The purpose of this study was to evaluate the effect of age onthe ratio of pulp cavity/tooth width (P/T ratio) in healthycats. The dental radiographs of 32 cats (16 males and 16females) were generated with a digital dental X-ray unit withthe animals under general anesthesia. Standardizedmeasurement of the canine teeth was performed by drawinga line on the radiograph perpendicular to the cementoenameljunction (CEJ) of the tooth. There was an inverselyproportional correlation between chronological age and theP/T ratio. Moreover, a strong Pearson squared correlation(γ2 = 0.92) was identified by the curved regression model. Nosignificant differences in the P/T ratio based on gender orbreed were found. These results suggest that determinationof age by P/T ratio could be clinically useful for estimating the chronological age of cats.

박미정(Park Mijung),채경선(Chae Kyoungsun) 한국문화융합학회 2021 문화와 융합 Vol.43 No.11

본 연구에서는 초기성인의 대인관계 유능성에 영향을 미치는 내면화된 수치심, 공감, 인지적 정서조절을 검토하여 내면화된 수치심이 대인관계 유능성에 영향을 주는 과정을 공감 및 인지적 정서조절이 매개할 것으로 가정하여,이들 변인 간 관계를 구조적으로 알아보고자 한다. 본 연구는 초기 성인의 내면화된 수치심과 대인관계 유능성 간의 관계에서 공감과 인지적 정서조절의 매개효과를 분석하기 위해 2021년 2월 1일~10일까지 전국 성인남녀(20~40세) 558명을 대상으로 온라인 설문조사를 실시한 자료를 분석에 사용하였다. 분석방법은 SPSS 25.0와 AMOS 25.0 프로그램을 사용하여 빈도분석, 확인적 요인분석, 신뢰도 분석, 상관관계 분석, 수렴타당도, 판별타당도, 구조방적식 모형, 부트스트랩핑 방법을 실시하였다. 분석 결과는 다음과 같다. 첫째, 초기성인의 내면화된 수치심은 대인관계 유능성에 부적영향을 미쳤으며, 공감능력과 인지적 정서조절은 대인관계 유능성에 정적인 영향을 미쳤다. 둘째, 내면화된 수치심과 대인관계 유능성의 관계에서 공감능력은 완전매개효과가 있다. 셋째, 내면화된 수치심과 대인관계 유능성의 관계에서 인지적 정서조절은 완전매개효과가 있다. 넷째, 내면화된 수치심과 대인관계 유능성의 관계에서 공감능력과 인지적 정서조절의 순차적인 매개효과가 있다. 본 연구는 초기성인의 내면화된 수치심과 대인관계 유능성의 관계에서 매개변인으로 공감과 인지적 정서조절의매개역할을 검증함으로써 그 내부의 심리적 역동을 구체적으로 알아볼 수 있었다. 따라서 상담 및 심리치료 접근에서 내면화된 수치심을 가진 초기성인의 공감능력과 인지적 정서조절 능력을 높여 대인관계 유능성을 향상시킬 수있음을 시사한다. In this study, we want to examine the internalized shame, empathy, and cognitive emotional controlaffecting interpersonal ability of early adults, assuming that empathy and cognitive emotional controlwill mediate the process of internalized shame affecting interpersonal ability. In order to analyze the mediated effects of empathy and cognitive emotional control in therelationship between internalized shame and interpersonal ability of early adults, this study used databased on an online survey which was conducted on 558 adult men and women (20~40 years old)nationwide. The analysis methods were performed using SPSS 25.0 and AMOS 25.0 programs to analyzefrequency, confirmative factor analysis, reliability analysis, correlation analysis, convergence feasibility,discriminative feasibility, structural spinning model, and bootstrapping. The analysis results are as follows. First, internalized shame in early adults mis-affected interpersonal ability, and empathy and cognitiveemotional control had a static effect on interpersonal ability. Second, empathy in the relationship between internalized shame and interpersonal ability has acomplete mediating effect. Third, cognitive emotional control in the relationship between internalized shame and interpersonalability has a completely mediating effect. Fourth, there is a sequential mediating effect of empathy and cognitive emotional control in therelationship between internalized shame and interpersonal ability. This study was able to specifically identify the psychological dynamics within an early adult byverifying its role as a medium of empathy and cognitive emotional control as mediation variables inthe relationship between internalized shame and interpersonal ability. Therefore, we suggest thatinterpersonal ability can be improved by increasing empathy and cognitive emotional control of earlyadults with internalized shame through counseling and psychotherapy approaches.

The objective of this study is developing a classification scheme of the creative employment and analyzing trends of the creative employment in Korea. Many countries have pursued the creative economy to generate new jobs and tried to estimate the creative employment as a way to measure the creative economy. However, the definition of the creative employment is still ambiguous partly because it depends on the characteristics of diverse industries and the direction of economic policies that each country has. Therefore, we propose a classification scheme of the reative employment, which reflects the creative economy in Korea. Then, we examine how the creative employment changes in Korea. Our results show that the jobs requiring the highest level of creative skills increase stably and steadily over the years.

Measuring efficiency and ICT ecosystem impact: Hardware vs. software industry

Lee, Kyoungsun,Park, Yuri,Lee, Daeho Elsevier 2018 TelecommunicationsPolicy Vol.42 No.2

<P><B>Abstract</B></P> <P>The ICT industry is reshaping itself through convergence and coopetition across the ecosystem. In particular, many ICT companies have been trying to achieve both hardware and software capabilities to accelerate innovation. To understand the changes in the ICT industry, we empirically study the hardware and software industries using the ecosystem framework. We estimate the efficiency levels of the hardware and software industries in China, Japan, South Korea, and the United States (US) using stochastic frontier analysis and meta frontier analysis, and we examine the effects of the ICT ecosystem structure on efficiency levels using a Tobit regression. We find that the US, which is the global ICT leader, performs significantly better than other countries, with the biggest technology gap ratios in both hardware and software, and South Korea, which has the most hardware-centric industrial structure among the four countries, has the biggest efficiency gap between the hardware and software industries. Tobit results further reveal that a well-balanced ecosystem is important in achieving high efficiency in both hardware and software, and the effect is much higher in the software industry than in the hardware industry.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We study the hardware and software industries using the ecosystem framework. </LI> <LI> We estimate the efficiencies of the hardware and software industries using SFA. </LI> <LI> We compare the efficiency results using meta-frontier analysis. </LI> <LI> We examine the effects of the ICT ecosystem structure on efficiency levels. </LI> <LI> A well-balanced ecosystem is important in achieving high efficiency. </LI> </UL> </P>

Minjeong Jo,Mihyun Park,Kyoungsun Yun 한국간호과학회 2021 한국간호과학회 학술대회 Vol.2021 No.10

Aim(s): Effective communication between health care providers and patients and their families is one of the most important components of quality end-of-life care. However, nurses in South Korea are likely to be uncomfortable communicating advance care planning (ACP) due to the cultural taboo against talking about dying. The purpose of this study was to assess how an ACP training program affects Korean advanced practice nurse (APN) students’ ACP competencies. Method(s): Data collected from 34 APN students who participated in ACP training program conducted as part of graduate clinical practice course was analyzed. A training program was provided to APN students to improve their competencies in ACP conversations with patients. The program comprised three sessions: online lectures, face-to-face simulation, and discussions on ACP and ethical issues. After completing the program, the APN students were asked to describe their experiences with the training. A Wilcoxon matched pairs signed rank test was used to examine the changes in ACP knowledge, confidence in supporting patients’ advance directives, perceived nursing roles in end-of-life (EOL) treatment decisions, and perception of a good death before and after the training program. Result(s): APN students reported that their experience was positive and helpful. There was a statistically significant increase in participants’ ACP knowledge (p < .001), confidence in supporting patient’ advance directives (p < .018), and perception of the active role of nurse in patient EOL treatment decisions (p < .001) after the training. Conclusion(s): The results indicate the effects of training program on APN students’ competencies for EOL care. They also provide evidence about what contents and methods can be helpful in developing an EOL care training for APN students.

목적 본 연구에서는 한부모가구 청소년의 성별에 따른 음주정도와 음주 영향요인을 분석하였다. 방법 이를 위하여 제17차 청소년 건강행태온라인조사 중 연구목적에 적합한 764명을 대상으로 복합표본분석을 실시하였다. 한부모가구 청소년의 성별에 따른 인구사회학적 특성, 음주, 건강행동특성의 차이 및 음주에 따른 인구사회학적 특성, 건강행동특성의 차이는 Rao-Scott chi-square검정을 하였으며, 성별에 따른 음주 영향요인은 복합표본 Logistic regression을 실시하였다. 결과 한부모가구 여학생 330명, 남학생434명의 자료를 분석한 결과 한부모가구의 여학생 53.3%, 남학생 52.3%은 음주를 하고 있었다. 여학생은 음주 유무에 따라 흡연과 성경험에서, 남학생은 현재 흡연과 성경험, 스트레스 인지에서 유의한 차이가 있었다. 한부모가구 여학생의 음주 영향 요인은 현재 흡연으로 비흡연 여학생보다 5.89배 음주할 가능성이 있었다. 한부모가구 남학생의 음주영향요인은 주관적 체형인지, 현재 흡연, 성경험으로 보통 체형이라고 생각하는 경우보다 마르다고 생각하는 청소년이 0.75배, 현재 흡연하는 경우가 비흡연 경우보다 4.92배, 성경험이 있는 경우가 없는 경우보다 2.41배 음주할 가능성이 높았다. 결론 본 연구결과를 근거로 한부모가구 청소년의 성별에 따른 음주 영향 요인의 차이를 인식하고 성별에 맞는 차별화된 금주교육이 필요하며, 한부모가구 청소년이 건강하게 성장할 수 있도록 가정과 학교의 지속적인 관심이 필요하겠다. Objectives This study aimed to analyze the drinking level and influencing factors according to the gender of adolescents from single-parent households. Methods A total of 764 adolescents were selected and analyzed using the 17th Korean Youth Risk Behavior Survey. The Rao-Scott chi-square test was conducted to examine the differences in demographic characteristics, drinking, and health risk behavior according to gender of single parent household adolescents, and the differences in demographic and health risk behavior according to drinking. and complex sample logistic regression was performed for factors affecting drinking according to gender. Results As a result of analyzing the data of 330 female students and 434 male students from single-parent households, 53.3% of female students and 52.3% of male students in single-parent households were drinking. The factor influencing drinking among female students from single-parent households was current smoking, which was 5.89 times more likely to drink than non-smoker female students. The factors influencing drinking among male students from single-parent families were subjective body type, current smoking, and sexual experience. Male students who considered themselves to be thin drank 0.75 times more than male students who considered themselves normal, smokers 4.92 times more than non-smokers, and students with sexual experience 2.41 times more than non-sexual experience. Conclusions Based on the results of this study, differentiated education program according to the gender of adolescents from single-parent households is needed, and continuous attention from home and school is needed so that adolescents from single-parent households can grow up healthy.

재정정책의 불확실성이 생산, 소비, 투자 및 고용에 미치는 영향

김성훈(Kim, Seonghoon),박경선(Park, Kyoungsun) 전북대학교 산업경제연구소 2020 아태경상저널 Vol.12 No.1

이 연구는 미국의 정책 범주에 따른 불확실성 지수를 이용하여 재정정책의 불확실성이 생산, 소비, 투자 및 고용에 미치는 영향을 분석한다. 정부부채비율 변화와 재정정책 이외의 경제정책에서 비롯된 불확실성을 모형 내에서 통제한 후 재정정책 고유의 불확실성 충격을 식별하고 그에 대한 주요거시변수들의 반응을 추적한다. 주요 결과는 다음과 같다. 첫째, 재정정책의 불확실성 증가는 생산, 소비, 투자를 유의하게 감소시키고 실업률(고용률)을 유의하게 증가(감소)시키며 이러한 영향은 짧게는 3분기에서 길게는 3년에 걸쳐 나타난다. 둘째, 우리가 경험하는 생산, 소비, 투자, 고용의 변동성 가운데 대략 2~10%는 재정정책의 불확실성에서 비롯된다. 이는 기준금리나 물가상승률의 변화에서 비롯된 실질경제의 변동성에 비견된다. 이러한 결과는 예측가능하고 신뢰도 높은 재정정책은 그 자체로 경제에 도움이 될 수 있음을 의미한다. We examine the effects of fiscal policy uncertainty on output, consumption, investment, employment and unemployment. We take the U.S. categorical policy uncertainty indices along with federal debt to GDP ratio and identify orthogonal shocks to the fiscal policy within a Bayeisan VAR model. Our main findings are as follows: First, a shock to the fiscal policy uncertainty affects output, consumption, investment, employment and unemployment up to 3 years. Second, the fiscal policy uncertainty attributes as much as 2 to 10 percent of the total volatility of output, consumption, investment, and employment and unemployment. This is as high as either federal funds rate or inflation rate can attribute. By implication, untrustworthy fiscal policy can be harmful for economic performance.
