기존의 협업필터링 추천시스템 연구는 상품에 대한 고객의 평점(rating)이나 구매 여부 데이터로부터 하나의 프로파일을 생성하고 이를 기반으로 추천 성능을 향상시킬 수 있는 새로운 알고리즘을 개발하는 위주로 진행되어 왔다. 그러나 빅데이터 환경이 도래하면서 기업이 수집할 수 있는 고객 데이터가 풍부해지고 다양해짐에 따라, 보다 정확하게 고객의 선호도나 행태를 파악하는 것이 가능하게 되었고 이러한 데이터, 즉 퍼스널 빅데이터(personal big data)를 추천시스템에 활용하는 연구의 필요성이 대두되고 있다. 본 연구에서는 마케팅의 시장세분화 이론에 근거하여 퍼스널 빅데이터로부터 고객의 선호도나 행태를 다양한 관점에서 표현할 수 있는 5종의 다중 프로파일(multimodal profile)을 개발하고, 이를 활용하여 협업필터링 추천시스템의 성능을 개선하고자 한다. 제안하는 5종의 다중 프로파일은 프로파일 통합 유사도, 개별 프로파일 유사도 평균, 개별 프로파일 유사도 가중 평균이라는 세 가지 앙상블 기법을 통해 협업필터링의 이웃(neighborhood) 탐색과정에 적용된다. 실제 퍼스널 빅데이터에 본 연구에서 제안하는 방법론을 적용한 결과, 단일 프로파일을 사용하는 협업필터링 알고리즘보다 추천 성능이 상당히 개선되었으며 앙상블 방법 중에서는 개별 프로파일 유사도 가중 평균 기법이 가장 높은 추천 성능을 보여주었다. 본 연구는 빅데이터 환경에서 추천시스템을 개발하고자 할 때, 어떠한 성격의 데이터로부터 고객의 특성을 규명하는 프로파일을 만들고 이를 어떻게 결합하여 사용하는 것이 효과적인 지 처음으로 제안하였다는 점에서 그 의의가 있다.

The antenatal self-care, one of antenatal management, was almost done by a pregnant woman herself. But It's especially difficult for primigravidas to cope with the change of being pregnant, and they also had insufficient knowledge of pregnancy, The purpose of this study was to serve as a basis for antenatal management, by grasping how much primigravidas performed antenatal self-care, how much they had maternity-related knowledge, and what factors affected those two factors. The subjects of this study were the primigravidas, selected from among visitors to a general hospital and a hospital for obstetrics and gynecology located in the city of K. A questionnaire survey was carried out over them from July 16 to August 19, 1998, to collect data. The test instrument used in this study for antenatal self-care behavior was one that modified the measurement instrument employed in studies by Kim Hae Won(1996), Lee Mi La(1984), and Yoon Young Mi(1994). Another one for maternity-related knowledge was Kim, Hae Won(1996)'s instrument. The collected data were statistically analyzed by SAS PC+. Frequency and percentage were calculated to find out the primigravidas' general characteristics, and the mean and standard deviation, rank were estimated to determine the degrees of antenatal self-care behavior and maternity-related knowledge, t-test and ANOVA were carried out to identify the general characteristic that affected antenatal self-care and maternity-related knowledge. and the relationship of antenatal self-care behavior to maternity-related knowledge was tested by Pearson correlation coefficient. The findings of this study were as follows; First, the age of the subjects ranged from 18 to 37, and their mean age was 26.43. Their mean gestational period was 24.87 weeks. 45% of the subjects were in the third-term pregnancy. Second, their total mean score in antenatal self-care behavior ranged from 94, the highest, to 36, the lowest. Its average score was 63.81(SD 9.98). The total mean score in maternity-related knowledge ranged from 20, the highest, to 1, the lowest, and its average score was 10.91(SD 4.59, 54.55 percent). Third, the general characteristics that gave impact on the primigravidas' antenatal self-care behavior were age, educational background, gestational period, experience of natural miscarriage, and experience of infertility test. A higher score in antenatal self-care behavior was gained by the primigravida group who had better educational background(F=3.29, p=.02), who was in the late stage of pregnancy(F=4.31, p=.01), who experienced a natural miscarriage(t=2.06, p=.04), and who went through a infertility test(t=-2.19, p=.04). Fourth, the general characteristics that had an influence on maternity-related knowledge were identified as the religion, the term of marriage, and the gestational period. A higher score in maternity-related knowledge was got by the primigravida group who had a religion(t=-2.02, p=.04), and who was in the late stage of pregnancy(F=5.77, p=.003). The term of marriage also made a significant difference(F=3.46, p=.02). Fifth, the relationship of the total mean score between antenatal self-care behavior and maternity-related knowledge was found to be at r=.37(p=.0001). In this study, an attempt was made to affirm the subjects' characteristics, the degree of their antenatal self-care behavior, and the extent of their maternity-related knowledge, to confirm what characteristics affected significantly primigravida's antenatal self-care behavior and maternity-related knowledge, and to verify that there was a relationship between the two variables. The meaning of this study might be backed up by the fact that its findings would serve as a basis for primigravida's efficient antenatal management in the future.

The purpose of this study was to identify the care needs of family-caregivers to the patients with stroke. Subjects were 115 family-caregivers caring for the patients while they were in-patients or out-patients with stroke in two general hospitals and one oriental medicine hospital located in Seoul and Kwang-Ju. The instrument used for this study was made by the researcher on the basis of results of literature review and interviews with family-caregivers, composed of 35 items. Internal validity by calculation of cronbach's alpha with data of respondents was 0.91, which was regarded as high. The Data were analyzed by SAS program, with percentage, mean, t-test, and ANOVA. Factor structures of care needs of family-caregivers were elicited by factor analysis(PCA, Varimax rotation). Datum collection had been from July 1 to August 14, 1997. The results of this study were as follows : 1. The mean score of the sum of the care needs of family-caregivers was 3.96 and the highest-mean item was 'need for immediate care(M=4.77)', and the lowest-mean item was 'need for chaplian's visit (M=2.82)'. 2. Care needs of the family-caregivers were : Need to be informed of the disease, treatment and care ; need of education and assistance related to physical functional level ; need of social support and consultation ; need of management of nursing problem related to immobility ; need of appreciation ; need of the way to communicate with patients ; need of immediate care and help. The highest mean factor was the 'need for immediate care and help(M=4.74)', and the lowest mean factor was the 'need of appreciation(M=3.58)'. 3. The variables influencing the degree of care needs perceived by family-caregivers to the patients with stroke were as follows : There were significant differences between need to be informed of the disease, treatment and care and general characteristic factors, which were family caregiver's sex (p=.0178), caring period(p=.0223) and patient's suffering period(p=.0244). There were significant differences between need of education and assistance related to physical functional level and general characteristic factors, which were patient's paralysis(p=.0177), patient's ADL dependency(p=.0032). There were significant differences between need of social support and consultation and general characteristic factors, which were family caregiver's sex(p=.0055), occupation(p=.0159), religion(p=.0093) and patient's sex(p=.0134). There was significant difference in the degree of need of management of nursing problem related to immobility, according to the patient's ADL dependency(p=.0493). There were significant differences between need of appreciation and general characteristic factors, which were family caregiver's age(p=.0107), sex(p=.0133), and patient's age(p=.0338). There were significant differences between need of the way to communicate with patient and general characteristic factors, which were patient's paralysis(p=.0002) and aphasia(p=.0001). There were significant differences between need of immediate care and help and general characteristic factors, which were family caregiver's caring period(p=.0162) and patient's suffering period(p=.0116). 4. The mean score of patient's ADL dependency was 3. 38 and the highest-mean item was 'ascending and descending stairs(M=4.12)', and the lowest-mean item was 'drinking(M=2.60)'. There was no significant difference in the degrees of care needs related to the patient's ADL dependency. 5. The highest information source of family-caregivers was from the doctors about the disease, treatment and care(26.1%). The second highest one was from mass media(20.8%), and the third one was from the nurses. The above findings may be used as the basic data to seek more efficient way of elevating nursing practice and quality for family-caregivers to the patients with stroke.

The purpose of this study was to identify the degree of sexual adjustment and quality of life in married men with spinal cord injuries and to furnish primary data to sexuality rehabilitation nursing practice which can lead to ideal sexual life and quality of life those men with SCI. Seventy married men with SCI were conveniently sampled in Kwangju, Suncheon, Mokpo and Seoul for responding the questionnaire, which was based on this research. With the research scale, SIS (Sexual interest and satisfaction) by Siosteen et al.(1990) and SB(Sexual behaviour) by Kreuter et al.(1996) were used for the measurement of sexual adjustment. And, for measuring quality of life was used SCI QL-23(Spinal cord injury of life-23) scale by Lundqvist et al.(1997). Data were collected from January 20 to March 20, 1999, using a structured questionnaire. A hundred volumes of questionnaire were used. and 85 volumes were collected, 70 volumes were used as research data after excluding 15 volumes unsuitable to data analysis. The obtain data were analysed using percentage, t-test, ANOVA, Duncan test, and Pearson's correlation by SAS PC+ program. The results were as follows: 1. The mean score of sexual interest and satisfaction of the subjects was 8.42. out of 18. The ways of their sexual behavior after spinal cord injuries were embracing and caressing (62.9%), kissing(58.6%), caressing breast with hands (55.7%), caressing breast with hands (52.9%), caressing genitals with hands (37.2%), caressing genitals with mouth(30.0%) and sexual intercourse (18.6%). The mean score of quality of life was 52.53 out of 100. 2. Age(F=3.24, p=.045) and caregiver (F=4.02, p=.022)were major variables which reveals significant differences in terms for sexual interest and satisfaction. The later results on Duncan's test showed that subjects who were in their 30s or 40s were significant higher than subjects whose age were in their 50s in their sexual interest and satisfaction. Also subjects with their spouse's care or mother's care were higher than those with other's care. 3. Subjects with incomplete paraplegia were higher than those with the complete paraplegia in sexual interest and satisfaction (F=3.01, p=.036). 4. Variables that showed the significant differences in the quality of life were education(t=2.860, p=.007) and period of marriage(t=2.125, p=.037). and occupational status(t=-2.161, p=.034). High school graduates, those who married before spinal cord injuries and those who didn't have occupation were higher than the other subjects. 5. Variables that revealed significant differences in the quality of life were time passage after spinal cord injuries(F=8.72, p=.001) and injured level of spinal cord(F=3.32, p=.042). Duncan's test showed that subjects who had lived for less than 4 years were higher those with time passage of 5-9 years and 10 years. Also subjects with lumbar injuries were higher than those with thoracic injuries in terms of quality of life. 6. There was negatively correlated between sexual interest and satisfaction and quality of life(r=-.256, p<.05). As a result of these findings sexuality rehabilitation for individuals with SCI was very important issue for their quality of life. Thus, registered nurses who care clients with SCI should activily participate in the client's sexual needs. Also, various sexual behaviors as well as sexual intercourse should be encouraged for the sexual adjustment of client's with SCI.

최근 급격히 증가하는 조경공사의 추세에 비추어 볼 때 특성수목과 규격을 편중되게 사용하며, 시간 경과에 따른 수목의 크기 변화로 인해 외부공간의 공간배분이 달라짐을 고려하지 않고 단기적의 효과만을 목적으로 지나치게 밀식하는 경향이 있어 시공후 5년, 10년, 20년 후에는 선택적으로 수목을 제거하여야 하는 추가적인 관리부담을 끼치므로 배식 설계의 문제점으로 지적되고 있다. 본 연구는 주요조경수목의 수형예측모델을 개발하기 위한 1단계의 연구로써 시간경과에 따른 수목의 크기변화를 미리 에측하여 식재간격을 결정하거나 식재군의 수관연락선(Skyline)의 형태를 인식하는데 기초자료로 활용되도록 하는 것에 연구목적을 두었다. 본 연구의 수행결과 다음과 같이 결론을 얻을 수 있었다. 1) 느티나무와 스트로브잣나무, 백목련에 대해 수령과 근원 혹은 충고직경, 수고, 관수폭, 기하고와 근원 혹은 흉고직경과의 관계를 파악하고자 회귀분석한 결과 높은 회귀계수를 보임으로써 높은 정도의 관련이 있음을 나타내었다. 2) 시간경과에 따른 수종별 크기의 변화는 수고의 경우 스트로브잣나무, 느티나무, 백목련의 순서로 생육 속도가 빨랐고, 수관폭의 경우에는 식재후 10년이 되기까지는 수종간 큰 차이가 없으며, 20년후에는 느티나무의 등가율이 제일 크게 나타났다. 기하고에 있어서는 느티나무의 경우 수령이 증가함에 따라 가지가 아래로 처짐으로 인하여 감소하는 경향을 나타내었다. 3) 조경수목의 식재간격은 성목시 수관폭의 70∼100%로 하는 것이 일반적인 이론인데, 각 수종별로 많이 사용하는 규격을 식재한 후 10년, 20년 후에 30%가 겹치는 식재간격일 때 10년후에 30%가 겹치게 되며, 4.8m 일 때 20년후에 30%가 겹치는 것으로 나타났다. 또한 스트로브잣나무는 3.2m일 때 10년후에는 30%가, 4.2m일 때 20년 후에 30%가 겹치게 되며, 백목련의 경우는 3.3m일 때 10년 후에 30%가 겹치며, 4.2m 일 때 30%가 겹치는 것으로 나타났다. 따라서, 10년 후까지는 수종간에 차이가 없으나 20년 후를 고려하면 느티나무의 식재간격은 다소 넓어져야 한다고 생각된다.

Human and monogastric animals can not synthesize 10 out of the 20 amino asids and therefor need to obtain these from their diet. The plant seed is a major source of dietary protein. It is particular important in their study to increase nutritional quality of the seed storage proteins. The low contents of lysine, asparagine and threonenein various cereal seeds and of cystein and methionine. In legume seeds is due to the low proportions of these amino acids in the major storage proteins, we have tried to apply the three strategies; (1) mutagenesis and selection of specific amino acid analogue resistance, (2) cloning and expression study of lysine biosynthesis related gene, (3) transfomation of lysine rich soybean glycinin gene. The 5-methyltryptophan (5MT) resistant cell lines, SAR1, SAR2 and SAR3 were selected from anther derived callus of rice (Oryza sativa L. "Sasanishiki"). Among these selected cell lines, two (SAR1 and SAR3) were able to grow stably at 200 mg/L of 5MT. Analysis of the freed amino acids in callus shows that 5MT resistant cells (SAR3) accumulated free tryptophan at least up to 50 times higher than those that of the higher than of SAS. These results indicated that the 5MT resistant cell lines are useful in studies of amino acid biosynthesis. Tr75, a rice (Oryza sativa L., var. Sasanishiki) mutant resistant to 5MT was segregated from the progenies of its initial mutant line, TR1. The 5MT resistant of TR75 was inherited in the M8 generations as a single dominant nuclear gene. The content of free amino acids in the TR75 homozygous seeds increased approximately 1.5 to 2.0 fold compared to wild-type seeds. Especially, the contents of tryptophan, phenylalanine and aspartic acid were 5.0, 5.3 and 2.7 times higher than those of wild-type seeds, respectively. The content of lysine is significantly low in rice. The lysine is synthesized by a complex pathway that is predominantly regulated by feedback inhibition of several enzymes including asparginase, aspatate kinase, dihydrodipicolinat synthase, etc. For understanding the regulation mechanism of lysine synthesis in rice, we try to clone the lysine biosynthetic metabolism related gene, DHPS and asparaginase, from rice. We have isolated a rice DHPS genomic clone which contains an ORF of 1044 nucleotides (347 amino acids, Mr. 38, 381 daltons), an intron of 587 nucleotides and 5'and 3'-flanking regions by screening of rice genomic DNA library. Deduced amino acid sequence of mature peptide domain of GDHPS clone is highly conserved in monocot and dicot plants whereas that of transit peptide domain is extremely different depending on plant specie. Southern blot analysis indicated that GDHPS is located two copy gene in rice genome. The transcripts of a rice GDHPS were expressed in leaves and roots but not detected in callus tissues. The transcription level of GDHPS is much higher in leaves indicating enormous chloroplast development than roots. Genomic DNA clones for asparaginase genes were screened from the rice genomic library by using plaque hybridization technique. Twelve different genomic clones were isolated from first and second screening, and 8 of 12 clones were analyzed by restriction patterns and identified by Southern Blotting, Restriction enzyme digestion patterns and Southern blot analysis of 8 clones show the different pattern for asparaginase gene. Genomic Southern blot analysis from rice were done. It is estimated that rice has at least 2-3 copy of asparaginase gene. One of 8 positive clones was subcloned into the pBluescript SK(+) vector, and was constructed the physical map. For transformation of lysine rich storage protein into tobacco, soybean glycinin genes are transformed into tobacco. To examine whether glycinin could be stably accumulated in endosperm tissue, the glycinin cDNA was transcriptionally fused to an endosperm-specific promotor of the rice storage protein glutelin gene and then introduced into tobacco genomic via Agrobacterium-mediated transformation. Consequently the glycinin gene was expressed in a seed-and developmentally-specific manner in transgenic tobacco seeds. Glycinin were targeted to vacuole-derived protein bodies in the endosperm tissue and highly accumulated in the matrix region of many transgenic plant (1-4% of total seed proteins). Synthesized glycinin was processed into mature form, and assembled into a hexamer in a similar manner as the glycinin in soybean seed. Modified glycinin, in which 4 contiguous methionine residues were inserted at the variable regions corresponding to the C - teminal regions of the acidic and basic polypeptides, were also found to be accumulated similarly as in the normal glycinin. There was no apparent difference in the expression level, processing and targeting to protein bodies, or accumulation level between normal and modified glycinin. glycinin.

Nursing standards determine the type and extent of services that are delivered to the patients and define quality care and communicate the institution's expectations of care. Thus, taking the standard of care and incorporating it into a welldefined indicator of excellent patient care becomes one of the first activities in setting up the nursing service's quality assurance process. The purpose of this study was to determine the impact of using a nursing care standards for the quality of nursing care in gastrectomy patients. The subjects were composed of fourty-two under going gastrectomy patients with stomach cancer in general surgery nursing care unit of K University Hospital in Pusan. The data was collected from January 3 to April 13,1996. The subjects were divided into a control group - those admitted from Jan.3 to Feb.12 and an experimental group those admitted from Feb.18 to April 13. The instruments used for this study were a nursing care standards in gastrectomy patients developed by the investigator and an evaluation tool for the quality of nursing care in abdominal surgery patients developed by Byoung-Sook Lee in 1995. The data was analized by means of chi-square test, t-test and Cronbach-alpha test with the SAS System. The result was as follows : The hypothesis, that scores of the quality of nursing care in the experimental group would be higher than that of the control group. was supported(t=-6.12, p=0.00). The detailed results of each standards of evaluation tool were as follows : The mean score of the experimental group was significantly higher than that of the control group in audit standard 1:'Collection of basic data of the patients', (t=-3.76, p=0.00). The mean score of the experimental group was significantly higher than that of the control group in audit standard 2 : 'Defining nursing diagnoses(or nursing problems)', (t= (-), p= (-) ). The mean score of the experimental group was significantly higher than that of the control group in audit standard 3:'Estabilishment of nursing care plan according to nursing diagnoses(or nursing problems)',(t= (-), p= (-) ). The mean score of the experimental group was significantly higher than that of the control group in audit stndard 4:'Implimentation of nursing care plan', (t=-2.38, p=0.01). The mean score of the experimental group was significantly higher than that of the control group in audit standard 8 : 'Increase of the knowledge of health related to surgery',(t=-2.40, p=0.01). No significant differences between the mean scores of the experimental group and that of the control group in audit standard 5 : 'Recover and maintain of the physical function', audit standard 6:'Prevention of the post-operative complication', audit standard 7 : 'Decrease of discomfort caused by operation', and audit standard 9 : 'Patient satisfaction in nursing care' were found. The standards of evaluation tool were devided into two dimension. One was process dimension which contains four standards(audit standard 1 to 4), the other was outcome dimension which contains five standards(audit standard 5 to 9). The mean score of the experimental group was significantly higher than that of the control group in process dimension (t=-12.30, p=0.00), but no significant difference between the mean scores of the experimental group and that of the control group in outcome dimension was found. From these results, it is concluded that using a nursing care standards in gastrectomy patients promotes quality of nursing care and nursing care standards of various fields are necessary for effective nursing care.
