In the Yeongdong region of Gangwon-do, coastal areas are important resources in terms of cultural, social and economic aspects. However, the coast of Gangwon-do is experiencing severe erosion, and it is concerned that its adverse effects will gradually increase. In this study, coastline changes of Yangyang and Gangneung in Gangwon-do were tracked and analyzed over a long period of time. In order to build time series image data, aerial photos from the 1940s to the present were mainly used, and data from CORONA satellite, which operated from the 1960s to the early 1970s, were collected and used together. Using 51cm resolution ortho image and 2m resolution Digital Elevation Model(DEM) as reference, ground control points were selected to perform geometric correction on the aerial photos and CORONA images. Subsequently, Canny edge detector applied to these images to extract the coastlines. As a result of analyzing the extracted and vectorized coastlines by overlaying them in chronological order, erosion and deposition occurring around the artificial structures and on the nearby beaches were observed. In this study, the effect of seasonal variation, tide, and various coastal management including the beach filling were not considered. Because coastal erosion is greatly affected by geographic factors, each local government must find its own solution. Continuous research and local data accumulation are required.

This study aims to provide basic data on socioeconomic and social activities from the point of view that disability or disease accompanying the suffering of industrial accident subjects is directly related to individual socioeconomic activity and is a major variable affecting current health and daily life satisfaction. The purpose of this study is to investigate the relationship between pain and life satisfaction and to suggest basic data for economic and psychological rehabilitation of industrial accident insurance beneficiaries by linking factors affecting life satisfaction with industrial accident services. As a result of the study, it was found that workers' compensation insurance benefit recipients had an effect on their daily life satisfaction after becoming an industrial accident patient due to industrial accident pain. There was a positive(+) relationship between rehabilitation services and medical counseling services. Occupational accident pain lowers self-esteem, which is a characteristic of an individual, and even if current health improves, satisfaction with daily life decreases. The importance of industrial accident-related services can be seen in that the satisfaction of daily life is increased through rehabilitation services and medical consultation services. In addition, it was indirectly confirmed that satisfaction with rehabilitation services and health can be improved as a result of continuing attempts to improve self-esteem suitable for patients in various problems and situations after an industrial accident.

It is reported that social distancing caused by the corona pandemic has resulted in a decrease in physical activity, and a decrease in muscle mass due to this increases the risk of vascular disease. Therefore, in this study, the risk of carotid intima media thickness was evaluated by measuring the thickness of CIMT, and the differences in variables according to gender were analyzed. From January 2022 to May 2022, a total of 220 people (121 males, 99 females) who performed blood tests, carotid ultrasound, and body composition analysis among those who visited the health check-up center of Busan H Hospital were included in this study. Significant differences in risk factors according to gender were analyzed using the chi-square test. The cut-off values of variables that can predict the risk of carotid intima media thickness were calculated, and the accuracy was evaluated by calculating the area under the curve, sensitivity, and specificity. As a result of the difference analysis, the higher the total cholesterol in men and the appendicular skeletal muscle index in women, the higher the risk of carotid intima media thickness. The cut-off value for predicting the risk of carotid intima media thickness was calculated to be greater than 199 mg/dL of total cholesterol in the male group and less than 5.9 kg/m² of the appendicular skeletal muscle index in the female group. As a result of this study, the higher the total cholesterol in men and the lower the appendicular skeletal muscle index in women, the higher the risk of increased CIMT. Therefore, in women, the appendicular skeletal muscle index is expected to serve as an indicator to predict and prevent vascular changes at an early stage.

Total knee arthroplasty is performed widely in degenerative arthritis of the knee joint, and the frequency of use is increasing. Efforts should be made to achieve functional recovery, such as returning to daily life, and the recovery of strength and range of motion after surgery. The procedure should be approached from a range of perspectives, such as patient factors, surgical technique and rehabilitation. The patient's age, degree of obesity, sex, and strength of the quadriceps muscle can affect the functional recovery after surgery. In addition, the patient's mental state, such as expectation value and satisfaction, can also have an effect. For functional recovery, patient education, pain control, and strengthening of the quadriceps muscle can be performed prior to surgery. Postoperative physiotherapy, such as icing and compression, transcutaneous electrical nerve stimulation therapy, neuromuscular electrical stimulation therapy, low frequency low intensity magnetic field therapy, strengthening of quadriceps muscle, and range of motion exercise can also be applied. In recent years, hydrotherapy, which restores the strength and balance of the leg, is being performed increasingly. These treatments are not only performed shortly after surgery, but are also performed continuously. In addition, the surgeon should apply it appropriately considering the patient's condition, compliance, and social and psychological conditions.

Recently, the recommender system has been widely used in various fields such as movies, music, online shopping, and social media, and in the meantime, the recommender model has been developed from correlation analysis through the Apriori model, which can be said to be the first-generation model in the recommender system field. In 2005, many models have been proposed, including deep learning-based models, which are receiving a lot of attention within the recommender model. The recommender model can be classified into a collaborative filtering method, a content-based method, and a hybrid method that uses these two methods integrally. However, these basic methods are gradually losing their status as methodologies in the field as they fail to adapt to internal and external changing factors such as the rapidly changing user-item interaction and the development of big data. On the other hand, the importance of deep learning methodologies in recommender systems is increasing because of its advantages such as nonlinear transformation, representation learning, sequence modeling, and flexibility. In this paper, among deep learning methodologies, RNN, CNN, and GAN-based models suitable for sequential modeling that can accurately and flexibly analyze user-item interactions are classified, compared, and analyzed.

This study attempted to find a Christian religious alternative to the seriousness of the problem of low birth rate which has become a national and social problem, and its alternative. Korea is a low birth rate country. The phenomenon of low birth rate and childbirth avoidance is a reality that not only are national problems but also Korean churches are experiencing serious problems, and will continue to affect them. It will affect the church in four major ways. First, is a sharp decline in the number of members. Second, is the decline of Sunday schools. Third, various family problems and generational conflicts will arise. And it brings problems such as a crisis of faith among members. Young people living today have an unconventional attitude toward marriage, childbirth, and parenting. But for Christians, childbirth is a way of living in that God blessed us to "be fruitful, multiply, and fill the earth." In other words, childbirth must be recognized as a blessing from God, not a human decision. Therefore, we must know how precious the fetus is in front of God and that it is a precious life. Thus, we should be interested in how to nurture the life God has given. To do so the church's role is education is to shape the value of life from a biblical perspective. Therefore the church needs to see how the Christian faith of young and married couples who are about to marry, give birth, and raise children, affects the childbirth and rearing of children. And it is necessary to study what the role of church and Christian education is to solve the problem of low birth rate and to suggest alternatives. For this study, we will first identify the factors of low birth rate. Then we will confirm childbirth and the blessing of God through the Bible. Finally, the role of the church in low birth rate and educational alternatives will be presented.
