The covalent attachment of ubiquitin to proteins plays a fundamental role in the regulation of cellular function through biological events involving abiotic of biotic stress responses, immune responses, and apoptosis, Here, we characterize the biological function of the Arabidopsis thaliana RING Zinc Finger 1 (AtRZF1) in dehydration response. AtRZF1 was significantly reduced by drought stress. The atrzf1 mutant was less sensitive to osmotic stress than the wild-type during early seedling development, wheareas transgenic pants overexpressing AtRZF1 were hypersensitive, indicating that AtRZF1 megatively regulates drought-mediated control of early seedling developmeng. Moreover, the ectopic expression of the AtRZF1 gene was very significantly influential in drought sensitiv parameters including proline content, water loss, membrance ion leakage and the expression of dehy-dration stress-relat genes. ARZF1 is a functional E3 ubiquitin ligase, and its conserved C3H2C3-type RING domain is likely important for the biological function of AtRZF1 in drought response. Together, these results suggest that the E3 ligase AtRZF1 is an important regulator of water deficit stress during early seedling development.

Uniform Customs and Practice for Documentary Credits (UCP) operated world-widely has been revised four times and the recent revision made in June, 1983 which came into effect on October 1, 1984. International Chamber of Commerce (I.C.C.; funded in 1919) draws up the rules on the documentary credits which are used to effect payment for goods, keeping up with major changes which affects international trade. UCP was established in 1933 with the support of United States. The position of America in international trade has become greater since World War 1 and they faced various disputes on credits over 1930s world depression. That's why U.S. welcomed the idea of uniforming the rules on credits. UCP, made up of General Rule, 5 parts, 49 articles, was not adopted at first by U.s. and U.K. They made some reservation for adoption. The reservations were made about charter party B/L, received B/L, Insurance Certificate, partial shipment. And so the established rule was mostly based on European principle. * * * UCP was revised first in 1951(effective January 1, 1952). This revision covered American references and made harmoney with the existing European principle. The countries adopting this rule increased to 77 countries and standard from of letter of credit was adopted. UCP was revised again in 1962(effective July 1, 1963) with UK adoption of this rule. The language of UCP was changed from French into English and UCP became world-wide except some communist countries (Red China). UK principle affected this rule, making it stricter, comprehensive, abstract. For example, the governing clause should be contained in L/C and UK contended that option clause(may) should be abolished. For the third time UCP was revised in 1974 (effective ON October 1, 1975) to keep up with the development of combined transport. The definition of combined transport and the acceptability of received B/L were made and clauses (except clause 41) were abolished. * * * The fourth and l test revision, adopted in June 1983 and become effective on October 1, 1984, supplemented the third revision mainly in the field of combined transport, also covering the change of payment method-stand-by L/C and deferred payment L/C. and more or less clause(±3%→±5%). The structure has been changed into 6 chapters, 55 articles. And the shipping documents are now called transport documents. The summing-up of the fourth revision in case of transport documents is as follows: -Copies are treated as originals. -Transport documents are divided into three kinds: 1) Transport documents excluding marine B/L, post certificate 2) Marine B/L 3) postCertificate -Division of the acceptability has been made: 1) will accept 2) will not reject, 3) will reject -Post certificate: accept and partial shipment possible with same certificate -In case of marine B/L: almost the same as the old rule: Combined Transport Documents: much change; Refer to the follwing table for the chaange and comparision between old rule and new rule: oldrule newrule form specify or accept as presented short from, blank endorsement issuer " " carrier or his agent freight forwarder and person locally qualified " indication of on-board on board or not indicated dispatch taking in charge, or on board "intended"(vessel,port) none not reject transhipment:definition reloading of the goods reloading of good and the conveyance(vessel) acceptability B/L for entire voyage B/L for the course of carriage Revision trend can be concluded as follows: 1) Keeping with the development of means of transportation and communication and other technologya; Clearer definition of combined transport and its document; accepting copies as originals 2) Realization of new types of transaction: stand-by L/C, deferred payment L/C, BWT, more er less clause 3)Compliance with other international rules: CIP, expected profit 4) Strict interpretation: option clause abolished; insertion of governing clauseRevision trends 1) 3) are desirable for the rules to be living and interlinking with other rules, but strict interpretation draws our attention because stricter interpretation will make L/C transaction strict, which will cause decrease in international trade. Therefore, clear guideline of rules and cooperation of the parties concerned are more desirable. If not, more service of the banks is required. And clearer definition of stand-by L/C is also required in terms of form, revocability, ect.

FOB·CIF의 比較 硏究

鄭賢宇 釜山水産大學校 1983 論文集 Vol.31 No.-

FOB and CIF are the chief terms used in international trade contracts. But the problem is that these terms are the outgrowth of custom and usages of merchants and the same terms are interpreted differently in different countries. I.C.C. (International Chamber of Commerce) and other organizations made attempts to provide uniform international rules for the interpretation of the terms. The major rules are Incoterms by I.C.C., Revised American foreign Trade Definitions (RAFTD), the Uniform Commercial Code(UCC) and Warsaw-Oxford Rules (W-O Rules). And another problems arises here. The interpretation of the terms provided by organizations are not the same, making slight difference in meaning and effect. Therefore, this study is designed to see into the historical background of the two main instruments FOB and CIF, analyze the fundamental differences between two terms FOB and CIF, and the differences in interpretation made by the organizations, clarify the uncertainties concerning these terms and present reasonable solution. Incoterms published by I.C.C. and revised in 1936, 1953 are accepted as most authoritative. RAFTD, adopted first in 1919 in National Foreign Trade Convention, U.S.A. and revised in 1941 are devised to suit the geographical characteristics of America. The Uniform Commercial Code, announced in 1952 and adopted first by Penn. State in 1954 covers almost all the states. W-O Rules, established by International Law Association in 1928 is the representative interpretation of CIF. The main differences found through this study of the international rules concerning FOB and CIF can be summed up as follows : 1) Transfer of Property a) In case of FOB, property in goods passes on shipment but the time of shipment is interpreted differently. Under Incoterms it is the time of effectively passing the ship's rail; under RAFTD it is when the goods are placed on board the vessel and under UCC, it is when the goods are placed on board the vessel. And in order to prove shipment, under Incoterms M/R is required and under RAFTD clean ship's receipt or on board B/L is required. b) In case of CIF, B/L is a matter of interest. On Board B/L is in principle required but RAFTD and UCC and W-O Rules accept received B/L. 2) Transfer of Risk The general rule for transfer of risk is that the risk passes with property but risk under FOB and CIF passes on shipment. The time of shipment is interpreted differently as shown in (1). 3) Cost or Charges FOB is not "C" of CIF in a strict sense, for the passing of property under CIF is based on documents an the cost should include the cost of tendering documents. And the following charges should be examined because it is not clear whether they are for account of seller or buyer. a) Stevedorage In case of Liner, stevedorage is paid by the party responsible for freight, that is, buyer under FOB and seller under CIF. But in case of charter, the owner of the goods should pay the stevedorage based on FIO (Free in Free out) which is accepted as general principle. But seller is responsible for shipping and loading, not stowing under Incoterms and so buyer should pay the stevedorage. Under RAFTD, seller is responsible for stowage, for seller's duty is to place the goods on board the vessel. The two rules take different positions and so prior agreement between seller and buyer is desired, employing such terms as "FOB ST" "FOB including Stowing". b) Auxiliary Documents As for B/L, Incoterms (FOB) requires seller only to furnish M/R and so the cost concerning B/L is for account of buyer but under RAFTD it is seller's account. As for auxiliary documents such as Certificate of Origin or Consular Invoice, both Incoterms and RAFTD require buyer to bear the costs and seller to assist with obtaining the documents. But W-O Rules stipulates that it should be equally borne by seller and buyer. c) Other Charges Clearance fee should be borne by seller under Incoterms but by buyer under RAFTD. Aand negotiation changes should be borne by seller but such other charges as commission, maildays or usance interest or cost of exchange are ambiguous. The agreement is also needed here, using such variations as CIF&E, CIF&I, CIF&C. 4) Variation of FOB and FOB of particular Contract Under FOB, transport and insurance arrangements should be made by buyer but there are occasions when seller does so in place of buyer. Yet, in this case it is different from CIF in legal position. Under variant FOB, the seller is requested to do so by buyer, so he is not responsible for the disadvantage in the event that the ships cannot be chartered or ship's space are not available and cannot be reserved. Particularly-contracted FOB, which is far from traditional FOB, is nowadays in much use with the increase L/C-based transaction. In this case, the property passes at the same time as CIF, that is, on tendering the documents. It is true that the risk passes on shipment, but the problem arises when buyer refuses to accept the documents, to pay the price or to accept the bill. The damage to or the loss of the goods cannot be recovered under the circumstances and seller is forced to bear the risk from the time of shipment because the passing of property under particularly-contracted FOB is retroactive to the time of shipment. FOB is the term which is historically older and in wider use, which has become more complicated with the introduction of RAFTD in America. CIF is the term which makes reasonable division in duties between seller and buyer naturally and it is increased use with L/C transaction. The comparison between two terms can be summed up in the following table: -------------------------------------------------------------------------------- shipping insurance risk property delivery price port passing passing factor based -------------------------------------------------------------------------------- FOB buyer buyer shipment shipment physical single shipment -------------------------------------------------------------------------------- CIF seller seller shipment documents docum- complex destination tendered entary -------------------------------------------------------------------------------- Therefore, CIF is generally better term than FOB or particularly-contracted FOB, for it suits well documents-based transactions with less problems. But FOB is advantageous to both parties in the following special cases; a) when buyer owns ships or has branch offices at the destination port to handle shipping and insurance in an advantageous position or the goods are such bulk cargo as to charter a vessel and b) seller as a producer or manufacturer is not specialized in international trade or the market for shipping and insurance are not stable and freight and insurance premium are expected to rise. So, for more use of CIF which is more desirable to both parties, the way to be able to adopt CIF to container transport and air cargo should be sought by recognizing and accepting received B/L, and transforming Airway Bill into B/L.

北漢山의 植物資源調査硏究 : 第1部 管束植物 Resources in Mt. Buk-Han PartⅠTracheophyta

鄭台鉉,李愚喆 成均館大學校 1962 論文集 Vol.7 No.-

Mt. Buk-han is located in the northern side of Seoul, Korea; whose flara has been seriously destroyed due to the population increase of the city the constant Mountain climbers. The Plants of this mountain were first collected by Gotlsche, C. in 1883 when he collecetd plants in the entire vicinity of Seoul, and the flora of this mountain has been partly surveyed by several scholars, but no one has ever comprehensively surveyed the flora of this mountain as such. The writers is now presenting the results of their 9 times survey made from 1961 to 1962 as a part I of the entire flora specified as Tracheophyta. The result of this study is as follows: 1) The plants of Mt. Buk-han are composed of 114 families, 228 genera, 347 species, 94 varieties, 9 forma and 450 kind in all. 2) As the population of Seoul City has increased and their footprints got frequent, a disorder of the original flora of this mountain has occurred; Buxus Koreana, Utricularia bifida, Lactuca chelidonifolia, Sasamorpha purpurascens var. borealis have been disappeared consequently. 3) Comparing the flora of Mt. Buk-han with that of other mountains, 262 species were in common with Mt. Hanla (Ir. Querpart), 142 species are with Ir. Dagelet (Ulneung), 226 species with Mt. Sulak, and 18 species with Mt. Baek-doo. These facts show that the sothern floral elements such as Cocculus trilobus, Akebia quinata, Achgranthes japonica, Zelkova serrata, Viburnum erosum var. punctatum are believed to thrive in Mt. Buk-han which is in accord with northern line of temperate zone T. Nakai had named by means of climate of Korea.

본 연구에서는 여성의 고용환경을 사회·경제·문화적 측면에서 긍정적 요인과 부정적 요인별로 살펴보고, 남녀임금격차에 영향을 미치는 요인은 무엇이며, 임금격차가 성차별로 인한 것인지 아니면 생산성 차이로 인한 것인지를 분석하고자 하였다. 자료는 대구시에 있는 98개의 기업체에 근무하는 910명의 근로자를 대상으로 1995년 9월에 설문조사를 실시하여 수집하였다. 분석결과는 여성에게 성차별이 존재하듯이 남성에게는 생산성차별이 존재하고 있음을 시사하고 있다. 즉 남녀임금격차 중 63%는 여성의 낮은 생산성 때문이고 나머지 37%는 논리적 근거을 갖지 못한 남녀차별에 의해 발생한 것이라는 것을 말해 주고 있다. 연구결과를 토대로 여성에 대한 임금차별을 불식시키고 여성의 경제활동참가율을 높이기 위한 제언과 정책대안을 제시하고자 하였다.

Radiocobalt의 體內 汚染에 對한 除染效果

정인용,정현우,김태환,진수일,윤택구 대한방사선 방어학회 1988 방사선방어학회지 Vol.13 No.1

국내 原子力 産業의 施設增大로 放射線核種汚染의 가능성이 날로 증가되고 있음에도 불구하고 종사자 및 인근주민에 대한 診療對策에 관한 연구가 전무한 실정에 있어 이에 대한 기초자려마련의 일환인 應急處置方案을 수립코자 58CoCl2 1μCi를 마우스 (NIH-(GP))의 腹腔內에 投與한 후 CoNa3 DTPA 8.4mg/0.2ml saline, CoNa3 DTPA 8.4mg/0.2ml saline, saline 5ml등을 각각 投與하였으며, cobalt의 全身殘存量, 體內分布 및 尿內 含有된 量을 測定하기 위해 投與 後 4, 8, 12, 48시간, 그리고 7일에 MCA의 Ge-detector로 放射能을 計測하였고, 또한 각 實質臟器內 殘存된 cobalt의 放射能을 測定하기 위하여 각 group당 6마리의 마우스를 屠殺解體하여 測定하였던바 다음과 같은 결론을 얻었다. CoNa3 DTPA 處置群에서는 汚染된 放射性 cobalt의 全身殘存率의 減少 및 排泄率 增加에 유효한 效果가 있었으며, system contamination에 대한 방어효과는 CoNa3 DTPA, CoNa3 DTPA 그리고 saline 順으로 유효하였다. 결론적으로 본 실험결과로 볼 때 放射性 cobalt의 體內汚染에 대한 緊扱措置는 CoNa3 DTPA와 다량의 물을 동시에 投與함으로써 體內汚染된 放射性 cobalt의 排泄을 促進시킬 것으로 사료된다. In case of the acute intake of radionuclide, an early medical treatment may be necessary, but the little is established the procedures to decontaminate the victims of internal contamination in Korea. The purpose of the present investigation is to study chemical agents to remove radiocobalt from the victims and to provide a more reliable procedure for the treatment. The removals of radiocobalt from the NIH-(GP)mice injected intraperitoneally with lμCi of 58Co as CoCl2 were investigated with doses of either CaNa3 DTPA 8.4mg/0.2ml saline, CoNa3 DTPA 8.4mg/0.2ml saline, or saline 5ml. The radioactivity was determined by MCA and Ge-detector on 4, 8, 12, 48 hours and 7 days for the whole body, organ distribution and urine excretion. Six mice per each group were sacrificed for the measurement of cobalt retention in the parenchymal tissue. The cobalt trisodium chelate had a pronounced effect on reducing the whole body retention and increasing the excretion rate. Regarding to the systemic protective effects, CoNa3 DTPA, CaNa3 DTPA and saline were effected significantly in order. In conclusion, the extrapolations from these results to human were suggested that the rapid administration of cobalt trisodium chelate and an amount of saline to the contaminated person after internal contamination of radiocobalt were markedly increasing the decontamination effects.

The Taegeuk Poomse 1 through 8 of Taekwondo are based upon eight major branches of philosophical theories. The propose of this study was to investigate the nfluence of Taekwondo poomse trainning on heart rate, MVO2, energy metabolism in primary school students. Subjects for this study were eight male the fifth∼sixth grades students who participated in exercise program consist of Taekwondo poomse trainning in dojang which is located in Shinlim-2dong, Kwanak-Gu, Seoul(12.7± 0.5years, 150.8 ±4.6cm, 45.1 ± 9.4kg, 24.9 ± 9trainning length). The results of thet this study are as follows: 1) The average of heart rate was Taegeuk Poomse 1 through 8 of Taekwondo 90.57± 4.gbeats/min in rest and 139.7 ± 17.5beats/min in exercise. The minimum heart rate was 89.0±2.8, peak heart rate was 167.1 ±6.4 in exercise. It was ranged from 42% to 80% 2) of the max heart rate and ranged 42 to 65%HRmax. Taegeuk 1 Jang was differenced with others Jangs significantly(p<0.05), 2) The time of the Taegeuk 1 through 8 Jang of Taekwondo was 5minutes 12seconds. Heart rate was ranged from 90.6 ± 7.85beats/min to 171.8 ±8.Ibeats/min and increased linearly. 3) The average of the MVO2 was 11.1 ±0.78mmHg · bpm-3 in rest and 19.1 ± 1.2mmHg ㆍbpm-3 in exercise. MVO2 was ranged from 10.5mmHg · bpm-3 to 20.3mmHg · bpm-3. There were not difference between Taegeuk Poomses(p<0.05). 4) The energy metabolism was as follows: Mean VO2 Respiratory exchange ratio, energy consumption were 0.51(V02L/min),0.71(RQ),2.32Ckca1/min) in rest respectively. but In exercise Mean VO2 Respiratory exchange ratio, energy consumption were 0.89 ± 0.18( V 02L/min), 0.79±0.08(RQ), 4.26±0.51(kcal/min) respectively . The difference was only between Taegeuk 1 Jang and Taegeuk 3 Jang(p<0.05). This study showed that the Taekwondo Poomse trainning was proper exercise for fitness, body composition and weight control in normal, abnormal(obese) children because the Taekwondo trainning are dynamic and exciting sport.

유아용 조제 분유가 치태 pH에 미치는 영향에 관한 연구

정우진,이상훈,한세현 大韓小兒齒科學會 1998 大韓小兒齒科學會誌 Vol.25 No.1

Infant formula in nursing bottle, with inappropriate feeding habits, is major factor associated with the development of nursing caries. Although each infant formula has different carbohydrate and protein composition, studies comparing cariogenic potential of many Korean-branded infant formulas are deficient. In addition, it is on the point of being difficult to evaluate the cariogenecity of milk due to development of many infant formulas. In this study, to evaluate the cariogenic potential of many infant formulas, after oral rinse with six Korean-branded infant formulas(three milk based formulas, one soy based formula and two specific formulas for infants with allergy to milk protein and with lactose intolerance) for ten adult volunteers(eight males and two females), plaque pH change was measured with In vivo/In vitro combination technique and results were as follows. 1. All six different kinds of Korean-branded commercial infant formulas dropped the plaque pH significantly(p<0.05) and at an hour after rinse, plaque pH was not recovered in most of subjects. 2. Soy based infant formula and casein-hydrolyzated infant formula containing no casein dropped the plaque pH significantly more than milk based infant formula containing casein(p<0.05). 3. In the milk protein of infant formulas, casein had more effect on buffering the pH change of the infant formula than whey protein and casein-hydrolyzated infant formula had a refuced effect of casein. 4. In infant formulas with similar protien composition, infant formula containing sucrose dropped plaque pH more than infant formula containing lactose, but there was no significant difference(p>0.05).
