The Relationship between Empathy and Self-Acceptance of College Students and Adaptation to College Life

Hyunjae Cho(Hyunjae Cho) J-INSTITUTE 2022 Public Value Vol.7 No.2

Purpose: The successful adaptation of students to college life is an important factor that significantly influ-ences success or failure in life after college as well and it also correlates with the success or failure of important periods of life. Therefore, although many researchers have studied adaptation to college, so far studies have mainly focused on academic adaptation. However, as adaptation to college life includes not only academics but also various factors such as interpersonal relationships and emotional adaptation, it is also important to shed light on the relationship between variables other than academics and college life adaptation. This study aims to reveal important information that helps college students adapt to school by examining in detail how empathy and self-acceptance affect adaptation to college life. Method: Questionnaires about empathy, self-acceptance, and adaptation to college life were administered to 345 college students, and the analyses were performed based on the data of 318 students who answered faithfully. First, a correlation analysis was conducted to confirm the relationship between each variable, and a variance analysis was conducted to see if there were any differences in empathy, self-acceptance, and adaptation to college life according to school year and gender. Finally, in order to comprehensively confirm the relationship between the three variables, AMOS 22.0 was used to analyze the structural equations. Results: The results of the analysis indicated there was a significant correlation between empathy and self-acceptance and adaptation to college life. The results of examining whether there were any significant differ-ences among the three variables according to gender and school year, showed that, in the case of empathy, female students' empathy was higher than that of male students, and there was no difference in self-acceptance according to gender. In the case of adaptation to college life, male students showed higher rates. In terms of differences by school year, there was no difference in empathy and self-acceptance, and there was a significant difference in college life adaptation by school year. Post-hoc analysis(Scheffe method) was performed to confirm specific differences by school year, but no significant differences were found. Examining the relationship between empathy, self-acceptance, and adaptation to college life, empathy had a positive effect on adaptation to college life and self-acceptance. Self-acceptance also had a positive effect on adaptation to college life. Conclusion: This study is intended to specifically elucidate the effect of empathy and self-acceptance on ad-aptation to college life. It was found that empathy and self-acceptance had a positive effect on adaptation to college life as predicted in this study. Also, it was confirmed that self-acceptance had a mediating influence on the effect of empathy on adaptation to college life. The results will be used as important data for various activities to improve adaptation to college life. This suggests that improving empathy and self-acceptance abilities should be included as an important factor in the process of developing a future program for college life adaptation.

The Effect of LEARNED HELPLESSNESS on the Adaptation to College Life

Hyunjae Cho J-INSTITUTE 2021 Regulations Vol.6 No.2

Purpose: College life is perhaps the largest task of college students during the late period of their youth in their developmental phase, which is also a crucial task directly leading to their future satisfaction of life. However, college students in Korea are admitted without a proper preparation due to their academic centric education and blind focus on grades and scores, thereby undergoing much confusion in the process. This paper presents data of importance to help a successful adaptation to college life by clarifying the effect of the learned helplessness formed through the repeated failures on the adaptation to college life in detail. While previous studies have been limited on the effect of the learned helplessness on the learning process, this study seeks to specifically verify the effect on the adaptation to college life. Method: By undertaking reference research, the factors impeding the successful adaptation to college life are identified, while the concept, characteristics, and the basic aspects of the factors are summarized, and how the factors cause a negative effect on the adaptation to college life is clarified in detail. Result: Learned helplessness brings about negative predictions even under new circumstances even while re-peated failures are experienced. The negative expectations formed as such cause the loss of new attempts or practical behaviors, thereby gravely impeding the behavioral practice required for the adaptation to college life. This further causes a serious negative impact on the formation of self identity and career path development. To form the self identity and develop an appropriate career path, one needs to have a positive attitude and find and practice various activities, yet being trapped in the learned helplessness causes passive attitude, negatively im-pacting the achievement of any developmental task. Moreover, learned helplessness causes negative emotions including dpression and anxiety, while impeding the emotional adaptation to college life. Conclusion: As examined throughout this study, it was discovered that the learned helplessness causes a neg-ative impact on the adaptation to college life across various areas. Therefore, colleges and universities ought to actively make efforts for the successful adaptation to college life by rolling out various programs which can help their students address the learned helplessness.

<P>Although structural DNA nanotechnology is a well-established field, computations performed using DNA algorithmic self-assembly is still in the primitive stages in terms of its adaptability of rule implementation and experimental complexity. Here, we discuss the feasibility of constructing an <I>M</I>-input/<I>N</I>-output logic gate implemented into simple DNA building blocks. To date, no experimental demonstrations have been reported with <I>M</I> > 2 owing to the difficulty of tile design. To overcome this problem, we introduce a special tile referred to as an operator. We design appropriate binding domains in DNA tiles, and we demonstrate the growth of DNA algorithmic lattices generated by eight different rules from among 256 rules in a 3-input/1-output logic. The DNA lattices show simple, linelike, random, and mixed patterns, which we analyze to obtain errors and sorting factors. The errors vary from 0.8% to 12.8% depending upon the pattern complexity, and sorting factors obtained from the experiment are in good agreement with simulation results within a range of 1-18%.</P> [FIG OMISSION]</BR>

This paper investigated an optimal belt path for minimizing maximum chest deflection of THOR-M50 dummy. To understand structural characteristics of the thorax region, a series of thorax compression tests were performed. Based on the test results, an optimal belt path, which path through the mid-point of the upper IR-TRACC was suggested. The optimal belt path, then, was verified through belt pull tests. Since the belt pull experiment was performed under a simplified static condition, the validity of the optimum belt path need to be verified under dynamic loading conditions such as sled or vehicle crash tests.

<P>Abstract. Particulate air pollution in the Kathmandu Valley has reached severe levels that are mainly due to uncontrolled emissions and the location of the urban area in a bowl-shaped basin with associated local wind circulations. The AERONET measurements from December 2012 to August 2014 revealed a mean aerosol optical depth (AOD) of approximately 0.30 at 675 nm during winter, which is similar to that of the post-monsoon but half of that of the pre-monsoon AOD (0.63). The distinct seasonal variations are closely related to regional-scale monsoon circulations over South Asia and emissions in the Kathmandu Valley. During the SusKat-ABC campaign (December 2012-February 2013), a noticeable increase in both aerosol scattering (σs; 313 → 577 Mm−1 at 550 nm) and absorption (σa; 98 → 145 Mm−1 at 520 nm) coefficients occurred before and after 4 January 2013. This can be attributed to the increase in wood-burned fires due to a temperature drop and the start of firing at nearby brick kilns. The σs value in the Kathmandu Valley was a factor of 0.5 lower than that in polluted cities in India. The σa value in the Kathmandu Valley was approximately 2 times higher than that at severely polluted urban sites in India. The aerosol mass scattering efficiency of 2.6 m2 g−1 from PM10 measurements in the Kathmandu Valley is similar to that reported in urban areas. However, the aerosol mass absorption efficiency was determined to be 11 m2 g−1 from PM10 measurements, which is higher than that reported in the literature for pure soot particles (7.5 ± 1.2 m2 g−1). This might be due to the fact that most of the carbonaceous aerosols in the Kathmandu Valley were thought to be mostly externally mixed with other aerosols under dry conditions due to a short travel time from their sources. The σs and σa values and the equivalent black carbon (EBC) mass concentration reached up to 757 Mm−1, 224 Mm−1, and 29 µg m−3 at 08:00 LST (local standard time), respectively but decreased dramatically during the daytime (09:00-18:00 LST), to one-quarter of the morning average (06:00-09:00 LST) due to the development of valley winds and an atmospheric bounder layer. The σs and σa values and the EBC concentration remained almost constant during the night at the levels of 410 Mm−1, 130 Mm−1, and 17 µg m−3, respectively. The average aerosol direct radiative forcings over the intensive measurement period were estimated to be −6.9 ± 1.4 W m−2 (top of the atmosphere) and −20.8 ± 4.6 W m−2 (surface). Therefore, the high atmospheric forcing (i.e., 13.9 ± 3.6 W m−2) and forcing efficiency (74.8 ± 24.2 W m−2 τ−1) can be attributed to the high portion of light-absorbing aerosols in the Kathmandu Valley, as indicated by the high black carbon (or elemental carbon) to sulphate ratio (1.5 ± 1.1). </P>

Attitude Control of Agile Spacecraft Using Momentum Exchange Devices

Hyunjae Lee,Shin-Je Cho,Hyochoong Bang 한국항공우주학회 2006 International Journal of Aeronautical and Space Sc Vol.7 No.2

This paper is focused on designing an implementable control law to perform spacecraft various missions using momentum exchange devices such as reaction wheels(RWs) and control moment gyros(CMGs). A compact equation of motion of a spacecraft installed with various momentum exchange devices is derived in this paper. A hybrid control law is proposed for precision attitude control of agile spacecraft. The control law proposed in this paper allocates control torque to the CMGs and the RWs adequately to satisfy the precision attitude control and large angle maneuver simultaneously. The saturation problem of reaction wheels and the singularity problem of control moment gyros are considered. The problems are successfully resolved by using the proposed hybrid closed loop control law. Finally, the proposed hybrid control law is demonstrated by numerical simulations.

파놉티콘의 강화 혹은 역감시?

전현재(Hyunjae Jeon),조주은(Jooeun Cho) 한국사회조사연구소 2015 사회연구 Vol.- No.28

최근 자동차 블랙박스가 확산되면서 블랙박스에 의한 감시가 증가하고 있다. 사람들은 사고 발생시 억울한 일을 당하지 않기 위해 블랙박스를 구입하고, 블랙박스로 자기 자신을 감시한다. 블랙박스 감시는 두 가지 측면에서 파놉티콘 감시와 구분되는 탈파놉티콘 감시의 특징을 지닌다. 하나는 블랙박스가 정보통신기술을 이용하는 디지털화된 감시 도구이며, 다른 하나는 파놉티콘 감시하에서 감시 대상이던 개인이 감시 주체가 되었다는 점이다. 이 연구에서는 블랙박스동호회의 인터넷 게시판을 통하여 사람들이 블랙박스로 무엇을 하는지, 구입 의도대로 자기 보호를 위해서만 블랙박스를 사용하는지, 아니면 다른 용도로도 사용하는지, 그리고 블랙박스가 기존의 감시체제에 어떤 영향을 미치는지를 분석하였다. 분석 결과를 요약하면 다음과 같다. 첫째, 사람들은 블랙박스로 자기 자신, 타인, 보험회사 등 다양한 대상을 감시하면서 감시 주체로서의 정체성을 확립하고 있었다. 구입 목적과는 달리 자기 보호보다 타인 감시에 블랙박스를 더 많이 활용하였다. 둘째, 인터넷 동호회는 일종의 시놉티콘으로 작용하였는데, 일반 대중이 블랙박스 이용의 모델을 제시하고, 여론 형성에 영향을 미쳤다. 셋째, 블랙박스 감시는 ‘신고’ 행위를 통해 감시 어셈블리지에 연결되고, 파놉티콘 감시 권력을 강화시켰다. 넷째, 블랙박스와 그에 의한 신고가 일상화되면서 사람들은 블랙박스감시를 내면화하고, 감시에 대한 사회적 수용도가 높아졌다. 마지막으로 사고발생시 보험회사가 판단한 과실비율에 문제를 제기하는 역감시가 이루어지고 있었다. 즉, 다수가 소수를 감시하는 또다른 시놉티콘을 발견할 수 있었다. 결론적으로 개인에 의한 블랙박스 감시는 파놉티콘 감시체제를 강화시키는 동시에 역감시도 수행하고 있었다. The dashboard camera is now an essential part of an automobile, which entails increasing surveillance by the cameras. dash-board cameras, or dash-cams, are useful in assessing responsibility in an accident and for reporting traffic violations. Dash-cam surveillance is different from panopticon surveillance in two aspects. First, dash-cam is a digitalized surveillance tool based on information technology. Secondly, the individual, who was being watched under the panopticon surveillance, is now the active surveillant. This study analyzes internet bulletin boards of an online dash-cam club and examines whom people watch, why they do it, what the surveillance behavior means to them, and what effects the new surveillance system has on the old system. The results are as follows. First, people watch various targets such as themselves, others, and insurance companies, and in doing so they establish their identity as active surveillants. Secondly, the online dash-cam club works as a kind of synopticon. In the club, a layperson can suggest a models in which to use the dash-cam, influencing public opinion. Thirdly, dashcams are connected to the surveillance assemblage through the acts of reporting, therefore strengthening the panopticon surveillance. Fourthly, as dash-cams are now a part of everyday life and reporting crimes/violations based on their video footage is common, people have become accustomed to the surveillance by dash-cams and the social acceptance of the surveillance has significantly increased. Lastly, insurance companies’ decisions regarding who is at fault in a car accident are often disputed by dash-cam videos, which can imply a synopticon situation where the majority exercise watch over the minority. In summary, while the dash cam surveillance over individuals has strengthened the panopticon surveillance system, it has simultaneously operated as the synopticon surveillance system.

<P>Owing to its high carrier mobility, conductivity, flexibility and optical transparency, graphene is a versatile material in micro- and macroelectronics. However, the low density of electrochemically active defects in graphene synthesized by chemical vapour deposition limits its application in biosensing. Here, we show that graphene doped with gold and combined with a gold mesh has improved electrochemical activity over bare graphene, sufficient to form a wearable patch for sweat-based diabetes monitoring and feedback therapy. The stretchable device features a serpentine bilayer of gold mesh and gold-doped graphene that forms an efficient electrochemical interface for the stable transfer of electrical signals. The patch consists of a heater, temperature, humidity, glucose and pH sensors and polymeric microneedles that can be thermally activated to deliver drugs transcutaneously. We show that the patch can be thermally actuated to deliver Metformin and reduce blood glucose levels in diabetic mice.</P>
