"Hwasan 102" is a new cold-tolerant Italian ryegrass(Lo1ium rnultiflorum L.) variety developed by theNational Livestock Research Institute(NLRI) in 1999. Having cold tolerance in Italian ryegrass is an importantfor enlargement of cultivation area and increase of productivity in Korea. To develop the cold-tolerant varietyof Italian ryegrass, cold-tolerant clones survived under - 13- - 14$^{\circ}$C of minimum average air temperature(MAAT) in January were selected at Dun Nae, Kwangwon Province in 1993. Five of selected clones werepolycrossed for seed production by NLRI, RDA, in 1995."Hwasan 102" was tetraploid variety, dark green in leaf color and broad in flag leaf width. Also it hassemi-prostrate and medium growth habit in late autumn and in early spring, respectively. "Hwasan 102" withlow plant height at harvesting time was excellent in lodging tolerance. First heading date of "Hwasan 102"was 19th May, it was similar to that of Marshall. Expecially, "Hwasan 102" survived about 60% under - 10- - 12$^{\circ}$C of MAAT in January, so it could be cold-tolerant variety that can be safely cultivated in regionshigher than -9'C of MAAT in January. Compared with Marshall, "Hwasan 102" showed 8% higher freshyield (59.2MT per ha) but it showed 2% lower dry matter yield (9.6MT per ha). Higher IVDMD and TDNand lower ADF and NDF were observed in "Hwasan 102" than those of Florida 80 and Marshall in Foragequality.(Key words : Italian ryegrass, Cold tolerance, New variety "Hwasan 102")rshall in Foragequality.(Key words : Italian ryegrass, Cold tolerance, New variety "Hwasan 102")san 102&")ot;)

This study suggests a sentence generating method to help those who have language impediment with their communication. The method suggested in this study was constructed into a system in order to be applied to AAC system. AAC system is a personal portable device that generates sentences. Those who have language impediment need another communication method, causes inconvenience when used in a conversation with those who don't have the same trouble. The method of inputting both consonants and vowels can be inconvenient and time consuming for a conversational communication because of the number of the key strokes. The lexical information for the sentence generating of this study defines the user's domain, collects the adequate words and sentences, and extracts and classifies the characteristics of the collected words. The comparison between the number of key strokes for sentence generating using the system and that of inputting consonants and vowels using a keyboard was made in order to evaluate the usefulness the sentence generating method.

The purpose of this study was to examine the uniform image of Korean herbal cosmetic brands amongst Korean and Chinese consumers. This study would enable us to explore a BI strategy to enhance international competitiveness of Korean herbal cosmetics brands. The results were as follows. The key words of BI pursued by Sulwhasoo were dignified, novel, graceful, soft, gaily, natural, Korean, modern, and international. Korean people felt that the uniform was graceful and soft, which accorded with Sulwhasoo BI, but also it was trite and dingy, indicating a negative and opposing image. On the other hand, Chinese people felt that the uniform was dignified, novel, graceful, natural, modern, and international, indicating that it matched with Sulwhasoo BI. In The History of Whoo, the key words of BI pursued by the brand were precious, soft, gorgeous, gaily, and natural. The Koreans felt that the uniform was intelligent, and decent, but conversely, it was also austere and dingy, indicating a negative image. The Chinese felt that the uniform was common, hard, austere, dingy, and unnatural, indicating an opposing image to BI. Finally, a uniform design was developed to improve on its problems, establish The History of Whoo's brand identity, and its brand image. First of all, 'The Quintessence : noble passion' was set up as a developmental concept. The textiles, clothing, and accessories were designed using the symbolic elements from The History of Whoo as a motif. Uniforms were developed for spring, fall, and summer.

This study was conducted to compare solo eating perceptions and dietary behaviors in the Seoul and Gyonggi-do regions according to gender. The study focused on the dietary perceptions, solo eating, eating together, dietary habits, food intake patterns and 38 keywords pertaining to solo eating. Of 411 subjects, 207 (50.4%) were males and 204 (49.6%) were females. The biggest problem that respondents perceived in their dietary life was irregular eating. Women prepared meals more often than men (p<0.001) and ate more instant and frozen food than men (p<0.05). Both males and females missed breakfast most, and the amount of the population eating breakfast alone ranked second highest. Women had lunch alone more often than men, while men ate dinner alone more often than women (p<0.01). All respondents spent 5~15 min when eating alone. Women avoided excessive smoking and drinking more than men (p<0.001). Men related key words regarding solo eating with negative emotions such as 'lonely', 'boring', and 'feel sorry when I see someone eating alone in a restaurant' more than women. Conversely, women related more positive key words with eating alone such as 'free', 'joy', and 'my own time'. Dietary lives of Koreans have rapidly changed along with social changes. Our research findings will contribute to increased comprehensive menu development and HMR development in the foodservice industry.

Objectives To determine the evidence of effectiveness and safety of extracorporeal shock wave therapy (ESWT) with meridian and acupoint theory for knee osteoarthritis. Methods By March 3, 2021, five foreign electronic databases and six Korean medical electronic databases were reviewed with the key words 'extracorporeal shock wave' and '(acupoint OR acupuncture point)'. This key words was set up to increase the sensitivity of the search. After the search, knee osteoarthritis study was selected based on the title and abstract and then included after full-texts were read. Results Five randomized controlled trials were eligible in our inclusion criteria. The meta-analysis of three studies showed positive results for the using ESWT with meridian and acupoint theory for knee osteoarthritis compared with the control group on efficancy rate, visual analog scale and lysholm knee score. but there remains a conundrum regarding the safety of ESWT in the treatment of knee osteoarthritis. Conclusions Most of studies showed ESWT with meridian and acupoint theory were statistically effective to knee osteoarthritis. However there are limitations that the number of selected studies was small, risk of bias was unclear. So use of ESWT with meridian and acupoint theory for knee arthritis has limited evidence compared to usual care.

Objectives This review was conducted to evaluate effectiveness and safety of extracorporeal shock wave therapy (ESWT) with meridian and acupoint theory for adhesive capsulitis. Methods By December 2021, 11 electronic databases were reviewed with the key words 'extracorporeal shock wave' and '(acupuncture OR acupoint OR meridian)'. This key words was set up to increase the sensitivity of the search. After the search, adhesive capsulitis study was selected based on the title and abstract and then included after full-texts were read. Results Five randomized controlled trials were eligible in our inclusion criteria. The meta-analysis of 3 studies showed positive results for the using ESWT with meridian and acupoint theory for adhesive capsulitis compared with the control group on efficancy rate and range of shoulder flexion. Conclusions Some studies showed ESWT with meridian and acupoint theory were statistically effective to adhesive capsulitis. But the evidence is limited due to the defective design of the included randomized controlled trials (RCTs). So use of ESWT with meridian and acupoint theory for adhesive capsulitis has limited evidence. More well-designed RCTs are required to provide clearer evidence for this claim.

In this study we examined the topic analysis and correlation analysis by text mining to extract meaningful information or rules from the self introduction letter of freshman at Korea National College of Agriculture and Fisheries in 2020. The analysis items are described in items related to 'academic' and 'in-school activities' during high school. In the text mining results, the keywords of 'academic' items were 'study', 'thought', 'effort', 'problem', 'friend', and the key words of 'in-school activities' were 'activity', 'thought', 'friend', 'club', 'school' in order. As a result of the correlation analysis, the key words of 'thinking', 'studying', 'effort', and 'time' played a central role in the 'academic' item. And the key words of 'in-school activities' were 'thought', 'activity', 'school', 'time', and 'friend'. The results of frequency analysis and association analysis were visualized with word cloud and correlation graphs to make it easier to understand all the results. In the next study, TF-IDF(Term Frequency-Inverse Document Frequency) analysis using 'frequency of keywords' and 'reverse of document frequency' will be performed as a method of extracting key words from a large amount of documents.

Standards-curriculum based archival contents for education is the best effective teaching and learning units for historical thinking abilities. This paper purposes a developing procedures of an archival contents for education that is theoretical instructions of developing an archival contents for education by the National Archives of Korea. This paper can be used of the theoretical bases for the National Archives of Korea by proposing the methodology of development of an archival contents for education. The developing procedures of an archival contents for education is the same with the procedures of developing an e-learning contents that has planning, analyzing, designing, developing and assessing steps but it is characterized by an archival contents for education that is curriculum standards analysis, collection analysis, and detailed design for structured formats in effective-accomplishments for teaching-learning objectives. I propose the procedures for determining teaching-learning subjects that enable the development of an archival contents for education by curriculum standards analysis. I also propose the procedures for deriving the key words from the teaching-learning subjects. Collection analysis methods analyze key records that correspond to the learning subjects according to the selection criteria of primary sources. In the steps of designing, titles of contents and contents structures have to be determined and storyboards based on flowchart of learning have to be made of according to the results of analyses. In the steps of developing contents, making a copy of primary sources like a original is the key points. And also in the steps of assessment, products of teaching-learning contents to effectively achieve the teaching-learning objectives have to be estimated by the appraisal board. Finally I propose that user's survey research after the services have to be reflected on contents updates and new developments of contents.
