This study explored medical students' major research topics and research methods by analyzing 184 academic articles pertaining to the characteristics of medical students from 2007 to 2017. Results showed many papers dealing with medical students' emotional and cognitive aspects, student counseling, clinical practice education, and curriculum management. According to the medical education accreditation board, research trends were found mostly in the student and curriculum areas of learner characteristics, medical humanities, student counseling, clinical practice education, and curriculum management. Common research topics have been steadily increasing since the introduction of the evaluation accreditation standard in 2012. Medical students predominantly used quantitative research methods for the studies. In the future, it is necessary to ensure that research topics such as CQI, digital- and performance-based clinical practice, and convergent curriculum within the Fourth Industrial Revolution are being studied. In addition, it is crucial to investigate learners' unique, dynamic, and qualitative characteristics through qualitative and mixed methods.

The surveys of food intakes were carried out on 49 healthy infants aged 4-9 months at the first interview and repeated 3 more times at the interval of 2 months by using food diary recorded by their mothers. Of the subjects 12 were breast-fed, 28, formula-fed, and 9, mixed type-fed. Foods introduced first as the weaning food were commercial weaning foods, fruit juices, yoghurt, egg and rice. Supplemental food was introduced at the age of 4 months in 57% of the infants, but it amounted to a significant proportion of overall food consumption from the age of 6 months. The levels of nutrients except energy, iron and niacin were similar or in excess of RDA, and breast-fed infants tended to have lower intakes of energy and protein compared to infants formula-fed or mixed type-fed. Average intakes of vitamin A, vitamin B1, vitamin B2, vitamin C and calcium were above RDA, but iron intake did not meet RDA of infants of all ages. In conclusion, the average status of nutrient intakes of infants was fairly good, however, food consumption besides milk was less in breast-fed infants than in formula-fed infants, and iron status seemed to be poor, Although it is well-known that breast-milk compared to formulas is more beneficial for infants, mothers feeding breast-milk to their infants should be educated for the importance of supplemental food and its practice to support good nutrition.

In China, serious environmental problems are induced by the extremely soft construction waste slurries in many urban areas, and there is no appropriate method to treat it presently. In this paper, four model tests were conducted to investigate the efficiency of waste slurry treatment by combining three conditioning agents which can change characteristics of the slurries with a traditional vacuum preloading method. The tests of size analysis of particle aggregate were conducted to investigate the influence of different conditioning agents on the size distributions of particle aggregate. During the model test, the discharged water volumes were monitored. The pore-size distribution and void ratio of the waste slurries after the vacuum preloading were measured by mercury intrusion porosimetry (MIP). It is found that 1) During the natural precipitation, volume of water out of the organic agent is higher than that of the mixed agent, but it is smaller than that of the mixed agent in the vacuum preloading stage; 2) the mixed agent has a higher total volume of water out than the organic agent and the inorganic agent after test, while the organic agent and the inorganic agent have little difference with respect to the drainage effect. The results demonstrate that the combination of mixed conditioning agent and vacuum preloading for the solid-liquid separation in waste slurry has a satisfactory effect and can be applied in engineering practice.

This study was conducted to evaluate the ecological attributes of forest types which were classified by cluster analysis in the natural forest of Mt. Odae on the basis of the vegetation data (232 sampling points) from the point-quarter sampling methods. For the classified types, the species composition was expressed by importance value to describe the stand structure and the species diversity was quantified using the Shannon's diversity index. Recognized forest types were 1) Quercus mongolica-Pinus densiflora-Betula ermanii forest type, 2) Mixed mesophytic forest type, 3) Q. mongolica forest type, 4) B. ermanii forest type. Species diversity indices of total and overstory were highest in the Mixed mesophytic forest type (3.465 and 2.942), and lowest in the B. ermanii forest type (0.118 and 0.832). In addition to that, Q. mongolica-P. densiflora-B. ermanii forest type was calculated as 3.226 and 2.565, and Q. mongolica forest type was calculated as 2.776 and 1.218 in total and overstory, respectively. It was considered that after the P. densiflora and B. ermanii first invaded and site condition became good, Q. mongolica-P. densiflora-B. ermanii forest type was dominated by Q. mongolica. Mixed mesophytic forest type showed the most stable stand structure with various species distributed uniformly. Q. mongolica forest type would preserve the present stand status for a while, and the B. ermanii in B. ermanii forest type would be pressed by other species over time.

This study was carried out to investigate the future plan for infant feeding practice and its associated factors among university students so as to develop focus for nutritional education program for the promotion of breastfeeding. The subjects were 301 students (males 130, females 171). The results obtained were as follows. In this survey, the subjects had a basic knowledge of breastfeeding and lactation, especially of the ingredient of breastmilk. However they were not well informed about the physiology and method of breastfeeding and benefits of breastfeeding for mothers. The average scores far attitude toward breastfeeding and lactation were 3.09 points on a 4 point scale, which indicated a slightly positive attitudes toward breastfeeding. However the participants had a negative attitude toward its emotional and practical aspects. Their future plan for infant feeding was breastfeeding 40.3%, formula feeding 3.0% and mixed feeding 56.7%. A concern was that the students showed a high rate with regard to a mixed feeding plan, and Dey decided this based on an incorrect knowledge of breastfeeding. The group who planned to breastfeed in the future (BF) showed higher scores with respect to knowledge and attitudes than those who planned to formula feed or mixed feed (FF + MF). Therefore, to encourage mothers to breastfeed and support breastfeeding, breastfeeding nutritional education is urgently needed among university students. In addition, nutrition education programs should promote the benefits of breastfeeding for mothers and the physiology and practical method of breastfeeding. Also a practical and culturally sensitive course about food and nutrition is recommended to inform participants about breastfeeding. (Korean J Community Nutrition 8(2) : 240∼249, 2003)

Much attention has been given recently to solve the environmental contamination in golf courses Changing to culture practice rather than chemical practice that depends on pesticides and fertilizers is a hot issue in golf courses or grasslands. Organic soil conditioners improve soil-plant envirormental conditions rich in physical properties. In this study, measuring systems to evaluate soil conditioning effects were set up for on-site purpose. After establishing the methodology for evaluating soil conditioner effects, 2 kinds of organic conditioners were rested for examination. The systems for the methodology included a set of simulating equipment for field capacity, an impact type soil column compactor, and an infiltration-percolation system. Test results using the systems showed bulk density and infiltration rate of mixed soil were decreased at highter rates of conditioner, but total porocities were increased. Increased porocities were most capillary pore space which has a positive effect on soil water potential. The systems and methodology in this study seem to have an efficiency to measure the effects of soil conditioner on site purpose.
