  • Radio occultation technique has been used in planetary science to obtain reliable and accurate temperature profiles of the other planets' atmosphere for decades. It relies on the fact that radio waves are bent and delayed due to the gradient of atmospheric refractivity along-ray-path. With the advent of Global Positioning System (GPS), it becomes possible to retrieve the refractivity and temperature profiles of the Earth's atmosphere from the occultation data. We have developed a retrieval algorithm and compared the results of our algorithm with the data of CHAMP to verify the accuracy of our algorithm is good enough. In our algorithm, there are some smoothing steps when retrieving. We analysis the data of FORMOSAT-3 and compare the results with and without smoothing and the results of TACC to see is there any phenomenon deleted after smoothing.

  • Objective: The aim of the present study was to identify genetic variants based on RNA-seq data, obtained via transcriptome sequencing of muscle tissue of pigs differing in muscle histological structure, and to verify the variants' effect on histological microstructure and production traits in a larger pig population. Methods: RNA-seq data was used to identify the panel of single nucleotide polymorphisms (SNPs) significantly related with percentage and diameter of each fiber type (I, IIA, IIB). Detected polymorphisms were mapped to quantitative trait loci (QTLs) regions. Next, the association study was performed on 944 animals representing five breeds (Landrace, Large White, Pietrain, Duroc, and native Puławska breed) in order to evaluate the relationship of selected SNPs and histological characteristics, meat quality and carcasses traits. Results: Mapping of detected genetic variants to QTL regions showed that chromosome 14 was the most overrepresented with the identification of four QTLs related to percentage of fiber types I and IIA. The association study performed on a 293 longissimus muscle samples confirmed a significant positive effect of transforming acidic coiled-coil-containing protein 2 (TACC2) polymorphisms on fiber diameter, while SNP within forkhead box O1 (FOXO1) locus was associated with decrease of diameter of fiber types IIA and IIB. Moreover, subsequent general linear model analysis showed significant relationship of FOXO1, delta 4-desaturase, sphingolipid 1 (DEGS1), and troponin T2 (TNNT2) genes with loin 'eye' area, FOXO1 with loin weight, as well as FOXO1 and TACC2 with lean meat percentage. Furthermore, the intramuscular fat content was positively associated (p<0.01) with occurrence of polymorphisms within DEGS1, TNNT2 genes and negatively with occurrence of TACC2 polymorphism. Conclusion: This study's results indicate that the SNP calling analysis based on RNA-seq data can be used to search candidate genes and establish the genetic basis of phenotypic traits. The presented results can be used for future studies evaluating the use of selected SNPs as genetic markers related to muscle histological profile and production traits in pig breeding.

  • This study is aimed at construction of a translator for a functional programming language. For this goal we define a functional programming language which has lazy semantics and develop a translator for it. The execution model selected is the G-machine-based combinator graph reduction. The translator is composed of 4 phases and translates a source program to a C program. The first phase of the translator translates a source program to a enriched lambda- calculus graph, the second phase transforms a lambda-calculus graph into supercombinators, the third phase translates supercombiantors to a G program and the last phase translates the G program to a C program. The final result of the translator, a C program, is compiled to an executable program by C compiler. The translator is implemented in C using compiler development tools such as TACC and Lex, under the UNIX environments. In this paper we present the design and implementation techniques for developing the translator and show results by executing some test problems.

  • 이 논문은 2002년도 부경대학교 수산경영학과 박사학위논문(A Study on Institutional Arrangements for Quota-Based Management : The Case of China's Marine Capture Fisheries)의 일부이다. 이 논문의 기본목적은 취터제에 기초한 중국의 어업관리를 위한 제도적인 틀을 세우고자 하는데 있으며, 이런 목적을 달성하기에 위해 이 논문은 다음과 같이 구성하여 연구를 진행시켰다. 제1장은 연구목적과 문제의 제기에 이어 제2장에서는 중국 해양어업의 개발과 이에 따른 문제점을 분석하였으며, 여기에서 궈터제에 기초한 어업관리정책의 제도적 제안을 함과 동시에, 제3장에서는 중국 해양어업의 현실과 중국 사회의 일반적인 현상을 분석하여 제4장을 통해 쿼터제에 기초한 중국의 어업관리를 위한 제도적 프레임러크를 제안하였다. 마지막으로 본 논문을 요약하고 향후 계속되어야 할 연구과제를 제시하였다. 본 논문의 중요한 연구 결과는 다음과 같다. 현재 중국 수산업의 관리체제는 질적 규제 중심 관리제도, 그리고 정부 주도하의 어업관리 과정으로 특징지을 수 있다. 이러한 명령과 통제 (command-and-control) 방식의 전통적인 중국어업 관리제도로서는 어업인들에게 있어서 자원 보존에 대한 동기와 제도에 대한 수용성을 약화시키며, 정부 규제를 오히려 무시하게 되는 결과를 초래한다. 결과적으로 현형 중국의 어업관리제도는 어업인에게 있어서 자원 보전에 대한 유인을 약화시키고 단기적인 수익을 극대화하도록 유도하는 맹점을 지니므로 인해 더 이상 지속적인 어업성립의 보장을 할 수 없다는 점을 지적할 수 있다. 중국정부는 이러한 어업관리제도의 불완전성을 인식하여 2000년 10월 31일에 1986년 에 제정된 수산업법을 개정하게 되었으며, 새로운 중국의 수산업법은 어업 허가제도와 함께 할당량제에 기초한 어업관리제도를 국가가 운영하는 것으로 특징지을 수 있다. 그러나 아직까지 중국은 할당제에 근거한 어업관리제도를 미실시중에 있으며, 그 내용도 애매모호한 점을 많이 가지고 있다. 또한 중국의 절대적 어획량은 현재 논란의 여지로 남아있고, 거대 어업 인구의 근본적인 요구와 중국 어선의 국제적인 경쟁력, 그리고 유어(遊漁)에 대한 사회적 요구 등도 중국의 수산정책이 채결해야 할 과제이다. 위에서 고찰한 내용을 기초로 하여 우리는 중국의 쿼터제에 기초한 어업관리에 대해 다음과 같은 몇 가지를 제안한다. 중국 연근해어업에 있어서 할당제 모형에 참가하는 어업 참여자들의 유형은 세 가지로 구분할 수 있다. 첫째는 어촌에 거주하면서 생존수단으로 소규모 어업에 종사하는 경우이고, 둘째는 유어어업의 경우이며, 셋째는 상업적 목적으로 어업에 종사하는 집단으로 나눌 수 있다. 이러한 세 집단을 하나의 제도의 틀로 통합하기 위해서는 국가의 총허용어획량(TAC)을 총 어촌 허용어획량(TAIVCs)과 총 허용 유어 어획량(TARCs) 및 총허용 상업적 어획량 (TACCs)의 세부문으로 나눌 것을 제안한다. 그리하여 다시 TAFVCs와 TARCs, 그리고 TACCs는 어촌별 어획량(ITCQs), 개별 유어 회사별 어획량(IRCQs), 그리고 양도 가능한 개별 상업적 어획량(ITCQs)으로 나누어 관리하도록 한다. 이와 같이 중국의 국가 총허용어획량(TAC)을 IFVQs와 IRCQs, 그리고 ITQCQs의 세부문으로 구분하여 할당하고, 여기에 기초하여 어업을 관리하는 것은 중국에 있어서 사회적 형평성과 경제적 효율성과의 상충관계를 고려하여 고안된 것으로, 중국에 있어서 수산업을 통한 경제적 및 사회적 효과를 동시에 기대할 수 있을 것이다.

  • This study was carried out to clarify the effect of addition of perilla leaf powder (PLP) and carcass grade on the quality and palatability of pork sausage. The chemical composition, pH, calorie, water holding capacity, surface color, textural properties and amino acid composition of the samples were determined, and sensory characteristics were evaluated. Moisture and crude ash were not different among sausage of four type. Crude fat of grade B sausage was higher than that of grade E sausage, and grade B sausage added PLP was higher than grade B sausage without PLP. Crude Protein of grade E sausage was higher than that of grade B sausage. The pH of grade E sausage added PLP was highest, and calorie of grade B sausage without PLP was highest among sausage of four type. Water holding capacity of grade B added and free PLP was significantly higher than grade I sausage. The residual nitrite of sausage added PLP was significantly lower than sausage without PLP. In case of Hunter's $L^{*}$, grade B sausage and free PLP sausage were significantly higher than grade E sausage and sausage added PLP, respectively. In case of Hunter' $a^{*}$, grade E sausage and free PLP sausage were significantly higher than grade B sausage and sausage added PLP. Hunter's $b^{*}$ of sausage added PLP was higher than that of free PLP sausage. Textural properties, hardness, springiness, cohesiveness and chewiness were significantly different among sausage of four type, but gumminess of grade E added PLP was lowest among sausage of four type. Total amino acid was not significantly different among sausage of four type. Sensory color and texture of grade B sausage were superior to grade I sausage, palatability of free PLP sausage was superior.sage was superior.
