An assembly modeling system, with which a designer can interactively create an assembly of components ready for the dynamic analysis, has been developed. In this system, an assembly model is created from the mating conditions between the components in the assembly, and then most information required for the dynamic or kinematic analysis packages are derived. For this development, the following problems have been solved; the creation of assembly data structure, the derivation of the joint information, the inference of each component's position, and the creation of the joint coordinate systems. Through this work, the designer can easily model an assembly by assigning mating conditions, and check the dynamic or kinematic performance with the automatic creation of inputs for the assembly analysis packages.

A random chat application is a type of social dating application that helps people find a lover or spouse by randomly connecting and providing services such as text, voice and video chat. Recently, there has been globally a rapid increase in its use due to the fact that it provides people to quick and convenient encounters at low cost. However, it is used as one of method to prostitute or to trade drugs and become a cause of violent crimes due to various criminal occurring after actual meeting between app users. For this reason, a random chat application is likely to provide proof of prostitution or drug trade and clues to arrest rape, kidnapping and murder suspects. Thus, it is necessary to analyse random chat applications from the viewpoint of digital forensics investigation, but there is no related research at all. Therefore, in this paper, we analyzed artifacts of 6 Korea random chat application's user behaviors; Ranchat, AngTalk, SsumgThing, DaTalk, EveryTalk and Sail. As a result, we found that it is remain on mobile device that time and contents of message transmission/reception, sender/receiver, friend profile and user account creation time when user is using the applications.

The ship's seakeeping performance in the pitching and roll motion was felt tired. These gives structural loads to loaded with cargo and hull facilities. Be to improve, small catamaran power yacht designed a data for ship research and ship's hull form to be decided. In this study, based on domestic release for coastal marine environment in the interpretation criteria were chosen based on the exercise performance. The seakeeping performance of marine leisure catamaran was based on voyage speed. The seakeeping performance estimates based on the encounter angle, the wave of the encounter frequency response amplitude ratio for exercise was assessed in the high performance area.

This study focused on analysis of experience for adults' reunion with original family members who had lived in child care facilities during the childhood and adolescence. It was researched based on the grounded theory from nineteen participants have interacted with their own separated family members for more than ten years after had been reunited with them. As written in the result section of the study using the paradigm model analysis showed that it was caused by feel regret by reunion, absence of belonging and repeated abandoned wound. The contextual condition appeared as sensitive memories as wounded and frustration of compensation mentality. The centralization phenomenon came in a whirlpool of emotion. The intervention condition appeared as recognition of filial piety, support system for parents and healing their parents mind. The action-interaction showed up as revenge with good will, setting own boding free, inspire of own pride, family reconciliation. The consequence appeared as family sublimation, successful execution of life task and getting living foundation. This research made practical and political proposals based on above result and described the limitations of the study and the proposals for the latter study.

The purpose of this research is to try to enrich human life by applying the convergence energy of humanities and science to modern poetry. "Communication and entertainment", as modern poetry with modernist aesthetics, must indulge people's lives, which is simply to live happy lives. Entertainment is especially crucial because it is a method through which people can lead humane and satisfactory lives. The prerequisites for achieving this are true liberty and happiness. If these two prerequisites derive from humanity's consciousness, "communication and entertainment" can be born from "convergence of information technology and modern poetry", as the author insisted.

The purpose of this study was to obtain basic information for novice teachers' adjustment. The data from five novice teachers were collected by in-depth interviews of each subject, as well as reviewing a memo diary, journal and class diary. The results indicated that the novice teachers' experiences were categorized into difficulties in social relationships, heavy workload, stress related to making mistakes, obtaining support and assistance, adequate understanding of their field of work and so on. The model theory for their process of adjustment was found by grounded theory approach. The causal conditions include mistakes in performance of work and immaturity of managing social relationships. The contexts include age of the children, work conditions(i.e. time and space), amount of workload, unfamiliarity of new work assignments, personalities of colleagues, and high frequency of meeting parents of children. The intervening conditions are composed of a guidance program for novice teachers, support from colleagues, work rewards, and the personalities of novice teachers. The novice teacher use three strategies: trying to ignore, sharing difficulties and accessing support from friends or family, as well as willful efforts to transfer negative emotions into positive ones. The consequences of the strategies include: successful career progression, survival, and desire for leaving the field of work.

This study attempted to reveal the essential meaning of happy life for non-disabled children with disabled parents through a phenomenological research method for non-disabled children with disabled parents using welfare centers. As a result, 76 meaningful statements related to a happy life, eight categories of 20 topics have been drawn up, and the essential meaning of a happy life for a child is 'a happy life for parents', 'a life where parents are recognized' and 'a life where parents are no different from other families,' and 'a life where a child is living happily' as an 'economically stable life' and 'a life with disabilities' As such, I believe that since this period is important for children, there is a pressing need for ways to intervene and improve awareness of the disabled and the role of life.

People who spend more time alone tend to report higher levels of loneliness. However, whether people experience loneliness in solitude can differ The current research investigated the role of a sense of power as a predictor of loneliness among people who lack social interaction. investigated factors predicting loneliness in people with little social time large-scale survey data. As a result of discriminant analysis, a sense of power was verified as a factor that lonely non-lonely groups. a sense of power As a result, a causal relationship between a sense of power and social loneliness was confirmed. When people feel alone, a high sense of power can work as a buffer against loss of belongingness and the experience of social loneliness. This research focused on psychological rather than situational factors to alleviate loneliness in the current situation where social encounters are limited due to the increase of single-person households and the 19 pandemic.
