Pig slurry (PS) is the most applicable recycling option as an alternative organic fertilizer. The application of pig slurry has the risk of air pollution via atmospheric ammonia (NH3) and nitrous oxide (N2O) emission. The zeolite has a porous structure that can accommodate a wide variety of cations, thus utilizing for the potential additive of deodorization and gas adsorption. This study aimed to investigate the possible roles of zeolite in mitigating NH3 and N2O emission from the pig slurry applied to the maize cropping. The experiment was composed of three treatments: 1) non-N fertilized control, 2) pig slurry (PS) and 3) pig slurry mixed with natural zeolite (PZ). Both of NH3 and N2O emission from applied pig slurry highly increased by more than 3-fold compared to non-N fertilized control. The NH3 emission from the pig slurry was dominant during early 14 days after application and 20.1% of reduction by zeolite application was estimated in this period. Total NH3 emission through whole period of measurement was 0.31, 1.33, and 1.14 kg ha-1. Nitrous oxide emission in the plot applied with pig slurry was also reduced by zeolite treatment by 16.3%. Significant increases in forage and ear yield, as well as nutrient values were obtained by pig slurry application, while no significant effects of zeolite were observed. These results indicate that the application of zeolite and pig slurry efficiently reduces the emission of ammonia and nitrous oxide without negative effects on maize crop production.

Background: Incorrect postures of adolescents caused by the use of smart devices have been noted as a factor causing spinal diseases. Objectives: To examine the effect of joint mobilization and stretching on Cobb’s angle and respiratory function in adolescent idiopathic scoliosis (AIS). Design: Cluster-randomized controlled trial. Methods: A total of 22 subjects with AIS were enrolled. They were allocated to two groups: the joint mobilization (n=11) and the stretching (n=11). All interventions were conducted for 30 minutes, three times a week for six weeks. Outcome measures were the Cobb’s angle and respiratory function. The Cobb’s angle and respiratory function measured using the X-ray and Micro- Quark. Results: Joint mobilization group showed significant differences in Cobb’s angle and respiratory function, but stretching group showed significant differences Cobb’s angle. The differences in peak expiratory flow (PEF) between the two groups were significant. Conclusion: This study proved that joint mobilization is a more effective intervention for AIS to improve Cobb’s angle and respiratory function, when compared to stretching.

Since the first detection of the African swine fever (ASF) virus in the Republic of Korea in 2019, the Korean government has applied interventions, including fencing, increasing the biosecurity level at domestic pig farms, and the capture-and-removal of wild boars. In particular, wild boars are an important risk factor for ASF control because they can spread disease among susceptible animals, such as wild boars or domestic pigs. A capture-and-removal method aims to reduce the likelihood of ASF transmission from wild boars to domestic boars or among wild boars by decreasing the number of susceptible wild boars. This study estimated the required number of wild boars captured and removed for ASF control using population viability analysis. Population factors, such as a life span, sex ratio, or an inbreeding depression with different capture-and-removal proportions of wild boars, were included in the analysis. Ten scenarios with different capture-and-removal proportions of wild boars and different periods of culling were considered. According to the results, a method in which 75% of wild boars are captured-and-removed for at least three years showed long-term effectiveness for more than ten years. The current ASF control method, in which 33% of wild boars are captured-and-removed, decreased the number of wild boars for three years, after which the wild boar population increased to more than its initial number. Given the limited human and material resources for controlling ASF in the Republic of Korea, it is recommended that resources be prioritized to increase the capture-and-removal proportion of wild boars to take full advantage of the ASF-control effectiveness.

Recently there was an incident that military radars, coastal CCTVs and other surveillance equipment captured a small rubber boat smuggling a group of illegal immigrants into South Korea, but guards on duty failed to notice it until after they reached the shore and fled. After that, the detection of such vessels before it reach to the Korean shore has emerged as an important issue to be solved. In the fields of marine navigation, Automatic Identification System (AIS) is widely equipped in vessels, and the vessels incessantly transmits its position information. In this paper, we propose a method of automatically identifying abnormally behaving vessels with AIS using convolutional autoencoder (CAE). Vessel anomaly detection can be referred to as the process of detecting its trajectory that significantly deviated from the majority of the trajectories. In this method, the normal vessel trajectory is gridded as an image, and CAE are trained with images from historical normal vessel trajectories to reconstruct the input image. Features of normal trajectories are captured into weights in CAE. As a result, images of the trajectories of abnormal behaving vessels are poorly reconstructed and end up with large reconstruction errors. We show how correctly the model detects simulated abnormal trajectories shifted a few pixel from normal trajectories. Since the proposed model identifies abnormally behaving ships using actual AIS data, it is expected to contribute to the strengthening of security level when it is applied to various maritime surveillance systems.

The long term objective should be to achieve a high degree of self-financing for the WEU. However, initial funding of at least US$5 million will be needed to develop the University through the launching of its initial programs. This will have to come primarily from Korean sources. Korea will need to take a lead in mobilizing the funds required for the ongoing operation of the University until the WEU has progressed to the point where it can command attention and support of international funding sources and significant fee income. The process to establish the University will be initiated as soon as the final decision of the Government of South Korea is confirmed.

본 논문에서는 영화에서 인물의 극적인 등장, 등장 인물 간의 관계를 효과적으로 표현하 고자 할 때 주로 사용하는 영화 촬영 기법 ‘아크 트래킹 샷’을 비주얼 노블 게임에 카메라 연출을 설계 및 구현하여 적용하였다. 비주얼 노블은 소설을 읽듯 이야기 진행에 중 점을 둔 게임의 한 장르로 이미지, 사운드 등 시청각적 요소를 첨가하여 이야기의 몰입을 돕는다. 그러나 기존 비주얼 노블의 카메라는 정적이며 움직임이 극히 제한되어 있어 플레이어의 이야기 몰입도를 높이기에는 어려움이 있다. 이를 극복하고자 이야기의 전달이 중요하다는 공통점을 가진 영화의 촬영 기법 아크 트래킹 샷을 3D 게임 엔진에 가상의 카메라 트래킹 레일을 만들고 카메라에 적용하는 과정을 통해 비주얼 노블의 카메라 연출에 적용하였다. 영화 연출 기법을 비주얼 노블 게임콘텐츠에 적용하면서 기존 비주 얼 노블 연출의 단점을 극복하고 역동적인 카메라 움직임은 플레이어에게 몰입을 유지 시키는 작용을 하며 제작자가 전달하고자 하는 감정과 의미를 더욱 효과적으로 전달할 수 있도록 구현하였다.

In order to satisfy customers, it is important to identify the quality elements that affect customers’ satisfaction. The Kano model has been widely used in identifying multi-dimensional quality attributes in this purpose. However, the model suffers from various shortcomings and limitations, especially those related to survey practices such as the data amount, reply attitude and cost. In this research, a model based on the text sentiment analysis is proposed, which aims to substitute the survey-based data gathering process of Kano models with sentiment analysis. In this model, from the set of opinion text, quality elements for the research are extracted using the morpheme analysis. The opinions’ polarity attributes are evaluated using text sentiment analysis, and those polarity text items are transformed into equivalent Kano survey questions. Replies for the transformed survey questions are generated based on the total score of the original data. Then, the question-reply set is analyzed using both the original Kano evaluation method and the satisfaction index method. The proposed research model has been tested using a large amount of data of public IT service project evaluations. The result shows that it can replace the existing practice and it promises advantages in terms of quality and cost of data gathering. The authors hope that the proposed model of this research may serve as a new quality analysis model for a wide range of areas.
