This study was designed out to develop a home health care service for nurses working in community care services. This study investigates actual conditions at welfare institutions related to health needs the demands of clients, and the state of home health care services we hope that this study will improve upon the current service system. In Korea home health care services are still developing and only new becoming a part of the health care supply system. The data was collected by recording the client home nursing assessments modified to the situation of UTMB home health agency. In this study 107 clients were selected for home care who needed care for physical and mental deficits. The study lasted from March to November of 1995 at one of the welfare service institutions in Chunchon city. The results show that those who most frequently needed care services were over 50 years old with a health deficit of 80.3%, followed by sex as women who needed care at 59.8%. 50.5% of the clients had very little education. 99.1% of the clients live with their family, and a medical diagnostic analysis reveals that 73.9% of the 5 year period of illnesses were the following : 38.8% - muscular -skeleton system disorder, 24.4% - hypertension and stroke, 25.7% sole disease of arthritis. For behavioral conditions 43.3% of the patients were without care services, 56.6% of the patients were taking treatment that 73.5% of those were taking medication. The most main complaint of patients were 22.4% of pain in the extremities, next were 16.8% of a limitation of body activities, 15.0% was lumbo-sacralgia. According to the investigator who was a senior student nurse, the following suggestions were made: 32.7% for curative medical services, 29.9% for physical exercise, 19.6% for emotional support. Consultation nursing services consisted of 67.2% for physical therapy, 11.2% for the maintaining healing, 9.4% for counseling. The patients at home, required assistance most frequently for muscular-skeleton problems under the category of physical systems (33.3%). But, on the other hand, 49.5% of the patients required care givers at home, 28.2% had a knowledge deficit, 21.0% had malnutrition, 18.4% had bad impaired communication. The character of health problems were devided into chronic disease(67.0%), accidents(I3.1%), and general disease(15.9%). 86% of the disabled client had an impairment of the physical system. Eating (86.9%) , Toileting(77.6%), and personal care showed much the same of ADL condition, the level and range of achievement of mobility, the most frequently self performed was 81.3% only in a room size area, and 40.2% were completely dependent when going out. Although there were a large number of home care services in th community at these welfare institutions, many clients needed a variety of curative services. As policy changes have gathered momentum, responsibility for the development of a more suitable program was demanded by the clients from the community.

The coverage of soft tissue defects around the knee joint or upper one third of lower leg presents a difficult challenge to the reconstructive surgeon. Various reconstructive choices are available depending on the location, size and depth of the defect. The authors present their clinical application of a medial sural artery perforator island flap as a useful alternative method for upper one third of lower leg and knee reconstruction. From 2002 to 2004, we operated total 4 patients (total 4 flaps) using the medial sural artey perforator island flap for coverage of the defect on upper one third of lower leg and knee, of 4 patients, 3 patients was men and one was woman. Average patient age was 54.6 years. The largest flap obtained was 10x8cm2. Postoperative follow up of the patients ranged from two to 33 months. In two cases, defects was located on upper one third of lower leg and in other two cases, defects were on the knee. All four cases had bone exposure open wound. In angiography, 2 cases had injured in the anterior tibial artery, 1 case had injured in the posterior tibial artery. There were no diabetes or other vascular disease. All 4 flaps were survived completely, without minor complications such as venous congestion and hematoma. Donor morbidity was restricted substantially to the donor linear scar. There were no functional impairment. As the main advantages of the medial sural perforator island flap, it ensures constant location and reliable blood supply without sacrificing any main source artery or damaging underlying muscle. This procedure is valuable extension of local flap for defect coverage with minimal functional deficit donor site and good aesthetic result on the defect. We consider it as one of the useful methods of the upper one third of lower leg and knee reconstruction.

The purpose of this study were to investigate the effect of fasting and vitamin B6 repletion on tissue concentration of pyridoxal 5-phosphate and urinary excreteion of 4-pyridoxic acid in vitamin B6 deficient rats. Sixty six rats(6 per group) were fed either a vitamin B6 deficient diet (-B6) or a control diet (+B6) for 6 weeks and then rats were repleted with +B6 diet for 2 weeks. Rats were fasted for 1 and 3 days and for 3 days after repletion. Pyridoxal 5-phosphate (PLP) concentration in plasma, liver, skeletal muscle, and heart muscle and urinary 4-pyridoxic acid (4-PA) excretion were compared. Fasting resulted in a significant increase in PLP concentration in the plasma, liver and heart muscle of rats fed the -B6 diet. Skeletal muscle PLP concentration was significantly decreased in +B6 rats but not in -B6 rats. Following vitamin B6 repletion, PLP concentration in the plasma, liver and heart muscle in previously -B6 rats was similar to the respective concentration in +B6 rats while PLP concentration in the skeletal muscle of previously -B6 rats increased, but it was not reached to that of +B6 rats. At day 1 and 2 of the fast, urinary 4-PT excretion increased in both +B6 and -B6 rats although there was no supply of vitamin B6 due to fasting. These results suggest that vitami B6 is redistributed as PLP when there is a caloric deficit and PLP is supplied by an endogenous source, possibly PLP bound to skeletal muscle glycogen phosphorylase.

In third world countries like Pakistan, the production of electricity has been quickly reduced in past years due to rely on the fossil fuel. According to a survey conducted in 2017, the overall electrical energy capacity was 22,797MW, since the electrical grids have gone too old, therefore the efficiency of grids, goes down to nearly 17000MW. Significant addition of fossil fuel, hydro and nuclear is 64.2%, 29% and 5.8% respectively in the total electricity production in Pakistan. In 2018, the demand crossed 20,223MW, compared to peak generation of 15,400 to 15,700MW as by the Ministry of Water and Power. Country faces a deficit of almost 4000MW to 5000MW for the duration of 2019 hot summer term. Focus on one aspect considering Demand Side Management (DSM) cannot oversea the reduction of gap between power demand and customer supply, which eventually leads to the issue of load shedding. Hence, a scheduling scheme is proposed in this paper called RPSMDSM that is based on selection of those appliances that need to be only Turned-On, on priority during peak hours consuming minimum energy. The Home Energy Management (HEM) system is integrated between consumer and utility and bidirectional flow is presented in the scheme. During peak hours of electricity, the RPSMDSM is capable to persuade less power consumption and accomplish productivity in load management. Simulations show that RPSMDSM scheme helps in scheduling the electricity loads from peak price to off-peak price hours. As a result, minimization in electricity cost as well as (Peak-to-Average Ratio) PAR are accomplished with sensible waiting time.

The purpose of this reasearch is to supply the basic data to improve Home Economics curriculum. This research was intended for 190 home economics teachers who are teaching in Kwang-Ju and chun-nam. The results are summarized as follows； 1. Among the objects of Home economics, the most important objects were to make students understand the significance of family life and development of family numbers. It requires 4 or 5 hours a week to learn these objects. 2. The amount of curriculum was immense and the level of curriculum was higher than students’level. More intencifying field are in this order； sex education, propriety education, consumption life, occupation, and computer education. 3. In home economics curriculum, the main stress was laid upon the application of action and learning content was focused on the matter set in the examination. 4. Theory and practical training classes were usually in the ratio of 7：3 and 8：2 in the current school classes. Ideal training classes are in the ration of 4：6, 5：5, 6：4, which showed that much weight was given to the practical exercises. 5. In practing subject matter, students tended to practice only main subject matter. The reason was primarily due to the lacks of equipments and faccilities, the limitation of training time for enterance examination and budgetary deficit. 6. Application of resorces was in the order of files, realia, samples, hanging chart, O.H.P and V.T.R. 7. The method of evaluation was mostly composed of paper and pens and practical evaluation when the practical evaluation was carrient out, in the case of necessity the standard of evaluation was made out.

The average life expectancy has continuously increased with the development of medical industry. As women get older, they experience the deficit of estrogen caused by decreased function of ovarian. Specifically, they suffer from temporary fever because of unstable vasomotion and, in the long term experience, degeneration of urogenital organs, tooth loss, arteriosclerosis, demantia, snores and so on. Because of these symptoms the estrogen medical supply is getting required. Along with this, many studies have conducted to find out substitutional medicals without any side effects. This research was carried out to find out such substitutable materials. For the purpose of study, we examined the change of estrogen using the rats fed with the pupa powder immediately before the eclosion, eclosed adult, the pupa extract immediately before the eclosion, and the silkworm powder prepared at $3^{rd}$ day of $5^{th}$ instar. The result showed no significant chance in weight, feeding and water intake quantity among variables. However, the estrogen hormone secretion effects was very high at 73 pg/ml in the rats fed with the freeze-dried powder of the Yeonnokjam male pupa prepared immediately before the eclosion, compared with the control at 59 pg/ml. The next was Yangwonjam male adult at 71 pg/ml.

Background: Stroke is a neurological disorder characterized by brain tissue damage following a decrease in oxygen supply to brain due to blocked blood vessels. Reportedly, 80% of all stroke cases are classified as cerebral infarction, and the incidence rate of this condition increases with age. Herein, we compared the efficacies of Korean White ginseng (WG) and Korean Red Ginseng (RG) extracts (WGex and RGex, respectively) in an ischemic stroke mouse model and confirmed the underlying mechanisms of action. Methods: Mice were orally administered WGex or RGex 1 h before middle cerebral artery occlusion (MCAO), for 2 h; the size of the infarct area was measured 24 h after MCAO induction. Then, the neurological deficit score was evaluated and the efficacies of the two extracts were compared. Finally, their mechanisms of action were confirmed with tissue staining and protein quantification. Results: In the MCAO-induced ischemic stroke mouse model, WGex and RGex showed neuroprotective effects in the cortical region, with RGex demonstrating superior efficacy than WGex. Ginsenoside Rg1, a representative indicator substance, was not involved in mediating the effects of WGex and RGex. Conclusion: WGex and RGex could alleviate the brain injury caused by ischemia/reperfusion, with RGex showing a more potent effect. At 1,000 mg/kg body weight, only RGex reduced cerebral infarction and edema, and both anti-inflammatory and anti-apoptotic pathways were involved in mediating these effects.

An increasing global population requires a greater food supply, and accordingly there is demand for enhanced production of rice, as a major crop plant that covers half of the world's population. Rice production in arid area is extremely difficult due to poor soil fertility, salinity, deficit of irrigation water, and weather conditions. The aim of the present study was to determine whether various fertilization recipes could provide a countermeasure to allow rice production while also providing soil amendment such as soil pH adjustment. The study was conducted at an experimental field of the United Arab-Emirates (UAE) from January to April, 2022. Rice seedlings (cv. Asemi, alkaline-resistant) were transplanted in plastic containers, and different types of water and nutrient managements were employed as follows: water management (flooding and aerobic for NPKs treatment group) and nutrient management (NPKs, slow release fertilizers [SRFs] and SRFs + NPK-1 treatment groups with flooding). Water and nutrient management did not show any effect on soil pH adjustment. Rice growth was significantly enhanced in the flooding compared to the aerobic condition, whereas the effect of nutrient management clearly differed among the treatment groups, with SRFs + NPK-1 showing the best results followed by SRFs and NPKs. Most of the fertilization groups markedly accumulated soluble sugars in the shoots and grains of rice plants, but concomitantly a decrease in the roots. Overall, the level of starch showed a tendency of relatively slight perturbation by fertilization. Taken together, the results indicate that soil physical structure should be preferentially amended to find the key for suitable rice production.
