The purpose of this study is to identify the effect of seasonality on the tourism and hospitality industry in ArugamBay after the civil unrest across the different firms in tourism. This study uses both quantitative and qualitative analyses using primary data. Fifty questionnaires give valid responses that were used for analysis. Out of 80 questionnaires, the average response rate was 62.5%. An exploratory study, descriptive analysis, and an Independent Sample Test were used to identify the potentials of tourism, the overall impact of seasonality, and the impact of seasonality across different travel and tourism sector of the study area. According to the results, 83%, 75%, 68%, and 59.9% of firms agreed on the impact of seasonality on environment, workers, supply, and quality of services, respectively in ArugamBay. It also concluded that the impact of seasonality on workers, supply, and quality of services is not the same among all the categories of firms except environment. The variation in seasonality in the travel and tourism sector is because of the lack of regional planning considering the types of firms in the tourism sector. Also, insufficient resources and lack of consistent capacity between various firms in the sectors are also course variations because of the effect of seasonality.

도서관 여행 프로그램은 J시가 처음 도입, 운영하고 있는 새로운 형태의 문화프로그램으로, 도서관 여행자는 정해진 코스에 따라 관내 특화 도서관을 여행하며 다양한 체험을 하게 된다. 본 연구는 보다 많은 이용자들이 도서관 여행에 참여할 기회를 누릴 수 있도록 기존 고정된 단체여행 형태 외에 개별 참여하는 이용자의 특성을 고려한 맞춤형 코스 추천 모델 구축을 목적으로 한다. 이를 위해 도서관 여행자의 특성을 유형화하여 여행자 페르소나를 설정하였으며, 그에 따른 도서관 평가 항목과 평가 기준을 수립하였다. 도서관 여행 프로그램의 대상이 되는 도서관 22관을 선정, 실제 답사를 통해 도서관 데이터를 실측하였다. 수집한 데이터를 기반으로 여행자의 특성에 적합한 도서관의 특징을 도출하였으며, 의사결정나무 알고리즘을 활용해 페르소나 기반의 도서관 여행 코스 추천 모델을 개발하였다. 나아가 추천 모델의 활용 가능성을 시연하기 위해 이를 적용한 모바일 앱 목업을 제작하였으며, 실제 J시 도서관 이용자들을 대상으로 사용자 평가를 진행해 개발한 모델의 만족도와 개선사항을 파악하였다.

This paper used the golf course visitors' data in Jeju region to forecast the growth of inbound air traveler to Jeju. This is because the golf course visitors were proven to bring the highest economic and production inducement effect to the Jeju region. Based on such a data, this paper forecast the short-term growth rate of inbound air traveler using ARIMA to the Jeju until December 2025. According to ARIMA (0,1,0) (0,1,1) model, it was analyzed that the monthly number of golf course visitors to Jeju has been increasing steadily even since COVID-19 pandemic and the number is expected to grow until the end of 2025. Applying the same parameters of ARIMA (0,1,0) (0,1,1) to inbound air travel data, it was found the growth rate of inbound air travelers would be higher than the growth rate of 2019 shortly without moderate variation even though the monthly number of inbound travelers to Jeju had been dropped during COVID-19 pandemic.

This paper presents a novel approach based on the loci of instantaneous symmetrical components called "Wing Shape" which requires the measurement of three input stator currents and voltages to diagnose interturn insulation faults in three phase induction motors operating under different loading conditions. In this methodology, the effect of unbalanced supply conditions, constructional imbalances and measurement errors are also investigated. The sizes of the wings determine the loading on the motor and the travel of the wings while their areas determine the degree of severity of the faults. This approach is also applied to detect open circuit faults or single phasing conditions in induction motors. In order to validate this method, experimental results are presented for a 5 hp squirrel cage induction motor. The proposed technique helps improve the reliability, efficiency, and safety of the motor system and industrial plant. It also allows maintenance to be performed in a more efficient manner, since the course of action can be determined based on the type and severity of the fault.

As the quality and level of life rise, many people are doing search for various pieces of information about tourism. In addition, users prefer the search methods reflecting individual opinions such as SNS and blogs to the official websites of tourist destination. Many of previous studies focused on a recommendation system for tourist courses based on the GPS information and past travel records of users, but such a system was not capable of recommending the latest tourist trends. This study thus set out to collect and analyze the latest SNS data to recommend tourist destination of high interest among users. It also aimed to propose an altered TSP algorithm to recommend the optimal routes to the recommended destination within an area and a system to recommend the optimal tourist courses by applying the Elasticsearch engine. The altered TSP algorithm proposed in the study used the location information of users instead of Dijkstra's algorithm technique used in previous studies to select a certain tourist destination and allowed users to check the recommended courses for the entire tourist destination within an area, thus offering more diverse tourist destination recommendations than previous studies.

The National Research Institute of Cultural Heritage(NRICH) conducted the Asia Cooperation Programme in Conservation Science(ACPCS) to facilitate and promote the regional cooperation in the conservation of cultural heritage among Asian countries. This course was promoted to provide an opportunity to study and work together, also to share a knowledge and experience in conservation field. The target countries were from 17 Asian countries, and this year our selection committee selected 2 specialist in cultural heritage conservation field and selected persons had participated in the ACPCS course during three months. NRICH provided the round-trip airline tickets, overseas travel accident insurance and a living allowance to the course participants. And we requested programme announcement to Korean National Commission for UNESCO and Ministry of Foreign Affairs and Trade to progress favorably. This course period was three months from 29 August to 25 November, and the fields were conservation and restoration of tangible cultural heritage such as metal conservation, stone conservation, material analysis, DNA analysis, dating, biological control management of cultural heritage, environmental monitoring and so on.

LTV(Light Tactical Vehicle) operating in our military requires higher levels of performance and durability to withstand harsher conditions than general vehicles, as they must travel on both rough-train and off-road as well as on public roads. Recently, LTV development is demanded a variety of test evaluations in order to satisfy ROC (Required Operational Capability) by the military requirement. However, there is no informations of driving test course for satisfying the durability performance of Korean tactical vehicle. Therefore, this study aims to provide basic data to establish reliable drive test conditions by analyzing the main maneuvering test site at the domestic and foreign country in order to select the representative drive course. These studies will provide a more scientific and systematic evaluation solution for the development of tactical vehicles, and can be effectively used to establish a certified system for military vehicle test evaluation in the future

컨테이너 터미널의 자동화는 항만 경쟁력을 좌우하는 중요한 요소로 글로벌 선진항만은 컨테이너 터미널 자동화를 통해 경쟁력을 강화하는 추세이다. 자동화 터미널의 필수 이송 장비인 AGV의 운영 효율화는 자동화 터미널의 생산성을 제고할 수 있다. 자동화 컨테이너 터미널에서의 AGV 운영은 기존 컨테이너 터미널의 이송 장비 운영과는 다르게, 지정된 경로에 따라 주행하는 등 자동화 시스템을 기반으로 운영되어 작업부하 및 교착, 충돌 등과 같은 문제들을 고려하여야 한다. 이러한 요소들을 방지하고 AGV 운영 효율화를 지향하기 위해서는 보다 정교한 모델이 필요하다. 따라서, 본 논문에서는 터미널 내 AGV 주행경로 및 작업 배정 상황을 고려한 AGV 스케줄링 모형을 제안한다. 해당 모형은 교착 상황에 대한 문제를 예방하고 AGV 대수 및 작업 개수 변경으로 다양한 Case를 생성해 AGV 주행상황을 만들어 알고리즘과 최적해 분석을 통해 제안한 알고리즘을 평가한다.
