The purpose of this study is to examine the effects a music group therapy program has on cognitive function and life satisfaction. We targeted the elderly who are receiving service at a daycare center. This study monitored seventeen elderly subjects who were available for language communication, walking, and defecation function even if the subject had a slight mind-body function disorder based on using the service of the daycare facilities. The subjects visited each of the welfare centers one week prior to the Korean classical music group therapy program. We conducted a pre-test of MMSE-K(Mini-Mental State Examination, Korean version) modified by Park and Gwon(1989). We also supplemented the MMSE developed by Folstein(1975) and LSI-A(Life Satisfaction Index) for the elderly developed by Neugarten, Havighurst and Tobin(1961). We conducted the Korean classical music group therapy program for 15 sessions at 50 minutes each for 1~2 times a week from July 9 to September 13, 2013 at the daycare center for OO senior welfare center. The welfare center belongs to the experimental group, excluding the OO general welfare center, which is the control group. Finally, we carried out the post-test of the MMSE-K and LSI-A in the same manner as the pre-test. We carried out the post-test on July 17, 2013, 4 days after concluding the Korean classical music group therapy program. A t-test was used in order to analyze the differences in cognitive function and life satisfaction according to each group. We used SPSS/WIN 18.0 program. This study has significance by proving that the use of Korean classical music is conducive in the improvement of cognitive function and life satisfaction of the elderly at the daycare facilities. Also, we presented the actual contents of the study to the clinical field.

The ptsH and ptsI genes of Lactococus lactis subsp. lactis ATCC 7962 (L. lactis 7962), encoding the general proteins of phosphotransferase system (PTS) components, HPr and enzyme I, respectively, were cloned and characterized. A 1.3 kb PCR product was obtained using a primer set that was hybridized to the internal region of the L. lactis 7962 pts HI genes and then subcloned into a low-copy number vector, pACYC184. The 5' upstream and 3' downstream region from the 1.3 kb fragment were subsequently clone using the chromosome walking method. The complete ptsHI operon was constructed and the nucleotide sequences determined. Two ORFs corresponding to HPr (88 amino acids) and enzyme I (575 amino acids) were located. The ptsHI genes of L. lactis 7962 showed a very high homology (84-90%) with those genes from other Gram-positive bacteria. A primer extension analysis showed that the transcription started at either one of two adjacent bases upstream of the start codon. Using a Northern analysis, two transcripts were detected; the first, a 0.3 kb transcript corresponding to ptsH and the second, a 2 kb transcript corresponding to ptsH and ptsI. The transcription level of ptsH was higher than that of ptsI. The concentration of the ptsH transcript in cells grown on glucose was similar to that in cells grown on lactose, yet higher than that in cells grown on galactose. The ptsI transcript was scarcely detected in cell grown on lactose or galactose. The ptsI transcript was scarcely detected in cells grown on lactose or galactose. The results of a sequence analysis and Northern blot confirmed that the ptsH and ptsI genes of L. lactis 7962 were arranged in an operon like other known ptsHI genes and the expression of the ptsHI genes was regulated at the transcriptional level in response to the carbon source.

This study was performed to investigate the general prepartum behavioral ethogram of Bos taurus coreanae (Hanwoo cow). In this study, 4 pregnant cows were placed in a separate area. We recorded the behaviors of the cows using time lapse VCR for 48 hours and analyzed behaviors with the scan point sampling method. We observed maintenance behaviors, social behaviors and ingestion behaviors. During the observation period, the time budgets of behaviors in order of frequency were LD(lying down, 38.2%), ST(standing, 24.7%), EA(eating, 10.7%), WA(walking, 7.2%), LR(lying down rumination, 5.6%), SR(standing rumination, 3.3%), TW(tail wagging, 3.1%) and SG(self grooming, 1.8%). The time budgets of the other behaviors such as PG(pairwise grooming), FC(fly catching) were negligible (<1%).

The purpose of this study is to provide information searching for health promotion, nutrition improvement, and health care of the impaired elderly by ADL(Activity of Daily Living) and IADL(Instrumental Activity of Daily Living). The subjects were divided into the Assistant Needed Group and No Assistant Needed Group for living in line with the responses of ADL(10 items like dressing, washing, move etc.) and IADL(10 items like housekeeping, using transportation, shopping, Phone call etc.). Survey was made for health behavior, health risk habit, dietary management status and diet intake by 24 hr-recall and questionnaire method. 242 subjects were collected in 12 cities or Gun districts in Gyeonggi Province, S. Korea. Survey was carried out by regional home extension workers using interview method. Statistical analyses were made using SAS (Version 8.1). Chi-Square Tests and General Linear Models. The subjects of impaired ADL elderly was 26.5% and it composed 30% of the total male and 22.2% of the total female. The demographic status of the impaired ADL elderly showed no difference from that of the normal elders, elementary school educated (73.4%), with spouse (43.8%) or with adult children(37.5%), using monthly living cost of 500-1,000 thousand won(35.9%). Mean age was 74.05 years compared to 72.25 years of normal elders. However, there was no significant difference from the normal and impaired ADL group, regular exercise(60.0%), with walking (90.0%), no-smoke(54.7%) and no-drink(48.4%). Kind of disease was not different from the one in impaired and normal group, with cardiovascular disease(32.3%), with diabetes mellitus(8.1%), joint lumbago neuralgia(32.3%) and osteoporosis(9.7%). Gastrointestinal complaints of the impaired ADL group were nausea(57.8%), chronic indigestion (23.4%), constipation (14,0%) and vomiting(3.7%). Sleeping time required for the impaired was longer than that for the normal group by 10hours(4.7%) or 8-10hours(20.3%), which consisted 1.7% and 16.6% respectively. Nutrient intake of the impaired ADL group was low compared to normal range elders: Energy(1260kca1), Protein(52.75g). There was gender difference in nutrient intake; the male impaired group showed no significant difference from the normal group but it was significantly lower in female impaired group. These results suggest that low quality of life and low economic status of the impaired ADL elderly require congregate meal in village hall to cover the lack of side dishe variety. And nutrition education program including community assistance would be required for the impaired ADL elderly together with the sufficient food and exercise practice. By operating nutrition education program, the impaired ADL elderly would maintain more enhanced quality of life and ameliorate the ADL capability.

This study examines a way to install a crosswalk that can improve pedestrians' convenience and safety and that goes beyond the crosswalk design standard of existing roundabouts. When a scrambled crosswalk, one of the crosswalk installation methods, is introduced to the roundabout system, it shortens the cross-walking distance of pedestrians and thus enhances convenience. Although the installation of a scrambled crosswalk may enhance pedestrians' convenience, it may obstruct vehicular traffic. Thus, this study presents standards for reasonable diagonal crosswalk installation based on the investigation on its effects on a vehicle's delay time. This study includes an analysis of the various geometric structures of roundabouts. The study results show that as v/c and the number of pedestrians increased, the delay time after the installation of a scrambled crosswalk increased although the extent was different. In general, the effect of the installation of a scrambled crosswalk was insignificant regardless of the number of pedestrians when v/c was under 0.6. When the number of pedestrians was 300/hour or lower, the difference in the delay time was quite insignificant regardless of v/c. In addition, as the inscribed circle of the roundabout was larger, the difference in the delay time decreased depending on v/c and the number of pedestrians.

The research was started out of curiosity for what made 's fast and trilling pace possible although it is an old movie. The center of what made it possible was its use of the Long Take - Long Take was used in all of the scenes and in some cases only long take was used. What is interesting is the film maker's use of various cinematic techniques to prevent the scene from being too slow and keep the audience immersed in the characters. In one shot, acting in addition to Mise-en-Sc$\grave{e}$ne were used to provide psychological immersion of character and scene. The use of Long Take, with the exception of some intentional scenes, was difficult to notice without conscience observation. All the components that make up Long Take. camera walking and lighting as well as actor's dialog and performance and scene movement all beautifully came together. The Long Take is generally replaced by many different sort shots. However, Mike Nichols clearly demonstrates the benefit of Long Take. In the movie, the general aesthetics from the use of Long Take is slightly altered for a different purpose. The specific methods and effects used in the application of Long Take is the subject of this study.

In 2007, Long-Term Care Insurance Law was enacted to share the family burden of caring for the elderly who are unable to perform every day living activities due to their old age and chronic diseases such as senile dementia, diabetes mellitus, stroke and more. Backed by this law, since 2008, care workers have been sent to the elderly care centers or each elder's home to help them not only with their recovery from illnesses, but also with general activities from dressing, eating, bathing, walking even to toileting. However, according to the recently released survey by National Human Rights Commission, it has been found that the caring workers are in a very poor working condition including low income, abused blanket wage system, shortage of welfare services, extra works and even sexual harrassment. It is becoming an important issue due to fast-ageing population, the fact that the care workers have had experiences of violation in their right of labor while they are at work needs to be carefully treated. In that sense, this article presents some difficulties the caring workers face and proposes effective ways to solve these problems through the perspective of human rights and human labor rights based on the report written by National Human Rights Commission. In short, for this law to function properly and to boost the worker's capability of providing better services to beneficiaries, followings can be good answers - enhanced management and supervision on caring plans and care centers, providing immediate counselling and protection for victimized care givers, training courses offered to promote service receiver's sincere respect and strengthened awareness upon care givers.

The purpose of this study was to compare the foot plantar pressure and temperature changes of the developed combat boots with functional impact absorption and ventilation insole. A total of 11 male subjects(age: $21.8{\pm}2.2yrs$, height: $174.3{\pm}3.6cm$, weight: $71.6{\pm}8.6kg$, foot length: $261.0{\pm}1.0mm$) were recruited to compare the foot plantar pressure and temperature changes of the three types of combat boots: Combat boots A (generalized combat boots), Combat boots B (developed combat boots with ventilation function), Combat boots C (Application of ventilation function and impact absorption insole to combat boots B). Pedar-X and a portable thermistor temperature sensor were used to measure the foot plantar pressure parameters and the internal temperature of the combat boots, respectively. One-way ANOVA was used to compare the results of plantar pressure and temperature changes. The results were as follows: First, in the foot plantar pressure parameters, combat boots C showed the significant lower maximum foot plantar pressure in the right/left rear foot compared with combat boots A and average foot plantar pressure in the left foot compared with combat boots B. Second, after 40 minutes from the start of walking, the developed combat boots B and C showed the significant lower temperature than the general combat boots A.

The purpose of this study is to examine whether there is a difference in the awareness of death based on happiness (since attitude or way of life differs among the general public, depending on the perception of death), and to investigate whether there is a difference in the interest in hospices between a group with a high happiness index and a group with a low happiness index. A survey was conducted on 200 men and women aged over 20 who participated in a walking event held in a metropolitan city on April 22, 2017. The survey consisted of eight demographic items: gender, age, education, occupation, marital status, family cohabitation, religion, and health status. It included 29 questions regarding happiness and nine questions regarding the perception of death. For the statistical tests, a chi-square test, an independent sample t-test, correlation analysis, and canonical correlation analysis were performed on the items of the survey based on a happiness index. The results of the study showed that, for a suitable place for death, medical institutions was the highest score (46.3%) for the group with a low happiness index, and own house was highest (59.4%) for the group with a high happiness index. This was a significant difference. It is thought that management systems should be supplemented by professional manpower, educating people so as to increase the utilization rates of home-based hospice as a way for patients to die in a comfortable and familiar place because, for Korea, death is much more common in hospitals. It is also necessary to increase the awareness of death and to make effective use of hospices through individual and various other approaches, considering the demographics of the subjects.

Super high-rise buildings of combined use such as large shopping malls and multiplex etc. have larger parking facilities than general buildings and are characteristic of an increase in the number of the entrance and the exit connecting internal external space of the parking lot. These features cause a congestion of internal traffic by increasing car driving distance in the parking lot, and vehicle idling increases by drivers wander the parking lot in order to find parking space. In addition, they make drivers suffer from lots of difficulties due to parking including increasing their walking line after parking. Therefore, in this study, we developed individual parking information provision algorithm to specify the optimal parking place for drivers according to the purpose of visiting a building and the drivers' moving path, and selected new construction site for the second lotte world in order to evaluate the algorithm developed and performed evaluation. As a result of the evaluation, it was analyzed that in the case of applying the individual parking information provision algorithm compared to the existing parking information provision algorithm, moving distance in the parking lot decreases around 7.43~83.4%, and that in the case of $CO_2$ emission, it decreased about 47.7% on average, which indicates that the efficiency resulted from application of the individual parking information provision algorithm is very high as the application effects are tested.
