Plasma levels of lipoproteins were observed in vegetarians and non-vegetarians in order to compare the values between the two groups with different dietary habits, and among different age groups. All 162 vegetarians and 95 non-vegetarians were selected for this study. In detail, male vegetarians subjects were devided into three groups according to their ages, 20's, 30's and 40's. And three control groups were also selected at matching basis. Two groups each were selected for female subjects in their 20's and 40's. All ten groups were adopted and the lipids levels were compared appropriately. Plasma $pre-{\beta}-lipoprotein$ levels of vegetarians and non-vegetarians were not significantly in all groups. And plama ${\alpha}-lipporoten$ levels of non-vegetarians were higher than the ones for vegetarians as compared with male of 20's, male 30's and female of 40's, and it was not significantly as compared with female of 20's. And plasma ${\beta}-lipoprotein$ levels of vegetarians were significantly lower than the ones for non-vegetarians in all groups. Most of plasma lipoprotein levels measured were found to be lower in vegetarians and tended to be higher age groups of both vegetarians and non-vegetarians. And plasma ${\alpha}-lipoprotein$ levels which is known to be adversely related to atheroscherosis were higher in non-vegetarians, it can be concluded in this study that the plasma lipoprotein levels of non-vegetarians under Korea dietary patterns are quite acceptable.

The Ministry of Maritime Affairs and Fisheries is supporting the "Environmentally Friendly Fisheries Promotion and Private Assistance Project" to increase production of eco-friendly, high-value-added foods. Private-backed operators selected for the project will have an economic opportunity to build, expand or refurbish eco-friendly fishing grounds. To facilitate this, the scope of project support was expanded after 2015 and an opportunity was prepared for private subsidy projects to grow to a new level in terms of quality and quantity by switching to a public offering project. However, starting in 2017, demand from the private sector will plunge and selected projects will be delayed or the project implementation rate will be lowered. It was a time for subsidy-related laws and systems to be reinforced but private subsidy projects do not temporarily shrink simply due to the increased administrative burden on private subsidy operators on subsidy management. It plans to review the correlation between laws and systems related to the construction of fish farms and suggest ways to enhance the efficiency of implementation so that economic advantages, the biggest advantage of the private subsidy project, can be recovered within the current legal system.

Currently, there is no available tool that rapidly diagnoses pine wood nematode (PWN)-infected pine trees in the field. In this study, we synthesized and purified PWN Galectin, which might be an antigen specific to PWN, using the Baculovirus expression system. We used PWN Galectin as an antigen for generating 1,464 fusion hybridoma cell lines secreting monoclonal antibodies (Mabs). Among them, we selected 62 fusion hybridoma cell lines showing high reactivity to PWN Galectin. We further selected 12 fusion hybridoma cell lines showing high reactivity to the standard PWN-infected pine tree phosphate buffered saline (PBS) extract. Additionally, two fusion hybridoma cell lines showing no or extremely low reactivity were used as controls. The selected fusion hybridoma cell lines were subjected to limiting dilutions for selecting and establishing Mab-secreting cell lines showing higher reactivity to the standard PWN-infected pine tree extract than to the standard normal pine tree PBS extract. Moreover, the selected fusion hybridoma cell lines were further selected based on their higher reactivity to PWN protein extracts than to three non-pathogenic nematode protein extracts. The Mab-secreting cell lines established in this study could be used to develop rapid diagnostic tools that can be used in the field or in laboratories for detecting PWN-infected pine trees or PWN.

This research is motivated by the question, "Where, when, and through what mode does an individual passenger moving within a subway station use to travel from starting to final destinations ?" To answer this, the stations passed by the individual passenger, the path taken, and modes used need to be known beforehand. In the metropolitan integrated public transportation fare system, Automated Fare Collection System(AFC) can be a source of information on transit modes, stations, and paths of individual passengers. AFC calculates a fare for the passenger based on travel data such as boarding and alighting stations, time, and mode used. In this research, an Selected Station Analysis(SSA) method, in which AFC data is used to observe passenger movement in the metropolitan public transportation subway station from the perspective of subway transfer stations, is proposed. SSA subdivides individual passenger movement in transfer stations and analyzes initial station/time and final destination station/time information using the trip chain perspective.

Purpose - This study aims to show that consignments can enable supply chain collaboration, based on the review of selected studies, and aims to investigate its potential to be a better collaboration program, through an analytical comparison with other collaboration initiatives. Research design, data, and methodology - This study uses a literature review on selected studies that researched consignments. In addition, based on the proposed framework, the current consignment process and other well-known collaboration programs are analyzed in terms of three key collaboration aspects. Results - Most studies employ simple research in terms of their purpose and methodology. An analysis with the proposed framework indicates the potential of consignments to foster supply chain collaboration. Conclusions - Based on the literature review, this study suggests that future research needs to aim for diverse research goals and conduct sophisticated research on consignments. An analysis with the proposed framework shows that consignments would be more effective for supply chain collaboration if active information sharing and joint decision-making are implemented.

Geopolymer Concrete is typically proportioned with activator solution leading to moderately high material cost. Such cost can be enduring in high value added applications especially when cost savings can be recognized in terms of reduction in size of the members. Proper material selection and mix proportioning can diminish the material cost. In the present investigation, a total of 27 mixes were arrived considering the mix parameters as liquid-binder ratio, slag content and sodium hydroxide concentration to study the mechanical properties of geopolymer concrete (GPC) mixes such as compressive strength, split tensile strength and flexural strength. The derived statistical Response Surface Methodology is beleaguered to develop cost effective GPC mixes. The estimated responses are not likely to contrast in linear mode with selected variables; a plan was selected to enable the model of any response in a quadratic manner. The results reveals that a fair correlation between the experimental and the predicted strengths.

In this paper, a specified number of actuators are selected from a given set of admissible actuators. The selected set of actuators is likely to use minimum control energy while required output variance constraints are guaranteed to be satisfied. The actuator selection procedure is an iterative algorithm composed of two parts; an output variance constrained control and an input variance constrained control algorithm. The idea behind this algorithm is that the solution to the first control problem provides the necessary weighting matrix in the objective function of the second optimization problem, and the sensitivity information from the second problem is utilized to delete one actuator. For variance constrained control problems, by considering a dual version of each control problem an efficient algorithm is provided, whose convergence properties turn out to be better than an existing algorithm. Numerical examples with a simple beam are given for both the input/output variance constrained control problem and the actuator selection problem.

In this paper, we propose a dynamic battery equivalent modeling of lithium-ion batteries that can be applied to the battery simulator. In order to apply battery model to battery simulator, the profile of battery model should be equal to that of actual battery. Therefore, the equivalent model was selected by considering the transient and steady-state characteristics of lithium-ion batteries. Also, to obtain transient-state behavior of the battery, the RC values of the battery are selected through the lithium-ion battery charge/discharge experiments. The validity of proposed battery model is verified from the experimental results.
