한국재래간장으로부터 혈전용해효소를 강하게 생산하는 균주를 선발하고 이를 Bacillus subtilis K7로 동정하였다. B. subtilis K7이 생산하는 혈전용해성 protease를 정제하여 분자량을 확인한 결과 21,500 Da이었다. 정제된 효소의 최적반응조건은 $40^{\circ}C$와 pH 9.0이었으며 pH 5.0라서 12.0까지 안정하고 $50^{\circ}C$에서 20분간 열처리한 후에도 50%이상의 효소활성을 가지며 EDTA, CDTA 및 iodoacetat에 실활하는 효소이었다. 이 효소의 fibrin에 대한 Km 값은 $1.8{\times}10^{-2}$ M이었다. An alkaline fibrinolytic protease-producing bacteria was isolated front Korean traditional soy sauce and identified as Bacillus subtilis K7 from the results of analyses of its morphological and physiological properties, $API^{\circledR}$, and Biolog system. The enzyme was purified by 75% ammonium sulfate fractionation, QAE-Sephadex anion and SP-Sephadex cation exchange column chromatography and Sephadex G-100 gel filtration. The specific activity of the purified enByme was 233.9 unit/mg protein and the yield of enzyme was 3.8%. The homogeneity of the purified enzyme was confirmed by polyacrylamide gel electrophoresis. Molecular mass of the enzyme was estimated about 21,500 Da by SDS-polyacrylamide get electrophoresis and gel chromatography. The optimum temperature and pH for the enzyme activity were $40^{\circ}C$ and 9.0, respectively. The enzyme was stable in a pH range of 5.0 to 12.0, and 60% of its activity was lost on heat treatment at $50^{\circ}C$ for 20 min. The activity of the purified enzyme was inhibited by the presence of $Fe^{2+},\;Ag^{2+},\;Cu6{2+}$, iodoacetate, ethylene diamine tetraacetic acid (EDTA), and trans-1,2-diaminocycloheane-N,N,N',N'-tetraacetic acid (CDTA). The results indicates that the enzyme requires a metal ion for its enzymatic activity.

With an overwhelming majority, the United Nations Convention on the Law of the Sea(hereinafter “the UNCLOS”) was adopted in April 1982 in New York. Nevertheless the its future loomed uncertain until the late 1980s as advanced industrialized States were not ready to ratify it because of their dissatisfaction with the Part XI seabed regime. It is not until July 1994 when the Part XI Implementation Agreement was adopted through the informal consultations convened by the Secretary-General of the United Nations that the concerns of advanced industrialize States were addressed. Fisheries resources being rapidly depleted in the high seas was another issue which emerged after the adoption of the UNCLOS. This issue was dealt with through the adoption of the UN Fish Stocks Agreement which provides a basis for sustainable fisheries in the high seas. The UNCLOS entered into force in November 1994, the number of its States Parties staying at 168 including the European Union. States are primarily responsible for implementing the UNCLOS, while the International Seabed Authority, the International Tribunal for the Law of the Sea and the Commission on the Limits of the Continental Shelf created by the UNCLOS carry out their respective functions assigned to each of them under it. To date the Authority has drawn up three sets of exploration and prospecting regulations on deep seabed minerals, and one set of exploitation regulations is under preparation. The Tribunal has dealt with the disputes concerning the interpretation and application of the UNCLOS brought before it by the States Parties. Likewise, the annex VII arbitral tribunals and the International Court of Justice have handled the disputes concerning the interpretation and application of the UNCLOS submitted to them. The Commission has so far received 96 submissions and issued 35 recommendations. Over the last four decades the UNCLOS has played a critical role in establishing the rule of law in the oceans, thus making a great contribution to the promotion of international peace and security. Since 2015 the United Nations has been working to draw up an international legally binding instrument under the UNCLOS on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction. The International Law Commission is considering the potential consequences of sea-level rise caused by the global warming such as moving landward of coastlines and disappearing islands. The International Maritime Organization is dealing with the issues relating to maritime autonomous surface ships(MASS) which are to be on service by virtue of the advancement in technology. In the 1990s the international community adopted two implementation agreements under the UNCOLS. In light of this precedent, the international community is expected to find appropriate solutions, under the UNCLOS, to the conservation and use of marine biodiversity beyond areas of national jurisdiction, the consequences of sea-level rise and the issues relating to maritime autonomous surface ships.
