권인수,이주현,이재진 한국통신학회 2001 韓國通信學會論文誌 Vol.26 No.10

본 논문에서는 고밀도 광 기록 시스템에 적용이 가능한 코드율이 8/15이고, (d, $textsc{k}$)=(2, 15)인 새로운 변조 코드 체계에 대한 변조 코딩 방법을 VHDL로 구현하였다. 인코딩 방법은 크게 세 가지로 구분되어 진다. 먼저 입력 데이터를 복수개의 바이트 단위로 묶어서 블록을 정의하고, 이 블록의 입력 데이터를 변환 테이블을 이용해서 채널 데이터로 변환한 후, 머징 비트(merging bits)를 첨가하여 데이터를 전송한다. 위와 같은 코딩 방법을 적용하여 새롭게 개발한 변조 코드에 대해 모의 실험을 통한 성능을 분석한 후 VHDL로 구현하여 검증하였다.

권인수,Nurul Fatihah Talib,JunShu Zhu,양형인,김경수 한국운동영양학회 2023 Physical Activity and Nutrition (Phys Act Nutr) Vol.27 No.2

[Purpose] Aging is closely associated with chronic metabolic diseases, such as obesity, which lead to increased adiposity, skeletal muscle wasting, and imbalanced cellular energy metabolism. However, transcriptional profiles representing energy imbalances in aging-induced obesity are not fully understood. Thus, this study aimed to investigate the candidate genes predominantly regulated in aging-related obesity in spontaneously aged mice. [Methods] Male C57BL/6J mice were divided into three age groups according to age: 2- (young), 12- (middle-aged), and 24- (old) months. Body weight and body composition parameters were measured in all mice. Gonadal white adipose tissue (gWAT), brown adipose tissue (BAT), and skeletal muscle (SM) were dissected and weighed. The target tissues were assessed using biochemical and histological assays. [Results] Aging-induced obesity increased adipose mass and decreased SM weight through processes of adipocyte hypertrophy; however, recruitment of modulating adipogenesis-inducing transcription factors did not occur. Among adipokines, leptin level was greatly increased in the gWAT during aging. Interestingly, the β2-adrenergic receptor had a higher affinity than the β3-adrenergic receptor in aging-induced obesity. For the thermogenic regulation through β-adrenergic receptors (β-ARs), a declined uncoupling protein-1 (UCP- 1) in the BAT was relevant to aging-induced obesity. [Conclusion] Aging-induced obesity increases leptin levels in adipocytes and decreases UCP-1 in BAT through β-ARs, according to transcriptional gene profiling. WAT browning increases energy expenditure due to exercise training adaptations. Further research is needed to discover more effective methods, such as exercise, against aging-induced obesity.

  본 연구는 인수합병과정과 이후에 나타나는 통합을 위한 경영관리행위(통합관리행위)가 피합병구성원들의 조직몰입과 조직시민행동에 미치는 영향을 살펴보는데 그 목적이 있다. 통합을 위한 경영관리로서 고용안정성, 임파워먼트, 합병의 투명성과 공정성 등 네 변수를 설정하여 독립변수, 조직시민행동을 종속변수, 그리고 독립변수와 종속변수 사이에 조직몰입의 매개변수로 설정하여 네 가지 통합관리 변수가 조직시민행동에 미치는 직접적인 효과와 조직몰입을 통하여 미치는 간접적인 효과를 구체적으로 살펴보고 있다.<BR>  분석에는 인수합병을 경험한 두 개 시중 은행의 피합병기업 직원을 대상으로 설문조사를 실시하여 얻은 245개의 표본 자료를 사용하였으며, 그 결과는 다음과 같다. 첫째, 고용안정성은 조직시민행동에 유의한 정의 영향을 미치는 것으로 나타났다. 구체적으로는 고용안정성이 높을수록 조직시민행동의 하위차원인 이타성, 예의성, 성실성, 시민정신 등이 높은 것으로 나타났다. 하지만 예측과 달리 임파워먼트는 스포츠맨십과 성실성에 유의한 부(-)의 영향을 미치는 것으로 나타났고, 합병의 공정성과 투명성은 유익하지 않은 것으로 나타났다. 그리고 조직몰입이 고용안정성과 조직시민행동의 관계를 매개하는 것으로 나타났다.   This study examines effects of employees" perception on integration practices during and after merger and acquisition(M&A) on their organizational citizenship behavior (OCE). The study also aims to analyze mechanisms by which the integration practices affect employees" OCB directly and/or indirectly through the mediating effect of organizational commitment. Despite the importance of the integration practices, few studies empirically test whether and how the integration action affect employees" behavior, particularly of a merged firm. This study is to fill the gap by examining effects of the integration practices on employees" OCB. This study selects four practices as the integration practices, including M&A transparency, procedural justice, job security, and empowerment.<BR>  We formulate and test a research model. The model includes independent variables, i.e. M&A transparency, procedural justice, job security, and empowerment, a mediating one, organizational commitment, and a dependent variable, employees" OCB. In order to test the model, hierarchical regression tests were conducted for the data obtained from 245 employees.<BR>  The result of the empirical analysis shows that job security have a significant and positive effect on OCB, and four OCB"s sub-constructs variables including altruism, courtesy, conscientiousness, civic virtue. As not expected, empowerment have a significant and negative effect onsportsmanship,conscientiousness, but have no significant effect on OCB. In addition, this study presents job security has an impact on OCB indirectly through the mediating effect of organizational commitment, and on the four OCB"s sub-constructs variables indirectly.

Endurance exercise training reinforces muscular strength with improvements in mitochondrial oxidative capacity, lysosome reformation, and myogenic differentiation against doxorubicin-induced skeletal muscle wasting in mice

권인수 한국운동영양학회 2023 Physical Activity and Nutrition (Phys Act Nutr) Vol.27 No.1

[Purpose] Doxorubicin (DOX) is a chemotherapeutic medication broadly used to treat diverse cancers. However, chronic DOX chemotherapy can cause myotoxicity and muscle atrophy. Endurance exercise (EXE) is used to prevent negative muscle excitation. Based on emerging evidence, this study investigated the challenges that occur in skeletal muscle quantity, quality, and metabolic determinants through autophagy, myogenic regulatory factors (MRF), antioxidant enzymes, and both the AMPK and AKT/mTOR pathways. [Methods] Male C57BL/6J adult mice were divided into four groups after one week of acclimation: sedentary (SED) plus saline (SAL)-receiving (SED-SAL), EXE plus SAL-receiving (EXE-SAL), SED plus DOX-receiving (SED-DOX), and EXE plus DOX-receiving (EXE- DOX) groups. All mice were intraperitoneally inoculated with either SAL or DOX (5 mg/kg, every 2 weeks) for 8 weeks, while a treadmill running EXE was performed. Body weight, muscle weight, and muscle strength were measured, and the red portions of the gastrocnemius muscle were excised for biochemical analysis. [Results] Chronic DOX administration deteriorated body composition by decreasing body and absolute muscle weights, whereas EXE reinforced a grip strength per body weight. Although DOX inhibited BECN1 expression, EXE enhanced CS, LC3-I, LC3- II, and LAMP levels. Moreover, DOX did not interrupt MRF functions, but EXE improved MYOD without altering SOD1 or SOD2 expression. However, neither the AMPK nor the AKT/mTOR signaling pathways were associated with either DOX-receiving or EXE training. [Conclusion] DOX chemotherapy-induced muscle wasting is associated with autophagy dysregulation. However, long-term aerobic EXE training enhances muscular strength with an increase in mitochondrial oxidative capacity, lysosome formation, and myogenic differentiation.

아동간호학에서의 아버지 자녀양육에 대한 연구 경향과 전망

권인수 한국아동간호학회 2013 Child Health Nursing Research Vol.19 No.2

아버지의 자녀양육에 대한 사회적, 개인적 필요성이 증대되고, 아동의 발달과 건강에 대한 아버지 양육참여의 긍정적 영향력이 밝혀지면서 여러 학문 분야에서 아버지의 자녀양육에 대한 관심이 높아졌다. 아동간호학은 아동의 발달과정과 건강 및 돌보기에 대한 지식과 기술을 다루는 학문으로 대상자에게 접근이 용이하기 때문에 아동 양육과 관련된 여러 학문 분야 중에서 부모역할을 개발할 수 있는 가장 적절한 전문 분야로 볼 수 있다. 이에 아버지의 자녀양육에 대해 인접 학문분야와 아동간호학 분야의 선행연구들을 고찰하고 아동간호학에서의 아버지 자녀양육에 관한 추 후 연구를 전망해 보고자 하였다. 아동간호학에서 자녀양육에 대한 연구는 거의 어머니를 대상으로 이루어졌고 아버지 대상연구는 극소수에 불과하므로 아동간호학의 아버지 자녀양육에 대한 학문적 요구를 볼 때 관련 연구가 활성화되고 이를 기반으로 간호실무도 활성화되어야 할 것이다. 연구의 내용에 있어서는 인접 학문분야에서는 다루기 어려운 주제로서 아버지의 자녀양육이 아동의 건강 및 건강습관에 미치는 영향을 심도 있게 연구할 필요가 있고, 양육자로서 아버지를 이해하고 지지하기 위해 아버지가 자녀양육과정에서 경험하는 감정, 어려움과 요구 등의 반응을 탐색할 필요가 있다. 연구방법에 있어서는 양육수행의 정확성을 파악할 수 있도록 자가보고 보다는 관찰법과 같은 객관적 방법에 의한 측정이 필요하고, 아버지의 자녀양육을 향상시키기 위한 중재개발 연구를 수행할 필요가 있다. 이러한 연구를 통해 아버지 자녀양육 분야에서 아동간호학의 차별화된 지식을 개발하는데 기여하고, 아동간호학 실무발전에 기여할 수 있을 것이다.

Purpose: This study was done to assess the home nursing and quality of life of parents caring for preschool children with atopic dermatitis and to identify the factors which influence quality of life. Methods: Participants in the study were 149 parents of preschool children with atopic dermatitis attending a kindergarten and a nursery school in S city. Parent completed a set of questionnaires (assessing demographic factors, home nursing, quality of life). Descriptive analysis, t-test, ANOVA and multiple regression were used to analyze the data. Results: The mean score for home nursing was 3.06±0.38 and for quality of life, 4.18±0.74. The lowest scored question in the 13 question on quality of life was that of frustration related to itching sensation. Significant factors that affect quality of life were severity and home care. These variables explained 21% of variance in quality of life (F=21.17, p<.001). Conclusion: The results indicate that severity of childhood atopic dermatitis and home nursing impact on the quality of life of parents. Using the above findings, health professionals who work with children with atopic dermatitis and their parents need to develop specific nursing interventions that will promote health of children with atopic dermatitis and quality of life in their parents.

산욕기 산모의 산후적응 척도개발을 위한 일연구

권인수 中央醫學社 1991 中央醫學 Vol.56 No.2

The postpartum mother experiences many normal but important & potentially dangerous physiologic & psychological changes. Physiologic changes can be life-threatening, and psychological & familial adjustments can be threaten mental health or other family stabily and the neonate's long-term physical & psychological well-being. Therefore, the concept of postpartum adaptation must be a central theme in health related research, particularly nursing. But postpartum adaptation has been described in a variety of ways & measured differently from study to study. So there is a lack of conceptual agreement on what is postpartum adaptation. The purpose of this study was to develop a scale to measure postpartum adaptation & to test its reliability & validity & select the items for the final scale. The data was collected from June 5 to 14, 1990. The subject of this study were 78 healthy mothers in puerperium period and collected data were analyzed using the SPSS PC+ Package. The process & results of the study may be summarized as follows. 1. In developing this instrument, the researcher first established a conceptual framework based on the results of previous research & exporatory survey. The scale for this instrument consisted of 74 items, covering 4 factors. 2. The content validity was obtained through meetings for discussion by two judge ment groups. As the result, 28 items were deleted from the scale. 3. The reliability of this scale was tested by Cronbach's alpha, the coefficient was.9524. 4. The construct validity was tested by known group technique. The degree of postpartum adaptation for cesarean sectian mothers was significaantly lower than for vaginal delivery mothers. 5. As a conclusion, this developed scale is a self-reporting, 31 item Likert scale, covering 4 factors; physical status and function (7 items), self-identity (9 items), family relationship (7 items), baby care activity (8 items). 6. Further studies to retest the reliability & validity are strongly recommended.
