"Know thyself" is one of the most famous ancient proverbs. We need to know ourselves to understand others and find true ourselves. Enneagram is one of the tools we can use to do it. It has drawn more and more attention from people by its effectiveness and spiritual depth. It has been widely promoted in both business management and spirituality contexts. It has many concepts to be understood. Holy ideas and virtues are understood to be restored to find our true self which is the purpose of using the Enneagram. Actually, holy ideas and virtues are similar with character qualities which comprise character. In this paper, holy ideas and virtues are matched with corresponding character qualities. To promote transformative process of character development through Enneagram, an app was designed. It has 2 levels. Level 1 is to find personality type and show corresponding character qualities of 9 personality types to users. Level 2 is to find subtypes and Enneagram Levels of Development for further purpose.

The purpose of this paper is to discuss the methodology of optimizing delivery route scheduling using a capacity integer linear programming problem model developed to a previous case study. The methodology suggests a two-stage decision: the first, automatic, where the manager will obtain guidance generated by the solution of the linear programming model, later they could use post-optimization techniques to fine tune to the best operational solution. This study has the goal to reduce the size of service companies' ground transportation fleets, aiming not only to reduce costs and increase competitive advantages but also to lower levels of air pollution and its consequences, traffic and, therefore, the levels of carbon dioxide, allowing for a reduction in envir onmental disasters.

Adipocyte differentiation in human bone marrow mesenchymal stem cells (hBM-MSCs) is not as efficient as that in murine pre-adipocytes when induced by adipogenic agents including insulin, dexamethasone, and 3-isobutyl-1-methylxanthine (IDX condition). Therefore, the promotion of adipocyte differentiation in hBM-MSCs has been used as a cell culture model to evaluate insulin sensitivity for anti-diabetic drugs. In hBM-MSCs, $PPAR{\gamma}$ agonists or sulfonylurea anti-diabetic drugs have been added to IDX conditions to promote adipocyte differentiation. Here we show that troglitazone, a peroxisome proliferator-activated receptor-gamma ($PPAR{\gamma}$) agonist, significantly reduced the levels of anti-adipogenic $PGE_2$ in IDX-conditioned hBM-MSC culture supernatants when compared to $PGE_2$ levels in the absence of $PPAR{\gamma}$ agonist. However, there was no difference in the mRNA levels of cyclooxygenases (COXs) and the activities of COXs and prostaglandin synthases during adipocyte differentiation in hBM-MSCs with or without troglitazone. In hBM-MSCs, troglitazone significantly increased the mRNA level of 15-hydroxyprostaglandin dehydrogenase (HPGD) which can act to decrease $PGE_2$ levels in culture. These results suggest that the role of $PPAR{\gamma}$ activation in promoting adipocyte differentiation in hBM-MSCs is to reduce anti-adipogenic $PGE_2$ levels through the up-regulation of HPGD expression.

In a SoC (system-on-chip) design, a design complexity is a big bottleneck. In order to overcome the design complexity, platform based design method is widely adopted for designers. Most complex SoCs need a heterogeneous design development environment for hardware and software co-design. In this paper, we discuss about some kinds of verification approaches with platform based design methodology at various abstraction levels of SoC design. We separate the verification process to two steps according to the different levels of verification. We employ a flexible SoC design environment to support simultaneous hardware and software development. We demonstrate the verification strategy of a target SoC design, IEEE 802.11a WLAN SoC.

This paper examines the empirical magnitude of local human capital spillovers in Korea during the 1980s and mid-1990s. Local human capital spillovers exists if plants in regions with a higher level of human capital can produce more given their own amount of input (Moretti 2004c). In particular, this paper explores an educational reform in South Korea which exogenously induced a large amount of variation in regional human capital levels. Using annually collected plant level data, I explore the effect of changes in the regional human capital levels induced by this reform on plant productivity in Korea. My results suggest that this effect is limited. I find a positive correlation between a regional level of human capital and plant productivity. However, after further addressing endogeneity using an instrumental variable, the effect of the overall regional human capital level on productivity decreases and becomes statistically insignificant.

Purpose: This study examined post-traumatic stress (PTS) and the factors affecting it among general hospital nurses after the MERS(Middle East Respiratory Syndrome) epidemic. Methods: Data were collected from 170 nurses who worked at general hospitals since the first reported MERS outbreak. The IES-R-K assessed PTS. Data were analyzed using SPSS. Results: The mean PTS level was 7.80 points (range: 0~88); 7.1% of the participants were at a high risk. Nurses who had been in contact with patients suspected or diagnosed with MERS had high post-traumatic levels; those who had been quarantined during the MERS outbreak had relatively higher PTS levels. Shift-work nurses had higher PTS levels than those with fixed working hours. Above charge' nurses stress levels were higher than staff nurses' stress levels. The results showed that factors including contact with an MERS-suspected or diagnosed patient, position at work, and working status of MERS-affected nurses explained 16% of the PTS. Among the main variables, nurses' above charge position was the greatest factor affecting PTS. Discussion: It is necessary to develop intervention studies and programs considering these variables. Furthermore, development and implementation of differentiated programs should be done considering the position of above charge nurses.

Objective: Pork belly is considered as the most commercially important and preferable primal cut by consumers worldwide. Thus, this study was conducted to determine the effects of fat levels on the meat quality characteristics of pork bellies. Methods: Seventy-eight growing-finishing pigs collected from different commercial pig farms were slaughtered and used in the present study. After slaughter 24 h, bellies were fabricated according to the Korean Pork Cutting Specification, and immediately sampled for analysis of their fat content. Based on the fat levels, the bellies were segregated into three different groups: low fat (LF, fat ≤20%, n = 15), medium fat (MF, fat 21% to 30%, n = 30), and high fat (HF, fat ≥31%, n = 33). The bellies were then analyzed for meat quality traits, fatty acids, flavor compounds and eating quality properties. Results: The HF group had lower moisture and cooking loss levels compared to the other groups (p<0.05). The LF group presented higher proportions of polyunsaturated fatty acids compared to the other groups (p<0.05). The LF group showed higher amounts of the Maillard reaction-derived flavor compounds (e.g., 2,5-dimethyl pyrazine, 2-ethyl-3,5-dimethyl, and 4-methylthiazole) associated with meaty and roasty flavors whereas, the HF group showed higher amounts of oleic acid- derived compounds (e.g., nonanal and octanal) associated with the fatty and oily flavors. Interestingly, significantly higher scores for all the eating quality attributes (flavor, juiciness, tenderness, and overall acceptance) were found in the HF group compared to those in the LF or MF group (p<0.05). Conclusion: The high-fat bellies (fat ≥31%) had a better technological quality and eating quality compared to the low-fat bellies (fat ≤20%). Thus, increasing the fat content may improve the technological quality and eating quality traits of pork bellies, however, this increase may also result in more trimmed loss due to excessively deposited body fat.

In this study, several rheological properties of binder pastes and concrete are investigated for the development of commercially available fly ash super-flowing concrete. Fly ash contents with 5 leves(0, 10, 20, 30, 40%), slag contents with 6 levels(0, 5, 15, 25, 35, 45%), and water-binder ratios with 4 levels(30, 33, 36, 39%) are selected for test variables to evaluate the super-flowing characteristics of binder pastes. For the estimation of the workability of super-flowing concrete, slump flow, funnel time, box height, and L-flow are measured and compared. As the results, the flow is decreased and the viscosity is increased with increasing fly ash content. Super-flowing concrete is succesfully produced with 30% fly ash replacement.
