Metabolomics makes it possible to analyze the interrelationships between various signaling molecules based on the metabolic pathways involved by using high-resolution devices. This approach can also be used to obtain large-scale metabolic information to identify the relevant pathways for disease diagnosis and prognosis and search for potential biomarkers. In the fields of medicine and forensics, hair analysis is used to detect various metabolites in the body. Hair can be harvested readily in a noninvasive manner and is easier to transport and store than blood and urine. Another advantage from a forensic viewpoint is that hair reflects all the components of body fluids. In addition, because of the unique coating structure of hair, it can be used for measurements without changing or destroying its adsorbed components. In this review, the pretreatments for hair analysis, instrumental conditions and clinical applications are discussed. Especially, the clinical use of hair metabolomics in the diagnosis of various diseases and the limitations of the technique are described.

This study aimed to determine relationships among risk factors influencing container port operation using Bayesian network. Risk factors identified from prior studies were classified into five groups: human error, machinery error, environmental risk, security risk, and natural disasters. P anel experts discussed identified risk factors to fulfil conditional probability tables of the interdependence model. The interdependence model was also validated by sensitivity analysis and provided an interrelation of factors influencing the direction of each other. Results of the interdependence model were partially in line with results from prior studies while practices in the global port industry confirmed interrelationships of risk factors. In addition, the relationship between top-ranked risk factors can provide a schematic drawing of the model. Accordingly, results of this study can expand the prior research in the Korean port industry, which may help port authorities improve risk management and reduce losses from the risk.

Traditionally, road projects are initiated based on an assessment of their economic benefit, after which the environmental, social and governance effects are addressed discretely for the project according to a set of predetermined alternatives. Sustainable road infrastructure planning is vital as issues like diminishing access to road construction supplies, water scarcity, Greenhouse Gas emissions, road-related fatalities and congestion pricing etc., have imposed severe economic, social, and environmental damages to the society. In the process of addressing these sustainability factors in the operational phase of the project, the dynamics of these factors are generally ignored. This paper argues that effective delivery of sustainable roads should consider such dynamics and highlights how different aspects of sustainability have the potential to affect project sustainability. The paper initially presents the different sustainability-assessment tools that have been developed to determine the sustainability performance of road projects and discuss the inability of these tools to model the interrelationships among sustainability-related factors. The paper then argues the need for a new assessment framework that facilitates modelling these dynamics at the macro-level (system level) and helping policymakers for sustainable infrastructure planning through evaluating regulatory policies.

Memory allocation, which determines where memories are stored in specific neurons or synapses, has consistently been demonstrated to occur via specific mechanisms. Neuronal allocation studies have focused on the activated population of neurons and have shown that increased excitability via cAMP response element-binding protein (CREB) induces a bias toward memory-encoding neurons. Synaptic allocation suggests that synaptic tagging enables memory to be mediated through different synaptic strengthening mechanisms, even within a single neuron. In this review, we summarize the fundamental concepts of memory allocation at the neuronal and synaptic levels and discuss their potential interrelationships.

The objectives of this study are to conceptualize theoretically and to examine empirically the interrelationships among channel member's satisfaction, dependence, and performance being immanent between dealing partners, by integrating behavioral and economic approach to explain comprehensively the interrelationship between dealing partners in conventional marketing channel which have not studied in previous studies. To attain above objectives, latent variables and observed variables which had been immanent between licenced dealers and wholesalers in fish marketing channel were found out by exploratory study, and pre-test was conducted to select the proper variables, and then the model which could explain the interrelationships among the variables was set up. Three categories of varables were considered in this study. Namely, economic and noneconomic factors were identified as independent variable, the degree of satisfaction and dependence to dealing partner as intervening variable, and performance as dependent variable. The data for the study was obtained from a survey questionnaire of 214 licenced dealers who work in Pusan, Yusoo, and Kunsan and 190 wholesalers who work in whole country. Among them, 264 anayzable questionnaires(including 154 licenced dealers and 110 wholesalers)were collected. Statistical procedure to analyze the data was carried out by LISREL version 7. Major findings obtained from the results of the analysis are as follows. First, economic variables have a great influence on the degree of both licenced dealers' and wholesalers' satisfaction. Among economic variables, the degree of keeping wholesalers' payment date have greater influence on the degree of licenced dealers' satisfaction, and licenced dealers' faculty being able to send good fish in quality have greater influence on the degree of wholesaler's satisfaction than other variables. In short, licenced dealers make great account of wholesalers' payment, and wholesalers make great account of licenced dealers' faculty being able to send good fish in quality in dealing relationship. Second, noneconomic variables have more relevance to the degree of dependence in both sides than economic variables. This means that noneconomic variables as well as economic variables can be a factor to keep up the dealing relationship. Third, the degree of satisfaction and dependence have influence on performance in both sides. In the licenced dealers' side, the degree of dependence have greater influence on performance than the degree of satisfaction, on the other hand, in wholesalers' side, the degree of satisfaction have greater influence on performance than the degree of dependence. This means that wholesalers can easily substitute their dealing partner for another licenced dealer comparatively.

This research work was aimed at assisting isolated children to adapt their school life having examined the process of their changes by reducing isolation level and isolative behavior through means of implementing group art therapy program. To accomplish this purpose of research, 36 participants were selected from children attending Class 6, 4th Grade of D Elementary School located in Dajeon Metropolitan City, to which researcher was served as homeroom teacher. And the participants were asked to complete a survey that included social and emotional isolation scale test which was designed by Heh Sung-hee(1993) and 4 children marked more than 96 points were designated as isolated children. The group art therapy program exercised in this research was the one that reorganized by research to suit the research purpose based on the precedent works, and survey was conducted total 12 times, two time a week, within 60 minutes per time, between 6 September and 24 October 2006, and researcher conducted group art therapy program directly at Class 6, 4th Grade of D Elementary School using extra hours after school. And following analyses were performed in relation to results therefrom: First, to analyze changes of isolation level of isolated children Quantitatively, the results from pre and post test concerning social and emotional isolation scale were comparatively analyzed. Second, to analyze changes of psychological state of isolated children, projective drawing tests were performed using Kinetic House-Tree-Person(K-HTP) Drawing and Kinetic School Drawing(KSD) and results therefrom were comparatively analyzed. Third, to analyze Quantitatively what changes have been occurred in the isolated children during the course of forming interrelationships with group members while participating in group art therapy, proceedings were summarized per each stage of the program and analyzed accordingly. Fourth, results from researcher's observation of what changes have been occurred in the isolative behavior of isolated children before and after implementation of group art therapy were compared accordingly. Followings are resulting conclusions. First, group art therapy program reduced isolation level of isolated children. Second, group art therapy program changed the isolated children's psychological state into a stable and positive fashion. Third, isolated children became able to experience positive interrelations as well as establishment of new human relationships with group members during the course of participating in the group art therapy program. Fourth, group art therapy program reduced isolative behaviors of the isolated children. Therefore, conclusions could have been reached that the group art therapy program implemented in this research reduced isolative behaviors of the isolated children, and changed their anxious and depressed mental state into stable and positive ones, also established positive interrelationships as well as new human relationships. And, it will be able to expect a greater effect if a program which has been associated with their family could be proceeded along with continuous guidance and teaching having developed objective test tools that will discern isolated children.

The purpose of this paper is to do GIS-based suitable site selection using Scope for Growth index of Styela clava in Jindong Bay. The aquaculture of Styela calva is only conducted in Korea, especially Jindong Bay. Suspended culture of Styela clava was initiated in 2001 and the annual production reached 15,084M/T, but declined to 1,412M/T in 2005. The annual production was increased slightly to 2,484M/T in 2012 but the production is lower than the beginning yield. Scope for Growth(SFG) can indicate interrelationships between environment and organism growth index in aquaculture. GIS-based suitable site selection can be available by the concept of SFG, and fishery management system can be constructed for the sustainable production. As a result of the assessment of habitat suitability, Jindong Bay's SFG value ranges 0.054~0.57J/day and Styela clava farm's SFG values range 0.054~0.57J/day, either. The correlation between Styela clava farm's SFG and the actual production has a good result, as r=0.786, p<0.05. The construction of fishery management system using habitat suitability index ensures the reasonable site selection and the sustainable production in aquaculture farm. It introduces an objective method for the interrelationships between the environmental variation and the organism growth. Consequently, it can promote the decision making practices for the sustainable fishery management.

Interrelationships between yields of Burley 21 variety and meteorological factors such as precipitation, duration of sunshine, and evaporation in Suweon, Chungju, Daegu, and Jeonju were investigated during the growing seasons from 1976 to 1985. Cultivation period from the 41st to the 60th day after transplanting which showed the highest transpiration by the tobacco plant was corresponding to relatively dry season in Korea from the middle of May to early of June. The meteorological factors during the middle stage of the tobacco growth, especially the 41st to the 80th day after transplanting, seemed to have higher correlation with tobacco yield, than any other periods. This result implied that the middle stage of the growth when tobacco plant consume more soil moisture by transpiration proved to be a important growth stage having a great influence upon tobacco productivity.

The purpose of this study was to examine how various dimensions of social exclusion experienced by married immigrant women are affected longitudinally. Autoregressive cross-lagged analysis between sub-dimensions of social exclusion of married immigrant women was conducted to investigate the direction of interrelationships. The data were collected each year through a three-wave longitudinal survey from 2011 to 2013. The results showed that statically significant autoregressive effects appeared among economic exclusion, community exclusion, educational exclusion, and ethnic exclusion. The cross-lagged effects of the sub-dimensions of social exclusion showed that married immigrant women with higher levels of the economic exclusion tend to experience higher levels of the educational exclusion, and ethnic exclusion at the later measurement point, even when controlling for their previous level of social exclusion. It was found that economic exclusion as a more fundamental precedent factor positively predicted other dimensions of social exclusion. The results suggested that financial support and job-related services should be strengthened for active social inclusion of married immigrant women, and early intervention to prevent chronicization of social exclusion should be needed.
