2018년은 해양 과학시추가 시작된 지 50년이 되는 해이다. 그럼에도 불구하고 우리는 지구의 대양저보다 달의 표면을 더 많이 알고 있을 정도로 지구내부에 대한 정보가 많지 않다. 대양저에 관한 연구는 해양 과학시추로부터 얻어진 시료를 통해서 알 수 있다. 이러한 심해의 시료획득은 50년 전인 1968년 8월 11일 미연방차원에서 지원된 심해저시추계획(DSDP: Deep Sea Drilling Project)에서 글로마 챌린저(Glomar Challenger)호를 이용한 멕시코 만 시추로부터 시작되었다. 이후 해저지각시추프로그램(ODP: Ocean Drilling Program), 통합해저지각시추프로그램(old IODP: Integrated Ocean Drilling Program), 그리고 국제해양시추탐사프로그램 (new IODP: International Ocean Discovery Program)으로 이어져 오고 있다. 해양 과학시추로부터 얻어진 가장 큰 성과는 두 가지 기술적인 성과와 다양한 과학적인 성과로 나눠진다. 첫 번째 기술적인 성과는 시추선이 시추위치를 벗어나지 않고 연속적으로 시추코어를 획득할 수 있도록 위치를 유지시켜주는 동적위치유지 시스템(dynamic positioning system)이다. 다른 하나는 시추동안 드릴 비트를 교체한 후 동일한 시추공에 드릴비트가 쉽게 투입될 수 있도록 해주는 재투입 콘(re-entry cone)의 개발이다. 이러한 기술적인 혁신 외에도 다양한 과학적 성과 즉 판구조론 증명, 지구의 역사 규명, 그리고 심해 퇴적물 내 생명체의 발견 등이 있다. 2013년 10월 시작된 국제해양시추탐사프로그램(new IODP)은 2023년까지 계속될 예정이고, 2023년 이후 다음 단계를 위해 참여 회원국들은 새로운 과학계획 수립과 더불어 미래의 해양 과학시추 50년을 준비하고 있다. 우리나라도 이러한 국제적인 동향에 발맞추어 회원국가로서 지속적인 참여와 다음단계를 위한 준비가 필요한 시점이다.

This study was conducted for the evaluation of the effects of singing program combined with physical exercise on the physiologic changes, perception function and degree of depression. The subjects were the members of elderly women's glee club in D care center for the elderly, who have been singing for more than 6 months. 30 members were allocated to study group and 30 to control group. The singing program designed for both physical therapy and music therapy was consisted of initial physical exercise, singing art songs and classical song and the finishing physical exercise. This program was performed twice a week and about forth minutes was consumed for one session. We checked the heart rate, peripheral arterial oxygen saturation, perception function and degree of depression before and after the program. We used a pulse oxymeter to check the heart rate to oxygen saturation and a questionnaire for the evaluation of perception function and degree of depression. We need SPSS program for data analysis. The results of the investigated personnel complying with general characteristics were analyzed by frequency, two groups by t-test, data before and after the program by paired t-test, respectively. The results were as follows. 1) Heart rate after the program was significantly lower than that before program in test group(p<0.05). 2) Peripheral oxygen saturation after the program was significantly higher than that before the program(p<0.05). 3) Ability to match the right sign with a certain predetermined number was improved after the program. The frequency of wrong matching the sign with number before program was 30. But the frequency was decreased to 8 after the program. 4) Ability to calculate was improved after the program. The frequency of wrong calculation before the program was $1.10{\pm}1.94$. But the frequency after the program was decreased to $0.97{\pm}1.84$. 5) The degree of depression after the program($2.07{\pm}0.49$) was significantly lower than that before program(p<0.001). These results show that singing program combined with physical exercise improves the oxygen delivery to peripheral circulation, stability of heart function, the perception function(calculating and matching ability) and decreases the degree of depression. In conclusion, singing program combined with physical exercise can be used for the effective measure to improve the health of elderly and prevent dementia.

본 연구는 캠퍼스 금연 교육 프로그램에 참여하고 금연에 성공한 대학생들의 장기금연 효과를 파악하기 위하여 실시되었다. 연구 대상자들은 2016년부터 2018년까지 서울시 소재 일개 대학에서 36주에 걸쳐 진행되는 캠퍼스 금연 교육 프로그램의 2차 자료와 참여 후 금연에 성공한 전체 금연성공자중, 연구에 참여하기로 동의한 30명이었다. 캠퍼스내에서의 흡연이 전면 금지되어 있는 서울시내 일개 대학교의 금연 교육 프로그램은 금연관련 교육과 상담, 주1회 소변 내 Cotinine 검사, 금연장학금 지급으로 구성되었다. 참여자의 평균 금연 성공률은 1차시 50.17%, 2차시 44.16%, 3차시 77.30%로 나타났으며, 2차 성공이후에 금연이 고착화되는 경향이 관찰되었다. 본 연구에서 금연에 성공한 이후, 12개월 이상 금연을 유지하고 있는 참여자는 51.22%, 흡연 재발한 참여자는 무응답 흡연자를 포함하여 48.78%이었다. 금연유지의 가장 큰 성공요인은 금연의지(28.57%)였으며, 금연유지의 가장 큰 실패요인은 스트레스(66.67%)로 나타났다 대학생을 위한 캠퍼스 주도적 금연 교육 프로그램은 대학생 흡연자의 금연유도 뿐 아니라 금연을 습관화하여 장기금연 유지자로 전환시키는데 효과적인 프로그램임을 확인할 수 있었다.

The objective of this study was to discover the effects of the short-term home visiting physical therapy program involving patients with some chronic brain disorders at Gimhae City, Kyongnam. Recovery of activities of daily living (ADL) is a very important factor of rehabilitative procedures, and Functional Independence Measure (FIM) is a useful standard of evaluation for it. The FIM is widely used in brain disorder research because it measures real functional activities of daily living. We applied the physical therapy exercise program twice per week (10~15 times repeatedly); a warm-up and cool down exercise performed every ten minutes by active & active-assistive ROM and stretching exercises. Main exercises were composed of getting up & laying down in bed, standing training, walking exercise in the room, and window or wall sliding exercise using affected upper limbs for a total duration of 30 minutes. We collected the data from 20 patients with chronic brain disorders at his/her home and analyzed by means of SPSS/PC+ program (Ver. 10.0). After the six week long physical therapy exercise program, the average was $56.10{\pm}22.59$ point compared with initial $50.55{\pm}19.12$ point by FIM, improved functional ADL ability about 5.55 point, and these changed scores were statistically significant (p=.000). We also studied another factor regarding patient's satisfaction. The majority of subjects (10 people) rated the program with the maximum score of ten points (50.0%), and three people rated it a seven point program (15.0%), the other two subjects gave a rating of nine and eight points (10.0%). Because the program was effective at improving the physical ADL ability and satisfaction of each subject, we suggest continual development and implementation of a home visiting physical therapy program. Further study should involve a longer period of observation with a larger population that is involved in an individually designed home physical therapy program.

전기화학적 증착 기법을 이용하여 간단하고 빠르게 3차원적 구조를 가지는 다공성 금 박막(NPGF : nanoporous gold thin film)을 금 기판 위에 제작하였다. 제작된 3차원적 구조의 NPGF는 주사 전자 현미경(SEM)을 이용하여 표면을 분석하였고, 이를 통하여 표면상에 30~50 nm 크기의 균일한 다공성 박막이 생성되었음을 확인하였다. Differential pulse voltammetry(DPV) 기법을 기반으로 3차원적 구조체를 가진 NPGF기판을 전극으로 사용하여 GABA를 농도별($10{\sim}100{\mu}M$)로 측정하였다. 본 연구에서 제안된 방법은 향후, 바이오센서 응용분야에 널리 사용될 수 있을 것으로 기대된다.

Duck farming restriction refers to a program in which duck farms suspend their operations for a certain period at times when the risk of avian influenza (AI) is high and receive compensation from the Korean government. This study analyzed the effect of this duck farming restriction on the incidence of AI using data on regional AI incidence rates, the program participation rate, and characteristics of poultry farming in 2016 (before the implementation of the restriction), as well as data from 2020 and 2021 (when new AI outbreaks occurred). In this study, the treatment group was divided into five subgroups according to the policy participation rate and a difference-in-difference (DID) estimation was conducted using certain covariates, in this case the average number of ducks raised, the land area, the number of high-susceptibility farms, the number of low-susceptibility farms, the average number of farms within a 3 km radius, the average distance to the nearest farm, and a year dummy. The results showed that when more than 30% of all duck farms in a region participated in the farming restriction, it had a statistically significant effect on the incidence of AI. Specifically, when more than 30, 40, 50, and 60% of all duck farms participated in the farming restriction, the AI incidence rate decreased by 0.7184, 1.0025, 1.5844, and 1.5843%p, respectively.

Purpose: To propose a new infusion rate monitoring technique based on the 2D image marker tacking to improve patient safety by preventing syringe pump-related medication accidents due to decreased infusion rate control accuracy. Materials and Methods: The infusion rate of the syringe pump and drug residue in the pump-equipped syringe were monitored in real time by tracking the movement of the 2D image markers attached to the syringe pump. Results: The error rate between the set and the estimated infusion rates was 1.03, 0.66, 1.95, 0.23, and 1.05% when the infusion rate setting was 10, 20, 30, 40, and 50 mL/H, respectively. In addition, the error rate between the actual and the estimated drug residues was 1.04, 0.47, 0.60, 3.66, and 0.00% when the infusion rate setting was 10, 20, 30, 40, and 50 mL/H, respectively. Conclusion: Experimental results demonstrated that the proposed technique can increase the efficiency of the safety management system for seriously ill inpatients by decreasing a possibility of syringe pump-related medication accidents in hospitals.
