Essential oils aims to rejuvenate and beautify medical skin care the body through the use of essential oils, and generally to improve our outward appearance. Much of this section fouses on the different methods by which essential oils can be used to improve the complexion or to treat specific medical care skin conditions. Beauty, however, is not just skin-deep. The condition of the medical care express the overall health of an individual. A relaxed attitude, together with a well-balanced diet, enough exercise, and a daily intake of plenty of spring water or herbal teas, all help to keep the system in top condition. Essential oils is a healing art which has powerful effects on both mind and body. The vital element in essential oils is the pure oils which are extracted from various part of different plants. The key to medical aromatherapy care lies in its dual use of essential oils and medical care massage, thus masking full use of two of our most important senses-smell and touch. Medical aromatherapy care is holistic, working mainly on the nervous system and including the head and body as part of the same treatment. Using pressure points along the spine, Medical aromatherapy care on the autonomic nervous system and has an immediate effect of relexation. In directly it also acts on mood. Many of the medical massage movements help lymphatic drainage. Essential oils have many different qualities; they can be relaxing or invigorating and are generally antisepic and antibacterial. Medical aromatherapy care can have psychological benefits. The power of essences in healing has been recognized in the treatment of insect bites. Clove, thyme, sandalwood, and lavender are a few of the essences that have antiseptic. Essential oils effect the dry skin for small visual pores, dull matte finish, rough sandy feeling, tantskin. Essential oils effect the mature/sun damaged skin for some red or couperose areas, loose saggy skin, exposure to a lot of ultraviolet light. Essential oils effect the medical care nomal skin good elasticity, healthy color(good circulation), smooth terture.

In this paper, we analyze the adjacent interference between WCDMA and M-WiMAX systems in the 2.6GHz Band under the SISO (Single Input Single Output) configuration. The interference scenarios are characterized into 8 scenarios with different victim and interfering links. Among the 8 scenarios, we find that the most performance loss is observed in the scenarios of victim uplink suffering interference from downlink in both systems. Besides, guard band is applied to mitigate the adjacent interference in all the scenarios. Especially, we reveal that M-WiMAX system is much more sensitive to adjacent interference than WCDMA system due to the lower transmission power. In this paper, we consider the worst interference environment, where interferers always transmit with the maximum power, a loose spectrum mask is adapted, and no additional channel fitters are equipped in both systems.
Fine particulate matter (FPM; diameter ≤ 2.5 ㎛) is frequently found in metropolitan areas due to activities associated with rapid urbanization and population growth. Many adolescents spend a substantial amount of time at school where, for various reasons, FPM generated outdoors may flow into indoor areas. The aims of this study were to estimate FPM concentrations and categorize types of FPM in schools. Meteorological and chemical variables as well as satellite-based aerosol optical depth were analyzed as input data in a random forest model, which applied 10-fold cross validation and a grid-search method, to estimate school FPM concentrations, with four statistical indicators used to evaluate accuracy. Loose and strict standards were established to categorize types of FPM in schools. Under the former classification scheme, FPM in most schools was classified as type 2 or 3, whereas under strict standards, school FPM was mostly classified as type 3 or 4.

To study the effects of surface structure of fiber on the decrement of fatty soil removal at high temperature, the following variables were selected: controled and alkali-treated P.E.T.(polyester) fabrics and chopped fibers as substrates to estimate the detergencies, different aging methods of soiled substrates, and different washing temperatures and surfactant solutions. Radiotagged tripalmitin was used as soil and the detergency was estimated by means of liquid scintillation counting method. The results were as following: The surface of the fiber became rough with many grooves and the hydrophilicity of the fiber was increased and the structure of the fabric became loose by alkali treatment. While the detergency of alkali-treated P.E.T. fabric was better than that of controled P. E. T. fabric, there was no significant differences between the detergencies of controled and alkali-treated chopped fibers. These results indicate that the increment of detergency of alkali-treated P.E.T. fabric is mainly resulted from the changes of fabric structure and the improved hydrophilicity of fiber by alkai treatment. The detergency of tripalmitin was increased with elevating temp. below the m.p. of tripalmitin, was decreased around the m.p., and again was increased above the m.p ..It is considered that the decrement of detergency around the m.p. is due to the diffusion of molten tripalmitin into the grooves on fiber surface, the inner part of fiber, and between fibers. When controled and alkali-treated soiled fabrics and soiled chopped fibers were washed in the distilled water and in the Na-DBS solution respectively, below $60^{\circ}C$ detergencies of alkali-treated fabrics and chopped fibers were improved. However above $60^{\circ}C$ this result was reversed. Therefore these results are regarded as the effects of grooves on fiber surface at high temp. and improved hydrophilicity at low temp. by alkali treatment. When controled and alkali-treated soiled fabrics and soiled chopped fibers were hot-aged before washing, the detergencies of both species were decreased generally. Because the soil was diffused into the grooves on fiber surface, the inner part of fiber, and between fibers during hot-aging. The detergencies of hot-aged species were also decreased above certain temp.. These results suggest that the decrement of detergency at high temp. be resulted not only from the diffusion of soil into the grooves on fiber surface, the inner part of fiber, and between fibers, but also from the characteristics of surfactant solutions.
The style of different styles of clothing have been developed by not only the natural environment and social effects. but also by various variables such as the peculiar cultures and religions of different ethnic groups. It is naturally accepted without question that the origin of trousers was derived from the Skytie race in the modern style of dress. And the style of those trousers has changed and developed throughout a long history in different environments and surroundings. As part of the research of the process in this styles of clothing, it is essential to know how the fabric of trousers has been developed and how the styles have been changed because of different weather conditions and different religions. Nowadays, Eurasian countries was scattered from western and eastern Asian countries to middle Asian countries such as Russia, Uzbekistan, Kazakistan, Turkey, Turkmenistan, Iran and China. These countries are located on the way to the Silk Road. They are fully developed in a cultural area among the different religions. In terms of cultural aspects within the different religions, men's trousers had developed the traditional style of this dress as one of the importnat items on the cultural basis. The ranges and types of these traditional trousers are divided by the regions, such as west and southern Asia, central Asia and China. Pakistan, Afghanistan, Iran, Iraq, Syria, Lebanon, Turkey. Jordan, Saudi Arabia, Kuwait and Israel was a part of the west and southern Asian countries which were located between western countries and eastern countries. This tribes wore Shalwar trousers which is a wide style of trousers. Shalwar in the western and eastern Asian region has a specific feature by the each nation but has the same distinctions such as by using very wide and loose style and tying a fine thread around the waist. Some central Asian countries consisted of part of China, Turkmenistan. the Republic of Tajikistan. the Republic of Kyrgyzstan and the Republic of Afganistan. These style of trousers are compound types which appeared with mixing Draperian Greek culture. So it can be inferred from this data that the horse-riding nomadic trousers which had been handed down from Skytie tribe through Persia. The style of the trousers in those regions has small pieces. The style of the trousers in China, which is located on the way to the far eastern countries, has developed new trousers put together two pieces of the textile. These widen trousers can be worn by using a sash belt. So we can find out that those trousers of countries which mentioned above have a common point and a rule.
Three prototype chestnut harvesters were constructed and evaluated their chestnut collection ability and field efficiency. Air-lock paddle system successfully picked up all loose material, and pick up efficiency was about 56 kg/h. Power required to operate this system was evaluated to be 8.7 kW with an air flow rate of $32.6\;m^3/min$. A radial blade type blower with 0.41 m impeller diameter was considered to be a minimum size for this system. For the auger system, air was sucked into the cylinder as the hinged flat cover began to be opened by the material pushed by the auger, and the empty burrs flew back to the container through the space between auger flights and collected in the bottom of the container. It was considered to add a device to prevent air from flowing back or to use the back flowing air for separation of burrs and nuts inside the container. The venturi system could not pick up chestnuts, as they only carried part way up to the suction hose. Consideration was given to an idea that the venturi could be used as a cleaning and separation mechanism for containers filled with both empty burrs and good nuts. A minimum vacuum of 129 mm wg was required to pick up chestnuts, and the corresponding inlet air velocity was 19.3 m/s. 104 mm of vacuum, which was about 81 % of that required for nuts, was enough to pick up burrs with nuts inside. Also, empty burrs with higher moisture content recorded the same pressure as for the burrs with nuts.
This research used a questionnaire to provide basic data for the design of dressing form that enables the manufacture of senior menswear with an improved fit to match the dissatisfaction with the fit of male suits over the 50s. We used 132 questionnaires as analytical data. The results were: The item 'purchasing method of formal suits' showed that 95.5% purchased ready-to-wear jackets. The 'abdominal obesity type' and 'trunk waist type' had a high frequency of 'complaints about the size of the ready-to-wear jacket'. They choose their suits and wear them directly from the store. It is expected that senior males will complain about ready-to-wear formal suits due to the increase in girth item than normal type due to change of body shape since they consider size to also be important when purchasing suits. The most important part of the body when purchasing suits is the shoulder area, followed by the front width and back width of the fit. As for the degree of recognition of suit size, 38.1% said that they know the size and 'Suit size is hard to understand'. As a result of dissatisfaction with formal dressing, the items of 'Neck wide of get loose', 'Drag line of back neck', 'Not fit of front opening', 'Not fit of shoulder slope' and 'dissatisfaction'. Therefore, it is salient to establish suit fitting system and size system for senior men.
A wide variety of pathogens are known io be seedborne, carried either as infectious mycelium internally or as contaminants on the seed coat. When seed is infected with a pathogen, the seed nay be rendered nonviable or it may remain viable but produce weak seedling. In some cases, the Infected seedling nay not be severely weakened, but nay serve as a source of primary inoculum within a community of plants. A recent problem nay be the dissemination of seedborne pathogens occurring as a result of the massive movements of seed, as a part of the 'Green revolution' Disease of great danger to agriculture may be introduced with seed from other parts of world. Seed treatment with organic mercury compounds in liquid form had become popular since about 1955. Organic mercury compounds contributed considerably to the increase in production of many crops and vegetables. In 1975, however, the use of organic mercury compound was forbidden because of doubts regarding their residual mammalian toxicity in agricultural products. Benomyl-thiram mixture, thiophanate methyl-;hiram mixture and TCMB have now been registered as seed disinfectants for the use of rice blast, brown spot and Bakanae disease. Oxathiinsthiram mixture has been registered as seed disinfectant for barley and wheat loose smut and leaf stripe of barley. Agricultural techniques have made such rapid progress that the nursery methods changed from the use of paddy nursery to box nursery designed for machine-transplanting. The spread of rice transplanting machines has caused increase of seedborne diseases. Among seedborne diseases, Bakanae disease has remarkably increased and causes much damage recently. In order to counter this trend, seed disinfectants must also be diversified. First, effective non-selective disinfectants need to be developed, and second, appropriate control methods always need to be prepared in parallel with the development of new techniques for cultivation.
Thirty-six Najdi ram lambs, weighing an average of 24 kg and circa 3 months old, were utilized in this trial to evaluate the effects of various alfalfa hay particle lengths in the diet on growth performance, digestion coefficients, nitrogen retention and carcass characteristics. Lambs were randomly allotted to three dietary treatments: 9.5 and 14 mm diets, where alfalfa hay was processed to 9.5 and 14 mm particle lengths, respectively, mixed with 3 parts of concentrate and pelleted as a total mixed ration (TMR), and long hay diet, where one part of loose alfalfa hay (17.8${\pm}$2.4 cm) was offered in combination with 3 parts of only-concentrate pellet. All dietary treatments were homogeneous in their ingredient composition. All lambs were slaughtered after a 14-week feeding trial. Although the results showed no significant effect of hay particle length on DMI, TDN and DCP, lambs fed the 9.5 mm pelleted diet had higher (p<0.05) final body weight, ADG, gain efficiency and nitrogen retention than lambs fed the 14 mm and long hay diets. Altering the particle length of alfalfa hay in diets did not affect the digestibility of DM or CP, whereas digestibilities of ADF and NDF were 3.7% and 5.4% higher (p<0.05), respectively, for the long hay diet versus the 9.5 mm pelleted diet. Hot carcass weight, percentage of separable lean from the $9-11^{th}$ rib joint, and percentages of protein and EE in the separable lean increased (p<0.05) as the particle length of alfalfa hay in the diet decreased. Under the conditions of this study, the reduction of particle length in the TMR played an important role in enhancing performance without altering DM consumption, and this may lead to more efficient productivity of lamb fattening compared with longer chopping lengths.
The purpose of this study is to investigate difference and likeness on the form in women's Hanbok between the later Chosun Dynasty and modern times based on Belong's observing system for 'Apparel-Body Construct'. Belong's framework is composed 5 pairs of contrast word -'Closed or Open', 'Whole or Par', 'Planar Separation or Planar integration'. 'Flat or Rounded', and 'Determinate or Indeterminate'. Major findings of this study are as follows. First, the form of women's Hanbok in later Chosun Dynasty is 'Variably Closed', 'Part' and 'Rounded', whereas that in modern is 'Open', 'Whole' and 'Flat' Women's Hanbok of modern is lesser convex, and more open than that of later Chosun Dynasty according to increasing use of transparent textiles. Moreover, in comparison with old style, that of modern has the tendency of perceiving primarily whole feature by organic linkage of parts. Because of loose fit of Jeogori and rigid DongJong etc, characteristic of 'Plat' strengthened in modern Hanbok. Secondly, women's Hanbok in the later Chosun Dynasty and modern has common properties of 'Planar Seperation' and 'Determinate'. Women's Hanbok belongs to 'Planar Seperation', because the effect cognized to figure and ground. can be found between small parts and whole of Jegori, or can be found between the head and face. Jeuori and waist band, and Chima and under ware. Further more. it can be classified into 'Determinate'. because it use textiles which have no pattern un it or which show a subtle surface effect by texture changing.
