The photohydration of 1-(m-nitrophenyl)-5, 5-dimethyl-1, 3-hexadiyne (m-NDHD) affords allenyl ketone compound (1) via triplet excited state which is converted into $\beta$-dicarbonyl compound (2) through thermal hydration. The allenyl ketone is formed by the synchronous addition of water with protonation at C$_1$ indicating that m-NDHD has the reverse polarization and greater electron withdrawing effect in the triplet excited state in comparison with p-NDHD.

In this paper, we investigate the methods to improve the position accuracy using DGNSS(Differential Global Navigation Satellite System). Then we configure the real-time DGNSS environment with use of GPS and MSAS as SBAS(Satellite Based Augmentation System) currently being in service by Japan. And we verify the improvement of position accuracy and the continuity of GPS correction data through the realtime DGNSS test in Joongang line, Kyungbu line, Honam line.

In this paper, we prove the generalized Hyers-Ulam stability of the additive functional inequality $${\parallel}f(x-y)+f(y-z)+f(z){\parallel}{\leq}{\parallel}f(x){\parallel}$$ in Banach spaces.

투과전자현미경(TEM)의 관찰을 위한 반도체 시료의 박편제작기술에 대하여 언급하였다. 전자선을 투과할 수 있는 얇은 두께의 시편을 제작하는 일은 금속이나 생물학적인 재료에 비하여 반도체의 경우 많은 어려움이 따르며 특히 잘 부서지기 쉬운 특성 때문에 취급에 많은 주의를 요한다. 반도체를 대상으로 하여 일반적으로 사용되는 박편 제작기술에 대해 그 특성과 장단점 등을 조사하였다.

This paper proposes a new method to improve signal characteristics at branches frequently met in system-level routing. We also introduce the numerical formula which can estimate the time delay due to branches and the simple design guideline for system-level routing. Finally, we propose the routing method which can eliminate the signal reflection for the case of one driver and two receivers (multi-drop topology).

Koreans have been interested in the North Pacific fisheries since the exploratory fishing was carried out by R/V Baek-Kyung of Pusan Fisheries College in 1966. Although the salmon fishing was interrupted by some countries, Korean trawlers are venturing in the North Pacific Ocean for catching demersal fishes. The trawl fishery in the region raises some problems. i. e. the conflict with the coastal or nearshore fishery, low fish price, etc. This paper concerns with the plan for the settlement of these problems..

Parenchymal pulmonary endometriosis is the likely cause in patients with hemoptysis, dyspnea, or chest pain during menstruation. Embolization of endometrial tissue from the uterus to the lungs via the pulmonary arteries has been proposed for the mechanism of the development of parenchymal pulmonary endometriosis. This is a report of a woman with catamenial hemoptysis which was responded successfully to danazol therapy; however, hemoptysis resumed after cessation of therapy. The patient was subsequently treated with danazol again because she refused surgical treatments.
