  • Purpose: This study examined the dietary behavior, health status and nutrient intake by considering the level of household income of elderly people using data obtained from the Korea National Health and Nutrition Survey (KNHANES VII) 2018. Methods: The study subjects were 1,355 elderly people over 65 years old (558 men, 797 women). Based on their household income, participants were classified into three groups: low-income, middle-income, and high-income. The variables consisted of general characteristics, dietary behavior, health status, health related behavior, and dietary intakes. Dietary data were estimated by the 24-hour dietary recall. Results: In men, the low-income group encompassed older, less educated, less employed, and living with family of first generation. However, in women, there were no differences in employment by the level of income, and women living alone had lower income than subjects living with family. Elderly men in the high-income group had a significantly higher level of nutrient intake (energy, protein, fat, phosphorous, riboflavin, niacin and vitamin C). Men in the low-income group consumed a significantly lower intake of fruits, seaweeds and eggs, including total food. Women in the low-income group had significantly less intake of protein, fat, calcium, phosphorous, iron, vitamin A, riboflavin, and niacin whereas women in the high-income group had significantly higher intake of sugar & sweet, eggs, and beverages, including total food. Conclusion: These results suggest that the level of household income is an important factor that influences food and nutrient intake in the Korean elderly. The socioeconomic status needs to be considered differently among elderly men and women when implementing food assistant programs and designing nutrition education programs.

  • Exotic species have been imported for economic purposes, but more recently, an increasing number of animals are imported as pets. With the increasing popularity of two species of turtles, Mauremys sinensis and Pseudemys concinna, the number of pet turtle owners has gradually increased since 2014. The number of turtles increased by 180 in 2017 and 281 in 2019. However, these turtle species have been abandoned to nature, owing to their long lifespans and the changes in conditions of pet owners. The two turtle species have been designated as invasive alien species (AIS) in Korea considering their ecological risks, and the Biological Diversity Act prohibits their release. The owners of Mauremys sinensis and Pseudemys concinna are required to submit the "Application for Approval of Breeding and Grace for AIS" document. In this study, the breeding conditions for the two turtle species were investigated by analyzing the information in the submitted applications for six months (e.g., the suitability of breeding facilities, number of turtles, breeding period, type of pet adoption, and local district of pet owner). A total of 614 cases were analyzed. Because only 58% of breeders provided suitable breeding conditions, breeding information and responsible pet ownership training should be offered to prevent abandonment in natural ecosystems. In addition, continuous monitoring is necessary to prepare for potential problems caused by the lack of information in many applications and the one-off licensing policy.

  • Whereas recent researches have elucidated the positive ecological roles of large wood (LW) in fishbearing channels, LW is also recognized as a negative factor of log-laden debris flows and floods in densely populated areas. However in Republic of Korea, no study has investigated longitudinal variations of LW distribution and dynamic along the stream corridor. Hence to elucidate 1) physical factors controlling longitudinal distribution of LW and 2) their effect on variation in LW load amount, we surveyed the amount of LW with respect to channel morphology in a mountain stream, originated from Mt. Ki-ryong in Inje, Gangwondo. Model selection in the Generalized Linear Model procedure revealed that number of boulder (greater than or equal to 1.0 m in diameter), bankfull channel width and their interaction were the best predictors explaining LW load volume per unit channel segment area (unit LW load). In general, boulders scattered within small mountain streams influence LW retention as flow obstructions. However, in this study, we found that the effect of the boulders vary with the channel width; that is, whereas the unit LW load in the segment with narrow channel width increased continuously with increasing boulder number, it in the segment with wide channel width did not depend on the boulder number. This should be because that, in two channels having different widths, the rates of channel widths reduced by boulders are different although boulder numbers are same. Our findings on LW load varying with physical factors (i.e., interaction of boulder number and channel width) along the stream corridor suggest understanding for longitudinal continuum of hydrogeomorphic and ecologic characteristics in stream environments, and these should be carefully applied into the erosion control works for systematic watershed management and subsequent disaster prevention.

  • This study is designed to verify the actual effect on the prevention of the elderly suicide of the integrated crisis intervention service which has been widely provided across all local communities in Gyeonggi-province focusing on the integrated crisis intervention model developed for the prevention of elderly suicide. The integrated crisis intervention model for the local communities and its manual were developed for the prevention of elderly suicide by integrating the crisis intervention theory which contains local community's integrated system approach and the stress vulnerability theory. For the analysis of the effect, the geriatric depression and suicidal ideation scale was adopted and the data was collected as follows; The data was collected from 258 people in the first preliminary test. Then, it was collected from the secondary test of 184 people after the integrated crisis intervention service was performed for 6 months. The third collection of data was made from 124 people after 2 or 3 years later using the backward tracing method. As for the analysis, the researcher used the R Statistics computing to conduct the test equating, and the vertical scaling between measuring points. Then, the researcher conducted descriptive statistics analysis and univariate analysis of variance, and performed multi-level modeling analysis using Bayesian estimation. As a result of the study, it was found out that the integrated crisis intervention model which has been developed for the elderly suicide prevention has a statistically significant effect on the reduction of elderly suicide in terms of elderly depression and suicide ideation in the follow-up measurement after the implementation of crisis intervention rather than in the first preliminary scores. The integrated crisis intervention model for the prevention of elderly suicide was found to be effective to the extent of 0.56 for the reduction of depression and 0.39 for the reduction of suicidal ideation. However, it was found out in the backward tracing test conducted 2-3 years after the first crisis intervention that the improved values returned to its original state, thus showing that the effect of the intervention is not maintained for long. Multilevel analysis was conducted to find out the factors such as the service type(professional counseling, medication, peer counseling), characteristics of the client (sex, age), the characteristics of the counselor(age, career, major) and the interaction between the characteristics of the counselor and intervention which affect depression and suicidal ideation. It was found that only medication can significantly reduce suicidal ideation and that if the counselor's major is counseling, it significantly further reduces suicidal ideation by interacting with professional counseling. Furthermore, as the characteristics of the suicide prevention experts are found to regulate the intervention effect on elderly suicide prevention in applying integrated crisis intervention model, the primary consideration should be given to the counseling ability of these experts.

  • It is a very important book about painting theory, that "Xuanhehuapu"(宣和畵譜) was wrote by Emperor Huizhong(徽宗) in Song Dynasty. Fundamental discussions and studies in the relation of socio-economical base in Song Dynasty are still more needed. And accordingly, it is necessary to advent upgraded aesthetical articles. Li xue(理?) deeply influenced upon paintings and its theories in Song Dynasty. Similarly, Taoism(道家) and Zen Buddhism(?宗) also did. But some people who have not found "Xuanhehuapu" important meaning and rich and complicated aesthetic thought, gave low and even negative valuation to it. There is rich aesthetic in "Xuanhehuapu", which is not as simple and narrow as some people imagined. It was deeply influenced by the aesthetic thought of Confucianism(Lixue 理學), Taoism(Zhuangzi 莊子) and "Zhouyi"({周易}). I will be analytical in a few aspects "Xuanhehuapu" of aesthetics thought. 1. The calligraphy and painting is one flesh. 2. learn a good lesson from painting. 3. The handicrafts(Art, 藝) and Tao(道) unify. 4. It is a Art taxology. 5. It use a new art criticism methods.

  • The contents and method of education of all Korean scholars are similar to the contents and method of education provided by Zhu Xi(朱熹), but they operated in a somewhat different way according to schools. Those who served as the first directors of Donam Seowon were Kim Gip(金集, 1574~1656), Song Joon-gil(宋浚吉, 1606~1672) and Song Si-yeol(宋時烈, 1607~1689), who were the writers of Kim Jang-saeng(金長生, 1548~1631). Donam Seowon is supposed to have weakened the status of scholarship and the activities of lectures as HwaYang Seowon and Seoksil Seowon, which principals were all the Noron(老論) scholars, grew to be the center of education institution of the Noron. Donam Seowon have not preserved the school regulations. But the way of operating system of Donam Seowon can be guessed through the letter of Song Joon-gil, who was the headmaster of the late 17th century on the whole operation of Donam Seowon. From this letter, it is assumed that the school of Donam Seowon is similar to the 'Unbyoung-Jungsa regulations' written by Lee Yi(李珥). The headmasters of Donam Seowon was the Noron scholars. And scholars of the Kim Chang-hyeop(金昌協, 1651~1708) school became headmasters more than the scholars of Kwon Sang-ha(權尙夏, 1641~1721) school. Headmasters of the Donam Seowon had served as the headmasters of HwaYang Seowon and Seoksil Seowon also. In the early days of the establishment of the Donam Seowon, the lecture activities conducted in Donam Seowon were preceded by the textbooks of Kim Jang-saeng/Song Si-yeol's teaching curriculum and neo-confucian books[i.e Sohak (小學)${\rightarrow}$Family Ritual(家禮)${\rightarrow}$Simkyong(心經)${\rightarrow}$Keunsarok(近思錄). It is assumed that the scholars of Seoksil Seowon, who was a Noron Nak-ron(洛論) scholars, gradually adopted Lee Yi's teaching curriculum[i.e, Sohak(小學)${\rightarrow}$Sasoe(四書)${\rightarrow}$Okyoung(五經)]. This lecture contents and procedure was contents and procedure of the Seoksil Seowon, established and operated by the scholars of the Kim Chang-hyeop school. Entrance qualification of Donam Seowon's did not place importance on the social status, but on scholarship and personality. The examination for a high-ranking government official was not allowed. Although the principle, students had to participate in the lecture and study(講學), they were living in Seowon, while the financial and operating of the Seowon became increasingly difficult, the students were changed to participate in the conference(講會) held twice a month while studying at their homes.

  • Few data on the epigraph from the Bal-Hae Dynasty have been reported so far. The present paper, based on an examination of the style of the epitaphic tombstones of Princess Jeong-Hye and Princess Jeong-Hyo, investigates the historical formation and characteristics of Balhae's epitaphic style and its influences on the posterior periods. The epitaphs from the Bal-Hae Dynasty have the following epigraphic characteristics and historical significances. First, Bal-Hae's epitaphs are similar to those from the Goguryeo Dynasty in the sense that they are angular in their form. Tombstones with angular head first appeared during the East Han period. During the Wi-Jin period, however, as tombstones were not allowed to be erected in front of the tomb, small-sized epitaphic tombstones were set up inside tombs. Typical tombstones from the Dang Dynasty had stone pole and square cover. Unlike those from the Dang and the Tong-Il Silla Dynasties, however, the epitaphs from Bal-Hae had angular head in their tombstone body. The Bal-Hae's angular headed tombstones are very likely to testify that Goguryeo's epitaphs, which features an influence from the Wi-Jin Nambuk-Jo period, in turn exerted an effect on those from the Bal-Hae Dynasty. Second, Bal-Hae's epitaphic tombstones are characterized by their hexagonal head,which were modified from the then typical pentagonal head by cutting out the sharp point. The hexagonal head, which has not been found in its neighboring countries during the same historical period, is peculiar to the epitaphic tombstones from the Bal-Hae Dynasty. Third, the edge lines and ornamental figures first appeared in Bal-Hae's epitaphic tombstones, as seen in those of Princess Jeong-Hye. In the fa?ade of the epitaphic tombstone, a carved line demarcates its rectangular body and trapezoidal head. Four faces of the body stonehave two parallel lines in their edges within which vignette was inscribed, and the trapezoidal head part was ornamented with flower figures. Fourth, Bal-Hae's epitaphic tombstone had an extensive influence on the posterior countries in its neighborhood. The epitaphic tombstones in the Bal-Hae style are very often found in those of the Goryeo Dynasty and the Yo Dynasty which were greatly influenced from Bal-Hae. The vestiges of Bal-Hae's epitaphic style are also found in those from the Song, the Geum, and the Won Dynasties.

  • The purpose of this study was to select a suitable planting substrate for multilayered plantings in an apartment landscape space. The experiment was conducted between May to October 2019, at the National Institute of Horticultural and Herbal Science. Planting substrate was prepared in six repetitions of eight treatment zones using mulching material, horticultural soil, bottom ash, and subgrade soil. Rosa hybrid 'Barkarole' and Hydrangea macrophylla 'Nikko Blue' were selected as the experimental plants. We investigated the monthly variation and effect of the substrate type on the growth (plant height, number of branches, leaf length, leaf width, and plant area of the substrates) of the plants. In R. hybrid 'Barkarole' grown in 20 cm of horticultural soil and 10 cm of bottom ash, the plants were taller(102.2±5.8 cm), had more branches (5.5±0.6 each), longer leaves (10.9±1.0 cm), and greater leaf width (6.2±0.5 cm) and plant area (4077.1±416.6 cm2)(p<0.05). H. macrophylla 'Nikko Blue' showed the best growth from 3cm of mulching, 20cm of horticultural topsoil, and 10cm of bottom ash, which resulted in taller plants (43.6±2.1 cm), more branches (4.9±0.8 each), longer leaves (7.2±0.5 cm), and greater leaf width(4.3±0.3 cm) and plant area (344.5±43.2 cm2). Through this study, it was possible to propose an optimal planting substrate for shrubs for multi-layered landscaping.

  • The government budget for promoting startup have been skyrocketed as catching up with increasing demands for high-tech startup by disruptive innovation resulted from rapid technology change. However, major trend of startup have still fallen on self-employed type of startup due to the lack of expertise and fund in spite of desperate government policy efforts. In reality, the access to high-tech startup has been very limited and too high huddle to would-be entrepreneur. This paper implement empirical analysis on the effects of entrepreneur competency and satisfaction level to government support, considering these as the KSF for the growth and success of high-tech startup, to the performance of the company. In particular, it focus on defining unique characteristics of high-tech startup through differential proving by the backgrounds of entrepreneur such as major, R&D experience, patent possession, CTO possession. This research carry out survey to 217 entrepreneurs in high-tech company in Daejon and Daegue at R&D Special Innopolis Zone. Research results are as follow. First, entrepreneurial achievement competencies, conceptualization competencies, network competencies and market recognition competencies positively affect the financial and non-financial performance and organizational and technical competencies, while organizational and technological competencies only positively impact on non-financial performance. Second, the satisfaction level of government support showed a positive moderating effect on entrepreneurial achievement competencies and financial performance, while no significant effect in other competencies. Third, positive differential effect by the technological background of entrepreneur such as Major, R&D experience, patent possession, CTO possession) have been confirmed. This paper deliver several significant implications and contributions, First, it propose classified and systematized entrepreneur competency through the domestic and foreign literature reviews. Second, it proves the need for the wider spread of team based startup culture rather then sole startup. Third, it also proves the important role of technological background of entrepreneur among the characteristics of high-tech startup.

  • This study aimed to evaluate preferences of Bukhansan dulegil using sentiment analysis, a natural language processing technique, to derive preferred and non-preferred factors. Therefore, we collected blog articles written in 2019 and produced sentimental scores by the derivation of positive and negative words in the texts for 21 dulegil courses. Then, content analysis was conducted to determine which factors led visitors to prefer or dislike each course. In blogs written about Bukhansan dulegil, positive words appeared in approximately 73% of the content, and the percentage of positive documents was significantly higher than that of negative documents for each course. Through this, it can be seen that visitors generally had positive sentiments toward Bukhansan dulegil. Nevertheless, according to the sentiment score analysis, all 21 dulegil courses belonged to both the preferred and non-preferred courses. Among courses, visitors preferred less difficult courses, in which they could walk without a burden, and in which various landscape elements (visual, auditory, olfactory, etc.) were harmonious yet distinct. Furthermore, they preferred courses with various landscapes and landscape sequences. Additionally, visitors appreciated the presence of viewpoints, such as observation decks, as a significant factor and preferred courses with excellent accessibility and information provisions, such as information boards. Conversely, the dissatisfaction with the dulegil courses was due to noise caused by adjacent roads, excessive urban areas, and the inequality or difficulty of the course which was primarily attributed to insufficient information on the landscape or section of the course. The results of this study can serve not only serve as a guide in national parks but also in the management of nearby forest green areas to formulate a plan to repair and improve dulegil. Further, the sentiment analysis used in this study is meaningful in that it can continuously monitor actual users' responses towards natural areas. However, since it was evaluated based on a predefined sentiment dictionary, continuous updates are needed. Additionally, since there is a tendency to share positive content rather than negative views due to the nature of social media, it is necessary to compare and review the results of analysis, such as with on-site surveys.
