야포분야는 수적으로 북한군이 아측에 비하여 2.3배의 우위를 점하고 있다. 수적인 열세를 만회하기 위하여 화력의 발사속도를 증대시켜 포 1문의 능력을 극대화해야 한다. 현재의 자주포에 사거리 연장, 발사속도 증대, 반응성을 향상시킨다면 자주포 1문이 같은 운용 병력으로 대략 2문의 효율을 갖게 될 것이다.

The research project was conducted to develop a paper bagging machine for grape. This technology was aimed to highly reduce a labor for paper bagging in grape and bakery. In agriculture labor and farm population has rapidly decreased since 1980 in Korea so there was so limit in labor. In particular there is highly population in women and old age at rural area and thus labor cost is so high. Therefore a labor saving technology in agricultural sector might be needed to be replaced these old age with mechanical and labor saving tool in agriculture. The following was summarized of the research results for development of a paper bagging machine for grape. 1. Development of a new paper bagging machine for grape - This machine was designed by CATIA VI2/AUTO CAD2000 programme. - A paper bagging machine was mechanically binded a paper bag of grape which should be light and small size. This machine would be designed for women and old age with convenience during bagging work at the field site. - This machine was manufactured with total weight of less than 350g. - An overage bagging operation was more than 99% at the actual field process. - A paper bagging machine was designed with cartridge type which would be easily operated between rows and grape branches under field condition. - The type of cartridge pin was designed as a C-ring type with the length of 500mm which was good for bagging both grape and bakery. - In particular this machine was developed to easily operated among vines of the grape trees. 2. Field trials of a paper bagging machine in grape - There was high in grape quality as compared to the untreated control at the application of paper bagging machine. - The efficiency of paper bagging machine was 102% which was alternative tool for the conventional. - The roll pin of paper bagging machine was good with 5.3cm in terms of bagging precision. - There was no in grape quality between the paper bagging machine and the conventional method. - Disease infection and grape break was not in difference both treatments.

This study was performed to investigate the enrichment of resveratrol content in harvested grapes using the modulation of cell metabolism with ultra-violet (UV) irradiation. Resveratrol, a phytoalexin, is produced by stilbene synthase (STSY) from malonyl-CoA and ${\rho}$-coumaroyl-CoA. Its biosynthesis has been reported to be induced by UV and other environmental factors. Reverse transcriptase-polymerase chain reaction (RT-PCR) analysis showed that STSY Promoter 1 in grapes was very highly expressed by treatment with UV. Grapes were harvested and treated for post-harvest induction of STSY gene expression with UV, and then their resveratrol content was analyzed. UV treatment for 5 minutes provided the best condition for the induction of STSY gene expression. When harvested Gerbong and MBA grapes were treated with a prototype UV radiator, their resveratrol content was enriched upto 5 times compared with untreated grapes. These results suggest that a post-harvest UV treatment can be applied to enrich resveratrol content in grapes and add value to them.

This study was conducted to prepare high quality grape seed oils by solvent extraction and chemical refining process. Additionally, quantitative analysis of several functional components in grope seed was carried out to compare quality characteristics of grape seeds from grapes grown by conventional and organic agricultural practices. There are no significant differences in several functional constituents of grape seeds between conventionally cultivated- and organically cultivated-grapes, although some functional compositions of grape seeds are different between two cultivation methods. The dried grape seed was pretreated with roasting heating for 5 min, milled and then extracted twice with n-hexane under reflux at $50^{\circ}C$ for overnight, followed by filtration and evaporation. The crude grape seed oil was successively purified by degumming with $0.1\%\;H_3PO_4$, deaciding with $20\%\;NaOH$, and then decoloring and deodorization by a steam distillation, and thereby producing purified grape seed oil(yield: $5.0\%/dried$ grape seed). Physicochemical characteristics of the purified grape seed oil were comparable to those of the imported grape seed oils.

In the course of a study in relation to the production of taste, and functional enhancements in root crop chips, which were prepared by soaking dried yam slices in fruit juices, we investigated the physiological characteristics and biological activities of 8 different commercially available juices including; apple, omija (fruit of Maximowiczia typica), grape, wild grape, orange, tomato, red ginseng and black garlic juice. The average water contents, pH, brix and acidity of the juices used were $85.59{\pm}5.80%$, $3.90{\pm}0.64$, $12.19{\pm}4.70%$, and $0.49{\pm}0.19%$, respectively. The polyphenol content of black garlic and grape juice were 1.50 and 1.21 mg/ml, respectively, and those were higher than the average content (0.57 mg/mL) of the juices. Evaluation of anticoagulation activity showed that only omija juice has a strong thrombin inhibition, which is comparable to that of aspirin (1.5 mg/mL). Omija, grape and orange juice all exhibited antibacterial activity, but no antifungal activity. The 8 different juices, and in particular grape and black garlic juice, showed strong antioxidant activity in DPPH and ABTS radical scavenging activity assays, with wild grape juice demonstrating potent nitrite scavenging activity. These results suggest that omija, grape and black garlic juice can be used as soaking solutions to produce taste, and other functional enhancements, for root crop chips.

The purpose of our study is to investigate the changes of physico-chemical properties according to packaging methods(vacuum packaged with polyamide/polyethylene, air packaged with polyvynyl-chloride) and illumination on the properties of Hanwoo beef. pH value in vacuum packaged beef tended to be decreased, but pH value in air packaged beef tended to be increased during storage for 21 days, irrespective of illumination. Contents of volatile basic nitrogen(VBN) and thiobarbituric acid(TBA) values were increased, regardless of packaging methods. However, vacuum packaged beef showed lower VBN, TBA values than those of air packaged beef. Red color(CIE a value) was also decreased. Regardless of packaging method, saturated fatty acids(SFAs) were increased, but unsaturated fatty acids(UFAs) were relatively decreased. And in the ratio of the UFA/SFA, vacuum packaged beef had lower UFA/SFA ratio than that of air packaged beef. In this study, the effect of illumination did not change on physico-chemical properties in Hanwoo beef. In conclusion, the results indicate that the vacuum packaging treatment was more important to prolong the shelf-life of Hanwoo beef than air packaging method.

Photodynamic therapy(PDT) has been recommended as an alternative therapy for various diseases including microbial infection. The aim of the present study is to evaluate the antimicrobial effect of PDT using a photofrin and home made 630 nm Light emitting diode(LED) against Staphylococci. To examine the antimicrobial effect of photofrin-mediated PDT against Staphylococcus aureus and Staphylococcus epidermidis colony forming units(CFU) quantification, and bacterial viability using flow cytometry were formed. The CFU quantification results of S. aureus and S. epidermidis were 1 cfu/ml and 16 cfu/ml of average, respectively, after PDT application with photofrin of $50{\mu}g/m{\ell}$ and 630 nm LED and energy density of $18J/cm^2$. In addition, S. aureus and S. epidermidis isolates yielded forward-scatter (FSC) and fluorescence intensity (FI) differences on flow cytometry (FCM) after PDT. S. aureus and S. epidermidis cell size(FSC) increased 8.96% and 5.55% respectively, after PDT. Also the numbers of dead cell of S. aureus and S. epidermidis were a 39% and 61% incerased. These results suggest that photofrin-mediated PDT can be an effective alternative treatment for antibacterial therapy.

다대포 갯벌의 YP는 0.06~0.13 mg/L이었고 진우도의 TP는 0.06~0.11 mg/L로 조사시기별로는 두 조사지역간 차이는 없었고 TN은 다대포의 경우 1.44~2.87 mg/L, 진우도는 0.15~1.09 mg/L로 조사되어 매 조사시기마다 진우도보다는 다대포에서 월등히 높았으며 두 지역 모두 해역의 어염등급에 비추어볼 때 상당히 오염이 진행된 상태였다. 조사된 미세조류는 Navicula, Nitzschia, Cyclotella, Cymbella, Synedra 등 13속 26종류로 호청수성 조은 Achnanthes convergence 등 1속 2종류, 호오염성 종은 Nitzschia palea 등 5속 8종류, 광적응성 종은 Cymbella minuta 등 3속 5종류였으며 매 시기마다 우점을 보인 종은 Nitzschia, Navicula 였다. DAIpo 지수는 다대포의 경우, 평균 31.1 진우도는 평균 48.4로 조사되어 비교적 낮은 DAIpo 값을 보였지만 계절별로는 다대포와 진우도의 경우 모두 봄인 5월에 가장 높은 DAIpo 값으로 비슷한 경향을 보였으나 다대포의 경우에서는 매 계절마다 진우도보다 더 DAIpo값이 낮게 조사되었다. DAIpo 값으로부터 갯벌의 오염도를 판정하면 다대포는 $\alpha$-중부수성, 진우도는 $\beta$-중부수성에 해당하여 다대포의 경우가 진우도보다 더 오염이 심한 것으로 조사되었다.
