The present study was carried out in order to investigate seasonal variation in tannin, sugar and protein contents of persimmon fruits, Five varieties of Diospyros kaki Thunberg, i. e, Buyoo, Wolha, Kapjubackmok, Pyungmuhek, Heuksi, and Goyom (Diospyros Lotus Linne var. typica Makino) growing in Jeonbug area were used as the experimental material. The result are summarized as follow; 1. Maximum tannin contents were 4% in Buyoo, 5.46% in Wolha, 5.4l% in Kapjubackmok, 5.1 % in Pyungmuhek, 9.2% in Heuksi, and 26.1% in Goyom, respectively. Therefore, Heuksi and Goyom were considered to be the most useful as tannin material. 2. The most suitable season for tannin extraction was thought to be July with most varieties but it was August with Goyom. 3. The total sugar contents seemed to increse linearly. Linear regressions are as follows. Buyoo ; $\hat{Y}=0.2394x+3.861$ Wolha ; $\hat{Y}=0.3093x-1.148$ Kapjubackmok ; $\hat{Y}=0.3173x-1.3708$ Pyungmuhek ; $\hat{Y}=0.2796x+0.982$ Heuksi ; $\hat{Y}=0.3233x-3.242$ Goyom ; $\hat{Y}=0.1555x-4.780$ 4. Average crude protein contents of fruits through the year were 5.32% in Buyoo, 4.97% in Kapjubackmok, 4.49% in Goyom, 4.11% in Wolha, 4.02% in Heuksi, and 3.6% in Pyungmuhek, respectively. 5. The crude protein contents tend to decrease gradually after fruit setting.

At present, the whole world is characterized by openness, cooperation and integration as a society with information and the world, and it requires creative talents for this. The competitiveness of the nation depends on the cultivation of creative talents. It demands anthropological value by improving the competitiveness of the nation through cultivating creative talents to share and care, not to cultivate creative talents for personal desires and accomplishments. The purpose of this study is to develop a teaching - learning process to develop integrated creative talents by applying the characteristics of integrated education curriculum at the base of the 2015 revised curriculum. To do this, we first extracted the content elements of the Clothing Life area of the revised curriculum from the 1st to 2015 and the contents of the Clothing Life area of the technology and home Economics textbooks to which the 2009 revision curriculum was applied. Five topics were extracted according to content selection criteria And The Theme of 'The selection and management of clothing' was selected. Researcher developed a integrated thematic instruction Home Economics Education Clothing Life teaching - learning process (hereinafter referred to as "the process") focused on the theme of 'selection and management of clothing'. The Process was composed of 5 basic classes [basic inquiry - content 1 - content 2 - depth study - application]. The process considers integration within the curriculum and interdepartmental integration, and aims to improve the personality, creativity, and problem solving ability of consideration and sharing in the course of the integrated class. In detail, the curriculum goals of the home Economics Education curriculum and ITI goals are presented separately in the curriculum developed for each process. At the stage of the class, the element of creativity and the element of personal education were exposed and applied to the class. In Korea, new curriculum has been revised and announced from time to time, making it difficult for the teacher to carry out the class in accordance with the paradigm of change. Home curriculum is closely related to real life, so it is an appropriate subject for an integrated subject. It has the educational significance of the subject in that it allows students to integrate the creative and personal elements that are limited in other subjects. ITI process will be helpful to teachers who need to implement the 2015 revised curriculum in which the theme-centered integrated home Economics education teaching-learning process is newly introduced. It is necessary to follow - up research to verify the effectiveness of how to improve students' problem - solving ability and cultivate creativity.

Purpose: Few reports have described the prognostic factors affecting the occurrence of subsequent unprovoked seizure in patients who present with febrile seizure (FS) after 6 years of age. We investigated the prognostic factors affecting the development of unprovoked seizures after FS among patients from Jeju Island. Methods: We included patients who developed FS after 6 years of age, who presented to our outpatient clinic between January, 2011 and June, 2017. Clinical data were obtained through chart reviews and phone call interviews. We used logistic regression analysis to analyze the risk factors associated with the occurrence of subsequent unprovoked seizure. Results: Of the 895 patients who presented to our hospital due to their febrile seizure, 83 developed FS after 6 years of age. Among them, 3 patients were prescribed antiepileptic drugs before the onset of the unprovoked seizure, and 4 patients developed an unprovoked seizure before 6 years of age. Thus, overall, 76 patients were included in the study. 51 patients developed first FS before 6 years of age. In the remaining patients, the first FS developed after 6 years of age. The mean observational period since the last outpatient follow-up visit was 3.2 years (median 3.04 years, range: 1.42-4.71 years). Among them, 21% developed an unprovoked seizure. Logistic regression analysis showed that electroencephalographic (EEG) abnormalities served as an independent risk factor for a subsequent unprovoked seizure. Conclusion: EEG is the proper diagnostic tool to predict the risk of a subsequent unprovoked seizure in patients with FS after 6 years of age.

With the growing importance of technology innovation as a key factor for firms' competitive advantage, 'innovation persistence' became also an important research subject. 'Innovation Persistence' is a concept that indicates whether or not firms' innovation activity or performance continues. However, the data used for innovation studies are carried out as cross-sectional surveys in most countries. For this reason, studies dealing with longitudinal aspect of innovation persistence are rare. In particular, there is almost no research on innovation persistence using Korean innovation survey data. This study reviews the concepts and characteristics of innovation persistence based on extant literature, and perform an empirical analysis on the status and features of Korean firms' technology innovation persistence. Based on the data of the Korean Innovation Survey (KIS) conducted every other year from 2012 to 2018, panel data on 3,379 firms which observed multiple times are constructed. As a result, only part of the firms with persistent innovation were observed (for innovation performance 10~12%, for innovation activity 15~17%), and it was found that the persistence of non-innovation was remarkable(about 52~57%). And it was confirmed that the persistence of innovation activities is stronger than that of innovation performance. Besides, some features by sub-types of innovation appeared. Product innovation showed higher persistence than process innovation, and internal R&D also showed higher persistence than joint/external R&D. As a result of additional logit analysis to identify factors, it was found that radical or gradual product innovation is the most influential factor in persisting innovation in the next period. Since the sample selection bias due to a limitations of raw data might exist in the panel data constructed in this study, it should be noted that faulty generalization of the results are not allowed. Nevertheless, this is the first study to examine the technology innovation persistence targeting Korean firms and is expected to be a starting point for follow-up studies. It is anticipated that advanced research results will be drawn through the establishment of official panel data and improved methodologies.

This study analyzed issues and trends related to ports with 86,611 news articles for the 30 years from 1991 to 2020, using BIGKinds, a big data news analysis service. The analysis was based on keyword analysis, word cloud, relationship diagram analysis offered by BIG Kinds. Analysis results of issues and trends on ports for the last 30 years are summarized as follows. First, during Phase 1 (1991-2000), individual ports such as Busan, Incheon, and Gwangyang ports tried to strengthen their own competitiveness. During Phase 2 (2001-2010), efforts were made on gaining more professional and specialized port management abilities by establishing the Busan Port Authority in 2004, the Incheon Port Authority in 2005, and the Ulsan Port Authority in 2007. During Phase 3 (2011-2020), the promotion of future-oriented, eco-friendly, and smart ports was major issues. Efforts to reduce particulate matters and pollutants produced from ports were accelerated, and an attempt to build a smart port driven by port automation and digitalization was also intensified. Lastly, in 2020, when the maritime sector was severely hit by the unexpected shock of the COVID-19 pandemic, a microscopic analysis of trends and issues in 2019 and 2020 was made to look into the impact the pandemic on the maritime industry. It was found that shipping and port industries experienced more drastic changes than ever while trying to prepare for a post-pandemic era as well as promoting future-oriented ports. This study made policy suggestions by analyzing port-related news articles and trends, and it is expected that based on the findings of this research, further studies on enhancing the competitiveness of ports and devising a sustainable development strategy will follow through a comparative analysis of port issues of different countries, thereby making further progress toward academic research on ports.

The purpose of this study is to examine the meaning of learning methods for education to transmit the items designated as intangible cultural heritages focusing on Seoul-gut. Recently, as the Act on the Preservation and Promotion of Intangible Cultural Heritages was promulgated, 'the archetype' instead of 'the prototype' has become highlighted as a crucial axis for transmission. Although there are some controversies over the definition of the archetype among scholars, it is now possible for transmitters to make use of transformations rather freely being freed from strict orientation to the prototype to follow some fixed frame. Examining learning methods used in education to transmit mudang-gut, one of the items designated as intangible cultural heritages, however, this author has found that the prototype is still emphasized or in the center of learning instead. Presenting learning methods employed for Hwanghaedopyeongsansonoreum-gut of a national intangible cultural heritage, Namijanggunsadang-gut of Seoul Special City's intangible cultural heritage, and Bonghwasandodang-gut as examples, this researcher intends to reveal the reality. In the recent situation that education centering around academies is being widely spread to transmit mudang-gut, setting forth the designation of some of the items as intangible cultural heritages, they are publishing articles on newspaper as an advertisement to encourage learning about mudang-gut. Responding to the advertisement, there are more and more shamans intending to learn mudang-gut coming to the society for preserving items designated as intangible cultural heritages. They can, of course, perform mudang-gut on their own but come to learn it as there is no fixed or definite system for it. Even though the concept of the archetype was introduced, as now it is possible to learn the fixed frame through learning about the prototype regarding the item of mudang-gut as an intangible cultural heritage, those involved in shamanism are coming to it more and more. As transmitting the prototype rather deteriorated the liveliness of gut, those involved in shamanism are coming to it to learn about gut thinking that it is where they can learn the basic frame and also acquire more detailed knowledge about shamanism. Therefore, it is needed for the item of mudang-gut designated as an intangible cultural heritage to accept the aspects of change and develop new methods of education to transmit intangible cultural heritages.

The two school $M{\bar{a}}dhyamika$ and $Yog{\bar{a}}c{\bar{a}}ra$ act as a representative of $Mah{\bar{a}}y{\bar{a}}na$ Buddhism in India. But the two school disputed with each other insisting ${\acute{s}}{\bar{u}}nyat{\bar{a}}-v{\bar{a}}da$ and $vij{\tilde{n}}aptim{\bar{a}}trav{\bar{a}}da$ separately. To introduce the disputation shortly is as follow. $N{\bar{a}}g{\bar{a}}rjuna$ explained the world and truth by two truth theories(二諦說) which carry out truth of a word and the dimension(spiritual enlightenment) which is absolute(ultimate) to it being lokasaṁvṛtisatya(世俗諦) about the truth which can be expressed verbally, and which is phenomenon-like (everyday) at paramaarthasatya(勝義諦). By the way, lokasaṁvṛtisatya and paramaarthasatya are actually distinction of the recognition which is not an ontological distinction. That is, lokasaṁvṛti(世俗) is paramaartha(勝義) as it is the time of seeing by the eyes of those who have realized. The two truth theories of $N{\bar{a}}g{\bar{a}}rjuna$ was developed logical more precisely by his successors. With an everyday language, the position of Candrakīrti(月稱) that it cannot be expressed as the position of $Bh{\bar{a}}vaviveka$(淸辨) that paramaarthasatya can be expressed logically is opposed to each other, and dissociates by $Sv{\bar{a}}tantrika$(自立論證派) and $P{\bar{a}}rsagika$(歸謬論證派). Confrontation of $Sv{\bar{a}}tantrika$ and $P{\bar{a}}rsagika$ is the dispute about the ability of s which is the highest truth to be proved logically. The $P{\bar{a}}rsaga$ of Candrakirti thinks that people exist truly, and is because it claims not existing in the world where a favorite thing is actually actual. However, $Bh{\bar{a}}vaviveka$ proved Sunyata(空性)을 positively based on the reliance to language and logic. Also the mokṣa of $M{\bar{a}}dhyamika$ is not recovery of original condition of $vij{\tilde{n}}apti$ which is pure in itself as $Yog{\bar{a}}c{\bar{a}}ra$ saying, as well as obtaining a thing which is dravya-sat as $Sarv{\bar{a}}stiv{\bar{a}}din$ saying. The mokṣa of $M{\bar{a}}dhyamika$ means a condition of liberated from karma and pains through extinction of $prapa{\tilde{n}}ca$ and discrimination by realizing the real aspect of all dharma which is said by pratītyasamutpāda, $praj{\tilde{n}}apti$, niḥsvabhāva, ${\acute{s}}{\bar{u}}nya$, $madhyam{\bar{a}}pratipad$.

The vocational competency development training teacher must complete the training course for the training of vocational competency development training instructor and get the qualification of the vocational competency development training teacher from the Ministry of Employment & Labor with the criteria set by the Presidential Decree. Therefore, it can be said that H_university 's educational performance, which is the only vocational competency development training teacher in Korea and that plays a role of mass production in the labor market, has a great influence on vocational competency development training. The purpose of this study is to identify the problems through the analysis of actual condition of vocational competency development training education based on CIPP model, Furthermore, it was aimed to suggest improvement plan of qualification training education. In order to accomplish the purpose of the research, the present situation of the training course for the vocational competency development training teacher training students was grasped. And We conducted a survey to draw out the improvement plan and utilized the results of 173 copies. We conducted interviews by selecting eight subjects for in-depth analysis and Understand the details of the results of the surveys conducted. As a result of the study, positive responses were obtained from the educational objectives and educational resources in the context factors. On the other hand, there were negative opinions about the curriculum reflecting the learner and social needs. In the input factors, positive opinions were derived from the educational objectives and training requirements. However, there were many negative opinions about the achievement of the learner's educational goals. In addition, there were many negative opinions of online contents education. In the process factors, positive evaluation was high in class related part, learner attendance management, and institutional support. However, negative opinions were drawn on the comprehensive evaluation of qualification training period, and the learner's burden due to lack of learning period appeared to be the main reason. In the factor of calculation, Positive opinions were derived from the applicability of the business curriculum for training courses for training teachers who are in charge of education and training in industry occupations. However, there were negative opinions such as learning time, concentration of learning, and communication of instructors. Based on the results of the study, suggestions for improving the operation of vocational competency training teacher qualification training are as follows. First, it is necessary to flexibly manage the training schedule for the weekly training course for vocational competency development training teachers. Second, it is necessary to seek to improve the online education curriculum centered on consumers. Third, it is necessary to seek access to qualification training for local residents. Fourth, pre - education support for qualified applicants is required. Finally, follow-up care of qualified trainees is necessary.

Under the global economic competition, company competitiveness depends on creating high performance through effective human development. It is also a tendency to analyze organization members'competencies and outcomes, develop competency model, and apply the model to developing and managing human resource in each organization. Therefore, this study figures out the present condition of development of competency model and its application to examine the degree to which the competency model, which has been introduced to Korean companies for the use of competency diagnosis of members, is being utilized. For this purpose, survey items were created by expert council and advisory committee and survey was conducted for Korean corporations. The result shows that most of the companies, regardless of size and type, develop their own model by referring to outside models, or use models developed by consulting company lead. Therefore, it is urgent for the companies to develop model appropriate for the peculiarity of each company. Second, while the main reason to introduce competency model was to reinforce workers' competency, models developed have not widely utilized in HRM overall. There is a need to overcome a limit of utilization of models. Third, Majority responded that they, regardless of size and type, upgraded models or did not upgrade at all due to change of work environment. There is also a need to systematize follow-up care of the models. This is a primary research to examine the present condition of development of competency model and its application in company so that it can be used as springboard to study in-depth inside condition of Korean company using competency model and condition of particular positions of company members.

This study has researched the characteristics and elements of Chwibyeong (翠屛), a sort of trellis in the Joseon Dynasty through the old documents, and the original form of Chwibyeong at Juhapru (宙合樓) in Changdeuk Palace. The results were as follow. First, as the result of literatures analysis for Imwon-gyeongje-ji (林園經濟志) and Jeungbo-sallim-gyeongje (增補山林經濟), the plant screen was classified as kinds of support[frame] material, plants and methods of planting. It was found that the supports of Chwibyeong were made of bamboo or the material such as the Jinjangmok (眞長木: a stick of oak) and Giryu (杞柳: Salix purpurea var. japonica). The evergreen coniferous trees including Pinus densiflora, Taxus cuspidata and Thuja orientalis were mainly used for the plant material of Chwibyeong. The general planting method of Chwibyeong was to plant on the ground, but sometimes the container planting was also found on the artificial ground. Second, the term of 'Chwibyeong' in the literatures was used in only the screen made by evergreen trees, and the superordinate category term of it was indicated by 'byeong (屛)'. Therefore Chwibyeong was a compound word formed from 'chwi (翠)' which means the characteristics of evergreen and 'byeong' as tree screen which the support was made by bamboo. And Chwibyeong had semantic context which was combined with the literary symbolization to describe a landscape of green peak and Taoist ideology be inherent from 'twelve peaks of Musan[巫山十二峰]' in Sichuan sheng (四川省). Thirdly, the photograph of Chwibyeong at Juhapru taken by the 1880s, showed that Chwibyeong was made with coniferous trees and was almost 2 meters high. The Chwibyeong at Juhapru was removed during the Japanese colonial era, but a few yew trees(Taxus cuspidata) used for Chwibyeong are still remaining. And some Juniperus chinensis which the composition time is unclear, were cultivated while hung loose its branchs at the sides of Eosumun (魚水門). This Junipers were presumed to be planted by Japanese after Japanese annexation of Korea(1910), and it was judged that both of the roofs of Eosumun's side gates might have been transformed into Japanese style at the same time. Lastly, Chwibyeong at Juhapru was restored in 2008 but it was restored in wrong way from original form without precise research. Especially Chwibyeong was restored with Sasa boreralis which is damaged by frost, so it requires exertion that should revive the originals to plant original material as much as possible. And it needs the development of fabrication technique for Chwibyeong and the application to current landscape architecture.
