  • 역전층 현상은 주로 맑은 날 야간 복사냉각에 의해 종종 나타나는 현상으로 사계절 모두 빈번히 존재한다. 하지만 역전층의 발달 정도와 강도 등은 그 날의 일기상태에 의해 크게 좌우되며, 또한 그 지역의 기후 및 지리적인 환경도 중요한 역할을 한다. 본 연구 대상지역인 울산지역은 산업화에 따른 고도성장을 이룬 도시 중 하나로 우리나라 최대공업도시로 잘 알려져 있다. 이와 같은 도시의 야간 역전층 생성 및 발달과정에 있어서 토시 내 인공열의 효과 역시 중요한 요인으로 작용 할 수 있다. (중략)

  • 전자광학산업을 둘러싼 성장환경 여건은 모바일화, 디지털화, 융합화 등으로 빠르게 변화되고 있다. 이러한 변화는 광학기술, 반도체, 디스플레이 등 핵심부품은 물론 시스템의 수요 증가로 연결돼, 향후 이들 시장이 폭발적으로 늘어날 것이다. 따라서 이에 대응한 기술개발이 필요하다. 또한 친환경관련 기술이나 에너지관련 기술이 급속히 발달되고 있다. 전통산업에도 IT기반의 융합화가 계속적으로 진전됨에 따라, 이 분야의 획기적인 연구개발 투자가 필요하다. 특히 광학분야는 의료기기를 비롯한 다양한 분야에서 융합되어 발달될 것이므로 시장 사이즈가 큰 것부터 서둘러야 할 것이다.

  • Myostatin is a transforming growth and differentiation factor-${\beta}$ family member that acts as a negative regulator of muscle growth. Previously, mutations in the myostatin gene were known to be related to double muscling phenotypes in cattle. Because myostatin gene is highly related to muscle mass, also meat quality, in cattle, we sequenced whole myostatin mRNA and investigated the SNPs (Single Nucleotide Polymorphisms) in Korean cattle (Hanwoo). The results indicated that Hanwoo had an SNP in nt2385 and this mutation can be a useful marker with further verifications. We also investigated expression patterns of the myostatin gene from various muscle tissues and organs. Northern blotting results indicated that myostatin expression was restricted in muscles with variable expression levels. The results presented here can be used as a valuable information for meat quality related traits and muscle mass in cattle.

  • Granulosa cells, which surround the oocyte within the ovarian follicle, play an essential role in creating conditions required for the development of oocytes and follicles. The solute carrier family (SLC) is comprised of influx transporters of steroidal hormones, various drugs, and several other substrates. The differential expression of selected DEGs was confirmed using in situ hybridization analysis. SLC23A3 and SLC39A10 were highly expressed in the ovary. The SLC39A10 gene was expressed in the primordial follicle stage, but SLC23A3 was expressed in the growing follicle stage. Contrastingly, the expression of SLC23A3 was increased in granulosa cells at the growing follicle stage. The differential expressions of SLC23A3 and SLC39A10 between the primordial and primary follicles were additionally confirmed by using follicle isolations. The gene expression profile from the present study may provide insight for future studies on the mechanism(s) involved in primordial-primary follicular transition and suggestions to promote follicular development in ovarian dysfunction.

  • The purpose of this study is to explore undergraduate students' professional growth experiences as a novice counselor through reflective journal writing. Study participants were six students who completed the counseling skills course. The analysis was done on their weekly reflective journals using Colaizzi's phenomenological qualitative method. As a result, 11 sub-categories and 3 categories were emerged: increasing recognition and knowledge regarding counseling, being troubled and frustrated due to one's inexperiences of counseling, trying to overcome frustration toward professional counselors. This study revealed counseling major undergraduate students' professional development experiences and can be utilized in counseling training program development in the future.

  • Problem-Based Learning (PBL) is a student-centered pedagogy that integrates nursing knowledge, skills, and attitudes into clinical nursing practice. This pilot aims to apply a PBL module on preschoolers' growth and development in the nursing curriculum. This quantitative study was performed to develop a PBL module following Dick and Carye's program development process (planning, development, application, and evaluation phases), and to evaluate its effects using structured questionnaires among sophomore nursing students. These students formed teams of four or five people each and spent 40 minutes participating in the PBL module. Data were analyzed using descriptive statistics, t-tests, and content analysis. Metacognition level increased significantly. There was no significant difference in team efficacy between pre-test and post-test. Post-test learning satisfaction was high. Students reported obtaining knowledge and problem-solving ability with respect to preschoolers' growth and development and were satisfied with teamwork. This finding offers fundamental knowledge concerning the application of a PBL module in nursing curricula.

  • Despite a recent increased nation's attention given to improving end-life care, we professionals need to be more critical and reflective on our realities surrounding hospice palliative care. The aim of this paper is to suggest that palliative care models can be used for patients/families in the last phase of life and examine whether they are appropriate for caring them in congruence with philosophy of hospice. The hospice experience model (HEM) of Eagan & Labyak and the developmental model of Byock are introduced and examined for their congruence with philosophy of hospice in applying to clinical practice. The HEM as a patient/family value-directed end of life care model emphasizes three principles; unique experience of patient/family, interactions/relationships among multiple dimensions of personhood and between family, and personal growth and development in the face of suffering through a life-completion. The developmental model stipulates dying as the last stage of living, a stage of life cycle in which patients/family may have growth through life-completion in multidimensional relationships of personhood. The model includes the developmental landmarks and tasks for life-completion as the framework to guide a means of professionals' to recognize their opportunity to grow. The landmarks and tasks include worldly and social affair, individual relationships, intrapersonal, and transcendent dimension. The models could work as appropriate palliative care models for patients/families in the last stage of living. The professionals need to be encouraged to apply the models to end of life care setting.

  • Environmental condition can induce changes in early life-history traits in order to maximise the ecological fitness. Here I investigated how temperature change and variation in human aquatic activity/behaviour affect early life-history consequences in fish using a dynamic-state-dependent model. In this study, I developed a general fish's life-history model including three life-history states depend-ing on foraging activity, such as body mass, mass of reproductive tissue (i.e., gonadal development) and accumulated stress (i.e., cellular or physiological damage). I assumed the level of foraging activity maximises reproductive success-ultimately, fitness. The model predicts that growth rate, development of reproductive tissues and damage accumulation are greater in higher temperature whereas higher human aquatic activity rapidly reduced the growth rate and development of reproductive tissue and increased damage accumulation. While higher foraging activity in higher temperature is less affected by human aquatic activity, the foraging activity in lower temperature rapidly declined with human aquatic activity. Moreover, lower survival rate in higher temperature or human aquatic activity was independent on mortality rate due to human aquatic activity or mortality rate when foraging activity, respectively. However, the survival rate in lower temperature or human aquatic activity was dependent on these mortality rates. My findings suggest that including of early life-history traits in relation to climate-change and human aquatic activity on the analysis may improve conservation plan and health assessment in aquatic ecosystem.

  • 인간은 출생부터 필연적으로 부모와 관계 속에서 다양한 경험을 통해 성장하고 발전하게 된다. 자녀가 세상에 태어나면서 부모와 언어적, 비언어적 의사소통을 통해 다양한 관계를 경험하면서 성장하고 발전하면서, 본인의 가치관 정립과 대인관계 형성을 위한 기초가 된다. 부모-자녀 간 원활하지 못한 의사소통이 자녀에게 정신건강 문제와 이탈, 비행과 범죄로 연결된다는 것을 많은 연구 사례가 볼 수가 있다. 이러한 선행연구를 살펴보면서 부모와 자녀 간의 원활한 개방적 의사소통이 자녀의 성장과 대인관계 형성을 하는 데 중요한 역할을 하지만, 원활하지 못한 의사소통이 이루어지면은 발전과 성장에 많은 문제를 가지고 청소년기를 보내고, 성인이 되어서도 건강하지 못 할 수가 있다. 본 연구의 목적은 중기 청소년의 성장 과정에서 자기 통제력 향상에 부모와 자녀의 개방적 의사소통이 원활할 때 중기 청소년의 발달과 성장에 영향을 줄 수 있는 자기 통제력에 대해 부모-자녀 간 개방적 의사소통의 매개 역할을 하는지를 검증하는 데 있다. 부모-자녀 간 메시지 전달이 감정교류 및 정보전달 등을 모두 포함하는 상호작용을 통해 성장과 발전을 할 수 있다는 것을 알 수 있다. 중기 청소년의 부모-자녀 간 원활한 의사소통에 영향을 미칠 수 있는 자기 통제력을 종속변수로 설정하여 본 연구를 검증하기 위해 진행하였다.
