최근 대학의 공학교육에서 학생 포트폴리오가 자기주도적 수행평가로 널리 활용되고 있다. 특히 여러 대학의 공학교육혁신센터와 한국공학인증원의 포트폴리오 경진대회를 개최하면서 많은 학생이 대학 전 과정의 수행실적을 담은 학생 포트폴리오에 참여하고 있다. 그러나 공학교육에서 캡스톤디자인 관련 과목을 제외한 정규 교과목에 교과목 포트폴리오를 적용하는 사례는 그리 많지 않은 것이 현실이다. 포트폴리오는 학습 관련 자료의 조직적인 수집과 비판적인 성찰의 기회를 주는 시스템이라 할 수 있다. 본 논문은 이러한 연구 배경으로 교과목 포트폴리오를 공학교육의 일반 정규 강좌인 2013년 1학기 자료구조 교과목에 적용한 사례 연구이다. 교과목 포트폴리오를 정규 교과목에 적용한 결과 교과목 포트폴리오는 학습에 효과적이었으며, 학습자는 학습의 탐구과정을 통하여 자기주도적인 학습능력을 키우고 학습과정에서도 자기 성찰로 학습과정을 체계적으로 관리할 수 있다고 판단된다.

This study aims to provide useful basic materials for planning the Health Improvement Program and Policy for men aged 20 40. This study investigated 889 subjects, and at each corresponding age, who were collected among the trainers at the Civil Defense Training Institute in K-ku, Incheon City. The data collection period lasted from April to July of 2003. I revised and complemented the measurement tool for the Health Improvement Life Style developed by Jung Eun-Kyung. For analysis of the acquired data. I used SPSS11.0 program. The study shows that the Health Improvement Action of a group of middle aged men averaged 2.80, and 0.44 point out of 5. According to the results found during the analysis of the generic characters of differences in behaviors of Health Improvement. It was revealed that there were significant differences in age, regular exercise and health interest, stress management, self-concept as well as degrees of interest in health, and education level. According to monthly income levels, regular exercise and degrees of self-concept degrees were significantly different from each other. According to marital status. balanced diet and regular exercise were related to each other. According to religion, balanced diet, stress management degree, self concept degree, and degrees of interest in health, significant differences were shown. Based on the earlier mentioned results, we should pay attention to act more, rather than merely recognize the development of the health improvement program of our regional community. Also, it is necessary to find out the cause, which lowers men's interest in health.

This paper analyzes the vibration characteristics within the cargo compartment of a three-wheeled cargo bike when used on both regular roads and dedicated bicycle lanes. When cargo is loaded into the cargo compartment of a cargo bike and driven on the road, the shocks and vibrations transmitted from the ground can potentially affect the transported goods and even lead to product damage. As the vibration characteristics applied to the cargo compartment may vary depending on the condition of the road, vibration sensors were attached to the cargo bike's cargo compartment for data collection during operation on different road types. According to KS T ISO 13355 standards, the cargo bike can withstand vibrations within the range of 10 Hz to 60 Hz when operating on both bicycle lanes and regular roads. However, it is observed that there are peaks exceeding the profile in the frequency range of 3-6 Hz. In the 70-200 Hz range, the profile is exceeded on both regular roads and bicycle lanes, with a tendency for higher exceedance on bicycle lanes. The Grms value within the frequency range of KS T ISO 13355 is 5.926 m/s² (0.604 Grms). When operating on bicycle lanes with cargo, the Peak envelope optimization PSD value is 6.553 Grms, while on bicycle lanes, it is 7.708 Grms, indicating a difference of at least tenfold.

In this work, we wanted to develop a probiotic from famous longevity villages in Korea. We visited eight longevity villages in Korea to collect fecal samples from healthy adults who were aged above 80 years and had regular bowel movements, and isolated lactic-acid-producing bacteria from the samples. Isolated colonies that appeared on MRS agar containing bromophenol blue were identified by means of 16S rRNA sequencing, and 102 of the isolates were identified as lactic-acid-producing bacteria (18 species). Lactobacillus fermentum was the most frequently found species. Eight isolates were selected on the basis of their ability to inhibit the growth of six intestinal pathogens (Escherichia coli O157:H7, Salmonella enterica subsp. enterica Typhimurium, Salmonella enterica subsp. enterica Enteritidis, Enterococcus faecalis, Staphylococcus aureus, and Listeria monocytogenes) and their susceptibility to 15 antimicrobial agents. Among these eight isolates, four Lactobacillus fermentum isolates were found not to produce any harmful enzymes or metabolites. Among them, Lactobacillus fermentum isolate no. 24 showed the strongest binding to intestinal epithelial cells, the highest immune-enhancing activity, anti-inflammation activity, and anti-oxidation activity as well as the highest survival rates in the presence of artificial gastric juice and bile solution. This isolate, designated Lactobacillus fermentum PL9988, has all the characteristics for a good probiotic.

The Fish Collection Project collected 356 fish species from the Southern Sea of Korea during 2010-2012, 55 more than previously collected. The fishes belonged to 3 classes, 29 orders and 128 families. The 5 dominant orders, Perciformes, Scorpaeniformes, Pleuronectiformes, Tetraodontiformes, and Clupeiformes, accounted for ~80% of the identified species. Additionally, 126 species were collected from the Southern Sea for the first time, while 85 species that had been found in previous collections were not seen. The species variety of fish in the Southern Sea may be influenced by its unique oceanographic conditions such as increased water temperatures in coastal areas, so regular surveys would assist our understanding of the fish community. We suggest that various collection methods, including diving, be used to collect fish species inhabiting rocky shore or deep-sea areas, where commercial fishing gear is difficult to deploy.

Kyujang-gak was an institution established by the King Jungjo's order to enshrine and edit the royal writings and autographs, and to help the revival of learning with more active services in collection, control, and use of the important materials. Furthermore, it was aimed in its establishment to promote the settlement of an innovative and ideal Royal Regime. In this paper, the Outer Kyujang-gak(外奎章閣) of Kangwha Magistracy(江華府), which was one of the lower branches of the Kyujanggak(奎章閣), will be treated, especially about its details of establishment, location, functions, the characteristics and value of its collection. After the Japanese invasion of Korea in 1592, the Historical Deposit Library(史庫) was established at the Kangwha Magistracy to take custody of the royal writings and autographs. An Annex(別庫) was built near by the Historical Deposit Library to enlarge the space in the reign of the King Hyojong. These spaces, however, become insufficient as the amount of materials deposited expanded, and custody for them was also not successful. Therefore, at the April of the 6th year of the King Jungjo's rule, the Outer Kyujang-gak was built at the east of the Temporary Palace(行宮) within Kangwha Magistracy, where the royal materials were deposited. This Outer Kynjang-gak was also called 'Kangdo Oe-gak(江都外閣)', 'Kyujang Oe-gak(奎章外閣)' or 'Simdo Oe-gak(心都外閣)', and its major function was to take custody of the materials and to hand them down to the next generations forever. The Kandwha Magistrate(江華留守) was responsible for the management of the Outer Kyujang-gak. Regular events for the book keeping were enshrinement, inventory and airing. In the 6th year in the reign of the King Jungjo, 4,892 volumes consisting of 762 titles were moved here from the Bon-gmodang(奉謨堂), the Seoseo(西序) in Main Palace, the Annex(別庫), the Deposit Library(史庫) mentioned above, the Kaegsa(客舍) and Chaeg-go(冊庫) within Kangwha Magistracy. By the end of the Joseon Dynasty, through fourteen times of addition altogether, the number of collection enshrined here reached 6,400 volumes consisting of 1,212 titles. The significance of this Outer Kyujang-gak established at the Kangwha Magistracy is in the point that this was one of the most important deopsit libraries of the Joseon Dynasty.

Standard uroflowmetry measures the urine weight using single load cell to evaluate the urinary flow rate. Impact noise should be introduced due to gravity when the urine stream falls down into the container upon the load cell. The present study placed three load cells on the three vertices of a regular triangle and the three signals were ensemble averaged to enhance the signal-to-noise ratio(SNR) regardless of how the urination was made. Simulated urination experiment was performed with three different urine collection methods. In all three methods, SNR of the averaged signal was much higher than each load cell signals. With no urine collection device, the present signal averaging technique resulted in SNR values higher by 10~15 dB than when dual funnels or upper funnel were used to guide the urine stream. Therefore, it was demonstrated that the three point measurement followed by with ensemble averaging could enable accurate uroflowmetric test without any specially made urine collection devices.

심층 웹 수집은 검색 양식에 질의어를 입력하고 응답 결과를 수집하는 것을 의미한다. 심층 웹이 가진 정보는 정적으로 구성되는 표면 웹보다 약 450~550배 이상의 정보를 가지고 있을 것으로 추산한다. 정적인 방식에서는 웹페이지가 새로 고쳐지기 전까지 변화된 정보를 보여주지 못한다. 동적 웹페이지 방식은 실시간으로 필요한 정보가 갱신되어 웹페이지를 새로 불러오지 않아도 실시간 정보 제공이 가능한 장점이 있지만, 일반적인 크롤러는 갱신된 정보에 접근하는 데 어려움이 있다. 따라서 이들 심층 웹에 있는 정보들을 크롤러를 이용해 자동으로 수집할 방안이 필요하다. 이에 본 논문은 스크립트를 일반적인 링크로 활용하는 방법을 제안하였으며, 이를 위해 클라이언트 스크립트를 일반 URL처럼 활용이 가능한 알고리즘을 제안하고 실험하였다. 제안된 알고리즘은, 검색 양식에 데이터를 입력하는 일반적인 방법 대신 메뉴 탐색 및 스크립트 실행으로 웹 정보를 수집하는 데 중점을 두었다.
