Due to the increased demand for safety and security requirements on the port infrastructure, the harbor tranquility is one of the important parameter in the mooring basin of harbor. It relates keenly to berthing/unberthing and cargo handling works but also it is an important indicator to get the minimum water area as the safe refuge. Hupo harbor is a national coastal harbor located in east coast of Korea and a development plan for a new marina near the entrance is being carried out including berth layouts, breakwater extensions, 300m marina berths, dredging and land reclamation works. The new plan will impact on calmness of the existing port. Therefore, it is necessary to analyze in complex the variation of wave height and direction caused by wave refraction, diffraction, shoaling and reflection from the incident waves from outside the harbor. In order to check the calmness inside a harbor, the numerical models are being used currently need fundamental reviews according to the difference of results which depend on their respective features. In this study, hence, it was introduced the validity of numerical models by comparing the computational results with the hydraulic model experiment. The current investigations contribute to the existing development recommendations and provide further solutions for port planning.

Emissions from aircraft have impacts on the air pollution of airport and the surrounding area. There are methods of emissions calculated as Tier 1, Tier2, Tier 3A and Tier 3B. Thus, this study investigated emissions from aircraft at the Gimhae International Airport using EDMS(Emissions & Dispersion Modeling System) program. Results of estimation from aviation emissions, Tier 3B considering all parts which can occur at the airport has the largest amount emissions. In order to understand the relation between aviation emissions and distribution of ozone concentration over airport area, numerical evaluation were carried out. Although the difference of surface ozone distribution between numerical assessment with and without aviation emissions was little, effects of air pollution at airport area from aviation emissions of NOx and VOCs.

This study probed into some characteristics of the urban household such as household income, number of the household, age distribution of the family members, their characteristics of shopping behavior such as the shopping place, types of the packaging and the characteristics of the time series, using consumer panel data of the Rural Development Administration (RDA). It further examined how the above factors affect fruit purchasing prices and then estimates the degree of the influence by each factor. The study looked at the purchase of apples, pears, tangerines, and oranges - the most favorite fruits in Korea. The results of this study can be utilized as the basic information for marketing strategies and/or for the establishment of future policy plans related to fruits consumption.

˜e onset, retreat, and precipitation of the Korean summer rainy season (Changma) signiÿcantly a˛ect human health and daily lives as well as domestic industry and economy. To increase revenue during Changma period, retail industry has tried to develop various weather marketing strategies on a regional basis. This study investigated the impact of Changma on the retail sales in Jeju. During Changma in Jeju in 2014, the temperature has dropped by 2.3°C, from 26.2°C to 23.9°C while the precipitation has significantly increased from 115.3mm to 441.5mm compared to last year. Due to these weather characteristics of Changma, large retailers in Seogwipo city have seen a high increase in sales of umbrellas, raincoats, and rain boots by 250-400 percent, but a decrease in sales of air conditioners by 15 percent. This results from more frequent rainfall and cool weather compared to the previous year. However, opposite results were found regarding traditional markets in Jeju. Depending on industrial structures in each region, the identical weather phenomenon have different impacts on the number of visitors to the markets. In other words, the impact of Changma on local retail sales is in˝uenced by multiple local factors including demographic composition and industrial structure in the regional economy.

In this study, Non-linear dynamic analysis of reinforced concrete bridge column in impact loading were performed using LS-Dyna.

Tensile stress and strain of rear by shock wave become the cause of rear side scabbing of concrete subjected to high-velocity impact. Improvement of flexural and tensile performance by fiber reinforcement has great effect on the suppression of the rear scabbing.

In this study, local fracture of concrete was evaluated through high-velocity impact test. As results, increase of bending tension performance by fiber reinforcement did not affect penetration depth Control, but it decreased rear side fracture thickness and diameter. Therefore, it was observed that fiber reinforcement decreases scabbing limit thickness.

In this study, impact of high-velocity projectile by mixing steel fiber, polyamide, nylon, polyethylene fiber which have different shape and properties respectively. Scabbing is restrained because of micro-crack caused by the shock wave offset effect and energy dispersive of synthetic fibers are mixed populations.

The purpose of this study is to establish a mathematical equation to evaluate the compressive strength of concrete from the measured impact resonance test values(Ed). The correlation was made between the measured and evaluated compressive strength values and the correlation was quite strong.

According to recent meterological disasters, social awareness for safety of infrastructure is heightened by increasing natural disasters such as Fukushima accident, landslide of Umyeon mountain. Also scale of landslide is increased in Korea but safety review of dam is insufficient. In this study, we reviewed data(reservoir capacity, type of dam, danger map of korea forest service, satellite pictures, geologic map, etc.) and conducted site investigation whose the area is the most dangerous. Based on the results, we choose the most dangerous dam and analysis site close examination, slope stability analysis, scale of debris flow, etc. As a result, we will conduct measures establish on reinforcement and final evaluation of landslide's hazard.

Purpose - This study was conducted to identify the impact of teachers’ professional development on students’ performance. It examines the nature of association between teachers’ professional development and students’ performance, and analyzes how students can be affected by different factors of teachers’ professional development. Research design, data, and methodology - In order to obtain the required goals, Data were randomly collected from 100 students and 45 teachers from three different institutes that are affiliated with KPK Agriculture University, Peshawar. To test the association between teachers’ professional development and students’ performance, the Chi-square test was applied. Gamma measurement was computed to check the direction of association. Results - The results of the study supported the statement that there exists a positive relationship between teachers’ professional development and students’ performance. Conclusion - Based on the findings it is surmised that, in order to create a clear learning relationship between teachers and students, management must support the teachers through peer group discussions and training opportunities, and should chooseteachers who can make students pursue the learning of subject knowledge with practical implementation

The paper deals with the impact of the product distribution and information technology sectors on energy resource use, carbon emissions and economic growth by examining the long-run equilibrium relationships and Granger causal relationships among these variables in South Korea. The quarterly time series data from the first quarter of 1970 to the third quarter of 2010 (163 observations) are collected and retrieved from the Bank of Korea database. The paper examines the long-run equilibrium relationships using cointegration techniques and Granger causality using vector error correction models. Test results indicate a long-run equilibrium relationship exists among these variables. In testing directional causality, both the product distribution and the information technology sectors show direct effects on economic growth but only marginal effects on carbon emissions.
