  • Background: Acute rhinosinusitis (ARS) is a common condition encountered in ambulatory practice and is one of the most common reasons for antibiotic prescriptions. This study aimed to evaluate the potentially inappropriate antibiotic prescribing for ARS in South Korea and identify influencing factors. Methods: We analyzed Health Insurance Review and Assessment Service-National Patient Samples data. We selected outpatients aged 20 to 64 with ARS, prescribed antibiotics between February and November 2020. Potentially inappropriate antibiotic prescribing was categorized as: 1) inappropriate antibiotic selection and 2) inappropriate antibiotic dosage or duration. Multiple logistic regression was conducted to estimate the impact of various factors on inappropriate antibiotic prescribing. Results: Of 1,210 patients, 80.83% received potentially inappropriate ARS antibiotic prescriptions. Inappropriate antibiotic selection accounted for 43.55%, and inappropriate antibiotic dosage and duration contributed to 37.28%. Otolaryngologists had higher odds ratio (OR) of potentially inappropriate antibiotic prescribing compared to internal medicine practitioners, while dentists had lower OR. Patients aged 20 to 29 years had a higher OR than other age groups, and those who visited primary care clinics had a higher OR than those who visited hospitals. Conclusion: Potentially inappropriate antibiotic prescribing for ARS is prevalent in South Korea. This study identified physician specialty, patient age group, and the level of healthcare facility as factors influencing potentially inappropriate antibiotic prescriptions. Addressing this issue through targeted interventions, such as improved guidelines adherence and patient education, is imperative to mitigate the risks associated with antibiotic misuse and antibiotic resistance.

  • Backgraounds : Recent studies provide the evidences that the efficacy of acupuncture may be no better than placebo or inconclusive. These results are very different from those of the actual clinical situations in many acupuncture medical institutions. Objectives : The present study was designed to evaluate the influencing factors which affect the efficacy of acupuncture scale(FEAS) as the methodological assessment tool of acupuncture for examining acupuncture interventions and to demonstrate the importance of it in randomized controlled trials of acupuncture. Data sources : Electronic data were retrieved from NDSL, Pubmed, sciencedirect, LWW, OVID, Black-Well Synergy, Wiley Interscience, EBSCO HOST, springer, PML, and Kluwer. No electronic data were collected from MEDLIS and MEDLAS. Study selection : The inclusion criteria were five systematic reviews included in Alberta study and all randomized controlled trials obtained from their references. Study analysis : The acupuncture rationale, methods of stimulation, treatment regimen, and the practitioner's background were rated by FEAS, and the scores were compared with those by other methodological assessment tools. Results : The number of positive conclusions of high-rank RCTs by FEAS was the same as or higher than that of high-rank RCTs by other methodological assessment tools. Conclusions : We have analysed 5 systematic reviews and their objectives 58 RCTs using FEAS. Practitioner's background has been described slightly in some reviews and studies. It may directly influence the effectiveness of acupuncture negatively in the systematic reviews.

  • The objective of this study was to characterize factors influencing genetic improvement of dairy cattle for milk production at farm level. Data were accumulated from 305-day milk yields and pedigree information from 1,921 first-lactation dairy cows that calved from 1990 to 2007 on 161 farms in Central Thailand. Variance components were estimated using average information restricted maximum likelihood procedures. Animal breeding values were predicted by an animal model that contained herd-year-season, calving age, and regression additive genetic group as fixed effects, and cow and residual as random effects. Estimated breeding values from cows that calved in a particular month were used to estimate genetic trends for each individual farm. Within-farm genetic trends (b, regression coefficient of farm milk production per month) were used to classify farms into 3 groups: i) farms with negative genetic trend (b<-0.5 kg/mo), ii) farms with no genetic trend (-0.5 kg/$mo{\leq}b{\leq}0.5$ kg/mo), and iii) farms with positive genetic trend (b>0.5 kg/mo). Questionnaires were used to gather information from individual farmers on educational background, herd characteristics, farm management, decision making practices, and opinion on dairy farming. Farmer's responses to the questionnaire were used to test the association between these factors and farm groups using Fisher's exact test. Estimated genetic trend for the complete population was $0.29{\pm}1.02$ kg/year for cows. At farm level, most farms (40%) had positive genetic trend ($0.63{\pm}4.67$ to $230.79{\pm}166.63$ kg/mo) followed by farms with negative genetic trend (35%; $-173.68{\pm}39.63$ to $-0.62{\pm}2.57$ kg/mo) and those with no genetic trend (25%; $-0.52{\pm}3.52$ to $0.55{\pm}2.68$ kg/mo). Except for educational background (p<0.05), all other factors were not significantly associated with farm group.

  • This study focuses on practical appliance of color therapy to skin care. After visiting the notion of color therapy and skin care, this study considers the ideas and background theories for diagnosis of constitution and skin. Cosmic duals force five element theory developed in China was the first introduction; Ayurvedic medicine and seven chakra notion are examined. Cosmic duals force five element theory, an idea describing the composition and movement rule of the cosmic components, adopted five colors(white, yellow, red, blue, and black) for cure purposes. In future, mental effect of the color is examined in the latter part of this study. The practice of the color therapy assigns solarized cream treatment and photo therapy, simultaneously proposes the use of color therapy to the skin care. For the diagnosis of the constitution, cosmic duals force five element theory and ayurvedic medicine are followed in a sequence. Cosmic duals force five element theory introduces five colors. Constitution medicine considers four types, ayurvedic medicine adopts three types, and seven colors are mentioned as chakra colors. Such a variations lead to possible disagreement on constitution analysis and driven colors. This study adopts the above methodologies for selecting potential color therapy for skin care. Adopt of selected cases are purely a part of the proposal. Initially, examined theories serve as a pilot for selecting a representative hypothesis. Followed selection of constitution and matched color for the use of the skin care are the scope of this study. In summary, background methodologies are implemented for the calculation of color therapy.

  • The objectives of this study were to identify QTLs for agronomic traits using introgression lines from a cross between a japonica weedy rice and a Tongil-type rice. A total of 75 introgression lines developed in the Tongil-type rice were characterized. A total of 368 introgressed segments including 285 homozygous and 83 heterozygous loci were detected on 12 chromosomes based on the genotypes of 136 SSR markers. Each of 75 introgression lines contained 0-9 homozygous and 0-8 heterozygous introgressed segments with an average of 5.8 segments per line. A total of 31 quantitative and 2 qualitative loci were identified for 14 agronomic traits and each QTL explained 4.1% to 76.6% of the phenotypic variance. Some QTLs were clustered in a few chromosomal regions. A first cluster was located near RM315 and RM472 on chromosome 1 with QTLs for 1,000 grain weight, culm length, grain width and thickness. Another cluster was detected with four QTLs for 1,000 grain weight, grain length, grain width and grain length/width ratio near the SSR marker RM249 on chromosome 5. Among the 31 QTLs, 9 (28.1%) Hapcheonaengmi3 alleles were beneficial in the Milyang23 background. ILs would be useful to confirm QTLs putatively detected in a primary mapping population for complex traits and serve as a starting point for map-based cloning of the QTLs. Additional backcrosses are being made to purify nearly isogenic lines (NILs) harboring a few favorable Hapcheonaengmi3 alleles in Milyang23 background.

  • Background: Surgical treatment of corrosive esophageal stricture with colon interposition was very widely used. The colon interposition advantage is low reflux esophagitis risk and preservation of gastric capacity and peristalsis. This procedure was introduced by Orsoni and much improved. But, if stomach injury was minimal, gastric interposition is useful due to simple technique and low complication. Material and Method: Esophageal reconstruction by the transhiatal esophagectomy and intracervical esophagogastrostomy was done in 7 patients of corrosive esophageal stricture at Dong-San medical center from January 1998 to December 2007. Result: There were six female and one male patients raBackground Surgical treatment of corrosive esophageal stricture with colon interposition was very widely used.

  • Sustainable fashion products have different characteristics from typical fashion products. Therefore, this study focuses on shoes while exploring the expansion and development of sustainable fashion consumption as well as consumers' perceptions of the sustainability approaches practiced by shoe companies. In-depth interviews were conducted with 24 consumers, who had purchased sustainable shoes, in order to understand their purchase decision-making process and consumption characteristics, using the seven stages of the EBM model. In the "need recognition" stage, the survey participants' social background and family influences were categorized as macro factors, while their personal background influences were categorized as micro factors. In the "evaluation of alternatives" stage, participants reconfirmed whether or not to make a purchase based on the product's properties, such as price, brand value, and offered services. In the "purchase" stage, participants' purchase channels were determined according to their preferences as well as the selection pattern they followed until the final purchase within the chosen channel. In the "consumption" stage, the start of product ownership coincides with the start of using the products after making a purchase. In the "post-purchase assessment" stage, higher positive experiences led to a higher repurchase intention of sustainable shoes, while negative experiences caused participants to defer consumption and made them experience a sense of guilt for failing to consume sustainably. During the "post-purchase behavior" stage, which focused on the categories that the customers prioritized, many participants spread information about sustainable fashion to specific individuals through active online WOM behavior.

  • 최근 초고속 통신망 및 멀티미디어 관련기술의 발달로 인해 멀티미디어 데이타를 좀 더 효율적으로 전송하고 저장, 검색하는 기술이 요구되고 있다. 그 중에서 의미 기반 영상 검색은 색상, 질감, 모양 정보 등의 저 차원 특징 정보와 이미지 데이타에 의미를 부여하기 위해 주석 처리하는 것이 일반적이다. 그리고 부여된 키워드와 같은 어휘 사전을 이용하여 의미기반 정보검색을 수행하고 있지만, 기존의 키 워드기반 텍스트 정보검색의 한계를 벗어나지 못하는 문제를 야기 시킨다. 두 번째 문제점으로 내용 기반이미지 검색시스템에서 검색 성능이 떨어지며, 복잡한 배경을 가진 이미지에서 객체를 분리하기가 어렵고, 그리고 영역의 과잉 분할로 인하여 영역 추출이 어렵다. 그리고 복잡한 다중 객체를 가진 이미지에서 객체들을 분리하기 어렵다는 것이다. 이러한 문제점들을 해결하기 위해서, 본 논문에서는 총 다섯 가지 단계로 처리할 수 있는 내용 기반 검색 시스템을 구축한다. 다섯 단계 중에서 가장 중요한 부분은 RGB 이미지들 중에서 배경이 가장 큰 것과 가장 작은 것을 추출한다. 특히, 배경이 가장 큰 이미지를 이용하여 피사체와 배경을 추출하는 방법을 제안한다. 두 번째 문제점을 해결하기 위해서, RGB 채널 분할 기법을 이용하여 객체를 분리하고, Watermerge의 임계값을 이용하여 영역의 과잉분할을 최적화하며, RGB 채널 선택 기법을 이용하여 다중객체를 분리하는 방법을 제안한다. 실험을 통하여 기존에 검색하기 어려웠던 복잡한 객체들을 검색하는 방법들을 대체할 수 있도록, 제안한 기법이 기존의 방법보다 검색 성능이 우수함을 입증한다.과 황산이온의 농도에 따르는 것으로 생각된다. 이상과 같이, 에트린자이트는 콘크리트 내에서 다양한 내외부적인 화학작용 따라 특징적인 산출 양상을 보이며, 주변 환경 조건에 따라 다른 광물로 전이되는 나타내었다. 이러한 연구결과, 에트린자이트의 생성에 따른 콘크리트의 성능저하는 그 광물학적 특성과 분포양상에 관련성을 가지는 것으로 나타났다.인 상관관계를 보이지 않는 것으로 나타난다. 이에 비해서 팽윤도는 벤토나이트의 광물조성, 표면전하 특성, 입도 및 형상 등의 물리화학적 성향을 포괄하는 체표면적 수치와 대략적으로 반비례적인 관계를 보인다 따라서 벤토나이트 현탁액에서의 유변학적 특성은 몬모릴로나이트의 표면전하 특성, 형태, 입도 및 조직 등의 차이에 의해서 달라지는 점토 입자들의 응집특성 및 취합결정체의 형상에 주로 규제되고, 제올라이트와 같은 미세한 불순 광물성분들의 영향도 부수적으로 관여되는 복합적인 성향인 것으로 해석된다.18.88%이상 향상시키는 것으로 나타났다. 3. 유지방 함량 23.80%인 control 치즈의 cholesterol 함량은 81.47mg/100g이었고, 균질압력 1200psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 2%를 첨가한 cheese에서는 cholesterol 함량이 20.15mg/100g으로 cholesterol 제거율이 75.27%로 가장 높게 나타났다. 4.

  • 이 연구는 자유탐구의 주제 선정과정에서 중학생들이 겪는 어려움의 유형을 파악하기 위해 실시되었다. 연구목적의 달성을 위해 중학교 1학년 학생 11명이 참여하였고, 자유탐구 활동지와 심층면담의 분석을 통해 귀납적 분석을 실시하였다. 학생들은 자유탐구를 경험하면서 주제선정단계에서 한번 이상의 어려움을 경험하였고, 어려움의 경중은 개인차가 있었지만 주제 선정과정의 체계화된 안내가 필요함을 확인하였다. 자유탐구활동의 주제선정단계 중 탐구대상선정의 어려움으로는 제한 없는 탐구대상 선정에 대한 부담감, 과학적 탐구대상의 이해 부족, 학생들의 과학적 탐구 호기심 부족이 나타났다. 탐구대상을 제한하는 것에 대해서는 학생 선택이 필요하다. 대상선택의 기회제공 유무를 판단하여 자유탐구의 본 취지가 수용된 전략적 지도가 필요하다. 자유탐구활동의 주제선정단계에서는 과학적이지 못한 주제 선정, 단답형식의 해결 가능한 주제 선정, 탐구의 실현 가능성 여부, 주제에 관한 선언적 지식의 부족, 재미에만 집중된 주제를 선택하여 어려움을 겪는 것으로 나타났다. 참가학생들은 자유탐구활동에 대한 경험 부족, 주제선정단계별 실패로 인한 흥미 저하, 자유탐구활동 자체에 대한 부담감을 이유로 자유탐구활동을 중단하는 것으로 나타났다. 자유탐구활동의 성공적 실행을 위해 주제선정단계에 대한 구조화된 안내가 이루어져야 한다.
