한길로,황적준,김윤신 大韓法醫學會 1998 대한법의학회지 Vol.22 No.1

For 6 months, we experienced 3 cases of unexpected sudden cardiac death unrelated with coronary disease, from 43 cases of forensic autopsy. Diagnosis of each case is aneurysm of Valsalva sinus, dissecting aneurysm of aorta and hypertrophic cardiomyopathy, respectively. All of them are young adult male under 30 years old. They had never recognized their disease before their death and they were found dead in the morning. These are very rare cardiovascular disease and are related with sudden death. So we report 3 cases of sudden cardiac death with review of articles.

In this study, we discussed littroal movement and sedimentation of Keum-river estuary and estmated of deposition capacity. Keum-river estuary sea wall was constructed in 1988 Jan. and the sluice gate was completely closed in 1995 May. At the present, Kun-Jang new port. South and North jetty, Semankume sea wall and Kun-Jang industry estate are developing the Kume-river estuary around. At this developing and construction of Keum-river estaury, in many element of hydrauli - ocean waves, tide, tidal prism and depth of water - have changed. Tide analysis used statistics-analysis and harmonic-analysis from 1984 to 1997. Depth of water analysis used bathymetric chart from 1985 to 1997. Therefore we must correctly decise hydraulic element that is use simulation numerical test and hydraulic model. We analyze ocean waves, tide, tidal prism and depth of water change and modeling bed-load movement simulation; K-Cytengel, suspending-load deposition simulation; DIMOS-IV. Through the K-Cytengel and DIMOS-IV simulation estemated the sedimentation capacity and propose suitable answering such as dredging, water injection and remove of estuary sea wall.

Backgroud: Despite continous efforts to improve the prehospital trauma care system in Korea, the preventable death rate has been reported to be high. The purpose of this study was to evaluate the prehospital trauma care system in Seoul by analyzing 119 rescue databases. Methods: The 119 rescue data bases of 22,275 trauma patients, who were transported to the secondary and tertiary hospital in Seoul by Seoul 119 rescue services from January 1, 2000 to December 31, 2000, were analyzed. Results: The response time(mean 3.7 min.) showed no time, weekly, and regional variations. However, the transport time from field to hospital showed was high in the morning rush hour(7:00 to 10:00 am), and was gradually decreased and the lowest between 10:00 pm and 7:00 am. There was also a regional variation in the transport time, which was short in the central area and long in the peripheral area of Seoul. Prehospital cares were given to the 10,999 trauma patients(49.4%). Of the 464 unresponsive patients(2%), only 236 patients were identified in transported hospitals. The outcomes of these unresponsive patients were DOA(54%), survival(19%), death in ER(14%), transfer to other hospitals(8%), and death after admission(5%) in order. Conclusion: We suggest that this study may be helpful to the establishment and improvement of the prehospital trauma care system as well as the determination of the adequate numbers and locations of trauma center in Seoul.

대마의 저 마약형 신품종을 육성하고자 대마초의 환각성분에 대한 국내의 문헌을 수집하여 고찰하여 저마약형 대마 신품종 "청삼(Cheungsam)"을 육성하였던 바 이것들을 요약하면 다음과 같다. 가. 목포시험장에서 1997년 네덜란드 CPRO에서 도입한 44품종의 저 마약형 유전자원중 IH3이 THC 함량이 낮고 개화일수도 한국재래종과 비슷하여 경장과 섬유수량도 다른 도입품종들에 비해 크고 많아 육종재료로 유망시 되었다. 나. 저 마약형인 IH3를 모본으로 하고 한국 재래종을 부본으로 교배한 1대잡종 품종을 육성하여 무안 등 4개 지역에서 지역적응시험을 실시한 결과 특성이 우수하고 저 마약형으로 분류되어 이를 "청삼"으로 명명하여 신품종으로 등록하였다. 다. "첨상" 품종은 섬유수량은 190kg/10a로 재래종의 177kg/10a에 비하여 7% 중수되었고, 환각성분인 THC(Δ-9-Tetrahydrocannabinol)함량이 0.34%로 재래종의 1.74%보다 적고 환각억제성분인 CBD(Cannabidiol)함량은 1.34%로 재래종의 0.57%보다 많아 저 마약형으로 분류할 수 있다. 라. "청삼" 종자를 IH3의 자웅이주종자를 이용하여 채종하면 종실수량이 103kg/10a이지만 자성종자 채종기술을 이용하여 채종하면 146kg/10a로 채종량이 42% 증가하였다. In order to develop a new variety of fiber hemp(Cannabis sativa L.) with non-drug type, the authors reviewed several literatures about marihuana or hemp, and bred a new variety with non-drug type. This variety was named as "Cheungsam" and resitered as a recommening variety in Korea. This paper introduce the breeding history and characteristics of the fiber hemp variety "Cheungsam" with non-drug type. Among the 44 introduced germplasms from CPRO, Netherland, only IH3 was suitable variety because of it's good traits including low THC content, similar flowering days to Korean local variety and good fiber yield. IH3 and Korean local variety were crossed to develop a new non-drug type hemp, and we developed a new variety named "Cheungsam". This variety have good plant characteristics and fiber yield with low THC content. The average fiber yield of "Cheungsam" was 190kg/10a in regional fiber yield trials, which was 7% higher than that of "Korean local variety". "Korean local variety" contains 1.74% of THC which is the psychoactive ingredient and 0.57% of CBD the anti-psychoactive ingredient, thus that cultivar was sorted to drug type hemp. But "Cheungsam" contains 0.34% of THC and 1.34% of CBD so that sorted as a non-drug type hemp. If farmers want to harvest more seed of "Cheungsam", using female seed of IH3 is better than that of the dioecious seed because of the high seed yield.

This study was conducted to investigate the changes of physico-chemical properties of soil applied with compost made by food wastes and its effect on the growth and yield of Chinese cabbage. Chinese cabbage was grown in the soil treated with food waste compst(FWC) of 0, 0.625, 1.25, 2.5, 5 and 10㎏/3.3㎡. As the amount of FWC increased, number of leaves, leaf area and fresh weight increased where application of 5㎏ and 10㎏/3.3㎡ showed vigorous plant growth in the late growing period. The pH of soil by application of FWC was not raised, which was similar to the soil before treatment. Organic matter increased in soil by increasing the amount of FWC. However, concentration of Cu and Pb in the soil reduced. The concentration of available phosphate(P) was lower in the soil treated with FWC than in the soil before treatment, which means that a large amount of P may be uptaken by plant. This study suggested that FWC should be an alternative to chemical fertilizer for vegetable production.

KS F 2810-1:2001 adopts the concept of normal and standardized sound pressure level for the impact sound insulation performance. In these measurement, the equivalent sound absorption areas are ordinarily obtained by measuring reverberation time in the receiving rooms. However, measuring the reverberation time needs additional instrument and different procedures from sound pressure level measurement. Therefore it is very useful and desirable if the sound absorption area can be obtained only by measuring sound pressure level instead of measuring reverberation time. In this study, the principle of measurement method of equivalent absorption area by using reference sound sources and the measuring process are reviewed.

算術平均에 의한 바닥衝擊音 遮音性能 評價에 관한 硏究

장길수,남기봉,문연준 東新大學校 1999 論文集 Vol.11 No.-

It is known that arithmetic mean values of impact sound have an unexpectedly high correlation with the loudness of the sound. This measure is simple and much more easily obtained than the measures specified in tile existing standards. This finding was obtained by psycho-acoustic experiments, however, not by field experiments. This paper aims to specify the relationship between this measure and existing measure, L value by JIS A 1419, and to review the proper range of frequencies to be considered by using 63 data of actual impact sounds for domestic floors. As a result, arithmetic mean values of sound levels showed good correlation with L values. And mean values in octave bands from 125 to 2㎑ were proper for light weight impact sound and those from 125 to 2kH were proper for heavy weight impact sound. In addition it was found that L values(by JIS A 1419) estimated from same floor could be underestimated compared to arithmetic values.

미국의 식물유래약용물질(Plant-Made Pharmaceuticals, PMPs)의 안전성 규제

김태산,원소윤,이근표,류태훈,진용문,이길복,김현준 한국국제농업개발학회 2005 韓國國際農業開發學會誌 Vol.17 No.1

1. 식물유래 약용물질 (PMP)은 살아있는 식물에서 생산된 치료용 단백질로, 발효조에서 세포계통을 이용하는 것보다 적은 비용으로 높은 순도의 단백질을 생산할 수 있어 이에 대한 연구개발이 확대될 전망이다. 2. 식물유래 약용물질의 재배시험을 감독하는 주관부서는 미농무부(USDA)의 동식물 검역청(APHIS)이다. 3. PMP의 생산에는 알팔파. 옥수수, 벼 잇꽃과 담배 등이 이용되고 있다. 4. 현재 상업화된 PMP는 없으나 ProdiGene, Inc사 등 몇몇 생명공학 회사에서 이들의 연구개발이 진행되고 있다. 5. 2002년에 PMP 재배시험은 130에이커 규모로 34개 시험장에서 20건이 허가 되었으며 주별로는 애리조나, 네브라스카 등 14주에서 시험이 이루어 졌다. 6. 미국 USDA의 PMP 재배 지침에 의하면 PMP의 재배생산에는 안전성확보를 위한 별도의 전용장비를 필요로 하며 파종에서 생산까지 엄격하게 관리된다. 7. 미국 USDA의 APHIS는 2002년 PMP 옥수수를 생산하는 ProdiGene, Inc사에 대하여 2건의 포장시험허가 위반사항을 적발하여 벌금 조치를 한바있다. Plant-made pharmaceuticals(PMPs) are therapeutic agents(pharmaceutical proteins) produced in genetically engineered plants. To yield these valuable products plants offer several advantages that include large-scale production capacity at a reduced cost, equivalent purity/activity to other manufacturing systems, and freedom from contamination with animal pathogens, prions, or disease-causing germs. But there are risks of contamination of the food supply and unintended effects on ecosystems. In the U.S. PMPs are regulated under stringent requirement of the U.S. Department of Agriculture(USDA) and the Food and Drug Administration(FDA). In this article, contamination incident with PMP corn engineered by ProdiGene, Inc will be briefly introduced and regulations of PMPs will be discussed.
