Social area of children moves to school from family. Attachment to parents of children influences Adaptation of new environment. Development and adaptation of whole life are based on attachment that was formed the early days period of life. This study aims at finding out how are the factors like Relationship between Attachment to parents and Adaptation to school life of children. The targets of the study are 260 kids of the 1st grade and the 2nd grade that are collected at primary school of K city in Jeonlabuk-Do. As for measurement tool that was used for this study, it used the questionnaire for parents Attachment which OK Jeong(1997) adopted from IPPA-R that was manufactured by Armsden & Greenberg(1987), and the questionnaire on adaptation to the school life made by Byung soo, Min(1991), and it found means(M), standard deviation(SD) as for the collected data, and it practiced three way ANOVA, correlation analysis, and Multiple regression. The result of this study was as follows. First, the girls were more attached to father than Boys. According to the contents, alienation to father of boys is higher than that of girls. Also, grade of children and employment or unemployment of mothers factors mutuality effect had significant differences in the area of alienation. Second, the children's attachment to mother that the Kids perceived in total has significant differences statistically according to gender of children and employment or unemployment of mothers factors mutuality effect. Boys of unemployment of mothers and girls of employment of mothers are more attached to mother. Third, the children's attachment to parents showed significant positive correlation in the area of the adaptation to school life. The dimension of communicate, by fathers were shown to affect largely to the adaptation to school life of the kids and among the sub-areas of attachment to fathers, the dimension of confidence by parents were shown to affect largely to the adaptation to school life of the kids. As we saw the study result above, we could confirm that children's attachment to parents had significant relations with the adaptation to school life of the kid, and furthermore, those were affecting importantly to the adaptation to school life the kid. So, we could know that it is important for parents and children to attach mighty so that can be increased adaptation to school life of the kids.

An efficient application method of XML schema matching technique to the document structure of structural calculation document (SCD) of bridge is proposed. With 30 case studies, a parametric study on weightings of name, sibling, child, and parent elements of XML scheme component that are used in the similarity measure of XML schema matching technique has been performed, and suitable weighting to analyze document structure of SCD is suggested. A simplified formula for quantification of similarity is also introduced to reduce computation time in huge scale document structure of SCDs. Numerical experiments show that the suggested method can increase the accuracy of XML schema matching by 10% with suitable weighting parameters, and can maintain almost the same accuracy without weighting parameters compared to previous studies. In addition, computation time can be reduced dramatically when the proposed simplified formula for the quantification of similarity is used. In the numerical experiments of testing 20 practical SCDs of bridges, the suggested method is superior to previous studies in the accuracy of analyzing document structure and 4 to 460 times faster than the previous results in computation time.

철강 구조물의 용접기술에 있어 용접부의 신속성을 좌우하는 가장 중요한 요소는 용접균열에 관한 문제와 용접본드부의 취화에 관한 문제로 요약될 수 있다. 일반적으로 용접부 및 그 근방의 금속은 국부적으로 매우 높은 온도까지 급열된 후 급냉되므로, 용접부에서 각종균열의 발성 위험성이 높아지고 용접본드부를 취화하여 파양인성의 저하를 초래하게 된다. 따라서 이러한 문 제점을 극복하기 위해서는 재료의 선택이나 설계, 시공, 검사의 각 단계에서 충분한 검토가 필 요하다. 특히 최근 들어 이전보다 높은 강도의 고장력강재가 널리 사용되고 구조물의 대형화에 따라 구속조건이 증대되며 구조물의 사용 조건은 더욱 가혹 화함에 따라 상술한 문제점은 더욱 중요시되고 있다. 철강 용접부에 발생하는 균열은 용접시공시 발생되는 균열과 용접완료후 구 조물 사용중에 발생되는 균열로 대별될 수 있다. 용접시공중 발생되는 균열은 용접열싸이클로 인해 생성되는 조직, 석출물등의 치금학적 요인과 잔유응력 또는 구속응력등의 역학적 요인이 중첩됨으로서 발생된다. 또한 사용중 발생되는 균열은 상기의 두 가지 요인이외에 환경적 요인이 첨가되어 발생된다고 볼 수 있다. 이상과 같은 용접균열을 방지하기 위해서는 실 구조물 용접 조립시의 각종 조건을 재현한 시험법을 통해 용접균열 발생의 한계조건을 정량적으로 분석할 필요가 있다. 이러한 균열 시험의 결과, 적정한 용접 시공 조건이 도출될 수 있기 때문이다. 이와 같은 필요성에 의해 지금까지 다수의 용접균열 시험법에 관한 연구가 행하여져 왔고 그 중에는 각 국가의 협회나 학회의 규격으로 확립된 것도 많으며 국제규격으로 되어 있는 것도 있다. 본 고에서는 각종균열들에 대한 지금까지 밝혀진 기구들에 대해 해설하고, 그 각각에 적용되고 있는 시험법들에 대해 소개하고저 한다.C1지구의 공업.생활용수는 103units, 33units로 배분되고, 하류지구에 304units로 배분되었다. 따라서 용도별로 물배분하므로서 금호강 하루지역에 더욱 많은 물을 배분할 수 있음을 알았다.통해서 수위-유량관계(rating curve)를 규명하였다. 시험지구의 관개효율 및 용수손실 규명 등에 관한 기본자료를 수집하기 위해서는 계측시스템의 운영은 장기간으로 지속 되어야 한다며, 전기전도도와 토양수 농도, 전기전도도와 함수량의 관계를 이용한 천이상태의 오염원 농도 측정방법을 개발하였다. 특히 제안식에서는 한계함수량의 개념을 도입하여 전기전도도와 함수량관계를 추정하므로 추정식의 실험값 반영 정도를 증가시켰다. 본 연구에서 제안된 식을 이용하여 추정된 전기전도도와 함수량관계는 다른 제안식에 비하여 개선된 결과를 보여 주었고, 본 연구에서 개발한 오염원 농도 측정법을 이용하여 측정한 결과 함수량이 0.15이하에서는 측정오차가 크지만 함수량이 0.15이상일 경우 매우 좋은 결과를 보였는데 질량평형을 검토한 결과 약 5-10%의 오차율을 보였다. 따라서 본 논문에서 개발된 천이상태의 오염원 농도측정법은 용존 오염물질의 이송에 관한 정확한 실험을 제공할 것으로 판단된다.며, 수질 보전적-환경 보전 차원에서 저수관리 체계를 확고히 할 수 있는 방안을 강구하여야 할 것이다.펄스주입법에 의해 증착된 박박은 강유전성 이력을 나타내었다.지역과 비도시지역을 비교하는 조사 연구가 필요하며, 이러한 조사결과를 바탕으로 자녀의 식습관에 대한 교육을 위한 교재, 교구의 개발과 영양, 식습관 교육프로그램의 개발을 통해 가정과 학교에서 부모와 교사가 자녀의 식생활 지도 관리를 돕고 가정과 교육기관이 연계한 교육 프로그램이 활성화 될 수 있도록 지속적인 관심을 기울여 나가야 할 것이며, 이에 따른

Mobility management is one of the most important research issues in 6LoWPAN, Since the IP-WSN application domain is expanded to real-time applications such as healthcare and surveillance systems, a fast and seamless handover becomes an important criterion in 6LoWPAN. However, a draft of IETF 6LoWPAN WG for mobility support does not decrease handover delay. Although LoWMob supports a fast intra-PAN handover. it can be supported when the infrastructure node has the location information of the other nodes in the mobile node's moving direction. In this paper, we propose a fast and seamless mobility protocol to support intra-PAN handover, named intra-MARIO. In intra-MARIO, a parent node of the mobile node preconfigures its handover to the PAN when the parent node detects its movement, thereby reducing the handover delay. Since intra-MARIO also supports route optimization, the mobile node can communicate with its corresponding nodes through the optimal route. In this paper, we analysis the signaling cost and evaluates that the handover can be completed in 20ms by simulation.

The authors investigated the relationship between the response to the external stimulation and ability of verbal behavior in the patients with somatoform disorder who have pain. The subjects consisted of 34 patients(male 10, female 24) and 37 normal controls(male 19, female 18). Pressure pain thesholds were measured by algometer and alexithymia was assessed by Toronto Alexithymia Scale(TAS). Somatization Scale of SCL-90R and Parental Bonding Instrument were also used. It was shown that 82.4% of the patients had chronic somatic complaints. The mean values of TAS, degree of somatic symptoms and pressure pain thresholds were significantly higher in the patient group than in the normal controls. 44.1% of the patients was considered alexithymia group and there was no correlation between scores of alexithymia and value of pressure pain thresholds. In conclusion, the patients with somatoform disorder who had pain were dull in pain perception to external physical stimulation. This result suggested that their low perception of pain could be closely related with chronicity of illness. And the Poverty of verbal expression of inner emotion was suggested to be one of the factors affecting somatization and difficulty in psychotherapy.

The subjects of this study are three visually-impaired undergraduates currently considering if they should take a leave of absence after finishing the first year in S University located in Busan City. From March to July, 2018, this researcher explored the meaning of their university entrance and the essential meaning and structure of their school life experiences by using Giorgi's phenomenological methodology. According to the results, this author drew 32 meaningful statements and also 10 main themes, "the excitement of campus life and the name of being an undergraduate", "parents' suggestion", "something other than being a massager", "Is it a place that anyone can enter? Or, is it a special place?", "loneliness within the public", "Everything is an obstacle.", "It's not giving up, but still I am in a vague moment.", "the beginning of another conflict", and "studying in a university is not for the present but for the future". They were categorized into being a university student and the meaning of it (category1), adaptation to university life and reality (category 2), and one year after the entrance: the meaning of being a university student (category 3). Based on the above results, this author intends to provide foundational material about what universities can do for visually-impaired students to adapt to university life in the initial steps properly.

The purpose of this study was to compare the degree of happiness between mothers of preschoolers (3-5yrs) and mothers of elementary school students (6-7yrs). The subjects of this study included 168 mothers of preschoolers and 170 mothers of elementary school students. They were randomly chosen. We measured and analyzed 338 mothers' happiness using Ryff's psychological well-being items. The results of this study reveal that although overall happiness level was similar, the two groups of mothers' happiness had statistically significant differences in 6 factors of mothers' happiness. Preschooler mothers had higher levels of happiness in autonomy and personal growth, while elementary school student mothers had higher levels of happiness in environment mastery, positive relationships, purpose of life, and self-acceptance. Also, the background of mothers, such as age, educational status, family income, and religion caused statistically significant differences in happiness level of both groups.

In this study, seismic resistance of concrete encased U-shaped steel beam-to-steel H-shaped column connections was evaluated. Three specimens of the beam-to-column connection were tested under cyclic loading. The composite beam was integrated with concrete slab using studs. Re-bars for negative moment were placed in the slab. The primary test parameter was the details of the connections, which are strengthening and weakening strategies for the beam end and the degree of composite action. The depth of the composite beams was 600mm including the slab thickness. The steel beam and the re-bars in the slab were weld-connected to the steel column. For the strengthening strategy, cover plates were weld-connected to the bottom and top flanges of the steel beam. For the weakening strategy, a void using styrofoam box was located inside the core concrete at the potential plastic hinge zone. The test results showed that the fully composite specimens exhibited good strength, deformation, and energy dissipation capacities. The deformation capacity of the beam exceeded 4% rotation angle, which is the requirement for the Special Moment Frame.

This study examined the longitudinal relationship between paternal depressive symptoms and maternal depressive symptoms simultaneously. This study also identified the interplay of paternal and maternal depressive symptoms for predicting elementary children's language development, their problem behaviors and their school adjustment. Using the data from the Panel Study on Korean Children for the 4th-8th years (2011~2015 year), this study used the Latent Growth Curve Model, which is helpful for examining longitudinal relationship differences among variables. The sample subjects were 1,754 parents and children. The results are as follows. The initial level of paternal depressive symptoms had a positive impact on the rate of change in maternal depressive symptoms. The initial level of maternal depressive symptoms had a negative impact on the rate of change in maternal depressive symptoms. Mothers' depressive symptoms showed not only the mothers' own depression problem. but also the self-effect and counterpart effect of depression on the fathers' depression problem. The rate of change in maternal depressive symptom mediated the relation between the initial level of parental depressive symptoms and children's receptive language, internalizing/externalizing problems, and school adjustment. Therefore, depression prevention and intervention programs for both fathers and mothers are needed for the healthy development and school adaptation of school-age children.
