Nerve conduction studies help delineate the extent and distribution of the neural lesion. The nerve conduction was studied on upper(median, ulnar and radial nerves) and lower(personal, posterior tibial and sural nerves) extremities in 83 healthy subjects 23 to 66 years of age. and normal values were established(Table 1). The mean motor terminal latency (TL) were : median. 3.6(${\pm}0.6$)milliseconds ; ulnar. 2.9(${\pm}0.5$) milliseconds ; radial nerve. 2.3(${\pm}0.4$) milliseconds. Mean motor nerve conduction velocity(MNCV) along distal and proximal segments: median. 61.2(${\pm}9.1$) (W-E) and 57.8(${\pm}13.2$) (E-Ax) meters per second ; ulnar. 63.7(${\pm}9.1$) (W-E) and 50.(${\pm}10.0$) meters per second. Mean sensory nerve conduction velocity(SNCV) : median. 34.7(${\pm}6.7$) (F-W), 63.7(${\pm}7.1$) (W-E) and 62.8(${\pm}12.3$) (E-Ax)meters per second ; ulnar. 38.0(${\pm}6.7$)(F-W), 63.4(${\pm}7.5$) (W-E) and 57.0(${\pm}10.1$) (E-Ax)meters per second ; radial, 45.3(${\pm}6.8$) (F-W) and 64.2(${\pm}11.0$) (W-E) meters per second ; sural nerve, 43.4(${\pm}6.1$) meters per second. The amplitudes of action potential and H-reflex were also standardized. Mean H latency was 28.4(${\pm}3.2$) milliseconds. And. the fundamental principles, several factors altering the rate of nerve conduction and clinical application of nerve stimulation techniques were reviewed.

We investigated HBV markers in serum and cerebrospinal fluid of 50 subjects with neurologic disorders or other disorders, who visited Dept. of neurology, college of medicine, Yeungnam University, from April-1 to August-31 1994 and were performed cerebrospinal fluid analysis to investigate the detection rate of HBV markers in cerebrospinal fluid and the possibility of neurologic disorders associated with HBV infection. The results were as follows. The positivity of HBsAg and HBV prevalence rate in serum were 6(12.0%) and 37(74.0%). The number of patient with HBsAg, only anti-HBV and no markers were 6(12.0%), 31(62.0%) and 13(26.0%), respectively. The positivity of HBsAg and HBV prevalence rate in cerebrospinal fluid were 3(6%) and 18(36.0%). The number of patient with HBsAg, only anti-HBV and no markers were 6(100.0%), 12(38.7%) and 0(0.0%) respectively. The number of patient with virus associated diseases(VAD) and non virus associated diseases(NVAD) were 26(52%) and 24(48%). The HBV prevalence rate in serum of VAD and NVAD groups were 88.5% and 58.3% (p<0.05). The HBV prevalence rate in CSF of VAD and NVAD groups were 53.8% and 16.7%(P<0.05). The HBV prevalence rate in serum and CSF of VAD and NVAD groups were 60.9% and 28.6%. Aa a conclusion, the HBV markers in the CSF were partially detected at the presence of the HBV markers in serum. The prevalance rate of HBV in the CSF was increased at the HBsAg positive in the serum and the serum and the CSF was significantly increased at the VAD group than the NVAD group.

This paper looks into the Confucius customs of Yiphu and Seungjung, that is respectively a problem of deciding the successor of the family and a matter of establishing Jongtong (宗統: the proper inheritance line of the family), especially concerning the funerary and ancestor memorial services through Seongho Lee Ik's discussion on proprieties, whose Yeahak (禮學: Studies on Proprieties) is representative of the eighteenth century Yeahak. Seongho Lee Ik sees that there is one penetrating principle that should apply the same concerning Jongtong, regardless whether it is for the state or for a family or whether it is for the royal family or for the gentry in or out of the state service. To establish this one penetrating principle, he emphasizes the manners that fit one's circumstance and social standing, proposed as the theory and practice of 'Seoin-garyea (庶人家禮: Proper customs that even common people with no official titles can practice in marking their important life events like coming-of-age, marriage, and death)'. These two aspects of Seongho seem at odds with each other at a glance. Yet given that he considers that keeping proprietary manners for their own social standings would help secure the fundamental social order, which is of supreme importance to him, it makes sense. Next, the most problematic issues about Seongjung and Yiphu are the timing when one can declare the 'absence of the patriarch' and the manner how one substitutes oneself for the absent patriarch. Seongho sees that it is one thing to 'inherit the Jongtong' and it is another to 'become a next patriarch'. Basically, he does not separate the problem of Jongtong by one's social standings. The real situation involved can be different based on one's social standing, he readily acknowledges. Yet, 'the unchangeable ethical principle between the father and the son' would prevail over the same regardless of classes, he insists. This attitude of his is in line with his philosophy of proprieties and his practical guidance that proposes 'Seoin-Garyea' with an appeal to establish fundamental social order based on the practice of proper manners in accordance of one's social standing as he philosophizes the rules of Jongtong on the base of the one penetrating principle.

To clarify the seed germination characteristics among cultivated Perilla crop and their weedy types in Korea, we studied the germination percent and germination energy of 162 accessions (102 cultivated var. frutescens, 41 weedy var. frutescens, and 19 weedy var. crispa) in both conditions of $4^{\circ}C$ low temperature treatment and non-cold treatment. In our study, most accessions of cultivated var. frutescens showed more than 50% in both germination percent and germination energy in both cold and non-cold treatment conditions. Whereas, most accessions of weedy var. frutescens and weedy var. crispa showed lower than 50% in both germination percent and germination energy in both cold and non-cold treatment. In addition, most accessions of Perilla crop and their weedy types showed much higher germination percent and germination energy in $4^{\circ}C$ low temperature treatment condition compared to the seeds under non-cold treatment condition. The information provided in this research may help for our understanding the variation of seed germination characteristics among accessions of cultivated Perilla crop and their weedy types in Korea.

Plug seedlings of vinca (Catharanthus roseus L. 'Pacifica Punch') and salvia (Salvia splendens F. Sellow ex Roem & Schult 'Maestro') were transplanted into square plastic pots (145 mL volume) filled with a soilless growing medium. To determine the effect of application rate on the growing medium EC and growth of plants, 0, 0.5, 1.0, 1.5, 2.0 and 4.0 g per pot of a controlled release fertilizer (14-14-14 Osmocote, 14N-6.2P-11.6K) were mixed with the growing medium. Plants were subirrigated daily with tap water. In both vinca and salvia, growing medium EC increased as application rate was elevated. Growing medium EC was relatively constant over a whole crop period when the application rate was less than 1.5 g per pot, while it decreased throughout the experiment at higher application rates such as 2.0 to 4.0g per pot in both species. The greatest leaf area, plant height, and shoot dry weight of vinca were obtained when plants were fertilized with 2.0 to 4.0 g per pot of the fertilizer, resulting in a growing medium EC of $1.0{\sim}1.7dS{\cdot}m^{-1}$ throughout the experiment. Leaf area, shoot dry weight, and chlorophyll content of salvia increased with elevated application rates. Leaf area, shoot dry weight, and chlorophyll content of salvia were the greatest when plants were fertilized with 4.0 g per pot, resulting in growing medium EC of $1.0{\sim}4.0dS{\cdot}m^{-1}$ throughout the experiment. Plant height of salvia was the greatest when plants were fertilized with 2.0 to 4.0g per pot. Concentrations of nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), and sulfur (S) in the shoots of vinca increased, while concentration of calcium (Ca) decreased with elevated application rates. Concentrations of boron (B) and manganese (Mn) in the shoots of vinca increased as the application rate decreased.

This study investigates the funeral rituals practiced by the Joseon Dynasty as recorded about Lee Mun Geon (1494~1567, a.k.a Mukjae), who mourned by the grave of his deceased mother, Ms. Shin (1463~1535), a woman whose family's origin was Goryeon. The study focuse on the rituals performed by Lee after his mother's death, his participation in the funeral, and his mourning specifically as an individual who has lost his parent. Reviewing Lee's mourning life beside the grave, the contents of diary belonging to a nobleman in the middle of Joseon Dynasty were studied aimsing to find out the meaning of rituals, the overall recognition accorded to death, and the filial duties that were carried out by the noblemen of the time. Although noblemen in the middle of Joseon Dynasty ceaselessly attempted to change the observance of funeral rituals through legislation, it was difficult to change the mindset of the people, who fllowed the deep-rooted traditions of long history. It must be acknowledged that the Joseon Dynasty had a different cultural background than that of China. There was a fundamental problem when they tried to adapt The Family Rituals of Zhu Xi, followed by the Chinese, to the Joseon society. Although The Family Rituals of Zhu Xi emphasized ancestral rites focusing on enshrining mortuary tablets and the importance of establishing the family shrine hundred times, noblemen in the mid-Joseon Dynasty period cared for their parents in the grave by mourning for them than by following such practice. The solemn memorial service held in front of the grave, and the annual ritual service on the death anniversary were far more important to the noblemen in the mid-Joseon Dynasty. Amid such contradictions, the noblemen accepted and performed the mourning rituals beside the grave of their parent. Human beings across the ages have always dwelt upon thoughts of the afterlife. Most people believe that they attain a state after the death of their physicalbody. If humans did not have such thoughts, they would not be bothered if death occurs on being hit by a car on the street. Thus, human beings often think of the ritual services related to death, although in different forms. Therefore, mourning by the grave of their parent held great significance among the noblemen of the Joseon Dynasty as a sign of their filial piety.

Sanjo has a quintessential value not only because of its musical depth but also because of its style of music that best expresses Korean sentiment. However, new values are being established from different viewpoints as time passes so Sanjo's values need a modification in order to encompass a contemporary value that is required and accepted by modern society. In this context, while focusing on communication with the public, I contemplated the developmental direction of Sanjo in five perspectives; The Social realization of value, The Experimental and social transformation, The Social diffusion of creation, The Leap of fusion and harmony and finally The Socialization of contents. In the perspective of 'social realization of value', Sanjo refers to creative activity as a new 'duneum' which allows traditional and creative activity to deviate freely while still being under the Sanjo guideline. Either way, it has a periodical value because new forms with new rhythms are the only ways to communicate with the modern public. When these values can be understood by modern society can Sanjo be revived and be acknowledged as an infinite value. Secondly as an experiment and social transformation, there is a transformation of musical instruments in the 21th century. Our musical instruments should be transformed to effectively perform our music rather than to perform Western music. Third, social diffusion of creation should be the 'new Sanjo festival in 21th century' which can facilitate the communication with the public. Fourth, regarding leap of fusion and harmony, I suggest a performing culture consisting of 'Storytelling Sanjo' and 'Media Art' which will ceaselessly evolve Sanjo performance as a medium to communicate with the public. Finally, in regards to the socialization of contents, I emphasize that Sanjo should have contents of mass media as a way of means to help utilize mass media.

Sea surface wind is a fundamental element for understanding the oceanic phenomena and for analyzing changes of the Earth environment caused by global warming. Global research institutes have developed and operated scatterometers to accurately and continuously observe the sea surface wind, with the accuracy of approximately ${\pm}20^{\circ}$ for wind direction and ${\pm}2m\;s^{-1}$ for wind speed. Given that the spatial resolution of the scatterometer is 12.5-25.0 km, the applicability of the data to the coastal area is limited due to complicated coastal lines and many islands around the Korean Peninsula. In contrast, Synthetic Aperture Radar (SAR), one of microwave sensors, is an all-weather instrument, which enables us to retrieve sea surface wind with high resolution (<1 km) and compensate the sparse resolution of the scatterometer. In this study, we investigated the Geophysical Model Functions (GMF), which are the algorithms for retrieval of sea surface wind speed from the SAR data depending on each band such as C-, L-, or X-band radar. We reviewed in the simulation of the backscattering coefficients for relative wind direction, incidence angle, and wind speed by applying LMOD, CMOD, and XMOD model functions, and analyzed the characteristics of each GMF. We investigated previous studies about the validation of wind speed from the SAR data using these GMFs. The accuracy of sea surface wind from SAR data changed with respect to observation mode, GMF type, reference data for validation, preprocessing method, and the method for calculation of relative wind direction. It is expected that this study contributes to the potential users of SAR images who retrieve wind speeds from SAR data at the coastal region around the Korean Peninsula.

This study was conduct to investigate the effect of mixed seed sowing and flour blending on the uniformity of flour quality of Korean domestic wheat. Two wheat varieties (Keumkang and Baegjoong) were selected for sowing mixed seeds, and their growth characteristics and flour quality were analyzed. Quality of flour blending with the same varieties was also evaluated. The ratios for mixed seed sowing and flour blending were from 0 to 100% with a 10% increase of interval for each treatment. On increasing the portion of Baegjoong in mixed seed sowing, the heading time was a little delayed, however, yield increased. The results of the flour quality showed lower damaged starch content and sodium carbonate SRC (solvent retention capacity) value for Keumkang than for Baegjoong. Protein quantity by protein content and quality by SDSS (Sodium Dodecyle Sulfate-Sedimentation) volume, lactic acid SRC, and mixograph pattern of Keumkang were superior to those of Baegjoong. Compared with mixed seed sowing, overall quality characteristics of flours with different ratios showed predictable and proportional change by flour blending. This demonstrated the successful application of flour blending, compared with mixed seed sowing, for improving the uniformity of flour quality.
