The authors report two cases of familial hemifacial spasm according to the clinical and three dimensional shortrange magnetic resonance angiography(3D-SRMRA) findings. In the family of the first case, there were five patient's with acquired hemifacial spasm in successive generations. Three male and two female patients in successive generations of the same family developed acquired hemifacial spasm. Four patients were on the left side and one was on the right side. In the family of the second case, there were three patient's with acquired hemifacial spasm in successive generations. Two brothers developed left-sided hemifacial spasm. 3D-SRMRA finding of the probands demonstrated that both anterior inferior cerebellar artery in first case and anterior inferior cerebellar artery & vertebral artery in second case offend the 7th cranial nerve respectively. The presence of familial clustering of these rare disorders suggest an underlying genetic predisposition. All family pedigrees suggest that a pattern of autosomal-dominant inheritance with partial penetrance.

Effective population size ($N_e$) is an important measure to understand population structure and genetic variability in animal species. The objective of this study was to estimate $N_e$ in Sapsaree dogs using the information of rate of inbreeding and genomic data that were obtained from pedigree and the Illumina CanineSNP20 (20K) and CanineHD (170K) beadchips, respectively. Three SNP panels, i.e. Sap134 (20K), Sap60 (170K), and Sap183 (the combined panel from the 20K and 170K), were used to genotype 134, 60, and 183 animal samples, respectively. The $N_e$ estimates based on inbreeding rate ranged from 16 to 51 about five to 13 generations ago. With the use of SNP genotypes, two methods were applied for $N_e$ estimation, i.e. pair-wise $r^2$ values using a simple expectation of distance and $r^2$ values under a non-linear regression with respective distances assuming a finite population size. The average pair-wise $N_e$ estimates across generations using the pairs of SNPs that were located within 5 Mb in the Sap134, Sap60, and Sap183 panels, were 1,486, 1,025 and 1,293, respectively. Under the non-linear regression method, the average $N_e$ estimates were 1,601, 528, and 1,129 for the respective panels. Also, the point estimates of past $N_e$ at 5, 20, and 50 generations ago ranged between 64 to 75, 245 to 286, and 573 to 646, respectively, indicating a significant $N_e$ reduction in the last several generations. These results suggest a strong necessity for minimizing inbreeding through the application of genomic selection or other breeding strategies to increase $N_e$, so as to maintain genetic variation and to avoid future bottlenecks in the Sapsaree population.

This paper studies a partial coordination situation where a set of countries coordinate their monetary policies among themselves;while the rest of the world choose their policies independently. Using a three-country orewlapping generations model, it is shown that nash partial-coordination equilibrium does not exist. This paper also studies the partial coordination under unanticipated productivity shocks.

이 논문의 목적은 한국사회의 세대갈등을 권력갈등, 이념갈등, 문화갈등으로 구분하여 갈등 형성의 배경과 실태를 분석하고 그 함의를 논의하는 데 있다. 실태 분석을 위하여 관공서의 집합 자료와 경험적 연구결과들이 활용되었다. 우선, 세대간 권력갈등의 핵심은 권력 이양시기를 둘러싼 충돌에 있다. 세대간 권력갈등을 의회 권력에 국한시켜 볼 때, 정권교체기의 이념적 지향의 부침과는 무관하게 젊은 의원들의 비율이 꾸준히 증가하는 저(低) 연령화 추세가 지속되고 있었다. 이러한 세대교체 추세는 당분간 다른 영역에서도 유지될 것으로 보인다. 다음으로, 세대간 이념갈등은 2002년 대선 전 후 극대화되었으나 04년 총선 이래 점차 완화되었다. 그러나 조건의 변화에 따라 일정한 계기가 주어지면 다시 활성화될 수 있을 것이다. 마지막으로, 문화 격차의 견지에서 볼 때 세대균열의 깊은 골은 대략 출생시점 1970년경을 중심으로 형성되었다. 문화갈등의 축을 성장주의 대 소비주의, 집단주의 대 개인주의, 권위주의 대 탈권위주의로 설정하여 갈등의 배경과 실태를 검토했다. 세 유형의 갈등 중 문화갈등의 역기능에 주목해야 한다. 세대간 문화격차 확대는 상호 의사소통을 방해하며 상호 교류와 공동 활동 기피라는 결과를 낳을 수 있기 때문이다. 문화갈등 완화를 위해, 사회 제 부문의 부조리와 비리 척결 그리고 세대 통합 프로그램을 활용하는 방안 등이 제시되었다.

Purpose - This study aims to examine differences in donation behavior as surrogates of prosocial consumption behavior among three generation types. Further, it attempts to examine the moderator roles that affect donation behavior influenced by the difference in generations. Research design, data, and methodology - This study used the statistical ANOVA technique to examine generational difference. Surveys were structured differently by ages, as 20th, 30th, 40th, 50th, 60th, and 70th to classify generations into each group. A survey to measure the psychological distance was performed to identify whether the respondents intended to donate to a domestic or overseas target. Results - First, subjective judgment of psychological distance has no effect on objective donation behavior. Second, though the result of the relationship with moral identity is not statistically significant, it provides evidence that a higher moral identity level possesses more donation behavior. Further, groups with higher symbolization tend to donate more than the others. This was especially evident among the young and baby boomer generation. Conclusion - This empirical study suggests that marketers need to differentiate the market segment of the baby-boomer generation with high purchasing power of prosocial consumption.

사냑간섭계 원리를 이용한 자이로는 연구의 계기가 된 발명 또는 연구시기에 따라서 크게 3세대로 구분되어질 수 있다. 사냑간섭계 원리를 이용한 첫 번째 자이로인 링레이저 자이로는 레이저의 발명에 의해서 1960년대 부터 연구되어 왔으며, 사냑간섭계 원리를 이용한 2세대 자이로인 광섬유 자이로는 통신용 광섬유의 발명에 의해서 1970년대부터 연구되어 왔다. 원자의 파동성이 입증된 1990년대 후반에는 차기세대 자이로 개발을 위한 원자간섭계 연구가 시작되었다. 본 논문은 이러한 세 분류의 사냑간섭계 원리를 이용한 자이로의 동작원리, 응용분야, 그리고 발전전망에 대하여 논의하였다.

This paper investigates differences between generations in the vowel system of the Daegu dialect in terms of F1 and F2 of the monophthongs. Three different groups of subjects participated in the present study: 20 female native speakers of the Daegu dialect(10 in their 20's and 10 in their 40's), and 10 female native speakers of the Seoul dialect as a control group. It has been assumed that the Daegu dialect has six vowels. However, younger generation appears to have 7 vowels different from older generation. The result of the present study showed that the Daegu dialect has different vowel systems between generations: for 40's have six vowels and 20's have seven vowels. These differences seems to be attributed to the influence of the Seoul dialect.

Here, we report a computer program written in Python, which phases SNP genotypes and infers inherited deletions based on the pattern of Mendelian inheritance within a trio pedigree. When tiered trio genotypes that encompass three generations are available, it narrows a recombination event down to a region between two consecutive heterozygous markers. In addition, the phase information that is inferred from the upper trio that is formed by one of the parents and grandparents can be propagated to phase the genotypes of the lower trio that is formed by the parents and an offspring.
