Background: Chemoradiotherapy is an important treatment modality for lung cancers. The aim of this study was to investigate alterations in, as well as the interrelationship between, lung function and quality of life of patients receiving chemoradiotherapy due to locally advanced non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) limited to the thorax. Materials and Methods: The study included patients receiving definitive chemoradiotherapy for lung carcinoma. The respiratory function of the patients was assessed by measuring forced expiratory volume in 1 s per unit (FEV1) and forced expiratory volume in 1s per unit of vital capacity (FEV1/VC) before, in the middle of and after treatment. During the study, EORTC QLQ C30 and LC13 questionnaires developed by the Committee of the European Organization for Research and Treatment of Cancer (EORTC) were employed to evaluate the quality of life on the same day as respiratory function tests (RFT). Findings: The study included 23 patients in total: 19 (82.6%) diagnosed with NSCLC and 4 (17.4%) with SCLC. The average percentage FEV1 was $55.6{\pm}21.8%$ in the pre-treatment period, $56.2{\pm}19.2%$ in the middle of treatment and $60.4{\pm}22%$ at the end of treatment. The improvement in functional scores, symptom scores and general health scores during treatment was not statistically significant (P= 0.568, P= 0.734, P= 0.680, P=0.757 respectively). Conclusions: Although this study showed an improvement in respiratory function and quality of life of patients during treatment with thoracic chemoradiotherapy, no statistically significant results were obtained. While evaluating the effectiveness of treatments for lung carcinoma, the effects of treatment on respiratory function and quality of life should be considered.

The education system is the communication field should be based on the characteristics of communication science and the function of manpower. However, the current education system at the level of college is insufficient and irrational to meet the requirements of the telecommunication field in our country. The main reasons are as follows: 1. Misunderstanding the characteristics of communication science. 2. Indiscretion of the categories of communication manpower due to lack of coordination between academic circles and communication industrial field. Telecommunication function could be performed only by combining the engineering and the suitable operational control. The communication engineering is similar to the electronic engineering, but the former should follow the miscellaneous international protocol and the domestic regulations, being only a means for the telecommunication function. In order to improve the education system of communiation, we aim to identify the principle of communication science, orthodoxy of the education, the categories of communication industrial field and manpower. The present system has been formed on the basis of ignoring the attributes of manpower and historical background of communication science. Therefore, this paper proposes to set up new departmental organizations for educating communication manpower as the following: In addition, this paper proposes a new curriculum model of the above twodept, and we believe that it well turn out more scientific, effective and reasonable education for the communication science. 1. Modification of the present formation, designated Electronic Communication Department. 2. New formation model: A. The best future model such as establishing ad independent telecommunication college which is composed of : Dept. of Radiocommunication Dept. of Telecommunication Enginnering Dept. of Communication Industrial management Dept. of Transmission Engineering Dept. of Telecommunication Law B. An immediately practicable proposal model instead of the existin Dept.. which is composed of the first two Dept. of the above five Dept. In addition, this paper proposes a new curriculum model of the above two dept. and we believe that it will turn out the education for the communication science to be more scientific, effective and reasonable.

Background: Many patients with chronic low back pain have reduced movement due to pain. For that reason, muscle strength weakens, which leads to pain again. The pain caused by such a vicious circle is not only caused by structural problems, but also by physical function, activity disorder, or psychological depression due to biopsychosocial approaches and pain neuroscience education was applied as an intervention to find out its effect. Therefore, this study was experimented with to find out the effects of pain neuroscience education on pain, physical function, activity disorder, and depression in patients with chronic low back pain. Design: Randomized control trial Method: The study subjects were 39 patients with chronic low back pain, and the study subjects were randomized through computers to the experimental group applying pain neuroscience education and the control group applying only general physical therapy and myofascial release techniques, and the experiment was conducted for 4 weeks. Pressure Pain Threshold , Schober test, Korean Roland-Morris Disability Questionnaire, Korean Oswestry Disability Index, and Korean Depression Screening Assessment were measured. Results: As a result of the study, there was no significant difference in pain neuroscience education compared to the group that applied only general physical therapy and myofascial release techniques in both lumbar pressure pain thresholds, Schober test, Korean Roland-Morris disability questionnaire, and Korean Oswestry disability questionnaire. However, the Korean Depression Screening Assessment which is the result of measuring depression, showed significant results(p<0.05). Conclusion: Therefore, it is believed that it can be a way to mediate the psychological part through pain neuroscience education for patients with chronic low back pain in the future.

Purpose: This study examined the effects of a positioning education program through the brochure or oral explanations for the parents of premature infants with a brain lesion and investigated the satisfaction level of physical therapy of parents of premature infants with a brain lesion. Methods: Forty parents of premature infants with a brain lesion participated in this study. The recruited premature infants were randomized into groups A (n=20) and B (n=20) for the purpose of the positioning education method through brochure or oral explanations. The level of satisfaction and recognition for the positioning education program was investigated by the parents of 12 month old infants. The gross motor function, measure-88, was examined at three months, six months, nine months, and twelve months of the corrected age. Results: No significant differences in the recognition of the position education program, level of satisfaction of the environment, and the attitude of the therapist were noted (p>0.05). Significantly high levels of satisfaction with the program of group B given the brochure were noted. The gross motor function measure-88 was also similar in both groups (p<0.05). Conclusion: This study suggests that the parents were satisfied with the positioning education program of the brochure. The differences in educational methods did not affect the development of premature infants.

The purpose of this study was to evaluate effects of a nutrition education focused on Food Exchange System for the higher grades elementary children. Nutrition education lessons (40 min/lesson, 4 times), '5 major nutrients and functions', '6 food groups', 'daily needed energy and food exchange units', 'good choice of snacks and balanced exercise' were provided to elementary students (5th grade students). This research was based on the data from two groups of elementary school children in the 'education' group (n = 31) and 'non-education' group (n = 31). We assessed the changes in dietary attitude, food habit and nutrition knowledge using questionnaire and nutrient intake using 24hr recall method by nutrition education using the developed pamphlet. After education, there was a significant difference in the dietary attitude score only in attitude of 'balanced meal' (p < 0.001) in the education group compared to the non-education group. In food habit, there were significant positive changes in the type of breakfast and in the priority of choosing snack in the educated group. In nutrition knowledge, there were significant increases in scores of 'function of carbohydrate' (p < 0.05), 'function of fat' (p < 0.01), 'function of vitamin' (p < 0.01), 'foods of carbohydrate' (p < 0.01), and 'foods of vitamin' (p < 0.01) in the educated group. After education, carbohydrate: protein: fat (CPF) ratio was significantly different between the two groups (education group, 59 : 16 : 26 vs. non-education group, 63 : 15 : 23). In evaluation of nutrient intake by Dietary Reference Intakes for Koreans (KDRIs), there were significant positive effects in energy (p < 0.05), thiamin (p < 0.05), riboflavin (p < 0.05), vitamin C (p < 0.05), phosphorus (p < 0.01), Fe (p < 0.01) and zinc (p < 0.01) in the education group compared to the non-education group. In conclusion, the developed 4 times' nutritional education pamphlet focused on individual daily energy requirements and food exchange units using food exchange system for higher grades' elementary student may positively change nutrition knowledge and dietary intakes.

Objective: Adipocyte differentiation is regulated by a variety of functional genes and noncoding RNAs. However, the role of miRNAs in lipid deposition of goat white adipose tissue is still unclear. Therefore, this study revealed the miRNA expression profile in goat subcutaneous adipocytes by sRNA-seq. Methods: The miRNA expressed in goat subcutaneous preadipocytes and the mature adipocytes were sequenced by sRNA-seq. The differentially expressed miRNAs (DEm) were screened and gene ontology (GO) and Kyoto encyclopedia for genes and genomes (KEGG) analyses were performed. Gain-of-function and loss-of-function combined with oil red O staining, Bodipy staining, and quantitative reverse-transcription polymerase chain reaction (qPCR) were utilized to determine the effect of miR-133a-3p on adipocyte differentiation. Results: A total of 218 DEm were screened out. The target genes of these DEm were significantly enriched in GO items such as biological regulation and in KEGG terms such as FAK signaling pathway and MAPK signaling pathway. qPCR verified that the expression trend of miRNA was consistent with miRNA-seq. The gain-of-function or loss-of-function of miR-133a-3p showed that it promoted or inhibited the accumulation of lipid droplets, and CCAAT enhancer binding protein α (C/EBPα) and C/EBPβ were extremely significantly up-regulated or down-regulated respectively (p<0.01), the loss-of-function also led to a significant down-regulation of peroxisome proliferator activated receptor gamma (PPARγ) (p<0.01). Conclusion: This study successfully identified miRNAs expression patterns in goat subcutaneous adipocytes, and functional identification indicates that miR-133a-3p is a positive regulator of the differentiation process of goat subcutaneous adipocytes. Our results lay the foundation for the molecular mechanism of lipid deposition in meat-source goats from the perspective of miRNA.

The purpose of this study was to evaluate the effect of the nutrition education on preschool children's nutrition knowledge and behaviors. The study subjects were preschool children attending J kindergarten located in Wonju. Each of the control group and the education group consisted of 49 children and the education group was exposed to nutrition education while the control group did not. The nutrition education intervention lasted 9 weeks weekly basis. The t-test for the homogeneity of each group showed no meaningful difference at the beginning point of nutrition education. After nutrition education a test of nutrition knowledge using picture-questionnaire was carried out by the researcher for the subjects of education group and control group and the caretakers of the education group were offered self-administered questionnaire on the changes in children's dietary behaviors. The results of the study were as follows: 1. Nutrition education intervention showed a meaningful difference in children's understanding nutrition; the kinds and function of food, the relationship between food and body, the function of nutrients and enhanced their idea on hygiene compared to the control group (p < p.005). 2. However, nutrition education intervention made no statistically meaningful difference in children's dietary behaviors such as having breakfast, keeping balanced diet, washing hands before meals, saying "thanks" before and after meals, cleaning the table after meals, brushing teeth after meals and so on. Therefore, we found that it is hard to expect children to correct their dietary behaviors in such a short period of 9 weeks and nutrition education for preschool children should be offered to caretakers at the same time.

Hardy and Littlewood found a relation between the smoothness of the radial limit of an analytic function on the unit disk D ⊂ ℂ and the growth of its derivative. It is reasonable to expect an analytic function to be smooth on the boundary if its derivative grows slowly, and conversely. Gehring and Martio showed this principle for uniform domains in ℝ². Astala and Gehring proved quasiconformal analogue of this principle for uniform domains in ℝⁿ. We consider α-quasihyperbolic metric, k^α_D and we extend it to proper domains in ℝⁿ.
