Kim Deuk-yeon(金得硏), who lived at the age of Chosun Dynasty, was the person who kept the parents's will of not serving as a government officias even though he had the ability of serving those positions. He made his composition at the Jisujeong(止水亭), a kind of pavilion which he had built, and the Sijo(時調) Sanjungjapgok(山中雜曲) is one of those compositions. This sugggestes that Sanjungjapgok has a close relation with the Jisujeong(止水亭) which he opreated on his own. So the purpose of this study is focused on analyzing the Sanjungjapgok based on his goal of operating the Jisujeong. The middle age of Chosun dynasty was the era when the pavilion had been prevail even to the average aristocrats who stayed just in local area. Kim Deuk-yeon seems to have had a great endeavor of operating his own pavilion; he had prepared to build Jisujeong for about 30 years. This resulted in his affection of the Jisujeong, which caused him to spend the last part of his life there. Sanjungjapgok consists of 49 pieces of peom and seems to have been written after compositing Jisujeongga(止水亭歌). Even though it has the same title, it doesn't have lots of relations for us to regard this as a Yeonsijo(聯詩調). But this also has the properties of Yeonsijo, whoch contatins 14 Yeonjaksijo(聯作時調) composed of Yeonsijo which has 2 to six lines. The subject of the Sanjungjapgok can be classified as a four major parts: appreciating the nature, study, gathering to make the poem, and taking a rest while satisfied with his own situation. These four properties reflect the function of the private pavilion. In the light of these four properties, I noticed that there were some contents dealing with the private pavilion. Given his social status, I was able to confirm that he had the considerable satisfaction with his life of operating the private pavilion, which was reflected by the Sanjungjapgok.

Trauma to any nerve may lead to persistent paresthesia. Trauma to the nerve sheath can be produced by the needle. The patient frequently reports the sensation of an electric shock throughout the distribution of the nerve involved. It is difficult for the type of needle used in dental practice to actually sever a nerve trunk or even its fibers. Trauma to the nerve produced by contact with the needle is all that is needed to produce paresthesia. Hemorrhage into or around the neural sheath is another cause. Bleeding increases pressure on the nerve, leading to paresthesia. Injection of local anesthetic solutions contaminated by alcohol or sterilizing solution near a nerve produces irritation; the resulting edema increases pressure in the region of the nerve, leading to paresthesia. Persistent paresthesia can lead to injury to adjacent tissues. Biting or thermal or chemical insult can occur without a patient's awareness, until the process has progressed to a serious degree. Most paresthesias resolve in approximately 8 weeks without treatment. In most situations paresthesia is only minimal, with the patient retaining most sensory function to the affected area. In these cases there is only a very slight possibility of self injury. But, the patient complaints the discomfort symptoms of paresthesia, such as causalgia, neuralgiaform pain and anesthesia dolorosa. Most paresthesias involve the lingual nerve, with the inferior alveolar nerve a close second. This is the report of a case, that had the persistent paresthesia care on left lingual & buccal shelf regions after the lingual and long buccal nerve block anesthesia.

Purpose: As our population ages and becomes an elderly society the number of elderly care hospitals is rapidly increasing. Because physical functions and spatial perception in the elderly decrease with age, these hospitals require more systematic and intelligent space designs. The design of these spaces are even more complex because they must accommodate medical programs to treat various different diseases and ailments and also because there are many first time patients and irregular short term patients that seek out outpatient treatment services. Also by analyzing the spatial configuration systems and systematic relationships between each of the functional spaces of the outpatient treatment service departments for hospitals specialized in care for the elderly by focusing on the hallway and corridor systems of these hospitals, the according characteristics and trends were examined. Methods: Based on preceding research, the types of hallway and corridor systems of these hospitals were categorized into five types, including gallery corridors, middle corridors, hall-type, mixed type and cyclic type corridors, and into six types according to function including by medical diagnosis, patient registration, examination, administration and convenience and shared common space to derive any interconnecting relationships between the corridor systems. Also by comprehensively examining the types and combined utilization of the corridor types and the integration and the intelligibility of the space syntax, any trends within the corridor system were derived. The elderly care hospitals examined in this research study were twelve hospitals that opened after the year 2000 in Korea with more that 150 sick beds with areas larger than $1000m^2$ and with all outpatient medical service related rooms located entirely on a single floor of the hospital. Results: The following results could be confirmed based on this research study. 1) The spaces where medical diagnosis and examination occurred were adjacent, and the movement lines for first time patients and re-visiting patients were taken into consideration by separating the treatment space. 2) This research study confirmed that the larger the size of the hospital was, there were more detailed categorizations of treatment services and that there was a tendency for treatment areas to be separated and independent from examination areas. 3) There was a tendency for integration and intelligibility to decrease the more complex and diverse the combination of hall types designed into the corridor systems of these hospitals was. cyclic type corridors dramatically decreased the intelligibility of the corridor systems of these hospitals. 4) The priority rank of these spaces were confirmed to be highest in the order of registration, diagnosis, examination, treatment, administration and shared common spaces. However it was confirmed for the local integration that the diagnosis scope had the highest priority rank. Implications: There were exceptional cases confirmed where the number of unit spaces did not have an absolute effect on integration and intelligibility. These results can be interpreted to mean that this can be overcome through efficient architectural planning.

This paper presents the effects of RF performance parameters on the Galileo receiver design via simulation after reviewing the requirements of the Galileo receiver structure. At first, we considered the general requirements, structure and characteristics of the Galileo system. Then we designed the Galileo receiver focused on performance requirement of 16 dB C/N which is equal to 15 % Error Vector Magnitude(EVM) by using Advanced Design System(ADS) simulation program. In order to verify the function of Automatic Gain Control(AGC)), we measured the IF output power level by changing the input power level at the front - end of the receiver. We analyzed the performance degradation due to phase noise variations of Local Oscillator(LO) in the Galileo receiver through EVM when the minimum sensitivity level of -127 dBm is applied at the receiver. We also analyzed the performance degradation according to variable Analog-to-Digital Converter(ADC) bits within the Dynamic range, -92 ~ -139 dBm, which has been defined by gain range (-2.5 ~ +42.5 dB) in the AGC operation. The results clearly show that the performance of the Galileo receiver can be improved by increasing ADC bits and reducing Phase Noise of LO.

The Campus Core is centered at the physical, functional and symbolic environment of a university, which is known as the top academic institution, hence it metaphorically represents not only the educational philosophy when institution first opened, but also the transformed values of the time. Today, universities are asked to actively communicate with the local community in terms of function and be remodeled as pedestrian-friendly campuses in terms of physical environment. For this reason, the study comprehends the concept of the campus core in accordance with a pedestrian-friendly environment and suggests a practical plan for campus cores of district national universities based on previous research examination. Since the purpose of the study is to suggest a change in the circulation system centered on vehicle use to transform into a pedestrian-friendly environment through a planned approach while introducing public mixed-use at the same time, the study supports the fact that it is possible to reorganize the strategy of a pedestrian-friendly circulation system and partially revise the land utilization to yield the expected outcomes. Thus, this study will provide valid suggestions for similar maintenance plans while looking back to the meaning and value of today's campus core.

We study free vibration analysis of sigmoid functionally graded materials(S-FGM) nano-scale plates, using a nonlocal elasticity theory of Eringen in this paper. This theory has ability to capture the both small scale effects and sigmoid function in terms of the volume fraction of the constituents for material properties through the plate thickness. Numerical solutions of S-FGM nano-scale plate are presented using this theory to illustrate the effect of nonlocal theory on natural frequency of the S-FGM nano-scale plates. The relations between nonlocal and local theories are discussed by numerical results. Further, effects of (i) power law index (ii) nonlocal parameters, (iii) elastic modulus ratio and (iv) thickness and aspect ratios on nondimensional frequencies are investigated. In order to validate the present solutions, the reference solutions are compared and discussed. The results of S-FGM nano-scale plates using the nonlocal theory may be the benchmark test for the free vibration analysis.

Recently, natural disasters, which are hard to predict and prevent, are rapidly increasing due to climate change worldwide. Particularly the damage scale of urban areas is increasing because of local torrential rainfall. In urban areas, the rain water cannot flow to pipes well due to the high percentage of impervious areas by the indiscriminate development. As a result, the inundation damage is getting higher in urban areas. So we need to characterize the interception of the grate inlets to ensure good drainage in impervious areas. But Korean installation criteria of grate inlets does not reflect road and drainage sector characteristics so the grate inlets do not function properly in many areas. In this study, we suggest the interception capacity equations about grate inlets through hydraulic experiments in various conditions. Therefore, the interception capacity changes are analyzed according to bearing bar slopes of grate inlets, grate inlet sizes and shapes and connecting pipe numbers. Though this, we developed the interception capacity equations about domestic grate inlets.
