Eating alone has recently become a very common dietary pattern in modern society. This study investigated the relationship between the frequency of eating alone and health related issues including chronic diseases, depression, and the quality of life (QOL). The 2016 Korea National Health and Nutrition Examination Survey provided the basic data for this study. According to the general analysis of 4,910 adults aged over 19 years or older, the average age in the 'eating alone' group was significantly higher (P<0.001), and the ratio of single-person households was significantly higher as the number of times of eating alone increased (P<0.001). Analysis of the relationship between the risk factors of metabolic syndrome according to the number of times eating alone, using logistic regression analysis, showed that the odds ratio of metabolic syndrome in the 'two times eating alone a day' group was approximately 1.3 times higher (OR=1.275) after being corrected for gender, age and energy intake. For the 'three times eating alone a day' group, the metabolic syndrome odds ratio was higher in all models except for model 1 and 5 (P for trend<0.05). The prevalence of depression using patient health questionnaire-9 (PHQ-9) was higher as the number of eating alone increased, and the QOL was inversly related with the number of meals eating alone (P for trend<0.01). We hope the results of this study will raise awareness of the health of those people who eat alone and lay the groundwork for individuals who eat alone and gain social attention.

With changing systems of wealth creation around the 21st century, crafts(traditional and industrial crafts) are affected by the trend of changes or lead the trend, that is to say, a turning point of paradigm has come. Values of crafts give the value of users, and the tradition and modern coexists in the trend of times changing from the tradition to the modern so crafts artists’ works are diversified and used in design industries. Based on a place of expression showing various beauty of crafts, identity of design is established through ‘Craft Consilience’ of intangible cultural assets, master craftsman, crafts artists, crafts industries, and crafts departments. As master craftsman and furniture designers meet together to mix master craftsman’s idea with designers’ idea, the new Korean crafts furniture is suggested.

This study analyzes a language network of Science and Technology Basic Plan, which is the basis for science and technology policy in Korea, for the next Science and Technology Basic Plan. Language network analysis was adopted for a quantitative approach measuring the trend of policies. Several techniques such as keyword analysis, language network map analysis, quantitative characteristics analysis and keyword-related major-word analysis have been performed. Results show that there are common policies emphasized by all Science and Technology Basic Plans in the past, and there are also specific policies emphasized in each period of the Science and Technology Basic Plan. These specific policies come from a 'change of times' when the Science and Technology Basic Plans were established, as well as the philosophy of the national government.

This study has objectives of to estimate the genetic and phenotypic trend for growth in a closed herd of Landrace $\times$ desi crossbreds. The possibility of early selection of boars was also investigated in order to reduce generation interval and thus, to enhance response per year in selection programmes. The data originated from Livestock Production Research (Pigs), Indian Veterinary Research Institute (IVRI), Izatnagar (UP), India - a unit of All India Coordinated research Project on Pigs (AICRP on Pigs). Data consisted of 891 crossbred piglets, progeny of 29 boars. The piglets were born in 132 parities of 72 sows between 8 years from 1987 to 1994. Records on weight at birth, at 2 weeks interval upto 8 weeks of age (Wl, W2, ${\cdots}\;{\cdots}$ W8) and at 16th week (W16) were used in this investigation. BLLTP estimates of the sires were computed. Breeding value of each sire was estimated as twice of sire and sire group solutions. Phenotypic trend was estimated as regression of weight performance on year. Genetic trend was computed by estimating regression of breeding value of sires on time. Average body weights ranged from 0.92 kg (W1) to 18.95 kg (W16) and showed a continuous increase over age. Heritabilities of the weight at 4th and 6th week were medium (0.29 and 0.14). Rest of the weights were highly heritable. The product moment and rank, both correlations were high between breeding value for W6 and W16 (0.68 and 0.70). This shows that sire selection for W6 can be successfully implemented in order to achieve sufficient genetic improvement in growth. Phenotypic trend was positive at all ages. The phenotypic regression coefficient ranged from 0.02 kg at birth to 0.40 kg at 16 weeks. Genetic trend was also positive. The regression coefficients of average breeding value of sires on time showed a range of 1.471 kg (0.021 to 1.492 kg) for different weights. These coefficients were significant and higher than their corresponding phenotypic regression coefficient.

In this paper, trends of the widely used stability indices (SIs) and environmental parameters (EPs) were examined by using the 30-year routine rawinsonde data observed in three upper air observatories (Osan, Gwangju and Pohang) over South Korea. To take into account of the contribution of water vapor to a parcel density, we applied the virtual temperature correction in calculating the SIs and EPs. The trends of SIs and EPs indicated significant increases of temperature and moisture contents, especially at the low-to-mid troposphere during the last 10 years. The warming trend in the lower troposphere shows about 3 times greater than that of the global average (+0.10- $+0.20^{\circ}C$/10 years), whereas the cooling trend of lower stratosphere demonstrates a similar trend with the global average (-0.33- $-0.60^{\circ}C$/10 years). The vertical stability is clearly reduced due to the unsymmetrical change of atmospheric elements. The unstabilizing trend with the increased moisture contents gradually changed the atmospheric environment in South Korea into the conditions favorable for the occurrence of severe weather or intensifications of such events. These trends are consistent with the recent observations, which showed clear increase in the intensity and frequency of heavy rainfalls.

As a mirror of its time, fashion exactly reflects the trend of today' s society. In addition, as a tool to satisfy our desire and express images, it brings diverse image changes in people's minds. This kind of pattern is frequently found in wedding images, especially in wedding dresses. When it comes to a wedding dress, in general, we often think of a modest and pure-white one. In modem times, however, people prefer a differentiated image which reflects their personality and ego. In other words, it is an important means of expressing their own personality by focusing on their active and personal aspects and getting away from the passive, stable and formative aspects in the past. These days, a combination of narcissism and eroticism is found on wedding dresses. This kind of trend has been expressed into romanticism. In terms of the latest sensitive wedding dress trend, unique and creative couture wedding dresses have appeared. Therefore, this study has classified this kind of trend into two categories; Formative and Design aspects. According to an analysis on the formative and design aspects of romanticism in wedding dresses, diverse characteristics were observed in shape, color, material and ornament in the Formative Aspect. In terms of design, the characteristics of sensuality, ornament, exoticism and compromise were observed.
