This study aims to examine what factors park users value in urban parks and to find ways to elevate user satisfaction for the creation and usage of an urban park. To achieve this, the study relied on two methods: the descriptive method of researching publications and related scholastic writings, and the empirical study method including a survey of present condition and interviews with users. The result shows that the 'sense of nature' is more important than 'functional facilities' in urban natural parks and 'management part like safety and cleanliness of park' is more important than 'utilizing facilities' in urban neighborhood parts. Generally, the importance rating of urban parks visitors felt in them were higher than the satisfaction rating, in terms of living surroundings. Factor analysis resulted in six factors in a natural park and in eight factors in a neighborhood park. Regression analysis in a natural and a neighborhood park showed a positively correlated factor: benefits sought, suggesting that people recognize the importance of urban parks through the benefits they gain in them and the satisfaction they find in urban parks depends on utilizing facilities. Therefore, in urban natural parks, people will find greater satisfaction through pursuit of the benefits they are seeking; improvements to park facilities should address the benefits that park users are seeking.

The 181,000 DWT Bulk Carrier has a different deck house type, which is not typical for previous bulk carriers, to meet the new international rules for bulk carriers. This new deck house has much smaller transverse breadth than the hull's transverse breath, resulting in large levels of the transverse response of the deck house. In addition, the longitudinal response of the funnel showed rather a large magnitude of vibration, which are excited by the ship's main excitations such as the main engine H-moment and the propeller surface forte when the ship operates at the NCR and the MCR speeds In the ballast condition. To solve these issues, the global forced vibration analysis has been performed for the ship and the ship structure has been modified to reduce the vibration level by increasing the girder depth and adjusting the engine room tank arrangement.

This study aims to examine what factors park users value in urban natural parte and to find ways to elevate user satisfaction for the creation and usage of an urban natural park To achieve this, the study relied on two methods: the descriptive method of researching publications and related scholastic writings, and the empirical study method including a survey of present condition and interviews with users. 'Breathing fresh air' and 'cleanliness' were the most important items and play facilities, cultural facilities, and landscape facilities were of lower orders of importance. This suggests that the 'sense of nature' is more important than functional facilities in urban natural parte. The importance of urban natural parks and the satisfaction visitors felt in them were measured, with mean results of 5.86 and 3.88, respectively, in terms of living surroundings. The impotance rating is higher than the satisfaction rating. Factor analysis resulted in six factors: benefits sought facilities for use, pleasant use, safety, accessibility, and management. Correlation and regression analysis showed only one positively correlated factor: benefits sought, suggesting that people recognize the importance of urban natural Parte through the benefits they gain in them and the satisfaction they find in urban parte depends on utilizing facilities. Therefore, in urban natural parks, people will find greater satisfaction through pursuit of the benefits they are seeking; improvements to park facilities should address the benefits that park users are seeking.

With the increasing of urban electricity demand, making the most use of the power cable carrying capacity has become an important task in power grid system. Contrary to the rated ampacity obtained under extremely conservative conditions, this paper presents the various steady value of cable ampacity by using the changing surrounding parameters under operation, which is based on cable ampacity calculation equation under the IEC-60287 standard. To some degree, the cable ampacity analysis of actual surroundings improves the transmission capacity of cables. This paper reveals the factors that influence cable ampacity such as insulating layer thickness, allowable long-term conductor temperature, the ambient temperature, soil thermal resistance coefficient, and so on, then gives the class of the influence of these parameters on the ampacity, which plays a great role in accurately calculating the real-time ampacity and improving the utilization rate of cable in the complex external environment condition. Furthermore, the transient thermal rating of the cable is analyzed in this paper, and temperature variation of the conductor under different overload conditions is discussed, which provides effective information for the operation and control of the system.

In the current domestic, many industrial accidents have happened. And these are analyzed according to several factors. But it is difficult that they evaluate their business safety. Thus, we conducted a study on business specific safety assessment techniques in order that business know their safety level and perform appropriative safety activities. Study methods are survey and AHP (Analytic Hierarchy Process). Each specific weighting factors to calculate the survey was conducted for safety and consulting experts (20 persons). Weight factor was used to AHP decision support as one of the ways through a number of alternatives to the ratings for the Minesota Multiphasic. Factors are each type of industry, specific industrial scale, disaster type and strength, worker age and tenure period, and region. First, survey was conducted with 20 professionals to estimate the weighting factors. Weights between factors using the AHP analysis tool based on the mean values were calculated. Second, last 3 years between the industrial accidents statistics were used to calculate the weights for each of the rating factors in the Occupational Safety and Health Agency. Grade weights between each factor which was based on the rating of each factor was calculated as the average of three years. Finally, the weights between each factor and the grade weights for each factor using the safety level of the enterprise were calculated so that you can evaluate the weighting.

Lumbar spinal stenosis (LSS) is a common degenerative spinal condition that can have unpredictable improvement and worsening of symptoms which include low back pain, radiating pain, claudication, and degenerative lumbar scoliosis affecting quality of life. In this study, thread embedding acupuncture (TEA) was used as a conservative treatment for LSS in combination with complex Korean medicine treatments (acupuncture, herbal medicines, and physical therapy). The treatment was evaluated using the numerical rating scale, walking distance and duration, and inclination of radiological lumbar scoliosis according to antalgic posture. TEA was performed 27 times between June 8, 2020, and March 16, 2021. The patient showed improvement in numerical rating scale score from 7 to 2, pain-free walking distance from 10 m to 900 m, and scoliosis inclination following treatment. The findings of this study suggest that TEA may be helpful in the treatment of LSS.

Low head, ogee spillways is popularly used to defense against floods as well as to provide water for irrigation. Spillway is also used to assess compliance with water quality regulations by controlling amount of discharge to the downstream of a channel. For the purpose of water resource management and/or environmental aspects as explained above, the flow discharge through spillways need to be correctly rated as a function of geometry and hydraulic variables. Typically, four flow conditions are encountered during the operation of spillway: (a) uncontrolled free flow (UF); (b) uncontrolled submerged flow (US); controlled free flow (CF); and controlled submerged flow (CS), and each condition has a unique rating equation. However, one of the tricky part of the spillway operation is finding correct flow type over the spillway because structures can operate under both submerged and free flow conditions, and the types are continuously changing over time depending on the amount of discharge, head water and tail water elevation. Quite obviously, if the wrong rating curve relationship is applied because of misjudgment of the flow type due to a transition, a serious error can occur. Thus, an hydraulic model study of one of spillway structure located in South Florida was conducted for the purpose of developing transition relationships. In this presentation, US to UF transition is highlighted.
