Objectives: The purpose of this study is to investigate the emotional characteristics of the Sasang constitution with the Core Seven Emotions Inventory (CSEI) and Temperament and Character Inventory (TCI). Methods: A total of 224 participants were assessed with a Sasang Constitutional Analysis Tool (SCAT) for Sasang Constitution Diagnosis, and completed the Core Seven Emotions Inventory (CSEI) and Temperament and Character Inventory (TCI). Results: 1. From the results of the CSEI, Soeumin showed a significantly higher fear (恐) score than the Soyangin. 2. From the results of the TCI, Soeumin showed a significantly higher harm avoidance (HA) score than Taeeumin and Soyangin. Moreover, the Soyangin showed a significantly higher reward dependence (RD) score than Taeeumin and Soeumin. 3. In the correlation tests of the CSEI sub-scales, there was negative correlation between joy (喜) and other emotions, which are thoughts (思), depression (憂), sorrow (悲) and fear (恐). There were positive correlations between the emotions except joy (喜). 4. In the correlation tests of the TCI sub-scales, there was negative correlation between HA and persistence (P), and HA and SD. Moreover, there was a positive correlation between RD and cooperativeness (C) and between P and self-directedness (SD). 5. In the correlation tests of the TCI and CSEI, joy (喜) showed a negative correlation with HA and a positive correlation with P and with SD. Anger (怒) showed a negative correlation with C and other emotions except joy (喜) showed a negative correlation with RD. Conclusions: The differences of psychological characteristics in Sasang Constitution were shown with CSEI and TCI from this study.

Inventory survey is process collecting data about cut slope. It's different from inspection. It contains not only basic information about cut slope, especially location, GPS positioning, height, length, weathering, joint direction, water conditions but also level of danger and damage. Collected data are being used get at status about cut slope along national roads. And It helps judging about priority of detailed investigation. According to results of analysis, we found better method about maintenance of cut slope. Later on, if inventory research is finished, we will understand characteristics of collapse slopes.

This papaer analyzes a system with consists of two workstations that are separated by finite buffer storage. In this system, we assume that the processing time in each station in a random variable and each station is not vulnerable to failure. To control the in-process inventory in the serial production system we use the (R, r) policy which is similar to the (s, S) policy in the inventory theory. Under the (R, r) policy the preceding station is forced down when the inventory level in the buffer reaches R and starts operation again when the inventory level falls to r. For the model developed, we analyze the system characteristics and the system performances.

Battery switching EVs are considered to be a promising alternative to overcome long charging time problems in the EV adoption. The purpose of this research is to develop integrated model for battery inventory and battery switching waiting times. Due to complexity of exact analysis, a practical approximation method is developed, which provides close results to exact values. Numerical experiments show that there exist trade-offs between the battery inventory level and the number of switching stations. The proposed model can be applied to evaluate and select the minimum cost alternative in implementing the battery switching stations.

We analyze how firms' global production activities affect their inventory supply and financial performance in regards to its production location. For the analysis, we use information on global production quantities of 3,076 Korean multinational firms that operate business in Europe and Asia through foreign direct investment (FDI) from 2006 to 2013. Our estimation results show that an increase in global production ratio, measured by global production/total production, decreases inventory supply and financial performance of firms that produce in European countries, while it decreases financial performance of firms that produce in Asian countries. Although our results indicate that global production decreases financial performance of firms that produce in Europe and Asia, we find that its negative effects on financial performance are different based on the market demand uncertainty.

Generally, in deriving the solution of economic production quantity (EPQ) inventory model, we consider the demand rate and deterioration rate as constant quantity. But in case of real life problems, the demand rate and deterioration rate are not actually constant but slightly disturbed from their original crisp value. The motivation of this paper is to consider a more realistic EPQ inventory model with finite production rate, fuzzy demand rate and fuzzy deterioration rate. The effect of the loss in production quantity due to faulty/old machine have also been taken into consideration. The methodology to obtain the optimum value of the fuzzy total cost is derived and a numerical example is used to illustrate the computation procedure. A sensitivity analysis is also carried out to get the sensitiveness of the tolarance of different input parameters.

In this paper, it is identified that the optimal level of each performance measures (service and inventory level) is not sensitive to an uncertain environment under JIT Kanban system designed by Moeeni. Moreover, it is proposed that the optimal design method considering multiple performance characteristics is the optimal level decision method according to the relative importance differences of each performance when there exist multiple performance characteristics. The result from the simulation analysis shows that the number of Kanban for stage 3 (final process) and stage 2 is increased at the service level. It is found that the expected loss is minimal when the cycle time decreases and the container size increases. However, the stage 1 is not affected by the number and cycle time of Kanban. It is thus important to consider carefully the cycle time and the container size of the Kanban to satisfy the demand in right time. In case of inventory level, the working inventory level decreases when the container size is decreased and the working inventory level also decreases slightly when the cycle time of the Kankban is increased in stage 1 and 2.

The Korean version of the Child Development Inventory (K-CDI) is a developmental screening test for children functioning in the one-six year range. Based on parent-report, the inventory assesses child developmental functioning in the areas of social, self-help, gross motor, fine motor, expressive language, language comprehension, letter and number skills, general development, and various symptoms and behavior problems. Participants were recruited from childcare centers and private groups and finally 1,143 children and their mothers from 4 locations nationwide participated in this study. Through analysis of item response rate of 270 items in 9 areas, new norm was formed. Reliability determined by internal consistency were relatively high (Cronbach ${\alpha}=.95$). Intercorrelations among sub-scales (range: .49-.96) indicated the construct validity, and the correlation between K-CDI and other screening tests supported the concurrent validity.

We conduct the future studies suggested by Park and Seo [3]. They considered a seat inventory control problem in which flights depart sequentially during a similar time-interval and passengers purchase available seats depending on individual customer choice behavior. Customer choice behavior can lead to one among a horizontal shift, a diversion-up, and a booking loss when a desired fare class is unavailable. We investigate how seat availability calculation method, booking limit control mechanism, seat inventory capacity, number of booking class, type of seat demand influence on revenues in an airline industry through thorough computer simulation experiments.

Research with parents of children with Asperger Syndrome was conducted to assess whether the level of positive parental attachment correlated positively with positive parenting behaviors and negatively with negative parenting behaviors. Participants were recruited from internet. The Parental Bonding Inventory measured parents' perception of their bonding or attachment with three aspects of their own parents: warmth, control, and care. In the Parenting Behavior Inventory, parents reported recent interaction/reaction behaviors with their child, and results focused on two aspects of parenting, supportive/engaged and hostile/coercive behaviors: each identified as problematic to parenting and attributable to a variety of specific parenting behaviors. Analysis of demographic variables for correlations with positive parenting behaviors and negative parenting behaviors were carried out by Pearson correlations. Two separate standard multiple regressions, one for positive parenting behaviors and one for negative parenting behaviors, were conducted. Findings support the hypothesis that positive early attachment experience of parents has a significant impact upon their own positive parenting skills with their child with Asperger Syndrome. However, multiple regression of negative parenting behavior found no significant negative contribution by parental attachment. Demographic variables proved to be important.
