ITS (Intelligent Transportation System) has been more popular but ITS project managements remain complex because of diverse stakeholders and multidisciplinary processes of ITS. The multidisciplinary process enforces specialized competencies on ITS project managers comparing to other system integration project managers. In this paper, we derived core competencies of ITS projects from previous researches, built the hierarchy of the competencies, and employed AHP (Analytic Hierarchy Process) surveying ITS project managers and auditors with the hierarchy. Finally, we analyzed the difference of evaluation model on ITS project manager between project managers and auditors using Mann-Whitney U test. Additionally we suggest a method of building MECE (Mutually Exclusive and Collectively Exhaustive) structure for AHP using the HoQ (House of Quality). We expect our model to give some inspirations for raising capable ITS project managers and selecting a proper project manager for an ITS project.

This research was conducted to evaluate the effects of cooking conditions on quality characteristics of Soo-Yuk, a traditional Korean food. The cooking conditions were as follows: boiled until the core temperature of a sample in $20^{\circ}C$ cold water reached at $75^{\circ}C$ (T1); boiled until the core temperature of a sample in $90^{\circ}C$ boiling water reached at $75^{\circ}C$ (T2); and boiled with sample from $20^{\circ}C$ to $100^{\circ}C$ and kept at $98^{\circ}C$ for 25 min (T3, Korean traditional method). The sample cooked at $90^{\circ}C$ water (T2) had the fast cooking time, and the highest cooking yield and moisture content. Soo-yuk boiled in $100^{\circ}C$ water (T3) showed the longest cooking time, the lowest cooking yield and moisture content, and the highest shear force. The instrumental color showed a significant difference among the cooking conditions. The sarcomere length of soo-yuk boiled in $100^{\circ}C$ water (T3) was the shortest, but the myofibrillar fragmentation index and thiamine content of the sample cooked at $90^{\circ}C$ (T2) were the highest. In sensory evaluation, the evaluation of soo-yuk boiled in $98^{\circ}C$ water (T3) was of superior flavor and overall acceptability.

The competition among insurance companies has become increasingly intense driven by the recent changes in financial environment. In this study, we (i) categorize the quality of life insurance services into the core service, relational services, and additional services, (ii) assess the impact of each service on repurchase intension, and (iii) investigate if customer satisfaction has a mediating effect. The research subjects are 215 life insurance customers who were selected from an online survey respondent population. Based on the analysis we performed by utilizing the SPSS 18.0, we concluded that (i) maintaining service of the core services, internal relationship of service personnel and insurance salesmen of the relational service and additional services have a positive impact on repurchase intention and (ii) In the relationships between repurchase intentions, the customer satisfaction is fully mediated by maintaining service and insurance salesman and partially mediated by additional service. The results of this study can be meaningful for both industry and academia, because these results can be utilized as useful evidence in understanding selection behavior of life insurance customers and deriving various strategies in business environment.

In order to prepare the technical fundamental in production of premium quality fruits of 'Niitaka' pears, we compared the quality parameters and storability of the fruits that had various fruit set position in a cluster. The fruits set on $4^{th}$ from basal part in fruit cluster had the largest fruit size. The weight of fruits set on the higher position than $4^{th}$ from basal part in fruit cluster showed decreasing tendency. The production rates of marketable fruits which had 500g to 899g in weight were the high in $3-5^{th}$ from basal part in cluster than those in other position. The differences of fruit height and diameter which represent balanced fruit shape also showed less difference in the fruits set on $4-5^{th}$ from basal part in cluster than the fruits set closely on basal part in cluster. The fruits set on $3-4^{th}$ from basal part in cluster showed lower rate in incidence of core breakdown and pithiness disorder during 4 months of cold storage than those on the closer position to basal part in cluster.

We investigate the effect of preharvest spray of aminoethoxyvinylglycine (AVG), an inhibitor of ACC synthase activity, on fruit quality of 'Wonhwang' pear (Pyrus pyrifolia Nakai). And the effects were compared with ethephon which releasing ethylene to elucidate treatment efficacy of ethylene biosynthesis inhibitor on Asian pears. Chemicals were sprayed on 30 days before harvest with AVG (75 and 150 mg/L) and ethephon (100 mg/L), respectively. Highest flesh firmness during 21 days of shelf-life at $25^{\circ}C$ after 30 days of cold storage was attained in the fruit treated with 150 mg/L AVG (26.5N) when compared with untreated control (16.7N), while the fruits treated with 100 mg/L ethephon completely lost their marketability within 14 days of shelf-life by mass drop of firmness down to 11.6N. Low incidence of physiological disorders including pithiness and core browning were attained at the fruits treated with 150 mg/L AVG when we compared with untreated control. No occurrence of mealiness found in the fruits treated with AVG but ethephon treated fruits showed 36.4% during 14 days of shelf-life. Consequently, AVG spray at the concentration of 150mg/L on Asian pear 'Wonhwang' fruit regarded as useful preharvest management approach for keeping quality during marketing period after simulated exportation.

An ontology as the core element of Semantic Web is a formal specification of a conceptualization of shared domain knowledge. The use of well-defined ontologies can increase the quality of interoperable information systems in the area of Semantic Web. However, in practice, it is not easy to develop high-quality ontologies which have no errors. Therefore, with methodologies for ontology design, various methods or tools for ontology analysis supporting for error-detection might be very helpful for ontology developers. In this paper, we propose a novel approach for analyzing the core constructs of ontology based on the Formal Concept Analysis and develop a tool that supports error-checking ontologies. Our approach can serve not only as a guidance to modify the existing ontologies, but also as a valuable tool in developing high-quality ontologies.

Imaging through multicore fiber (MCF) is of great significance in the biomedical domain. Although several techniques have been developed to image an object from a signal passing through MCF, these methods are strongly dependent on the surroundings, such as vibration and the temperature fluctuation of the fiber's environment. In this paper, we apply a new, strong technique called deep learning to reconstruct the phase image through a MCF in which each core is multimode. To evaluate the network, we employ the binary cross-entropy as the loss function of a convolutional neural network (CNN) with improved U-net structure. The high-quality reconstruction of input objects upon spatial light modulation (SLM) can be realized from the speckle patterns of intensity that contain the information about the objects. Moreover, we study the effect of MCF length on image recovery. It is shown that the shorter the fiber, the better the imaging quality. Based on our findings, MCF may have applications in fields such as endoscopic imaging and optical communication.

The assessment of patient status in palliative medicine is essential for determining treatments and for clinical outcomes. The objective of assessment tools is to raise the quality of care for individual patients and their families. There are a number of tools available to assess pain, non-pain symptoms and quality of life. The tools are either uni-dimensional or multi-dimensional measures. Unfortunately, however, no single tool is recommended to be a superior to others in symptoms or quality of life assessment. Therefore, to select an appropriate assessment tool, one should consider the time frame and unique characteristics of tools depending on purpose and setting. The combination of prognostic index is highly recommended in prognostication, and web-based prognostic tools are available. Recently, a new objective prognostic score has been constructed through multicenter study in Korea. It does not include clinicalestimates of survival, but includes new objective prognostic factors, therefore, anyone can easily use it. For beginners in palliative medicine, relatively easy-to-use tools would be convenient. We recommend Eastern Cooperative Oncology Group performance status to assess functional status, numeric rating scale for pain assessment and the Korean version of brief pain inventory for initial pain assessment. Asking directly with numeric rating scale or the Korean version of MD Anderson Symptom Inventory would be desirable to assess various symptoms together. We think that European Organization Research and Treatment Quality of Life Questionnaire Core 15 for Palliative Care is good to assess the quality of life, while Objective Prognostic Score is convenient as prognostic index for beginners.

Pneumonia is an important cause of morbidity and mortality. Since 2014, the Health Insurance Review and Assessment Service (HIRA) has assessed the overall quality of care among hospitalized adult patients with community-acquired pneumonia (CAP) provided by all medical institutions in Korea. A committee of the Korea Academy of Tuberculosis and Respiratory Diseases developed the hospital inpatient quality measures set for CAP consisting of eight core measures and five monitoring measures. The composite measure score was calculated. The medical records of hospitalized adult patients ages 18 years or more with CAP from October to December 2014 were evaluated. The data of 523 hospitals (42 tertiary hospitals [8.0%], 256 general hospitals [49%], and 225 hospitals [43.0%]) and 15,432 cases (tertiary hospitals, 1,673 cases [10.8%]; general hospitals, 8,803 cases [57.1%]; hospitals, 4,956 cases [32.1%]) were analyzed. We found large variations among institutions in terms of performance of care measures for CAP. For the composite measure score, the mean value was 66.7 (tertiary hospitals, 98.5; general hospitals, 79.2; hospitals, 43.8). Despite significant differences in measure scores between tertiary, general hospitals and hospitals, no significant differences were found in mortality between hospitals. Further studies are needed to determine the care measures appropriate for CAP.
