits. In field tests conducted in Gunsan, Korea in 2019, commercialized cinnamaldehyde, cinnamyl alcohol, β-caryophyllene, and α-farnesene, used singly or in quaternary combination, were unattractive to the blueberry gall midge. However, traps baited with the known sex pheromone (2R,14R)-2,14-diacetoxyheptadecane attracted significantly more males than the treatments with plant volatiles or the control. No synergistic effect was observed between sex pheromone and plant volatiles. Male D. oxycoccana were captured in the pheromone traps from May to August, with three peaks in mid-May, late June, and late July in Gunsan blueberry fields in 2020.

The purpose of this study was to develop and examine the effectiveness of 'Coping Resources Improvement Program' designed for emerging adults experiencing psychosocial difficulties during college to work transition. Based on transition model of Scholossberg(1995), the program was developed to intervene in 4S (Situation, Self, Support, Strategy) required in the transition. Participants included 31 job applicants who are senior or above and were assigned to the experimental group (N=10), comparison group (N=10), and control group (N=11). Data to verify effectiveness were collected pre-, mid-, and post treatment. Results indicated that the level of coping resources and psychosocial difficulties in the transition changed significantly after the program and those changes were still maintained after a month in the experimental group. However, there were no statistically significant changes on job-search burnout and career-adaptability in all groups. The implication and limitation of the study and the suggestions for the future studies were discussed.

With the increasing number of social media users worldwide, cases of social media being abused to perpetrate various crimes are increasing. Specifically, drug distribution through social media is emerging as a serious social problem. Using social media channels, the curiosity of teenagers regarding drugs is stimulated through clever marketing. Further, social media easily facilitates drug purchases due to the high accessibility of drug sellers and consumers. Among various social media platforms, we focused on Instagram, which is the most used social media platform by young adults aged 19 to 24 years in South Korea. We collected four types of information, including profile photos, introductions, posts in the form of images, and posts in the form of texts on Instagram; then, we analyzed the similarity among each type of collected information. The profile photos and posts in the form of image were analyzed for similarity based on the SSIM(Structural Simplicity Index Measure), while introductions and posts in the form of text were analyzed for similarity using Jaccard and Cosine similarity techniques. Through the similarity analysis, the similarity among various accounts for each collected information type was measured, and accounts with similarity above the significance level were determined as the same drug sales account. By performing logistic regression analysis on the aforementioned information types, we confirmed that except posts in image form, profile photos, introductions, and posts in the text form were valid information for tracking the same drug sales account.

The propensity to purchase babies' cosmetics is investigated and analysed for this research. The synopsis of this research paper is as follows. The first, the $68\%$ of all respondents do not how a manufacturer or brand name in the reality of variously emerging domestic and import cosmetics for babies. The second, in case of a child haying a fair, sensitive skin or atopy (atopic dermatitis), the respondents are careful in choosing babies cosmetics but in case of a child having a normal skin the older a child grows from a stage of a new-born, a baby and an infant to a primary-school child, the older its mother is, the more respondents use adults' cosmetics in common rather than use cosmetics only for babies. $7.6\%$ of respondents do not use babies' cosmetirs at ail. Especially, in using bathing goods such as a shampoo or a body cleanser, they frequently use adults' cosmetics in common. The third, the qualify is taken into the utmost consideration in purchasing babies' cosmetics. The Quality of imports is trusted and preferred better than that of domestic goods. The cost of purchasing babies cosmetics is less than 10,000 Won. consumers recognize that the price or cosmetics is rather high. The last, the improvement or babies cosmetics is 'the safety of goods', answered by $56.5\%$ of respondents. The respondents are generally not satisfied with babies' cosmetics. So, a baby's skin is threatened by a newly-built house syndrome, the increase of atopic dermatitis, etc., caused by an environmental pollutions, a change of diet and a change of residential life. Under these actual conditions, babies' cosmetics which can protect a delicate and sensitive skin of a baby should be developed immediately. Consumers should have a correct choice with precise recognition and information on a baby's skin and cosmetics and continually use the efficacious and excellent babies' cosmetics to prevent a baby from a skin irritation, and need to show a keen interest in a healthy skin of a baby.

Experiments were conducted to evaluate the efficacy of ground and foliar sprinkling of natural water for control of the pine needle gall midge, Thecodiplosis japonensis, by disturbing the reproductive behavior of adults such as copulation and oviposition. Diurnal ground spray for whole area application and foliar spray for single tree treatment were tested at day time during the period of adult emergence. The results obtained are as follows : 1. The population density of overwintering larvae in soil was not affected by the water spray during the adult emergence period. 2. Spraying the water showed no effect on the whole period and number of adult emergence, but retarded early emergence and facilitated Late emergence. The difference in the emerging time by 50% emergence day was approximately 7 days. 3. Ground spray was significantly different from control in gall formation rates but was not sufficient for effective control. As a single-tree treatment, the foliar spray was found to be highly effective for control of the pine needle gall midge, Average gall formation of spray plots and untreated ones were 2.6% and 38%, respectively ; control value exceeded 90%. 4. Ground spray of water was not effective in reducing larvae in gall of needle. Foliar spray, however, reduced 45% of larval numbers. 5. Foliar spray accelerated shoot growth by 15%-18%. 6. Foliar spray was highly effective for the control of sucking insects, such as mites and aphids on pine trees.
