The Taq-i Bustan reliefs are representative works from the Sassanian dynasty of the 4th to 7th centuries. This study analyzes the costumes depicted in the Taq-i Bustan reliefs to gain understanding of the phenomena of cultural exchange between the East and West by observing the foreign cultural elements appearing in the Sassanian costumes of that time. Literature study and artifacts analysis were conducted in parallel. External elements appearing in Taq-i Bustan's costume were Greek-Roman and Central Asian. The tunics and trousers of the gods and the trousers of kings (Ardashir II, Shapur II and Shapur III) were made of thin fabric and showed many wrinkles, a characteristic of Greek and Roman clothing. On the spandrel above the arch of the great grotto of Khusrau II are depicted the goddesses of Victory, in a Greco-Bactrian style. Among the costume elements of Taq-i Bustan, there were also Central Asian elements observed. One Central Asian costume element was the round clasp ornament for tying the trousers. The side slits and hem of the tunic were presented in the style of the Sogd clothing of Central Asia in the 6th and 7th centuries, while the pearl rounded pattern was activated in Sogd, Kucha and Kizyl in the 7th and 8th centuries. These reliefs are considered important evidence of eastern influences in Sassanian culture.

Purpose: This study aimed to assess the quality of life (QoL) of children with glycogen storage disease (GSD) and their parents and to determine the impact of myopathies. Methods: A prospective case-control study was conducted at the Cairo University Children's Hospital and National Liver Institute, Menoufia University. A promising new style of questionnaire called the Stark Quality of Life Questionnaire was used to assess the quality of life. Results: Fifty-two children diagnosed with GSD (cases) and 55 age- and sex-matched healthy children (controls) were included. A statistically significant difference was found between cases and controls regarding food intake; mental behavior parameters such as mood, energy, and social contact; and physical behavior parameters such as running and tying shoelaces. Children with myopathies had significantly lower QoL scores in most of the parameters. Conclusion: GSDs alter children and their parents' mental and physical abilities. Lower QoL scores were detected in children with both skeletal myopathy and cardiomyopathy, but the difference was not statistically significant when compared with the children without myopathies.

Without scrutinizing reflection, the plasma comprising a coronal loop is usually regarded to reside within a flux rope. This picture seems to have been adopted from laboratory plasma pinches, in which a plasma of high density and pressure is confined in the vicinity of the flux rope axis by magnetic tension and magnetic pressure of the concave inward magnetic field. Such a configuration, in which the plasma pressure gradient and the field line curvature vector are almost parallel, however, is known to be vulnerable to ballooning instabilities (to which belong interchange instabilities as a subset). In coronal loops, however, ideal MHD (magnetohydrodynamic) ballooning instabilities are impeded by a very small field line curvature and the line-tying condition. We, therefore, focus on non-ideal (resistive) effects in this study. The footpoints of coronal loops are constantly under random motions of convective scales, which twist individual loop strands quite randomly. The loop strands with the axial current of the same direction tend to coalesce by magnetic reconnection. In this reconnection process, the plasma in the loop system is redistributed in such a way that a smaller potential energy of the system is attained. We have performed numerical MHD simulations to investigate the plasma redistribution in coalescence of many small flux ropes. Our results clearly show that the redistributed plasma is more accumulated between flux ropes rather than near the magnetic axes of flux ropes. The Joule heating, however, creates a different temperature distribution than the density distribution. Our study may give a hint of which part of magnetic field we are looking to in an observation.

As the world's attention turns to sustainability and the considerations of cumulative effects, the concept of Strategic Environmental Assessment(SEA) has become more significant and urgent and increasing number of countries and international organizations now undertake some forms of SEA. The term SEA, however, is variously defined and understood; generally it means a formal process of systematic analysis of the environmental effects on development policies, plans, programmes and other proposed strategic actions. This process extends the aims and principles of EIA upstream in the decision-making process, beyond the project level in which major alternatives are still open. There is a shift toward more integrative approaches and greater use of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) as sustainability tools in cooperation with Environmental Management System (EMS). Currently, Korea has EIA system and Prior Environmental Review System (PERS) which is different type of SEA as Environment Assessment (EA) system. APEMI IA MODEL integrated following three pillar(refer to attached figure.1) ; First pillar symbolized decision making cycle with planning process. Second pillar symbolized integrated assessment which tying SEA and EIA with specific impacts assessment(eg: social impact assessment, economic impact assessment, health impact assessment etc) in cooperation with EMS. Third pillar symbolized EA best practical procedure of International Association for Impact Assessment(IAIA). Considering the above, we applied new conceptual model(APEMI IA MODEL) into Impact Assessment for better integrated decision-making in KOREA as an alternative IA system(IS IA MODEL A and B refer to attached figure 4, 5).

Development of the yarn sorting equipment (khonhook) by slide way due to the principle of engineering that cause of workers on the long of motion time. The data was collected from the weaving group Ban Nongkok village, Nakornratchasima Province, THAILAND. According to the study, the step of yarn sorting (konhook) was one of the steps that affect long of motion time. The problem was the inadequate capacity equipment. The objective of research was to study and develop the yarn sorting equipment (konhook). The fabric used in the study was 64 meters in length and 1 meter in width. Researchers studied the processes the yarn sorting (konhook) which it consists of seven sub steps, 1) the thread tube setting, 2) yarn bunching, 3) tying a knot at the end of yarn, 4) looping the yarn into a pillar, 5) sorting the yarn (konhook), 6) crossing pillars and 7) taking out the yarn. Researchers focused on studying yarn sorting process (konhook) by designing and creating a device for yarn sorting (konhook) for reducing yarn sorting (konhook) time by the original method performance indicators. The results found that the developed yarn sorting equipment (konhook) ) by slide way could reduce working time from 7.24 minutes to 6.08 minutes of the original equipment yarn sorting (konhook). This means it could make the process 16.02 % faster. This also helps reducing the distance of workers' movement from 2,234 meters to 8 meters. This is 99.64 % shorter.

The purpose of this study was firstly to identify how the characteristics of children(grades, birth order, self-consciousness), parents(age, educational level, employment status of mother, mother's parenting behavior), and context (private tutoring status, tying area) relate to children's stress and secondly to examine the relative effects of these variables on children's stress. The subjects of this study were 940(453 boys, 440 girls) children from grades 4 to 6 who were selected from three elementary schools in Seoul and Buchun. Data were analyzed with t-test, correlation, and multiple regression analysis. The results were as follows: (1) Girls get stressed easier than boys in terms of being treated distantly by their friends. (2) The study showed a negative relationship between children's stress and their self-consciousness such as general self-consciousness, teaming self-consciousness and total self-consciousness. (3) While the results showed a negative relationship between children's stress and mothers' acceptable behavior, the study revealed a positive relationship between children's stress and the mother's over protective behavior which in turn raised the children's stress level. (4) In 'total stress', it was recognized that boys were affected mostly tv grades in the children's variables category, while girls were affected by their general self-consciouness. In addition, both girls and boys were affected mostly by acceptable-refusal parental behavior in the parental variables category, and further affected by the living area in the category of conditional variables.

We present the design of a radiometer in W-band which operates simultaneously with a single antenna configured FMCW radar. We choose a total power radiometer(TPR) which shares an antenna and a front-end with the radar for miniaturizing the system. We separate the radiometer signal from the radar signal using a diplexer in IF band. Because the radiometer has an unwanted transmitter section due to the common use of the MMW front-end with the radar, some additional noise signals caused by the transmitter degrade the sensitivity of the radiometer system. To compensate the degradation of sensitivity, we use matching circuits and a diode detector configured as the voltage doubler. Through some experiments, we have verified that the designed radiometer system has good performances in detecting metal targets tying at several hundred meters.

Korea's traditional hanok houses are roughly divided into tiled-roofed, thatched-roofed, shingle-roofed, and oak bark-roofed houses according to their materials. In thatched-roof houses, there are various styles according to regional characteristics regarding building materials, slope, shape, and tying method. Unfortunately, as the number of thatched-roof houses have been rapidly decreasing since industrialization, it is difficult to find these characteristics of traditional houses. The study revealed that there was a roofing material a higher percentage of houses with thatched roofs than houses with tiled roofs. Furthermore, the plane occupies a large number of left and right protruding types and layered types, and there is no partition wall between Jeongji and maru. In addition, the opening in the front has characteristics of the Northern region that is responsible for lighting and ventilation, not for access. In the case of thatched-roof houses in Goseong Wanggok Village, the field survey suggests that a high percentage of buildings can recover their original characteristics.

In this research, the frost heave mechanism of the weathered tuff soil sampled from the area tying between Ulanbator and Beijing was studied. The frost heave tests were carried maintaining the constant temperature at both upper$(+5^{\circ}C)\; and\; lower(-5^{\circ}C)$ ends of the sample. Here, main emphasis is given on variation of the freezing point depression with the variation of applied overburden pressure. The expansion of ice lens and migration of the pore water towards freezing front were observed in the test. It was found that with the increase in overburden pressure there is decrease in heave rate and increase in the absolute value of a segregation-freezing temperature. Hence the equation between segregation-freezing temperature and overburden pressure could be suggested. Also the water content of the samples at the frozen side was shown to be higher than those at the unfrozen side. Similarly, the water at warmer part of the frozen tuff was found much higher than that of the cooler part.

In order to investigate the effects of a decreased activity on skinfold thickness, circumference and muscle strength of the extremities during the recovery period following heart surgery, skinfold thickness, circumference and muscle strength of the extremities were measured on days 0, 3, 6, and 9 following the surgery, and compared with those on the arrival day of intensive care unit. Skinfold thickness was measured using a skinfold caliper(Saehan Cor., Korea), circumference of the limbs were measured with a tape measure, upper extremity strength was determined using the Takei grip dynamometer and lower extremity strength was measured by pressing the flatfoot on an electronic digital health meter while tying on a bed. Results from this study were thus : 1. Skinfold thickness of triceps, quadriceps and gastrocnemius muscle on days 3, 6, 9 following the heart surgery was not significantly different from that of on the day of operation. 2. Circumference of midupperarm and midthigh on days 3, 6, 9 following the heart surgery was not significantly different from that of on the day of operation. Circumference of midcalf on days 3, 6 following the heart surgery was not significantly different from that of on the day of operation, while that of midcalf on day 9 following the surgery decreased significantly compared with that of on the day of operation. 3. Muscle strength of the upper extremity was not significantly different from that of on the day of operation, while that of the lower extremity on day 9 following the surgery decreased significantly compared with that of on the day of operation. From these results, it may be concluded that circumference and muscle strength of lower extremity can be decreased due to the postoperative inactivity following heart surgery in congenital heart disease children.
