In this paper, we try to define and classify the concepts of Convergent Research of Korean-Western Medicine (CRKWM) to clarify the goals of research. In addition, some suggestions that are necessary to promote the CRKWM were made. The results are as follows. First, the CRKWM should be used as a concept that refers to 'interdisciplinary research' jointly conducted by experts in both Korean and Western medicines beyond their own fields. Second, True CRKWM is an "eclectic combination of East-West" that combines the advantages of traditional Korean medicine and western medicine to create a new field; it is necessary to redefine the concept of 'Integrative medicine', which is used in different context by the traditional Korean medicine and western fields in Korea, as an "eclectic combination of East-West" type. Third, In order to promote the CRKWM, it is necessary to convert the current dual medical system of relativism to one of pluralism. Forth, In order for CRKWM to be promoted, methodologies, theories, and models that become the backbones of convergence should be developed. As of now, systems medicine and network science are the best fit. Fifthly, In order to promote convergent clinical research, the development of Korean-Western diagnostic model that integrates the pathologies of Western medicine and symptoms of Korean medicine is urgent. Lastly, Mutual understanding between Korean and Western medicine fields should be preceded in order for CRKWM to be stimulated.

PURPOSE: Many studies have reported the improvement of cognition through physical activity among subject with dementia. This study aimed to whether the current studies supports that physical activity intervention is efficacious on cognitive performance in subject with dementia. METHODS: Two independent reviewers searched National assembly library, RISS, KISS (2005-2015) using the concepts of dementia, exercise, and physical activity. We included randomized controlled trials that examined the efficacy of physical activity in subject with dementia. A meta-analysis was performed to estimate the effect sizes cognition with CMA (Comprehensive Meta-Analysis, version 2.2.064) soft-ware program. Nine randomized controlled trials were included, providing data from 133 individuals and excluding those failing to criteria of this study. RESULTS: The meta-analysis showed that physical activity intervention had a rather small effect sizes of 0.36 (95% confidence interval 0.14-0.59) on cognition performance in subject with dementia. Outcome measurement were MMSE-K (Mini-mental state examination Korean version) and LOCTA (Loewenstein Occupational Therapy Cognitive Assessment). We found heterogeneous among studies and there was difference between the studies (Q = 19.63, d(f)=12, $I^2= 38.88$). CONCLUSION: The present analysis suggests that physical activity interventions have the low effect sizes on cognition performance in subject with dementia Further studies will be required to develop the various programs for improving the cognitive performance in subject with dementia.

Changing concepts in fishery science increasingly are recognizing depletion of traditional stocks, utilization of alternate(non-traditional) species, demand for high quality products, and a total resource utilization approach. Innovative practices are occurring in fisheries processing wherein solid and liquid discharges are no longer treated as 'waste,' but rather as valuable feedstocks for recovery of a variety of value-added ('value enhanced') by-products. Among these are protein hydrolysates, soluble proteins and amino acids, proteolytic enzymes, flavor and flavor extracts, pigments, and biopolymers such as chitosan. Properties and applications of this deacetylated derivative of chitin are noted. Crustacean processing by-products are discussed in terms of their serving as materials for generation of natural flavors and flavor extracts, and products such as fish sauces using contemporary enzymatic techniques. Various food and feed applications of fisheries processing by-products are illustrated with increased usage seen in formulated diets for an expanding aquaculture market. Examples are given of aquaculture becoming increasingly significant in global fisheries resource projections. Critical issues in the international seafood industry Include those of seafood quality, processing quality assurance (HACCP), and recognition of the nutritional and health-related properties of fisheries products. A variety of current seafood processing research is discussed, including that of alternate fish species for surimi manufacture and formulation of value-added seafood products from crawfish and blue crab processing operations. Increasing emphasis is being placed on international aspects of global fisheries and the role of aquaculture in such considerations. Coupled with the need for the aquatic food industry to develop innovative seafood products for the 21st century is that of total resource utilization. Contemporary approaches in seafood processing recognize the need to discard the traditional concept of processing 'waste' and adapt a more realistic, and economically sound, approach of usable by-products for food and feed application. For example, in a period of declining natural fishery resources it is no longer feasible to discard fish frames following fillet removal when a significant amount of residual valuable flesh is present that can be readily recovered and properly utilized in a variety of mince-based formulated seafood products.

To reduce the size of structural members, high strength concrete has recently been utilized for structure such as ultra-high-rise buildings and prestressed concrete bridges in North America, and its compressive strength has gone up to 1300kg/$\textrm{cm}^2$. In Japan, research on high-strength concrete has been undertaken on a large scale by the national enterprise so-called New RC Project. And high-strength concrete with a design compressive strength over 450kg/$\textrm{cm}^2$ has recently been employed for high rised reinforced concrete building. As a result of the serious land availability situation of metropolitan areas in the world, buildings will become taller, and even higher strengths will be required. In the future, the utilization of high-strength concrete will spread widely through the development of new structural concepts, application of steels of a higher yield stress, silica fume, and other new materials. Considering these circumstance, the aim of this experimental study is to develop ultra-high-strength concrete with compressive strength over 1800kg/$\textrm{cm}^2$ with domestic current materials. There are so many factors which influence the manufacturing of ultra-high-strength concrete. The experimental factors selected in this study are mixing methods, curing methods, water-binder ratio, maximum size of coarse by silica fume. The results of this experimental study show that it is possible to develop the ultra-high-strength concrete with compressive strength over 1700kg/$\textrm{cm}^2$ at 28days, 1800kg/$\textrm{cm}^2$ at 56 days.
