본 연구는 한국의 장기요양서비스 제도적 맥락 속에서 발생한 시장화와 공존하고 있는 공공성의 관점에서 요양보호사의 근로조건이 서비스 질에 미치는 효과를 실증분석 하였다. 기존 연구들은 사회서비스의 낮은 생산성과 시장화로 가중된 저임금노동시장의 문제가 서비스 질 저하를 가져온다고 추론한 것이지, 근로조건과 서비스 질의 두 변수간의 인과관계를 규명한 것이 아니다. 본 연구의 노인장기요양서비스 제도적 맥락에서 본 요양보호사의 근로조건과 서비스 질과의 이론적 관련성은 Daly와 Lewis(2000)의 돌봄의 통합적 접근을 통해 조망하였다. 자료는 전국에 있는 노인장기요양시설을 소유권을 중심으로 비비례층화표집하여 248개 조직에 대한 설문조사를 통해 수집하였고, 이를 다시 인터넷 자료와 병합하였다. 분석결과, 요양보호사의 근로조건 가운데 3개 영역에서 임금수준이 높을수록, 부가급여가 존재할수록, 교육 및 훈련을 지원할수록 서비스 질이 높은 것으로 나타났다. 이는 정부가 규제하는 노동시장정책과 평가제도상의 최소기준을 넘어서는 조직의 규범적 차원에서의 근로조건과 보상체계가 장기요양서비스 질에 긍정적인 영향을 미치고 있다는 것을 보여준다.

The objective of this study was to examine the effects of relationships between food service companies and their client companies by surveying employees working at cafeterias among a food service companies' client companies. For this purpose, previous research was reviewed, and confirmatory research was conducted using a questionnaire. In the questionnaire survey, the subjects were sampled through convenience sampling from the client companies of A Food Service Company, and 182 valid questionnaires were used in the analysis. The results of this study are summarized as follows. First, the characteristics of the relationship between the food service company and its client companies, which were reputation, communication, operation skill, and contact-point employees' service quality, had a significant effect on trust, and the effect was high in the order of contact-point employees' service quality, communication, operation skill, and reputation. Satisfaction was significantly affected by reputation, operation skill, and contact-point employee' service quality, but not by communication. The effect was high in the order of contact-point employees' service quality, reputation, and operation skill. In addition, reputation, communication, operation skill, and contact-point employees' service quality had a significant effect on long-term orientation, and the effects were high in the order of reputation, contact-point employees' service quality, communication, and operation skill. Second, with regard to the quality of relationships between a food service company and its client companies, trust had a significant effect on satisfaction. Third, among the factors related to the quality of relationships between the food service company and its client companies, trust and satisfaction had a significant effect on long-term orientation, and the effect of satisfaction was higher than that of trust. This study has scientific significance as one of only a few studies on factors affecting the long-term relationship between food service companies and their client companies, along with managerial implications that contact-point employees' capabilities are most important in service businesses, and thus efforts should be made at employing and educating them properly.

To analyze the correlation between biological phenotypes of HIV-1 isolates and disease progression, we selected 9 long-term non-progressors (LTNP) and 12 rapid progressors (RP) from HIV-1 infected Korean. We isolated HIV-1 isolates by culture of PBMC of LTNP and RP with normal PBMC and measured HIV-1 p24 antigen production. The HIV-1 isolation rate from LTNP was 55.6% (5/9). And 4 HIV-1 LTNP isolates were non-syncytium inducing (NSI) phenotype and showed slow/low replication. The HIV-1 isolation rate from RP was 91.7% (11/12) which was higher than that from LTNP. Besides 3 RP HIV-1 isolates which showed syncytium inducing (SI) phenotype, 8 RP HIV-1 isolates showed NSI phenotype in normal PBMC and MT-2 cell line. All RP HIV-1 isolates replicated more rapidly than LTNP HIV-1 isolates. Comparing the replication kinetics and syncytium forming capacity of HIV-1 isolates from LTNP and RP, we suggest that the difference of biological phenotype of HIV-1 isolates could be related with disease progression of HIV-1 infected persons.

Objectives: This research has executed a new oral health promotion program among the elderly residents of a long-term care center, which purpose was to verify its effectiveness of oral health promotion through the improvement of their oral function. Methods: This study has selected the elderly over the age of 65, capable of communication, who use a long-term care center over the period of two months between July and September 2014. The subjects who remained until the final analysis numbered 50 excluding the dropouts during the program session (experimental: 33, control : 17). The oral stretching program was exercised two days a week, for total of two months. Each function was assessed by the standardized methods and measurement equipment. Also the sum of each function was converted into the oral health grade. Results: The oral function score of the experimental group also showed a statistically significant difference after the execution of the program, where the oral function score of experimental group increased $6.70{\pm}1.30$ from $4.95{\pm}0.89$ after the execution of the program (p<0.05), while the comparison group showed no valid statistical difference with the score result of $5.00{\pm}0.87$ down from $5.11{\pm}0.93$ after the execution of the program (p>0.05). Conclusions: Therefore if the oral health promotion program is reflected to the welfare policy in the future, it can be said that it contributes to the improved health status of the elderly who reside in the long-term care centers.

Purpose: The purpose of this manuscript is to discuss the need for use of evidence based practice (EBP) in LTC, the current use of evidence in long term care facilities and what we know about adoption of the use of EBP in LTC. Methods: Literature review and reporting of findings from the M-TRAIN study that was a quasi-experimental design to test the effectiveness of an intervention to increase the use of EBPs for urinary incontinence and pain in 48 LTC facilities. Results: Barriers to adopting EBPs include lack of available time, lack of access to current research literature, limited critical appraisal skills, excessive literature to review, non-receptive organizational culture, limited resources, and limited decision-making authority of staff to implement change. Strategies to promote adoption of EBP include the commitment of management; the culture of the home; leadership; staff knowledge, time, and reward; and facility size, complexity, the extent that members are involved outside the facility, NH chain membership, and high level of private pay residents. Findings from the M-TRAIN add, stability of nurse leader and congruency between the leaders perception of their leadership and the staff's perception of the leadership. Conclusion: There is clear evidence of the need and the benefits to residents of LTC and to the health care system yet adoption of EBP continues to be slow and sporadic. There is also evidence for the process of establishing best evidence and many resources to find the available EBPs. The urgent need now is finding ways to best get the EBPs implemented in LTC. There is growing evidence about best methods to do this but continued research is needed. Clearly, residents in LTC deserve the best care possible and EBPs represent an important vehicle by which to do this.

To characterize the molecular nature of human immunodeficiency virus (HIV)-1, we determined the full-length HIV-1 sequences from cultured peripheral blood mononuclear cells (PBMC) of a Korean long-term nonprogressor (LTNP). Without antiretroviral therapy, the individual has maintained CD4+ T counts over $500/{\mu}l$ from 1989 to 1999. Plasma viral RNA copy was 992 U/ml in 1998. Culture supernatant showed positive from culture days 9. A series of 9 overlapping PCR products were amplified from cultured PBMC and cloned About 9.2 kb from R of 5' LTR to R of 3' LTR was determined by automated sequencing. The G-to-A hypermutations were shown throughout the entire region. As a result of G to A hypermutations, premature stop codon was found in integrase coding region. Though there was no recombination between subtypes over all genomes, TATA box in both LTRs was TAAAA which is detected in subtype E instead of TATAA in subtype B. And, there were nucleotide GC insertion between $NF-{\kappa}B$ I and Sp1 III, and duplication of $TCF-1{\alpha}$ in LTR. We could not find any deletion of amino acid in Nef, Gag, Pol and Env gene. This study is the first report on molecular nature of full genomes of HIV-1 isolated in Korea.

This study was carried out to determine the optimal storage conditions by examining the effects of the storage conditions on the quality of red pepper powder during storage in households. Red pepper powder was stored at room temperature ($20^{\circ}C$), refrigeration (2 and $-1^{\circ}C$) and frozen (-5 and $-20^{\circ}C$) for 3, 6, 9 and 12 months. The ASTA color value, capsanthin content and redness ($a^{\ast}$) of the red pepper powders stored at -5 and $-20^{\circ}C$ were not decreased significantly depending on the storage temperatures until 9 months. The pH of red pepper powder stored at $20^{\circ}C$ decreased significantly until 9 months and increased at 12 months. The microbiological quality of the red pepper powder stored at -5 and $-20^{\circ}C$ was more stable during long-term storage. In the sensory evaluation of red pepper powder stored under all conditions, the overall freshness, redness, hot flavor, moisture release, and edibility decreased with increasing storage period from the control to 12 months. Moisture release increased from 3 months to 12 months. Overall, red pepper should be stored at low temperatures (2, $-1^{\circ}C$) for up to 6 months, and frozen (${\geq} -5^{\circ}C$) for 6 to 9 months. The optimal temperature for long-term storage (${\geq}9$ months) was $-20^{\circ}C$.

This study investigated the effect of temperature deviation on the water-holding capacity, tenderness, lipid oxidation, and color stability of Korean Hanwoo (韓牛) beef during long-term aging. The striploins (M. longissimus lumborum) were aged for 56 days at 2±1℃ (T1), 2±2℃ (T2), or 2±3℃ (T3). Drip loss and cooking loss were higher (p<0.05) in T3 than in T1 on day 56. The Warner-Bratzler shear force value was similar for all treatments during aging times. On day 56, the content of 2-thiobarbituric acid reactive substances was higher (p<0.05) in T3 as compared to T1. The CIE L^* and b^* values were similar for all treatments, but the a^* value was lower (p<0.05) in T3 than in T1 on the last day. These findings indicate that high temperature deviation adversely affects the water-holding capacity, lipid oxidation stability, and color stability of Hanwoo beef during long-term aging.

Mainly due to the slanted focus on the mechanism and regulation of neuronal aging, research on astrocyte aging and its modulation during brain aging is scarce. In this study, we established aged astrocyte culture model by long-term culturing. Cellular senescence was confirmed through SA-β-gal staining as well as through the examination of morphological, molecular, and functional markers. RNA sequencing and functional analysis of astrocytes were performed to further investigate the detailed characteristics of the aged astrocyte model. Along with aged phenotypes, decreased astrocytic proliferation, migration, mitochondrial energetic function and support for neuronal survival and differentiation has been observed in aged astrocytes. In addition, increased expression of cytokines and chemokine-related factors including plasminogen activator inhibitor -1 (PAI-1) was observed in aged astrocytes. Using the RNA sequencing results, we searched potential drugs that can normalize the dysregulated gene expression pattern observed in long-term cultured aged astrocytes. Among several candidates, minoxidil, a pyrimidine-derived anti-hypertensive and anti-pattern hair loss drug, normalized the increased number of SA-β-gal positive cells and nuclear size in aged astrocytes. In addition, minoxidil restored up-regulated activity of PAI-1 and increased mitochondrial superoxide production in aged astrocytes. We concluded that long term culture of astrocytes can be used as a reliable model for the study of astrocyte senescence and minoxidil can be a plausible candidate for the regulation of brain aging.
