We utilized terahertz time-domain spectroscopy (THz-TDS) to measure the thickness and electrical properties of nickel-chromium (Ni-Cr) films. This technique not only aligns well with traditional methods, such as haze-meter and transmission-densitometer measurements, but it also reveals the electrical properties and thickness of films down to a few tens of nanometers. The complex conductivity of the Ni-Cr thin films was extracted using the Tinkham formula. The experimental values closely aligned with the Drude model, indicating the reliability of our Ni-Cr film's electrical and optical constants. The thickness of Ni-Cr was estimated using the complex conductivity. These findings emphasize the potential of THz-TDS in quality control of metallic nanofilms, pointing toward an efficient and nondestructive test (NDT) for such analyses.

김해 대성동 2호분 출토 판갑은 보존처리 과정에서 경판(經板)이 확인되고 오리문양 철판이 발견되는 등의 주목할만한 특징이 관찰되었다. 향후 동종(同種)의 판갑 보존처리과정에서 각별한 유물상태조사가 요구되는 부분이기도 하다. 또한 판갑의 복원에 있어서도 복원 재료의 내구성과 고증된 제작기법의 적용이 신중히 고려되었다.

This study explored measures to reduce noise applicable to Gimhae international airport centering on densely packed housing areas. Especially, as for measures to relieve noise damage on the densely packed housing areas in Gimhae-si, the noise reduction effect is expected to be doubled if the west runway (36L/18R) is used as the preferred runway for the 36 direction takeoff, as well as if the flight bypasses the densely packed housing areas by means of sophisticated navigation using the area navigation (RNAV) procedure based on performance-based navigation (PBN). Takeoff toward the south connects the flight path to the South Sea which has comparatively low noise impact, relieving noise damage on the densely packed housing areas (apartment complexes in Naeoe-dong of Gimhae-si, etc.) near the northern end of the runway. The operation of the runway displaced threshold is currently being implemented on the west runway (36L/18R) of Gimhae international airport. It has been found that swing landing in spring and summer when the wind blows from the south has a noise reduction effect on the noise sensitive areas at the side and end of the west runway (Gangdong-dong and Jukdong-dong of Gangseo-gu and Buram-dong of Gimhae-si, etc.).

Objectives: The study sought to identify the perception of schoolchildren's parents concerning an approval on the expansion implementation of community water fluoridation program in Gimhae, Korea. Methods: Questionnaires were distributed to schoolchildren's parents in Gimhae in 2008. Responses were collected from 1,703 parents. The standard questionnaire of Ministry of Health and Welfare was used and items were socioeconomic variables, water used for drinking and cooking, awareness on the fluoridation program and approval on the expansion implementation of fluoridation program at the region of Myeongdong water plant. Significance was analyzed by chi-square test and multiple logistic analysis. Results: Of parents, 1.9% used plain tap water and 39.8% used boiled tap water for drinking and 50.0% used tap water for cooking. 58.0% of parents were aware of fluoridation program with 27.1% being aware of the implementation of the program in Gimhae. 74.5% approved the expansion implementation of the program to the region of Myeong-dong water plant. Significant variables associated to approving the expansion implementation of program were age, gender, residence period in Gimhae, occupation and awareness of the program. Conclusion: The expansion implementation of fluoridation program in Gimhae is desirable for caries prevention because of the majority of schoolchildren's parents' approval.

한국의 공항 중 이용객 수 기준으로 4위 공항인 김해 국제공항은 국제선 이용객수가 점차 증가하고 있다. 이에 따라 동남권 신공항에 대한 필요성이 제기되었고, 국토교통부는 현재 김해 국제공항에 새로운 활주로 1본을 건설하여 확장하기로 결정하였다. 따라서 이로 인해 야기되는 소음을 예측하기 위해 본 연구에서는 FAA (Federal Aviation Administration)의 AEDT (aviation environmental design tool) 소프트웨어를 이용하여 소음 분석을 수행하였다. 본 논문에서는 김해 국제 공항에 신 활주로 건설 시 하루 동안의 항공기 이착륙 자료를 이용하여 현재보다 증가하는 소음 피해지역을 예측하였다.

This study aims to find the characteristics of damage and states of natural disasters at Gimhae, Gyeongsangnam-do from 1985 to 2004. Using the data of Statistical yearbook of calamities issued by the National Emergency Management Agency and Annual Climatological Report issued by the Korea Meteorological Administration. we have analyzed the cause, elements, and vulnerable regions for natural disasters. Major causes of natural disaster at Gimhae are four, such as a heavy rain, heavy rain typhoon, typhoon, storm snow, and storm. The cause of disaster recorded the most amount of damage is typhoon. The areas of Hallim-myeon, Sangdong-myeon, and Saengnim-myeon are classified the vulnerable region for the natural disasters in Gimhae. Therefore, it seems necessary to build natural disaster mitigation plan each cause of disaster to control water resources and to reduce damage for these areas.

The regional rainfall intensity formula for Gimhae in Gyeongsangnam-do province is developed in this study. The nine points of rainfall observations were selected. In order to demonstrate the accuracy and the versatility of the proposed rainfall intensity formula, three regions under the jurisdiction of the Meteorological Agency near Gimhae, namely Busan, Changwon, Miryang observatories were selected. The present formula can be effectively employed for various design of hydraulic structures in Gimhae area since it is divided into several refined regions.

최근 도시철도 노인 무임승차제도에 대한 논란이 거세지고 있다. 이에 본 연구는 부산김해경전철의 운영적자를 재정지원 하고 있는 부산시와 김해시 소속 공무원들을 대상으로 노인무임승차제도에 관한 10년간의 의식변화를 비교·분석하였다. 부산김해경전철은 국내에서 유일하게 노인무임승차제도를 실시하지 않는 도시철도이다. 2011년 9월과 2021년 4월, 노인 무임승차제도에 대한 이해와 지식이 상대적으로 높은 지자체 공무원들의 의식 조사를 실시하여 그 변화 과정을 추적하고 행정적, 정책적 고찰을 수행하였다는 점에서 차별성을 지닌다. 분석 결과를 요약하면, 부산김해경전철 개통 전후 의식변화가 확실히 나타났으며, 개통 이후 시간이 지남에 따라 찬성과 반대가 거의 동일한 비율로 수렴하는 것으로 나타났다. 특히 개통 전에는 교통관련부서 근무경험이 없는 응답자일수록 찬성 비율이 높았으나 시간이 지날수록 근무경험이 없는 그룹도 찬성 비율이 차츰 낮아졌다. 또한 시간이 지날수록 노인 무임승차제도의 지속보다는 정책대안 모색의 필요성이 강조되었다.
