지금까지 사용성과 관련된 웹 이용행위에 대한 예측이나 분석은 사용자의 인구통계학적 특성이나 사용정황의 특성만으로 주로 설명되어 왔다. 그러나 그러한 특성만이 행위를 유발하늑 요인으로 볼 수 있는지, 그렇지 않다면 어떠한 요인이 있으며 또한 그러한 요인들은 행위에 어떠한 특성을 유발할 것인지에 대한 의문으로 본 연구를 진행하였다. 이는 사용자 중심의 사용자인터페이스(UI)디자인에서 사용자 특성을 정의하는데 중요한 요소로 활용되었던 사용자정보(User Profile)를 사용에 있어서의 특정유형과의 상관관계를 포함하는 사용자정보(User Profile)로 확장시킴으로써 구체적인 사용자인터페이스(UI)디자인에 적용될 수 있도록 하기 위함이다. 연구내용은 첫째, 다양한 미디어에 따른 사용자를 이해하고 기존의 사용자 분류 방법을 고찰한다. 둘째, 웹 이용행태에 따른 사용자 분류를 위한 사용자 분류변수 및 변수 측정 척도를 마련하고 사례 연구를 통해 사용자 행위 특성을 추출하여 특성에 따른 사용자를 분류한다. 셋째, 실험을 통해 수집된 데이터를 바탕으로 분류된 사용자 집단의 사용자정보(User Profile)의 특성을 밝혀 사용자정보(User Profile)의 특성이 유발하는 행위의 요인을 규명하기 위해 행위 특성과 사용자정보(User Profile)의 특성을 맵핑시켰다. 이를 통해 사용자의 이용행태에 따른 특성이 사용자정보(User Profile)특성 중 사용자의 일반 정보와 사용정황 뿐 아니라 개인성향이나 매체 사용태도와 성격유형 등도 영향을 끼칠 수 있다는 가능성을 발견할 수 있었다. 실험 설계상의 몇 가지의 문제점들이 발견되었으나 이를 개선하고 보완한다면 좀 더 명확한 사용행위에 따른 사용자정보(User Profile)특성을 추출할 수 있을 것이다. 따라서 사용자정보(User Profile) 특성으로도 사용자의 행위 유형을 예측할 수 있어 사용자 분류를 활용한 사용자인터페이스(UI)디자인의 가능성을 확대시킬 수 있을 것이다.

The three-dimensional profile of a solder fillet is predicted by minimizing the surface tension and gravity energies of the solder joint using finite element modeling. Geometric complexity stemming from the inclined plane of the gullwing lead is resolved by employing three element types. These element types are used to describe the joint profile formed on the vertical, inclined and interfacial planes. The predicted solder joint profiles show good agreements with the experimental data provided that the solder volume is adjusted considering the wicking effects. Effects of the pad length, inclined lead angle and solder volume on joint profiles are also investigated.

Purpose: The purpose of this research is, by investigating organizational characteristics, types of nursing organizational culture and team effectiveness in ICU, to ascertain the type of nursing organizational culture and the organizational characteristic that can improve the team effectiveness. Method: The research targeted 427 nurses from 33 ICUs of 14 general hospitals which have more than 250 beds and the data were gathered by using self-report questionnaires from April 10, 2003 to April 24, 2003. For this research, the following tools were used; the tool for measuring organizational characteristics and organizational cultures and the tool for measuring team effectiveness. Result: The most significant nursing organizational characteristic in ICU is the centralization. The organizational culture in ICU is generally rank-oriented culture. There was a significant difference (p<.01) in four types of organizational cultures; relation-oriented, innovation-oriented, rank-oriented and task-oriented. Verifying influence power of organizational cultures upon team effectiveness of ICU, relation-oriented culture had 49.2% of an influence upon team effectiveness, innovation- oriented and relation-oriented culture had 60.4% of an influence, and rank-oriented, innovation-oriented and relation-oriented culture had 61.2% of an influence. The organizational culture profiles according to the types of nursing organizational cultures in 33 ICUs were found by a cluster analysis. They were classified into five culture profiles; strong balance culture profile, weak balance culture profile, innovation-oriented and task-oriened culture profile, strong relation culture profile and strong rank culture profile(p<0.5). According to me organizational culture profiles, a significant difference of team effectivenesses(coworker satisfaction, team performance perception, team satisfaction and team commitment) was found(p<.01). The strong balance culture profile had the best team effectivenesses. Conclusion: For nursing culture management, a nursing administrator should identify the relevant nursing organizational culture at first by utilizing an innovative team-leader. After identifying the organizational culture, the administrator should make strategic plans and practices that can distinguish good organizational cultures to be expanded from ones to be sublated so that a strong balance culture can be developed.

This study identified and compared family values within and across different generations concerning gender roles, attitudes toward diverse families, children, and parental roles. Data were obtained from the 2020 Seoul Family Report Survey. There were 1,949 study subjects, including first- and second-generation baby boomers and individuals in generations X, Y, and Z in Korea. Latent profile analyses were conducted using M-plus. Perceptions and views concerning family values were classified into different types. The main findings were as follows. Two types were identified among first baby boomers, and three were identified among second baby boomers. Most of the first and second baby boomers belonged to the "moderate" type. Two types were detected among those in Generation X. Regarding gender roles, most views of Generation X were slightly progressive, while their other family values were more moderate. Three types were identified among those in Generation Y: "progressive," "moderate," and "very liberal." Generation Z was identified as a "progressive" group. This study provides basic data to explore the direction of the coexistence of generations by identifying and comparing diverse family values within and across generations.

This study deals with the correction of gear tooth profile error by finish roll forming. First, we experimentally confirmed that the tooth profile error is a synthesis of the concave error and the pressure angle error. Since various types of tooth profile errors appear in the experiments, we introduced evaluation parameters for rolling gears to objectively evaluate profile quality. Using these evaluation parameters, we clarified the relationship among the tooth profile error, the addendum modification factor (A. M. factor), and the tool loading force. We verified the character of concave error, pressure angle error, tool loading force and number of cycles of finish roll forming by using a forced displacement method. This study makes clear that tool loading force and number of cycles of finish roll forming are very important factors that affect involute tooth profile error. The results of the experiment and analysis show that the proposed method reduces concave and pressure angle errors.

This study suggests modular composite profile beams, where the prefab concept is applied to existing composite profile beams. The prefab concept produces a beam of desired size having two types of profile: side module and bottom module. Module section will improve construction efforts because it offers several benefits : reduction of deflections due to creep and shrinkage, which might be found in existing composite profile beams; increase in span/depth ratio; and free prefabrication of any required beams. Based on the established analysis theory of composite profile beams, an analysis theory of modular composite profile beams was suggested, and analysis values were compared with experimental ones. The behavior of individual modules with increase of load was measured with a strain gauge, and the shear connection ratio between modules was analyzed by using the measured values. As a result of experiment, it was found that theoretical flexural strength on condition of full connection was 57%-80% by connection of modules for each specimen, and it is expected that flexural strength will approximate the theoretical levels through further module improvement.

A numerical method is proposed to synthesize automotive cam profiles. An arbitrary acceleration profile for the cam follower motion is divided into several segments, each of them is described by a Hermite curve. A cam profile is defined by control point locations and control variables assigned to each segment. Closed form equations are derived for velocity and displacement constraints which should be satisfied for the curve to be a cam profile. Because the method is flexible and provide arbitrary local controllability, any types of cam acceleration profile can be reproduced by the method. The method is expecially useful for the design of roller type OHC valve trains which need precise local control in the cam profile design to avoid under-cutting problems.

The purpose of this study is to analyze the types of latent profiles of high school students' fire safety awareness and to identify the characteristics of related variables. For this purpose, a survey was conducted from March 22 to May 25, 2021 for 1054 high school students (male; 569, female; 485) in 3 cities, in Jeollabuk-do. The latent profile was analyzed using a scale consisting of 4 sub-factors: 'fire prevention', 'fire preparedness', 'indirect fire response', and 'direct fire response'. It was checked whether there were differences according to the inter-individual differences of the latent group. As a result of the analysis, fire safety awareness of high school students was classified into three latent profiles. The three groups were named 'High Perception Type', 'Moderate Perception Type', and 'Low Perception Type' according to their types. In fire safety awareness, there is a significant difference in the individual differences according to the gender and academic achievement of the latent profile. These results are meaningful as the first study to analyze the latent profile of high school students' fire safety awareness, and it is also meaningful to provide a useful basis for the contents and methods of customized fire safety education by identifying the tendencies of spontaneous groups and their fire safety awareness.

The purpose of this study is to interpret the semantic actions of body image symbolized in body expression images shown by micro-influencers body profiles to understand the body profile phenomenon of the MZ generation. As a result of collecting body profile data from micro-influencers, the body profile image types of female influencers on SNS were classified into four types, Athletic, Slim body, Natural, and, Glamorous. Images representing each type were analyzed using the Roland Barthes' Myth model analysis frame. As a result of the semantic analysis, influencers were found to be very active and bold, emphasizing certain body parts according to the type of body image they pursue. Fashion is strategically used to emphasize these aspects. It was found that the ideology of a 'subjective modern woman' was commonly expressed through emphasis on visual signs. This study is meaningful in that it can indirectly lead to the understanding the fashion culture expressed by the MZ generation and provide consumer information and essential data that can be used for communication strategies in the fashion market.
