Purpose: This study examined the distance between the coracoid process and the humeral head using an ultrasonography device when shoulder active contraction were applied according to the guided direction in the end range of shoulder mobilization. This study aims to provide essential data on treating shoulder disease patients. Methods: The subjects of this study were 20 adults with healthy shoulder joints. ultrasonography (US) equipment was used to examine shoulder joint mobilization under two conditions: (1) anteroposterior (AP) joint mobilization and (2) superoinferior (SI) joint mobilization. Shoulder active contraction was assessed in the end range. The distance between the coracoid process and the humeral head was measured. A linear probe was used for US; the frequency was set to 7.5MHz, and the US image display method was set to B-mode. The US measurement values were measured in (1) the starting position, (2) the end range position, and (3) the end range position of the shoulder active contraction, and the moving distance was drawn in a straight line through the US image. The distance was determined as the measurement value, and the average values were compared. Reults: The results were as follows: (1) the measured AP Joint mobilization increased by an average of .52cm from the end range of the joint mobilization with shoulder active contraction; (2) the measured SI Joint mobilization increased by an average of .49cm from the end range of the joint. Conclusion: When shoulder mobilization is applied, the distance between the coracoid process and the humeral head increases when muscle contraction occurs through shoulder active contraction in the end range, according to the therapist's guidance. Therefore, shoulder mobilization combined with shoulder active contraction is an effective treatment method for patients with shoulder injuries.

The aim of this paper was to estimate efficiency using a directional distance function to compare performances of bus agencies to determine if they have made efforts to operate efficiently and reduce emissions and accidents since public transportation reforms 2004. Drivers, mechanics, staff, buses, and fuel were used as input data and vehicle-kilometers (a desirable output), accident costs, and emission costs (undesirable outputs) as output data during June 2005. As a result, the efficiency with undesirable outputs was lower than the efficiency without undesirable outputs. However, the number of efficient agencies was more in case of the consideration of undesirable outputs. The reason is that the number of agencies whose possibility to reduce undesirable outputs are less than the possibility to reduce inputs was increasing, while the efficiency deviation among agencies was larger in case of the consideration of undesirable outputs. Meanwhile, the increase of CNG buses and operating speed and the improvement of mechanical efficiency had positive influence on the efficiency.

The objective of this paper is to develop a new energy transport system for district cooling application by using type 2 absorption cycle. Cold energy from the LNG storage system is utilized as the cooling source of the condenser and the rectifier. The pressures of the system, UAs of the evaporator and the desorber, and the inlet temperatures of the refrigerant to each component are considered as the key parameters. The results show that UA of the evaporator is more dominant parameter on COP than that of the desorber and the optimum system pressure for the demand side is estimated as 525 kPa. For the present system, it is recommended that the refrigerant inlet temperature of the evaporator be lower than $4.3^{\circ}C$ for long-distance transportation. It is concluded that the cold energy from the LNG storage system can be effectively applied to the long-distance transportation system for district cooling application with the type 2 absorption cycle. The optimum operation conditions are also predicted from the parametric analysis.

Objectives : The purpose of this study was to analyze factors related to the functional state of stroke patients after discharge from hospital. Methods : The data was provided from a hospital in Wonju, Gangwon-do. The subjects of the analysis were those who were admitted to the emergency room due to stroke from July to December 2016. The dependent variable was the patient's functional status as measured by the modified Rankin Scale(mRS). Independent variables were demographic factors (age, sex, and marriage status), transportation and distance factors (transportation, travel distance), inpatient factors (lengths of stay, Charlson Comorbidity Index (CCI), Tissue plasminogen activator, National Institute of Health Stroke Scale (NIHSS). Hierarchial regression analysis was applied for the analysis. Results : In the hierarchical regression analysis, Model 3, including socio-demographic factors, transportation, distance factors, and inpatient factors, was the best fitted model. It showed that functional status of stroke patients was positively associated with age, length of stay, CCI, NIHSS, and negatively associated with unmarried status. Conclusions : Results indicated that management of stroke requires care from the pre-disease stage, and a customized education program policy is needed for high-risk stroke patients who are older and have comorbid illness.

This study intends to analyze the trip and transportation structure of Seoul Metropolitan Area(SMA) where has been experiencing the rapid growth and the extra-concentration in the recent 2∼3 decades. By analyzing the trip and transportation structure which reveals the frame of travel flow phenomena on the real space, this paper evaluates the transporation policy realized in SMA for the last 10∼15 years. The policy implications of this paper are as follows; 1. The activities and the daily travel movement of SMA have been larger and more complex rapidly, but the transportation policy bas been poor. 2. The distribution of commuter's origins and destinatinos have been getting wider, and the distance between the home and the workplace longer. In short, the land use policy, the industrial policy, and housing policy have failed, and the coordination of those policies has been very poor. 3. The multi-center spatial structure was the official policy. Indeed, SMA has been reorgnized in such a way. But the implementation strategy was very poor. 4. Now, the for-business travels closely related with the multi-center structure, are increasing more and more rapidly. It is required that the strategic policy of mulit-center structure and the transportation policy should be coordinated. And as soon as possible, the more powerful mass transit system should be developed and constructed.

Determining the investment priority of the railway project is essential to keep its object of railway investment. [National railway construction plan] provide 4 major evaluation indicators and their weighting range in determining the investment priority of railway construction. Which are investment efficiency, inter-regional balance of development, network effects, government supporting policy. However this present criteria has inconsistency in determining economical feasibility of the railway transportation when applying the same evaluation indicator, investment efficiency, with the road transportation. The railway transportation is superior to road transportation in terms of transportation capacity and distance, while offering less carbon emissions. In spite of the prominent position of the railway transportation, it can be failed to obtain its proper investment priority when being determined under economical feasibility based. Therefore, this study analyzed the inconsistency under present evaluation criteria and proposed new evaluation method for the investment priority of the railway construction using AHP(analytic hierarchy process), while differentiate from the road construction. This method is optimized for only determining the priority of the railway construction itself under object of railway investment respectively.

Properties of sliding materials are dependent on the lithology because debris is the product of rock weathering processes. In order to characterize transportation behavior of debris dependent of debris types, this study selected 26 debris flows over three areas composed with different rock weathering types and topographic conditions. Analyses of lithology, weathering, and topographic characteristics were performed by detailed field survey. Based on the field survey data, transportation behavior of debris was studied at the aspect of the relationship of grain size and volume of debris as well as topographic conditions. According to the study results, change of slope angle is very influential factor on runout distance of debris among the topographic factors. Because the sliding velocity and the energy of debris are frequently changed and more irregular on an undulating slope, the unout distance of debris is larger than that of an uniformly dipping slope. Runout distance of debris is also influenced by volume and grain size of debris. Volume of debris in the gabbro is four or five times larger than that of the granite area because it is controlled by the lithology. Considered with grain size distribution, runout distance of debris is longer in the gabbro area which is composed with irregular grain size bearing large corestones than that in the medium grained granite area.

It is known that the transportation stress of market pigs can affect their carcass quality and that blood concentrations of glucose, creatine kinase (CK) and lactate dehydrogenase (LDH) are indicators of the transportation stress. Fifty-seven gilts and 57 barrows weighing approximately 110 kg were randomly assigned into six groups in a 3 [high (0.31 $m^2/100$ kg BW)-, medium (0.35 $m^2$)- and low (0.39 $m^2$)-stocking densities]${\times}2$[1 h vs. 3 h transportation time] arrangement of treatments. Blood samples were taken during transportation and after 2 h lairage. The percentage of "standing" animals during transportation was less in the low- than in the mediumor high-stocking density; the opposite was true for the "sitting" posture. Plasma concentrations of glucose, CK and LDH increased after loading and declined to the resting levels after lairage. Concentrations of CK and LDH were greater in the 3 h vs. 1 h transportation group. Moreover, the LDH concentration was less in the low- than in the medium- or high-density group. Also detected was a significant interaction between the stocking density and transportation time in all of these blood variables. The incidence of pale, soft and exudative (PSE) carcass was greatest in the high-stocking density group. Interestingly, the PSE incidence increased following the 3 h vs. 1 h transportation at the low-density, but not at the medium-density. Results suggest that the medium-density may be preferable to the lowdensity in the long-distance transportation.
