4차 산업 혁명 시대의 도래에 따라 쇼핑의 행태는 더욱 빠르게 오프라인에서 온라인으로 이동하고 있다. 온라인 쇼핑에서 고객의 정보요구를 가장 집약적으로 보여주는 것이 바로 검색 질의이다. 하지만 검색 분야에서도 검색 질의 관련 연구 사례는 많지 않으며 대부분의 검색 질의 연구 분야 선행 연구들은 연구자의 정성적인 판단에 근거하여 제한적인 주제와 데이터 기반으로 연구되어 왔다. 이에 본 연구는 검색 질의 연구 분야에 기계학습을 적용하여 검색 질의와 검색 이후 이용자가 조회한 문서명 로그를 기반으로 토픽모델링 수행 후 검색 질의 주제를 정의함으로써 데이터 기반의 정량적 방법론으로 15개의 검색 질의 주제 유형을 정의하였다. 또한 기존 검색어 자체만을 보고 판단하던 주제 유형에서 나아가 검색 행동특성을 반영한 유형을 정의하기 위하여 주성분 분석을 통해 주요 변수를 추출 후 각 주제별 검색 행동특성을 분석함으로써 검색 탐색 활성도, 상품 관여도에 따른 4가지의 새로운 검색 질의 유형 분류체계를 제시하였다. 본 연구결과는 효과적인 검색서비스 구축 및 검색 시스템 개발에 기여할 것으로 기대된다.

본 연구에서는 현직 법관 24명을 대상으로 법관들이 재판과 관련하여 사회여론을 어떻게 개념화하는지와 사회여론에 대해 어떤 태도를 취하는지에 대한 초점 집단 면접(FGI)을 실시하고, 인터뷰 내용에 대한 근거이론적 분석과 구조적 토픽 모델링(STM)을 수행하였다. 근거이론적 분석 결과에 따르면, 연구 참여자들은 사회상규, 사회통념, 법감정, 국민정서를 여론과 개념적으로 구분하였고, 여론을 특정한 법적 쟁점이나 사건에 대한 일시적이고 감정적인 반응과 정책에 대한 지속적인 의견으로 구분하여 이해하였다. 그리고 사건의 종류나 법적 쟁점에 따라 여론이나 사회통념에 대해 다른 태도를 취하는 것으로 나타났다. 토픽 모델링 결과는 근거이론적 분석 결과와 상당한 유사성을 보였고, 특정 토픽의 발현 가능성은 연구 참여자들의 담당 사건 종류에 따라 통계적으로 유의미한 차이를 보였다.

-Nun is generally known as a Topic marker in Korean. However, when it is combined with an accent, it is thought to have a different function, which is alleged to indicate 'contrast' (Kuno 1972). Although the fact that -nun marked item generates some kind of 'contrastive meaning' is uncontroversial, what 'contrast(ive)' means is still unclear. In t his paper, I propose that accented -nun generates two types of implicit propositions in addition to its at-issue meaning. A simple sentence has been repeatedly tested in various models in order to see what type of proposition each proposition corresponds to and it has been concluded that one is presupposition and the other is implicature. This tedious-looking test forms the main part of the first-half of this paper. The presupposition is the essential factor for the -nun marked item to obtain the 'contrastive' meaning. Based on the generation of this presupposition, I argue that -nun works as a contrast operator in a sentence. To illustrate -nun's function as a contrast operator forms the latter part of this paper.

Purpose: Chronic hepatic disease is caused by inappropriate management of the hepatitis B virus. In Korea. there is an increasing number of chronic hepatic patients. who are at risk of dying from liver failure or hepatocellular carcinoma. Therefore it is important to manage the hepatitis B virus appropriately. Method: The patients diagnosed with chronic hepatic disease or HBV carrier who registered at a community health center or hospital were assessed regarding health man agement status and educational needs. The data was collected from 179 persons by convenient sampling between May, 2000 and April. 2001. The data were was analyzed for general characteristics using the descriptive method, factors influencing educational needs and health management using t-test and ANOVA. Results: 1. The average health management score was 18.2 from 12 to 24 range. Those who unknown were unaware of the presence of HBsAg, attending the educational program and keeping undergoing treatment at the community health center or hospital were had a higher management score(p< .05). 2. The educational needs regarding nutritional management(64.8%) was the highest topic with chronic hepatitis patients. The second highest topic was spreading prevention among family members (52.0%), and keeping medication (45.8%), the degree of physical activities(44.1%), and spreading prevention in public(39.1%). Those who were unaware of the presence of HBsAg (p< .001), less than 12 months after HBsAg (+)(p< .05), keeping treatment (p< .05) were higher educational needs. 3. The use of alternative therapy was 27.9% of subjects. The subjects thought it was helpful for disease management(42.1%), mostly, family members and relatives recommended to use (57.9%), and medical regimen was ignored during the alternative therapy. Conclusion: Based on the results, an educational program about prevention of type B hepatitis and management for patients having type B hepatitis should be developed.

This study is a research about the effect on achievement, retention and attitude of learning descriptive statistics with the computer software. For this study, 60 students are randomly divided two groups, one is an experimental group using software, the other one is a control group using lecture type of learning statistics. For the analysis, both groups are divided three subgroups according to mathematical ability. Also the topic "descriptive statistics" is divided by 5 subtopics. The test is divided three parts(computation, concept and application) according to knowledge type. The attitude toward statistics is investgated with questionaire and interview with both groups. The achievement test is taken after 8 class periods. The retention test were administered together six weeks after achievement test. The experimental group achieved significantly better than in concept type while the control group performed significantly better than the experimental group in computation type. With respect to the attitude toward statistics, lower ability students may have been negatively affected by the use of software.

Purpose : This study sought to investigate research trends regarding joint mobilization type among patients with shoulder joint diseases. Methods : A scoping review was conducted according to the five steps outlined by Arskey and O'Malley and PRISMA-ScR. We searched six domestic databases (ScienceOn, DBpia, Riss, Kmbase, Kiss, KCI) and three international databases (CINAHL, Pubmed, Cochrane central) between 2013 and June 2023. The keyword terms used were 'joint mobilization', 'Kaltenborn', 'Maitland', 'Mulligan', and 'shoulder joint'. Results : There were a total of 44 studies that investigated the topic, and these were divided into quantitative analysis and topic analysis. In terms of publication year, the number of studies within the last five years has increased more than compared to the previous five years, with most of them being randomized clinical trials. In shoulder joint diseases, it was found that the majority of joint movement studies focused on adhesive joint cystitis and shoulder collision syndrome. The Mulligan concept was the most commonly studied type of joint motion. The dependent variables used included pain, joint function (disability), and muscle function. The visual analog scale was the most commonly used for the pain variable, followed by the numeric rating scale. For joint function and disability variables, range of motion was the most commonly used, followed by shoulder pain and disability index, and disabilities of the arm, shoulder, and hand. For muscle function, variables such as muscle tone, strength, and activity were used. Conclusion : We believe that findings of this scoping review can serve as valuable mapping data for joint mobilization research on shoulder joint diseases. Further studies including systematic reviews and meta-analyses based on these results are recommended.

We investigate the existence of homoclinic orbits of the following systems of $Li{\'{e}}nard$ type: $a(x)x^'=h(y)-F(x)$, $y^'$=-a(x)g(x), where $h(y)=m{\mid}y{\mid}^{p-2}y$ with m > 0 and p > 1 and a, F, 9 are continuous functions such that a(x) > 0 for all $x{\in}{\mathbb{R}}$ and F(0)=g(0)=0 and xg(x) > 0 for $x{\neq}0$. By a series of time and coordinates transformations of the above system, we obtain sufficient conditions for the positive orbits of the above system starting at the points on the curve h(y) = F(x) with x > 0 to approach the origin through only the first quadrant. The method of this paper is new and the results of this paper cover some early results on this topic.
