Purpose: The purpose of this study was to assess the needs of RN-BSN students concerning the RN-BSN curriculum and make suggestions for improvement in the curriculum based on the needs of the students. Method: A descriptive survey study was used. Data were collected from 707 RN-BSN senior students in 21 universities. The research instrument, which was developed after in-depth interviews with 13 RN-BSN students, consisted of 10 curriculum objectives, 34 cultural courses, 48 major courses, three questions on clinical practicum, and teaching methods for 5 required courses. Result: The curriculum objectives selected by the RN-BSN students were problem solving, clinical applicability, critical thinking, creative thinking, and decision making. They wanted cultural courses such as English, understanding of human behavior, social welfare, women's studies, psychology, nutrition science, leadership, recreation, computer applications, exercise and health. They wanted major courses to include the nursing process, nursing research, health assessment, advanced adult nursing, infection control, spiritual/hospice nursing, and nursing of cancer patients. They responded that a clinical practicum was not necessary. They wanted to experience various teaching methods according to particular characteristics of subject being taught. Conclusion: This study suggests some recommendation for improvement of the curriculum based on the needs of RN-BSN students.

The mitochondrial genome of domesticated silkworm (Bombyx mori) was mapped with five restriction endonucleases (BamHI, EcoRI, HindIII, PstI and XbaI), the entire genome was cloned with HindIII and EcoRI. From the end sequencing results of 5$^1$and 3$^1$region for full genome set of eleven mitochondrial clones, the seven mitochondrial genes (NADH dehydrogenase 6, ATPase 6, ATPase 8, tRN $A^{Lys}$, tRN $A^{Asp}$, tRN $A^{Thr}$ and tRN $A^{Phe}$ of mori were identified on the basis of their nucleotide sequence homology. The nucleotide composition of NADH dehydrogenase 6 was heavily biased towards adenine and thymine, which accounted for 87.76%. On basis of the sequence similarity with published tRNA genes from six insect species, the tRN $A^{Lys}$, tRN $A^{Asp}$ and tRN $A^{Thr}$ were showed stable canonical clover-leaf tRNA structures with acceptible anticodons. However, both the DHU and T$\psi$C arms of tRN $A^{Phe}$ could not form any stable stem-loop structure. The two overlapping gene pairs (tRN $A^{Lys}$ -tRN $A^{ASP}$ and ATPase8-ATPase6) were found from our sequencing results. The genes are encoded on the same strad. ATPase8 and ATPase6 overlaps (ATGATAA) which are a single example of overlapping events between abutted protein-coding genes are common, and there is evidence that the two proteins are transcribed from a single bicistronic message by initiation at 5$^1$terminal start site for ATPase8 and at an internal start site for ATPase6. Ultimately, this result will provide assistance in designing oligo-nucleotides for PCR amplification, and sequencing the specific mitochondrial genes for phylogenetics of geographic races, genetically improved silkworm strains and wild silkworm (mandarina) which is estimated as ancestal of domesticated silkworm.sticated silkworm.

The purpose of this survey study is to guide the direction of the RN-BSN program in Korea by analyzing (1) the philosophy and objectives (2) curriculum (3) and appraisal method, achievement test and self-directed learning. In this study, subjects consisted of 20 department of nursing in University and 20 RN-BSN programs in Korea. The Survey was conducted from September 1999 through May 2000 by mail and FAX. 1) Educational philosophy and objectives of 5 RN-BSN programs have curricular based philosophy. Most popular philosophies were revealed that nursing is oriented role function, human relation, and integrated application. 9 RN-BSN programs have curricular based objectives. There are including of knowledge, applying the new technology, under-standing of human being family community, application of nursing process, leadership, nursing ethics, and participation in research. 2) In RN-BSN programs, total mean credits through general college courses for earning the degree of BSN is 21.5 and total mean credits through the nursing area for earning the degree of BSN is 71.4. In RN-BSN programs, total mean credits through clinical practice for earning the degree of BSN is 5.94. 25.00 of mean credits was earned through achievement test(6.00~37.00). Therefore, this research suggests some recommendation for the development of curriculum of RN-BSN program that was required to do some alterations. And the various and other methods of earning credit should be developed. That is, the students will earn credits, accredited examination of University, advanced placement examination, case study, self-report, self-directed learning and achievement tests, portfolio review session and so on. And the RN-BSN courses are delivered to many areas by teleconferencing system, computer network(EdNet or Internet etc), CD-ROM Title, VOD (video on demand) and other methods.

This descriptive survey design study was aimed to investigate nursing students' perspectives of nursing care. One hundred seventeen junior or senior students in BSN program and 131 junior or senior students in RN-BSN program at K University were compared and contrasted in terms of their perspectives on nursing care. Using the instrument developed by Cho Kyoul-Ja and Song Mi-Ryung(1997), the data were collected from April 1st to April 30th in 2003. The findings of the research are as follows. 1. The average perspective score of the RN-BSN students was higher than that of the BSN students. 2. The RN-BSN students reported higher scores than those of the BSN students in perspectives on personal qualification and meanings, and perspectives on scope and function of their nursing care. However, there was no significant difference between the groups in overall nature and domains of nursing care. 3. In terms of the participants' demographic backgrounds such as, grades in the program, religion, history of hospitalization, there was no significant difference between the BSN and RN-BSN groups. 4. No significant difference was found within the RN-BSN group in terms of their nursing perspectives associated with the years of clinical experience. In conclusion, the score of nursing perspectives in RN-BSN student group was higher than that of the BSN students. No other differences were found in this study. The higher nursing perspective score in RN-BSN group is attributed to their clinical experience. Thus, it is suggested that philosophy and value of nursing should be taught early in nursing program in order for nursing students to obtain proper points of views on nursing care. In addition, nursing philosophy, holistic view, and humanistic values should be stressed in continuing education for clinical nurses in order for them to maintain dignitary perspectives in nursing care.

지금까지 인공지능의 한 분야인 딥러닝 방법은 구조화되지 않은 데이터로부터 문제를 해결하는 놀라울만한 성과를 이루어왔지만, 인간처럼 여러 상황들을 종합적으로 판단, 그것들의 연관성을 추론하고, 그 다음 상황을 예측하는 수준의 지능을 갖는데 도달하지 못하였다. 최근 발표된 복잡한 관계 추론을 수행하는 심층 신경망은 인공지능이 인간의 핵심 지적 능력인 관계 추론을 보유할 수 있다는 것을 증명하였다. 본 논문에서는 관계 추론 심층 신경망 중에서 Relation Networks (RN)의 성능을 분석 및 관찰해 보고자 Sort-of-CLEVR 데이터 셋을 사용한 시각적 질의응답과 bAbI task를 사용한 텍스트 기반 질의응답 두 유형의 RN 기반 심층 신경망 모델을 구축하여 baseline 모델과의 비교를 통한 성능검증을 하였다. 또한 모델의 성능을 극대화하기 위하여 하이퍼 파라미터 튜닝 등 다양각도의 성능개선 실험으로 관계 추론을 위한 RN 기반 심층 신경망 모델의 성능개선 방법을 제안하였다. 제안한 성능개선 방법은 시각적 질의응답 모델과 텍스트 기반 질의응답 모델에 적용하여 그 효과를 검증하였고, 기존의 RN 모델에서 사용해보지 않았던 Dialog-based LL 데이터 셋을 사용하여 새로운 도메인에서의 제안한 성능개선 방법의 효과를 다시 한 번 검증하였다. 실험 결과 두 유형의 RN 모델 모두에서 초기 학습률이 모델의 성능을 결정하는 핵심 요인임을 알 수 있었고, 제안한 random search 방법에 의해 찾은 최적의 초기 학습률 설정이 모델의 성능을 최고 99.8%까지 향상 시킬 수 있다는 것을 확인하였다.

The gaseous $^{222}Rn$ concentration at the level of clouds was estimated by using the wet scavenging model of its decay products with the observed data of environmental radiation at the ground. And the origin of the $^{222}Rn$ was also discussed. The estimation was done for a precipitation event on Dec. 26-27, 2003, when a large increase of the radiation was observed in Tokai-mura in Ibaraki, Japan. From a backward trajectory analysis, the origin of $^{222}Rn$ atoms for that event was traced back to the northeastern part of China, and it was expected that the large amount of $^{222}Rn$ emitted in the northeastern part of China was transported to Tokai-mura by the Eurasian continental air mass.

Diffusion is a crucial mechanism that regulates the migration of radioactive nuclides. In this study, an innovative numerical method was developed to simultaneously calculate the diffusion coefficient of both parent and, afterward, series daughter nuclides in a sequentially reactive through-diffusion model. Two constructed scenarios, a serial reaction (RN_1 ${\rightarrow}$ RN_2 ${\rightarrow}$ RN_3) and a parallel reaction (RN_1 ${\rightarrow}$ RN_2A + RN_2B), were proposed and calculated for verification. First, the accuracy of the proposed three-member reaction equations was validated using several default numerical experiments. Second, by applying the validated numerical experimental concentration variation data, the as-determined diffusion coefficient of the product nuclide was observed to be identical to the default data. The results demonstrate the validity of the proposed method. The significance of the proposed numerical method will be particularly powerful in determining the diffusion coefficients of systems with extremely thin specimens, long periods of diffusion time, and parent nuclides with fast decay constants.
