  • The purpose of this study is to determine paternal rearing behavior according to rearing characteristics and demographic characteristics. This study is designed as descriptive survey. This study's subjects are 200 people who live in Daegu, Gyeongbuk, Seoul and Gyeonggido and they have preschool children of 3-6years old. They live with their children together and they are bringing up their children with a spouse, and they agreed with this study. It was measured by the instrument that 3 nursing scholars modified for content validity based on 18 items which developed parental behavior questionnaire of Bigner(l977). The data were analyzed by the SPSS/PC program with descriptive statistics, t-test and ANOVA test. It was used Scheffe' test as post-hoc measurement. As a result of analysis is the following. 1. The results that are measured paternal rearing behavior by mean and standard deviation are that 'activity of play interaction' score was the highest($280{\pm}.59$), and then 'activity of daily living'($2.41{\pm}.58$), and then 'activity of discipline'($2.40{\pm}.93$). The lowest area was 'activity of outhouse'($225{\pm}.85$). As examined paternal rearing behaviors by item, 'express physical affection to children' was the highest and the next items is 'consult with wife about children's rearing problem.'. Item that was shown the lowest score was 'wash children's dress'. 2. Compared paternal rearing behaviors level by demographic characteristics, that showed Significant differences among the fathers job type(F=3.492, p=.005), family monthly income (p=2.011, p=.047), children's number(F=4.641, p=.011). 3. Compared paternal rearing behaviors level by rearing characteristics, that showed significant difference in the satisfaction of marred life (F=3.932, p=.021). In spite of Paternal rearing behavior can influence on children's health and health activity, that is apt to exclude in various family health educational program development and application in nursing field. Therefore, nursing researches about paternal rearing behavior will have to be needed to study in the future.

  • The objective of this study was to investigate visual elements of steampunk fashion and provide base line data for innovative fashion design ideas and products. We investigated design characteristics of steampunk fashion style shown in 3 movies and 3 animations. Based on the investigation, the research drew intrinsic value of steampunk fashion from three brands 'Vivienne Westwood', 'Dolce & Gabbana' and 'Alexander McQueen'. As the research analyzed movies and animations revealing steampunk style, various characteristics were found and assorted into similar categories. Subcategories of steampunk fashion are pluralism, rebellion and heterogeneity. The followings are result of analyzing three designer collection listed above. First, steampunk fashion made by designers used various color and materials to express multi-pluralistic(multiplicity) characteristic. Second, fashion style in collections revealed artistic and experimental design. This adventurous and innovative characteristic is categorized as rebellion feature. Third, steampunk fashion style used mix-match of unexpected materials or unbalanced silhouette to create a complete fashion style by combining styles in duplicity which could've lack harmony. Intrinsic value of steampunk is defined as graffiti of 19th century's science technology and utopia spirit. Longing for past and fantasy was expressed into fashion. Steampunk fashion wants to escape reality and tries to recreate history of the past faded away with technological development. It defines steampunk as freedom, deviation and fantastical utopia in positive point of view. Furthermore, aesthetic implication of steampunk style found in this research can make a boundary of steampunk style clear and become reference for future researches regarding steampunk fashion.

  • This study was motivated by the need to identify the characteristics of professionals involved in planning exterior spaces in urban development projects and to provide guidelines for maintaining the identity of urban images. Urban development's impact on external spaces can alter the image of the urban structure, especially due to the many boundaries between urban and rural areas. Therefore, there is a need for public standards for external spaces in such projects. This study collects and analyzes experts' opinions to understand the characteristics of each professional, selects the relative importance of each, and uses this as a guideline for step-by-step deliberation in planning external spaces. The research scope includes analyzing each expert's characteristics based on the external space evaluation items from Lee Limjeong's 2023 study, which builds upon existing research, and presenting the importance and priority of each expert. As a methodology, a questionnaire was conducted for each expert group using the indicators established in Lee Lim Jung's 2023 study for external spaces in urban development projects. An in-depth analysis was performed using the Analytic Hierarchy Process (AHP) for each expert. Using AHP analysis, the composite weight for each of the 17 detailed items was first adjusted by the number of item weights to account for the classification level of the large and detailed items. Then, the composite importance was calculated by multiplying the importance of the large, medium, and detailed classifications. The calculated composite importance was finally adjusted by applying the number of item weights again, ensuring the sum of the 17 importance values equals 1. The final importance calculated through this process was then presented by occupation.

  • 2007년 10월 11일, 한강일대를 오가는 관광 및 출퇴근 용도의 수상택시가 운항을 시작하였다. 그러나 서울의 교통난을 해결할 수 있을 것이라는 기대와는 달리 경제성, 접근성과 관련된 문제로 인해 이용이 활성화 되지 못하고 있는 실정이다. 따라서 본 연구에서는 대중교통관련 선행연구고찰을 토대로 수상택시 서비스 평가 항목을 개발한 후, 이용자 만족도 설문조사, 중요도-만족도 분석(IPA: Importance Performance Analysis)을 통하여 현재 제공되고 있는 수상택시 서비스에 대한 이용자 측면의 서비스 특성을 분석하고, 이에 대한 시사점을 제시한다. 종합적인 서비스 측면의 IPA 결과, 첫째, 중점개선항목으로 경제성에 대한 부분이 나타났다. 둘째, 개선요망항목으로 접근성, 정보성, 편리성, 현상유지 항목으로 나타났으며, 안전성과 정시성은 노력지속 항목으로 평가되었다. 셋째, 현상유지 항목으로는 친절성과 쾌적성으로 나타났다. 이러한 종합적인 측면의 결과를 바탕으로 수상택시 이용자의 서비스특성을 판단해 보면, 이용자의 경제적 부담에 대한 부분이 가장 시급한 것으로 나타났다. 접근성 즉, 연계교통수단에 대한 부분과 수상택시를 이용할 수 있는 표지판 및 편리성에 대한 부분이 개선되어야 하는 것으로 나타났다. 분석결과를 종합하여 투자우선순위 선정시 한정된 예산을 바탕으로 경제성, 접근성, 정보성, 편리성을 시급히 개선해 준다면 이용활성화에 어느 정도 기여가 가능할 것이라 판단된다.

  • Lately, in consumers' markets the number of new items is rapidly increasing at an overwhelming rate while consumers have limited access to information about those new products in making a sensible, well-informed purchase. Therefore, item providers and customers need a system which recommends right items to right customers. Also, whenever new items are released, for instance, the recommender system specializing in new items can help item providers locate and identify potential customers. Currently, new items are being added to an existing system without being specially noted to consumers, making it difficult for consumers to identify and evaluate new products introduced in the markets. Most of previous approaches for recommender systems have to rely on the usage history of customers. For new items, this content-based (CB) approach is simply not available for the system to recommend those new items to potential consumers. Although collaborative filtering (CF) approach is not directly applicable to solve the new item problem, it would be a good idea to use the basic principle of CF which identifies similar customers, i,e. neighbors, and recommend items to those customers who have liked the similar items in the past. This research aims to suggest a hybrid recommendation procedure based on the preference boundary of target customer. We suggest the hybrid recommendation procedure using the preference boundary in the feature space for recommending new items only. The basic principle is that if a new item belongs within the preference boundary of a target customer, then it is evaluated to be preferred by the customer. Customers' preferences and characteristics of items including new items are represented in a feature space, and the scope or boundary of the target customer's preference is extended to those of neighbors'. The new item recommendation procedure consists of three steps. The first step is analyzing the profile of items, which are represented as k-dimensional feature values. The second step is to determine the representative point of the target customer's preference boundary, the centroid, based on a personal information set. To determine the centroid of preference boundary of a target customer, three algorithms are developed in this research: one is using the centroid of a target customer only (TC), the other is using centroid of a (dummy) big target customer that is composed of a target customer and his/her neighbors (BC), and another is using centroids of a target customer and his/her neighbors (NC). The third step is to determine the range of the preference boundary, the radius. The suggested algorithm Is using the average distance (AD) between the centroid and all purchased items. We test whether the CF-based approach to determine the centroid of the preference boundary improves the recommendation quality or not. For this purpose, we develop two hybrid algorithms, BC and NC, which use neighbors when deciding centroid of the preference boundary. To test the validity of hybrid algorithms, BC and NC, we developed CB-algorithm, TC, which uses target customers only. We measured effectiveness scores of suggested algorithms and compared them through a series of experiments with a set of real mobile image transaction data. We spilt the period between 1st June 2004 and 31st July and the period between 1st August and 31st August 2004 as a training set and a test set, respectively. The training set Is used to make the preference boundary, and the test set is used to evaluate the performance of the suggested hybrid recommendation procedure. The main aim of this research Is to compare the hybrid recommendation algorithm with the CB algorithm. To evaluate the performance of each algorithm, we compare the purchased new item list in test period with the recommended item list which is recommended by suggested algorithms. So we employ the evaluation metric to hit the ratio for evaluating our algorithms. The hit ratio is defined as the ratio of the hit set size to the recommended set size. The hit set size means the number of success of recommendations in our experiment, and the test set size means the number of purchased items during the test period. Experimental test result shows the hit ratio of BC and NC is bigger than that of TC. This means using neighbors Is more effective to recommend new items. That is hybrid algorithm using CF is more effective when recommending to consumers new items than the algorithm using only CB. The reason of the smaller hit ratio of BC than that of NC is that BC is defined as a dummy or virtual customer who purchased all items of target customers' and neighbors'. That is centroid of BC often shifts from that of TC, so it tends to reflect skewed characters of target customer. So the recommendation algorithm using NC shows the best hit ratio, because NC has sufficient information about target customers and their neighbors without damaging the information about the target customers.

  • 협력적 여과 시스템에서 대부분의 사용자들은 모든 아이템에 대하여 선호도를 평가하지 않으므로 인하여 사용자~아이템 행렬은 희박성을 나타내며, 또한 사용자가 평가하지 않은 아이템으로부터 결측치가 발생한다. 일반적인 결측치 예측 방법은 특정 대상의 사용자가 평가하지 않은 결측치를 이 사용자와 비슷한 흥미를 갖는 사용자들의 평가값을 기반으로 예측하나, 기본 평가값 예측 방법은 사용자-아이템 렬의 결측치를 특정 사용자가 아닌 전체 사용자에 대하여 예측한다. 기본 평가값 예측 방법 중 가장 많이 사용되는 방법은 아이템 평균이나 사용자 평균을 이용한 방법이다. 그러나 이 방법은 아이템이나 사용자의 특성, 또한 데이타 집합의 분포 특성을 전혀 고려하지 않는다는 문제점을 갖는다. 본 논문에서는 이러한 문제점을 해결하기 위하여 데이타 집합에 나타난 사용자의 변동 계수를 이용하는 기본 평가값 예측방법을 제안한다. 제안한 방법에서는 수식을 이용하여 자동적으로 사용자 변동 계수의 임계값을 선택하고, 그 임계값에 따라 사용자 평균에서 아이템 평균으로 전환하여 사용자들의 결측치에 대한 기본 평가값을 결정한다. 그러나 사용자 변동 계수들의 분포 정보로 인하여 사용자 변동 계수와 임계갈이 항상 일정한 관계를 유지하는 것이 아니므로, 제안된 방법에서는 임계값을 선택하기 위하여 사용자 변동 계수의 평균과 변동 계수의 분포 정보를 병합한다. 제안된 방법은 사용자가 영화에 대하여 평가한 MovieLens 데이타 집합을 대상으로 평가되었으며, 기존의 기본 평가값 예측 방법보다 그 성능이 우수함을 보인다.
