The purpose of this study is to examine the importance of healthy attachment formation by examining the effects of dental hygiene students' adult attachment patterns on depression, self-esteem, empathy, and career choice, and to present basic data for career guidance that considers individual characteristics. Students enrolled in the dental hygiene department at a university in Daejeon were the subjects of this study, and data were collected from September 14 to October 14, 2020 through self-reported questionnaires. Frequency analysis, ANOVA, correlation analysis, and multiple regression analysis were performed. As a result of classifying adult attachment styles into three types, out of a total of 158 people, 62 (39.2%) had the avoidant attachment style, 56 (35.4%) had the secure attachment style, and 40 (25.3%) had the anxious-ambivalent attachment style appear. Self-esteem according to attachment type (F=26.224, p<0.0001), empathy (F=3.944, p<0.05), depression (F=12.702, p<0.0001), career indecisiveness (F=4.367, p<0.05). Based on the results of identifying the sub-factors that affect the dental hygiene and adult attachment styles of students with depression, self-esteem, empathy and career choice, this study intends to use them as reference materials for career decision taking into account individual characteristics.

본 연구는 2011년 2월 10일부터 2011년 3월 2일까지 서울지역 특급호텔 조리종사자를 대상으로 실시하였으며, 총 161부에 대하여 SPSS 17.0을 이용하여 요인분석과 신뢰성 검증을 실시하고 제시된 연구가설을 검증하기 위해서 다중회귀분석을 실시하였다. 분석결과 첫째, 대인애착, 직무만족과 직무애착 간의 상관관계를 조사한 결과 안정형 애착은 직무만족과 직무애착에 유의한 정(+)의 상관관계가 있는 것으로 나타났다. 둘째, 불안형 애착은 직무만족에 부(-)의 상관관계를 보였다. 그리고 애착 유형에 따라 직무만족과 직무애착과의 상관관계가 없는 것을 확인할 수 있다. 셋째, 대인애착이 직무만족에 미치는 영향을 분석할 결과 안정형은 직무만족에 유의한 정(+)의 영향을 미친 반면에, 회피형과 불안형은 직무만족에 유의적인 영향을 미치지 못하는 것으로 나타났다. 따라서 이와 같은 분석결과를 바탕으로 외식조리종사자의 유용한 시사점을 제시하였다.

This study was conducted as a basic study for the selection of tags suitable for logistics management in the palletized unit-load unit and the development of various technologies to activate the palletized unit-load shipment of agricultural products through local APCs. Three types of passive RFID tags of UHF 900 MHz and one type of active RFID tag of 2.4 GHz band designed and manufactured through this study were used to analyze the receiving strength according to the tag's attachment location and distance of the palletized unit-load of agricultural products. In the passive RFID tag, there was a large difference in receiving strength by the tag's attachment location and a large amount of data loss depending on the distance within 30 m, whereas, in the active RFID tag, it was superior to the passive tags in terms of both receiving strength and data loss. Therefore, active tags are desirable from the perspective of multiple identification of warehouses with large spaces in relation to the application of RFID tags for palletized unit-loads of agricultural products, but the development of low-power technologies such as software wakeup power management as well as hardware to minimize battery power consumption is necessary.

Many vibrating mechanical systems from the real life are modeled as combined dynamical systems consisting of beams to which spring-mass secondary systems are attached. In most of the publications on this topic, masses of the helical springs are neglected. In a paper (Cha et al. 2008) published recently, the eigencharacteristics of an arbitrary supported Bernoulli-Euler beam with multiple in-span helical spring-mass systems were determined via the solution of the established eigenvalue problem, where the springs were modeled as axially vibrating rods. In the present article, the authors used the assumed modes method in the usual sense and obtained the equations of motion from Lagrange Equations and arrived at a generalized eigenvalue problem after applying a Galerkin procedure. The aim of the present paper is simply to show that one can arrive at the corresponding generalized eigenvalue problem by following a quite different way, namely, by using the so-called "characteristic force" method. Further, parametric investigations are carried out for two representative types of supporting conditions of the bending beam.
