This research is to analyze the mediating effect of product innovation between work-life balance (work-family balance, work-leisure balance and work-development balance) and corporate performance in venture SMEs. We test four hypothesis. First, we test the hypothesis that work-life balance has a positive effect on product innovation. Second, we test the hypothesis that product innovation has a positive effect on corporate performance. Third, we test the hypothesis that work-life balance has a positive effect on corporate performance. Fourth, we test a positive mediating role of product innovation between work-life balance and corporate performance. For this research, we administered the questionnaire surveys, and got the 162 effective data of korean venture SMEs. We use CFA and SEM analysis of research model by AMOS 18.0. As a result, we can find the four meaningful results. First, work-life balance, especially only work-development balance, has a positive effect on product innovation. Second, product innovation has a positive effect on corporate performance. Third, the relationships between work-life balance (work-family balance, work-leisure balance and work-development balance) and corporate performance are no significant after the mediating variable (product innovation) is added. Fourth, product innovation has a positive mediating effect between work-life balance, especially only work-development balance, and corporate performance. Although this research has some limitations of generalization because of the limited size of samples, we has meaningful information related to the venture companies in the academic and business field. Additionally, the Multiple Indicator Multiple Cause(MIMIC) model is recommended in the future research.

In previous studies, the dynamic exercise equipment just focused on the trunk stabilization exercise. However, our study is targeted at evaluation for the impact on the postural balance of those researches. Twelve male and twelve female subjects were volunteered for the balance training using this system. They had no medical history of backpain for the past six months. Trunk Stability and postural balance training was performed for 15 minutes a day, three times a week duing four weeks. To evaluate characterization of the postural balance using Balance System SD, Evaluation consist of the postural stability test and the postural limit test. As a result, this training with 3D dynamic exercise equipment help subjects improve the postural balance. These results are expected for using basic materials to the elderly with a high risk of falling and trained athletes needed to be a postural control.

This paper aims to understand the meaning of balanced development among regional economies and its importance in the s0-called knowledge-based economy. It is shown that the balanced allocation of human capital is necessary to achieve the efficient allocation of physical capital among regional economies, which makes the equality of marginal product of capital. And a simulation experiment is conducted to calculate the cost of unbalanced growth. It is shown that balanced growth among regional economies may increase the growth rate of whole national economy while unbalanced growth among them reduce it. The policy implication is that for an any economy to grow at a higher rate, the efficient allocation of physical and human capital both are necessary to have the balanced growth of regional economies in knowledge-based economy.

본고(本稿)는 금융시장(金融市場)의 규모(規模)와 금융산업구조(金融産業構造)와의 관계에 대한 몇가지의 가설(假說)을 미국(美國), 영국(英國), 독일(獨逸), 프랑스, 캐나다, 이탈리아, 스웨덴, 벨기에, 네덜란드, 스페인 등 11개 OECD국가와 한국(韓國)의 시계열자료(時系列資料) 및 동(同) 자료(資料)의 크로스섹션결합자료(結合資料)를 이용하여 검증하였다. 검증결과에 의하면, (1) 각국의 직(直) 간접금융비중(間接金融比重)은 전체 금융시장규모에 의해 유의하게 영향을 받고 있으며, (2) 직(直) 간접금융(間接金融)은 시장규모(市場規模)의 확대(擴大)에 따라 어느 하나가 압도함이 없이 일정한 균형비율로 수렴해 나가는 것으로 관찰되고 있어 세계금융산업(世界金融産業)은 일반적으로 전업균형(專業均衡)보다는 전업(專業) 및 겸업(兼業)의 혼합균형(混合均衡)으로 이행해 나갈 것으로 기대되며, (3) 최근 진행되고 있는 금융(金融)의 세계화(世界化) 및 개방화(開放化) 추세(趨勢)는 궁극적으로 각국 금융산업조직(金融産業組織)의 동질화(同質化)를 촉진시킬 것으로 나타나고 있고, (4) 금융시장규모(金融市場規模)의 확대(擴大)에 따른 혼합균형(混合均衡)으로의 이행과정에서는, 겸업주의(兼業主義) 은행제도(銀行制度)는 금융시장의 규모가 상대적으로 작은 경제에서, 역으로 전업주의(專業主義) 은행제도(銀行制度)는 금융시장의 규모가 상대적으로 큰 경제에서 주로 형성되는 경향이 있는 것으로 관찰되었다. 부수적으로는, 전업주의(專業主義) 금융제도(金融制度)에 비해 금융업무(金融業務)의 자유(自由)를 보다 더 허용하는 겸업주의(兼業主義) 금융제도(金融制度)가 균형금융구조(均衡金融構造)로의 이행(移行)을 촉진시키고 있다는 점도 발견되었다. 이상의 검증결과는, 금융산업(金融産業) 및 제도(制度)는 이를 받치는 전체 금융(金融)의 규모성장(規模成長)에 따라 적절한 균형구조(均衡構造)를 찾아가는 것이기 때문에 전체 금융의 성장과정 및 속도에 부응하지 못하는 인위적인 금융개편정책(金融改編政策)은 바람직하지 못하다는 시사를 주고 있다.

Vessels or aircraft should be loaded with containers or cargo to maintain weight balance in order to be stable when navigating the route. The container loading algorithm is known as the NP problem and several heuristic methods have been studied. Containers can be characterized by the uniform volume and weight, which makes it easier to find an optimal loading method. In this paper, we propose an algorithm for weight balance when the volume and weight of an object are uniform. It is assumed that the loading space has a special structure of m * n mesh (where m and n are both odd). In this case, we designed a greedy algorithm and proved that the algorithm is optimal in that it can always find a loading position that maintains a weight balance regardless of the number of objects. Our algorithm can be used in many engineering problems, such as loading algorithms and load balancing problems.

The purpose of this study is to describe the effects of temporomandibular joint balancing therapy on a patient with a spinal accessory neuropathy. A patient reported sternocleidomastoid muscle and trapezius muscle weakness after self-massage. The patient was instructed to wear the Accurate Balancing Appliance (ABA) for at least 8 hours per day and maintain an upright posture. The patient received cervical spine manipulation on day 2, 4, and 6. The patient's progress was tracked based on the angle at which the head turned to the right from the midline when she lifted her head while lying down, as well as the muscle strength and pain in the right trapezius muscle. The patient recovered spontaneously after 7 days. The ABA and cervical spine manipulation assisted the patient in reducing fatigue and discomfort during daily activities.

Purpose: Screening of preschool-age children for nutrition programs to improve dietary intake and behaviors requires cost-effective and easily administered validated assessment tools. The purpose of this study was to develop a parent/caregiver-administered instrument for measuring diet quality and behaviors of preschoolers as a nutrition quotient for preschoolers (NQ-P). Methods: Development of NQ-P was carried out in three steps: item generation, item reduction, and validation. The 24-h dietary record was selected as the gold standard reference tool. The 38 items of the NQ-P checklist were derived from a systematic literature review, expert in-depth interviews, statistical analysis of the fifth Korean National Health and Nutrition Examination Survey data, and national nutrition policies and recommendations. Self-administered questionnaires were delivered to parents who recorded 24-h dietary intakes of 100 responders aged 3~5 yr. Pearson's correlation was used to measure the level of agreement between questionnaires. Item reduction was performed, and 20 items were selected based on survey results, expert reviews, and priorities of national nutrition policy and recommendations. The 412 nationwide subjects sampled through daycare centers completed the 20-item checklist questionnaire. The construct validity of the NQ-P was assessed using confirmatory factor analysis, LISREL. Results: After analyses of exploratory factors, NQ-P items identified three dimensions of diet (balance, moderation, and environment). The three-factor structure accounted for 49.28% of the total variance. Standardized path coefficients were used as weights of the items. The NQ-P and three-factor scores of the subjects were calculated by the obtained weights of the questionnaire items. Conclusion: A food behavior checklist for preschoolers' NQ would be a useful and suitable instrument for evaluating nutrition adequacy and dietary quality of Korean preschoolers.

3레벨 NPC 인버터는 구조상 DC Link가 두 개의 커패시터로 직렬 구성되어 있어 두 커패시터 간의 전압 불균형의 문제가 발생한다. 중성점의 변동으로 인하여 스위치 소자의 소손과 제어기의 오작동 등 시스템의 안정도가 떨어지게 된다. 기존의 중성점 전압을 제어하는 오프셋 전압 인가 방식은 zero point 지점에서 불연속 스위칭 구간이 존재하기 때문에 중성점 제어가 불가능하다. 본 논문에서는 중성점 전압을 제어하기 위하여 DPWM 기법에서 중성점 전압을 제어하는 방식을 제안하였다. DC Link의 두 커패시터 전압 불균형이 발생하면 $60^{\circ}(+30^{\circ})$ DPWM 기법으로 Positive 벡터와 Negative 벡터의 스위칭 인가 시간을 조절하여 두 커패시터의 전압 균형을 이루게 한다. 시뮬레이션을 통하여 본 논문에서 제안한 방식에 대한 타당성을 검증하였다.
