To investigate a simple and rapid screening method for photosynthetic inhibitory herbicides, responses of tobacco(Nicotiana tabacum L.) and liverwort(Marchantia polymorpha L.) PA(photoautotrophic) cells to various commercial herbicides with different modes of action and leaf extracts of four weed species were compared. PET (photosynthetic electron transport) inhibitory type of herbicides has greater inhibitory effect in liverwort photoautotrophic cells than the photomixotrophic and heterotrophic cultured cells. Similary, PET inhibitory type of herbicides inhibited the oxygen evolution more in liverwort PA cells than the other type of herbicides. Based on oxygen evolution, 60% inhibition was observed by the 10% aqueous extracts of Polygonum hydropiper, while there was 100% inhibition by the 10% methanol extracts of Polygonum hydropiper. This assay gave well correlated results to the Hill reaction data using isolated thylakoids. Thus liverwort photoautotrophic cells might be suitable materials for rapid screening method for photosynthetic inhibitory herbicides.

Objective: The purpose of this study is to analyze comprehensive lifestyle assessment and other assessments which evaluate essential lifestyle factors, including physical activity, nutrition and activity participation. Methods: To analyze the comprehensive lifestyle assessment, from January 2001 to June 2019, a literature search was conducted using the CINANL, NDSL, PubMed, and RISS databases. The search terms were 'lifestyle assessment' OR 'lifestyle profile' OR 'lifestyle test'. In terms of other assessments of essential factors of lifestyle, from January 2010 to June 2019, articles were searched using similar databases. The search terms were 'physical activity assessment' OR 'physical activity participation profile', 'nutrition assessment', 'activity participation assessment' OR 'activity participation and lifestyle'. Results: A total of 4,165 articles were obtained, and finally 31 articles were selected according to the inclusion criteria. Among 31 articles, there were five with comprehensive lifestyle assessments, and all of them were self-report questionnaires. The most popular assessments were the Health Enhancement Lifestyle Profile (HELP) and the Health-Promoting Lifestyle Profile (HPLP), which were used in three articles (33%). In terms of assessment of physical activity, the most frequently used evaluation method was the self-report questionnaire, which was used in seven articles (58%) followed by objective assessments, which were used in four articles (33%). It was demonstrated that the Mini-Nutritional Assessment (MNA) was the most frequently used for nutrition assessment in the elderly. There were five types of assessment tool used for activity participation. Among them, meaningful activity participation assessment (MAPA) was the most frequently used tool. Conclusion: As a result of the systematic review, it was found that there are 21 assessments related to the evaluation of lifestyle in the elderly. Most assessments employed the self-report questionnaire method and mainly evaluated frequency and duration of participation in drinking, smoking, exercise, nutrition and social activities. Assessments of essential lifestyle factors were the self-report questionnaire method and the participation and frequency of activity. Therefore, by analyzing assessment tools, types of items and measurement methods of comprehensive lifestyle assessments and other assessment of essential lifestyle factors, this study provides the basic data on which to develop a standardized assessment tool that can evaluate the multifaceted lifestyle profile of the elderly.

This study conducted a meta-analysis of the effects of self-management intervention for reducing the depression and anxiety of osteoarthritis patients. The research sources were PubMed, EMBASE, CINAHL, Ovid-MEDLINE and Korean databases from the Korean and foreign literature published until September 30, 2019. The R version 3.5.1 program was used to identify the effectiveness of self-management intervention. As a result, 11 studies from a total of 1,877 articles in the relevant literature were analyzed, and the total number of participants was 2,751. The results showed that the overall effect size for reducing depression and anxiety was -0.44 (95% CI: -0.66, -0.22) in osteoarthritis patients (p <.001). On the sub-analysis, depression was -0.37 (95% CI: -0.66, -0.08), and anxiety was -0.56 (95% CI: -0.92, -0.20). To explain the heterogeneity, the meta-ANOVA was the setting, duration, and provider of intervention. Analysis of the publication bias was performed by a Funnel plot, which was visually relatively symmetrical and was not asymmetric according to Egger's Regression test (bias=0.19, p=.928). The results of this study established clinical evidence by identifying the effects of self-management intervention for reducing the depression and anxiety of osteoarthritis patients.

Advancing of mobile device is remarkable, so the research on mobile input device is getting more important issue. There are lots of input devices such as keypad, QWERTY keypad, touch and speech recognizer, but they are not as convenient as typical keyboard-based desktop input devices so input strings usually contain many typing errors. These input errors are not trouble with communication among person, but it has very critical problem with searching in database, such as dictionary and address book, we can not obtain correct results. Especially, Hangeul has more than 10,000 different characters because one Hangeul character is made by combination of consonants and vowels, frequency of error is higher than English. Generally, suffix tree is the most widely used data structure to deal with errors of query, but it is not enough for variety errors. In this paper, we propose fast approximate Korean word searching system, which allows variety typing errors. This system includes several algorithms for applying general approximate string searching to Hangeul. And we present profanity filters by using proposed system. This system filters over than 90% of coined profanities.

The taste characteristics and functionality of low-utilized small longfinned squid as affected by two stage enzyme hydrolysis were examined. In taste active-components, total free amino acid contents in hot-water and autolytic extract, two stage enzyme hydrolysate (TSEH) of longfinned squid were 2,792.5 mg%, 8,393.8 mg% and 9,186.1 mg%, respectively. The major free amino acids were Pro, Leu, Glu, Tau, Lys, Arg, Phe, Val and Ile. As for quarternary ammonium bases, betaine was the principal component (593.8 mg%) and also contents of TMAO, AMP in longfinned squid TSEH were 234.8% mg% and 51.0 mg%, respectively. The major inorganic ions in TSEH were Na(874.0 mg%), K (398.2 mg%), Cl (1,213.1 mg%) and PO$_4$(995.9 mg%). From the results in sensory tests, TSEH was superior to other extracts on the aspects of taste characteristics such as umami intensity, sweetness, taste harmony and transparency of extract. Also TSEH of longfinned squid revealed very higher Angiotensin-I converting enzyme inhibition ratio (92.1%) than those of hot-water and autolytic extract.

유효가뭄지수(Effective Drought Index, EDI)는 현재 기후에 대한 과거, 미래 기후에서의 상대적인 가뭄 특성 변화를 평가하기 위해 최근 30년간의 일 강수량 자료를 고정된 기준치로 사용한다. 이에 따라 장기간에 걸친 다양한 기후변화에 대한 인간 사회의 적응을 고려하며 가뭄의 영향을 평가할 때에는 한계점이 있다. 이 연구에서는 EDI의 기능을 확장하기 위해 자가교정 유효가뭄지수(self-calibrating EDI, scEDI)를 제안하고 그 성능을 평가하였다. 기존 EDI와는 다르게 scEDI는 관측시점을 기준으로 30년씩 이동하며 시간에 따라 변화하는 기후값을 기준치로 사용한다. 우리나라 서울관측소에서 1777년부터 2020년까지 누적된 244년간의 일 강수량 자료를 바탕으로, scEDI와 3개의 서로 다른 기후 기준치를 가진 기존 EDI를 계산하여 평가된 가뭄들의 특성을 비교하였다. 그 결과, 기후 기준치에 따라 서로 다른 가뭄 특성들을 보인 기존 EDI와 달리, scEDI는 변화하는 기후를 고려하여 분석기간에 걸쳐 가뭄의 특성을 일관되게 평가할 수 있는 것으로 밝혀졌다. 1807년부터 1907년까지 가뭄과 관련된 조선왕조실록의 기록과 scEDI가 평가한 과거 가뭄 사례들과 비교해 본 결과, scEDI가 탐지한 가뭄 사례들과 실제 조선왕조실록의 가뭄 기록이 비교적 잘 일치하여, scEDI가 과거의 사회적 가뭄을 잘 탐지하는 것으로 나타났다. 또한, 최근의 사회적 가뭄에 대한 scEDI의 탐지 능력을 평가하기 위해 구글과 네이버에서 2016년부터 2018년까지 수집된 가뭄 관련 검색어 소셜 빅데이터를 사용하여서 비교하였다. 그 결과, 과거와 마찬가지로 현재에서도 scEDI가 평가한 가뭄의 변화와 소셜 빅데이터에서 나타난 가뭄에 대한 사회적 반응이 잘 일치하는 것으로 나타났다.

This study presents a systematic literature review aimed at integrating and analyzing the research findings regarding the components of various self-care intervention programs conducted for individuals with chronic obstructive pulmonary disease (COPD) both domestically and internationally. The paper selection criteria were established based on materials from PubMed, CINAHL, EMBASE, /MEDLINE, RISS, DBpia, KISS, and KMbase databases, covering the period from January 1, 2000, to September 30, 2022. The inclusion criteria included controlled pre-post experimental study designs. A total of 23 studies were included in this systematic review. The intervention-related factors examined included the sample size, type of intervention mediator, intervention frequency, and duration. Additionally, factors associated with intervention effects, such as measurement tools and variables, were analyzed. The findings of the analysis support the notion that self-care intervention programs for COPD can contribute to the prevention of symptom exacerbation and hospital readmissions among patients. Consequently, the development of a tailored self-care intervention program specifically designed for COPD patients in South Korea is warranted, considering aspects such as patient accessibility, convenience, and motivation for long-term sustainability.

The typical Kinetic Family Drawing (KFD) Web database system, a form of prototype system, has been developed, relying on the suggestions from family art therapists, with an aim to handle large amounts of assessment data and to facilitate effective implement of assessment activities. However, unfortunately such a system has an intrinsic problem that it fails to collect clients' behaviors, attitudes, facial expressions, voices, and other critical information observed while they are drawing. Accordingly we propose the ontology based video event analysis and video retrieval system in this paper, in order to enhance the function of a KFD Web database system by using a web camera and drawing tool. More specifically, a newly proposed system is designed to deliver two kinds of services: the client video retrieval service and the sketch video retrieval service, accompanied by a summary report of occurred events and dynamic behaviors relative to each family member object, respectively. The proposed system can support the reinforced KFD assessments by providing quantitative and subjective information on clients' working attitudes and behaviors, and KFD preparation processes.
