In this paper, we introduce the concepts of ([r, s], [t, u])-interval-valued intuitionistic fuzzy generalized preclosed sets and ([r, s], [t, u])-interval-valued intuitionistic fuzzy generalized preopen sets in the interval-valued intuitionistic smooth topological space and ([r, s], [t, u])-interval-valued intuitionistic fuzzy generalized pre-continuous mappings and then investigate some of their properties.

We introduce the concepts of double (r, s)(u, v)-preopen sets, double (r, s)(u, v)-preclosed sets and double pairwise (r, s)(u, v)-precontinuous mappings in double bitopological spaces and investigate some of their characteristic properties.

In this paper we establish some recurrence relations satisfied by quotient moments of upper record values from the Pareto distribution. Let ｛$X_n,n\qeq1$｝be a sequence of independent and identically distributed random variables with a common continuous distribution function(cdf) F($chi$) and probability density function(pdf) f($chi$). Let $Y_n\;=\;mas{X_1,X_2,...,X_n}$ for $ngeq1$. We say $X_{j}$ is an upper record value of {$X_{n},n\geq1$}, if $Y_{j}$＞$Y_{j-1}$,j＞1. The indices at which the upper record values occur are given by the record times ${u( n)}n,\geq1$, where u(n) = min{j｜j ＞u(n-l), $X_{j}$＞$X_{u(n-1)}$,n\qeq2$ and u(l) = 1. Suppose $X{\epsilon}PAR(\frac{1}{\beta},\frac{1}{\beta}$ then E$(\frac{{X^\tau}}_{u(m)}}{{X^{s+1}}_{u(n)})\;=\;\frac{1}{s}E$ E$(\frac{{X^\tau}}_{u(m)}{{X^s}_{u(n-1)}})$ - $\frac{(1+\betas)}{s}E(\frac{{X^\tau}_{u(m)}}{{X^s}_{u(n)}}$ and E$(\frac{{X^{\tau+1}}_{u(m)}}{{X^s}_{u(n)}})$ = $\frac{1}{(r+1)\beta}$ [E$(\frac{{X^{\tau+1}}}_u(m)}{{X^s}_{u(n-1)}})$ - E$(\frac{{X^{\tau+1}}_u(m)}}{{X^s}_{u(n-1)}})$ - (r+1)E$(\frac{{X^\tau}_{u(m)}}{{X^s}_{u(n)}})$]

In 1977, the United States enacted the Magnuson Fishery Conservation and Management Act (MFCMA), which established U.S. Fisheries Conservation Zone (FCZ). The MFCMA grants preference to U.S. harvesters over foreign fleets in the U.S. FCZ. At present, the large stocks of groundfish in the U.S. FCZ off the Alaska coast have been under-utilized in the U.S. domestic market and the fisheries for these groundfish are dominated by foreign fleets. Hence, expected benefits from replacing foreign fisheries by domestic fleets will accrue to the U.S. fishery only by exporting the increased U.S. products to foreign countries. U.S. exports may be dependent on the price levels in the foreign markets raised by the reduced foreign catch from U,S. waters. In this paper, Japanese demand models for Alaska groundfish were estimated. The derived coefficient from the estimated models suggest that a decrease in the Japanese landings from the U.S. FCZ by a thousand metric tons will increase pollock price by 0.017 Yen/kg, cod price by 0.351 Yen/kg, flatfish by 1.074 Yen/kg, and ocean perch by 1.347 Yen/kg in the Japanese market. These results based on percentage would increase 19 percent for pollock price, 11 percent for cod price, 40 percent for flatfish, and 2 percent for ocean perch price.

1986년부터 1994년까지 주로 우리나라의 서해와 남해 연안에서 채집된 한국산 통구멍과 어류에 대하여 분류학적 위치와 이들의 형태적 특징에 대하여 재검사하였다. 그 결과 한국산 통구멍과 어류로는 3층 6종으로 확인되었는데 통구멍층 Uranoscopus에는 얼룩통구멍 U. japonicus, 통구멍이 U. bicinctus, 민통구멍 U. chinensis, 비늘통구멍 U. tosae 등의 4종이고, 푸렁통구멍층 Gnathagnus에는 푸렁통구멍 G. elongatus 1종, 큰무늬통구멍층 Ichthyscopus에는 큰무늬통구멍 I. lebeck sannio 1종 등 모두 6종이다. 이들 어류의 분류학적 중요 형태 형질로는 체표의 구점, 전새개골 하부의 가시 수, 호흡판의 형태, 비공판의 형태, 입술돌기의 발달 상태 등이었다. 한편 지금까지 기재되어 온 U. flavipinnis는 U. chinensis의 synonym으로 정리되었다. 우리나라의 서해와 남해에 주로 많이 분포하고 있는 종은 Uranoscopus japonicus와 Gnathagnus elongatus이고, 남해에는 U. bicinctus, U. chinensis, U. tosae 등이며 특히 Ichthyscopus lebeck sannio는 주로 제주도 부근 해역에서 출현하고 있다.

Korean businesses, and their legal representatives, have observed the improvements of enforcement of commercial judgments through arbitration over traditional collections litigation in U.S. Courts-due to quicker proceedings, exceptional cost savings and more predictable outcomes-in attaching assets within U.S. jurisdictions. But how are the 2016 interim measures implemented by the Arbitration Act of Korea utilized to avoid jurisdictional and procedure pitfalls of enforcement proceedings in the Federal Courts of the United States? Authors examine the necessary prerequisites of the U.S. Federal Arbitration Act as adopted through the New York Convention, to which Korea and the U.S. are signatories, as distinguished from the Panama Convention. Five common U.S. arbitration institutions address U.S. "domestic" disputes, preempting U.S. state law arbitrations, while this article focuses on U.S. enforcement of "international" arbitration awards. Seeking U.S. recognition and enforcement of Korean arbitral awards necessitates avoiding common defenses involving due process, public policy or documentary formality challenges. Provisional and conservatory injunctive relief measures are explored. A variety of U.S. cases involving Korean litigants are examined to illustrate the legal challenges involving non?domestic arbitral awards, foreign arbitral awards and injunctive relief. Suggestions aimed toward further research are focused on typical Korean business needs such as motions to confirm foreign arbitration awards, enforce such awards or motions to compel arbitration.

Because Korea has the excellent informational technology, it was expected to be able to improve the accessibility to healthcare and compete with other nations in excellence through u-Healthcare. But we can't complete the excellent u-Healthcare because of the law to be able to use only the tele-counselling between doctor to doctor or doctor to nurse. First of all, we must complete the law to be able to use the improved u-Health containing of telemedicine between doctor to patient. Though other factors, the procurement of safe IT, the credibility to healthcare service provider containing of nutritionist and occupational therapist etc. are prepared for erecting u-Healthcare, we can get the final and decisive u-Health policy only by means of Law for supporting u-Healthcare's Activation. The important sections of Law for supporting u-Healthcare's Activation are as follows. Sec. 4 The Minister for Health, Welfare and Family Affairs and the dean of associated administrative division have to erect the combined plan for u-Healthcare's Activation. Sec. 11 Government and local autonomous entity can support the facility and equipment to be necessitated for using u-Healthcare to improve the medical accessibility of person in the region with poor medicine. Sec. 13 Doctor can support other doctor's medical action through IT and if there are not medical risk, doctor can give medical act directly to the special patients. Sec. 21 If pharmaceuticals is necessitated in u-Healthcare, remote doctor has to send the patient the electronic prescription and the pharmaceutist to receive the electronic prescription has to delivery the pharmaceuticals in accordance with patient's demand.
