승선 환경의 폐쇄성과 이사회성, 선내 규율의 엄격함 등으로 청년들은 선원직을 기피하고 있다. 우리나라는 승선근무예비역제도라는 특수한 제도가 존재해 청년들을 선원직으로 유인하고 있지만, 이 제도마저 존립이 위태롭다. 최근의 선원 고용유형은 선박관리회사로부터 고용되어 선사에 파견되는 비정규직 형태가 대부분이다. 선박관리회사(SM)와 선원 간에 임시 고용계약을 맺고, SM이 선사에 선원을 파견하는 비정규직 고용형태가 유행하고 있다. 선원직 매력도가 떨어지고 있는 상황에도 2018년 발표된 국가 해운재건 5개년 계획에는 선박과 화물의 확보 방안만 담겨 있다. 이 논문의 핵심 내용은 이항로짓모형을 이용해 선원의 고용형태 결정요인을 분석하는 것이다. 분석 결과, 선원의 최종학력이 고용형태를 결정하는 요소로 나타난 반면, 소속선사 유형, 승선 선종, 소속 선박관리회사 유형, 근무 분야, 해기사 면허 소지 여부 등은 선원 고용형태 결정에 유의미한 변수가 아닌 것으로 나타났다.

It is well known that high school girls' mean achievement levels in science tests are lower than high school boys' and that fewer women than men are employed as scientists and engineers pursue scientific careers. Many research attributed the sex difference in achievement level in science and the lack of women in science among others, to the experiential differences in scientific activities and the differences in attitudes toward science and scientists. Therefore, the study had its object to examine the sex difference by high school students in scientific experience and attitudes toward science and scientists. The differences in science experiences were identified at eight schools over rural and urban areas in Kangwon province. Science activities surveyed included use of experimental materials and instruments, observation of scientific phenomena, and extracurricular scientific activities. Attitude scale contained the nature of science, scientific research methods and philosophical views held by scientists. The study found sex differences in scientific experiences and attitudes. i. e.: fewer high school girls than boys had experience with scientific activities, especially with extracurricular activities; however, girls had more positive attitude toward science and more active desire to participate in science. Consequently, the study implies that, in order to narrow the gaps between achievement levels for boys and girls, science education should take consideration of the sex difference in experiences with and attitudes toward science.

This article presents program development and analysis of a creative robot school for elementary school at the local university. The purpose of opening the creative robot school is to give motivation to children for having interests in science and engineering at their young ages. The creative robot school program is developed by using facilities of a local university to spread scientific knowledge to young children in their communities to draw their interests in science as well as an engineering field for future careers. Since the robot system is a popular subject to draw attention of children and has a relation with Mechatronics Engineering, a program related with robots is selected for educating children. College students are also involved in helping children to build robots within a given time. Experiences and self-evaluations from the previously held creative robot schools at Chungnam National University(CNU) are presented to share with.

Dietitians' satisfaction between elementary school and high school in KangWon Do region were surveys with questionnaires. 61 elementary school dietitians and 30 high school dietitians participated. The dietitians in elementary schools had higher scores in age, marital status, years at work, types of employment, average annual income and had lesser hours of work. In overall, elementary schools had higher percentage on self operation and on the period of their food distribution to students. High schools had higher percentage on conventional systems, freedom in the amount of food distribution, number of meals per day and the meal charge. It was clear that dietitians in high schools showed more interests in changing their careers due to the poor working environment and salary. The highest score was on the relationship with other coworkers and the lowest score was on the poor working environment and salary. In general, dietitians in both types of schools are not satisfied with their career, especially with the working environment and salary.

E-learning is a new teaching model nowadays, and Virtual Reality (VR) technology is reported that the use of virtual reality as an education tool can increase student interests, understanding, and creative learning because of encouraging students to learn by exploring and interacting with the information on the virtual environment. Besides that, LEGOs have long been the favorite of many children. LEGOs provide a mechanism to understand and do for many concepts from spatial relationships to robotics platforms. In this paper, we present a virtual reality application based on the assembly of LEGO-Like bricks to increase math and science learning by improving spatial thinking. It not only encourages students to pursue careers in science, technology, engineering, or mathematics but also enhances learner's ability to analyze and solve problems. The application is built by Processing 2.0 as the easier programming language which is a top-down approach to build the 3D interactive program.
