To analyze the incident wave characteristics around Haeundae beach the long-term deep water wave data computed by wave hindcast method were used and a continuous wave observation was carried out for 1 year at the 20 m of water depth in front of Haeundae beach. Wave observation data showd that the prevalent wave direction was SSW-S in spring and summer seasons while E-SE in autumn and winter. A numerical modeling shows that the waves from E-SE are refracted strongly due to the shoal developed at the south-east side of Haeundae beach. The simulation also shows inflowing nearshore current along the east coast of the beach develops strongly in autumn and winter. Radioactive isotope tracer experiment for 155 days indicated that the tracers moves to the on-shore direction in the 1st and 2nd tracking then dispersed to the E-W direction along the shore.

The purpose of this study was to examine the correlation between academic achievement, major selection motivation, work value, and campus life adjustment of healthcare major college students. Data was collected using a structured questionnaire for 495 healthcare major college students at a four-year university located in G city. As a result of the study, Academic achievement was determined with positive correlation by major selection motivation (r=.446, p<.001), work values (r=.255, p<.001), campus life adjustment(r=.391, p<.001), Major selection motivation was positively correlated with work value (r=.354, p<.001) and campus life adjustment (r=.220, p<.001). The work value showed a positive correlation with the campus life adjustment(r=.193, p<.001). It is necessary to develop a career education program that reinforces college students' major selection motivation and their work values, and a student guidance program that improves their adaptation to college life.

An estimation of reliable probability precipitation is one of the most important processes for reasonable hydrologic structure design. A probability precipitation has been calculated by frequency analysis using annual maximum rainfall series on the each duration among the observed rainfall data. Annual maximum rainfall series have abstracted on hourly rainfall data or daily rainfall data. So, there is necessary to proper conversion factor between the fixed and sliding durations. Therefore, in this study, conversion factors on the each duration between fixed and sliding durations have calculated using minutely data compared to hourly and daily data of 37 stations observed by Meteorological Administration in Korea. Also, regression equations were computed by regression analysis of conversion factors on the each duration. Consequently, conversion factors were used basis data for calculations of stable probability precipitation.

This study analyzed the current status of the convergence departments of universities from 2019 to 2023. The number of installation increased from 430 in 2019 to 649 in 2023. The accumulated number of abolition increased from 177 to 509 at the same period. Many were suddenly installed without enough readiness. The convergence department bubble phenomenon began to extinguish in 2022. The number of the convergence departments in academic division was more in the order of engineering, humanities and social sciences, natural sciences, and arts and sports every year. The proportion of engineering decreased and that of humanities and social sciences increased. The number of sub-division installing convergence departments increased from 65 to 81 during 5 years. Convergence education was in the process of gradually spreading to various fields.

The purpose of this study is to investigate how engineering design-based STEM research experience affects gifted students' creative engineering problem-solving propensity and attitude toward engineering. The students' creative engineering problem-solving propensity and attitude toward engineering were measured before and after the STEM research experience. The pre-/post-tests results were analyzed by paired t-test with the significance level of p <.05. The conclusions of the study are as follows: First, the engineering design based STEM research experience had a positive effect on the students' creative engineering problem-solving propensity. Over all, the average score of the creative engineering problem-solving propensity increased significantly (p <.05) after the STEM research experience. Second, the average score of gifted-students' attitude toward engineering had increased significantly after the integrated STEM research activities (p <.05). In addition, we analyzed the difference between pre-post results of both instruments based on the gifted students' desired career paths (natural science and engineering) and gender. The result shows that the students' career paths or gender did not affect the results in most of the sub-categories in both instruments. However, the STEM research experience had more positive effect on the female students than male students in term of their 'engineering design ability', which is one of the sub-categories of the creative engineering problem-solving propensity instrument.

앞으로 10년 후에는 공대 졸업자는 더욱 부족해지고 인문사회계열 졸업자는 과잉 공급될 것으로 추산되면서 일자리 수급 불균형을 해결해야 한다는 목소리가 높아지고 있다. 계속 이렇게 이공계 전성시대가 계속될 것인가? 우리는 미래 사회가 필요로 하는 역량을 갖춘 공대 졸업생을 배출하고 있는가? 당사자인 공대를 졸업한 졸업생은 엔지니어로서 긍지와 자부심을 가지고 살고 있는가? 바로 지금이 이런 문제에 대한 반성적 논의가 필요한 때이다.

전기.정보계열의 학과에서는 기초 과목으로 전자기학, 회로이론, 양자역학, 통계역학, 수학 따위인데, 정보 관계에서는 전자기학보다도 소프트웨어공학에 도움이 되는 과목을 4년간 교육해야 한다. 4년간이라고 해도 실질적으로 2년 반이므로 대학의 4년간이라는 것은 상당히 큰 문제를 안고 있다. 대학원 진학이 늘어가는 추세에서 학부만 마친 학생도 있으므로, 이것에 대해서는 산업계의 필요성을 받아들이는 동시에 산학 공동 또는 산관학의 협력 체제를 갖추어야 한다. 따라서 산업계와 대학이 일체가 되어 대학의 교과과정을 토의하는 자리를 마련해 교육 시책에 반영하는 것이 필요하다. 상호가 협력하는 시스템, 산업계와 대학이 융합할 수 있는 프로그램을 학회를 중심으로 한 중립의 자리에서 만들 필요가 있다.

Physiological characteristics of brown rice and black rice were investigated to provide the fundamental information of physiological property of rice and to show the potential of rice as a functional ingredient. Bioactive compounds were extracted from brown and black rices with aqueous solvents like 80% ethanol. Total phenolics, flavonoids and antioxidative capacity of brown and black rices' extracts were determined. Brown rice showed much higher amount of total phenolics and flavonoid contents as well as antioxidative capacity than those of milled rice indicating that most of bioactive compounds are located in the bran layer. Black rice showed higher total phenolics and flavonoid contents and antioxidative capacity than those of brown rices. The highest antioxidative capacity was obtained from Heugjinju followed by Heugseol, Sinnongheug-chal, Hopum and Samkwang. This result indicated that antioxidative capacity is affected by total phenolics and flavonoid contents. Both brown and black rices contained higher amount of ferulic acid than that of p-coumaric acid.

This study explored the effect of job experience while attending engineering colleges on entry into the labor market. To this end, the relationship between work experience and first job success among the job preparation behaviors of engineering majors and students with other majors was compared. Next, we analyzed the effects of work experience such as internships experienced by engineering students on adjusting to their first job after graduation and maintaining their employment. In particular, by analyzing the relative influence of factors affecting engineering students' entry into the job market, what kind of policy efforts can be made at the university level for the success of engineering students' employment is presented. The results showed that work experience affects the quality of employment of engineering, and it had a positive effect on all engineering students regardless of gender.
