The purpose of this study was to review the contents of the family ethics of Cho-Seon Dynasty in $\boxdr$Sa So Jeol$\boxul$written by Deok Moo Lee in 1775. The major findings on the family ethics of Cho-Seon Dynasty can be summarized as follows: 1) The marital relationship must keep to be equal, although they have different characters in the personality and different roles in the family. And husband/wife has to respect each other, to try to do for the marital harmony, and to treat nicely to his/her spouse. 2) In the parents-children relationships, children shoed respect and support their parents sincerely while parents’lifetime and perform an ancestral sacrifice wholeheartedly after parents’death. And parents haute the right and duty to educate their children. They have to teach their son to attend to his studies with diligence and teach their daughter to make efforts for the family and kin relationships. If parents or children are in fault, children shoed request to rethink the parents’fault to their parents earnestly and parents must also admonish their children with love. 3) In the sibling relationships, they have to show the fraternity each other. And the younger has to respect especially to elder brother.

Cannibalism plays important roles at the levels of both individual and population. To enhance overall rate of successful survival and reproduction, salamander larvae may have evolved to consume both conspecifics and heterospecifics. Consuming conspecifics could result in decreased inclusive fitness possibly by killing relatives. In several salamander species, discrimination of salamander larval siblings from non-siblings and heterospecifics to avoid such a risk has been reported. To determine whether the Korean salamander larvae consume non-siblings more often than siblings and to analyze prey preferences of the salamander larvae in several different experimental conditions, a series of foraging experiments was conducted in the laboratory. We found that 1) large cannibal larvae preyed on small sibling more often than small non-sibling in a mixed group of sibling and non-sibling, 2) cannibal larvae prefered to consume live, weak, and small larvae to dead, healthy, and large larvae, and 3) cannibal larvae consumed heterospecific tadpoles more often than conspecific nonsibling larvae in a mixed group. In addition, the larval density was positively correlated with the occurrence of spacing behavior, one of the agonistic predator behaviors among salamander larvae.

This study was performed to investigate the effect of activated charcoal on wound healing in an experimentally induced skin wound model. Full-thickness, skin defects ($2 cm{\times}2 cm$) were made in two different areas on the back of eight New Zealand white rabbits. Eight of 16 wounds were treated with gauze-gauze-impregnated activated charocal granules, and another eight wounds were treated with gauze-soaked saline. Wound areas were measured every other day for 2 weeks after the wound-ing. Statistical analysis was performed with the student t-test. The mean percentage of wound con- traction on the 14th day in the activated charcoal-treaded group and in the saline treated group were 93.5% and 81_7%, respectively. The mean value of tensile, strength ell the 21s1 day after wounding was,42.70{\pm}0.8 kg/5cm^2$,/TEX> in the activated charcoal-treated group and $1.75 {\pm} 0.5 kg/5 cm^2$ in the saline treated group. Significantly reduced wound area (p<0.05) and high tensile strength value (P<0.O5) were observed in activated charcoal-treated group compared with those in the saline treated group. In summary activated charcoa1 significantly reduced the wound area an increased tensile strength in the rabbit 7kin wound model. These results suggest that application of activated charcoal in skill wounds will promote wound healing.

Cardiac function is evaluated quantitatively using angiographic images via the analysis of the shape change or the heart wall boundaries. To kin with, boundary defection or ESLV(End Systolic Lert Ventricular) and EDLV(End Diastolic Left Ventricular) is essential for the quantitative analysis of cardiac function. The boundary detection methods proposed in the past were almost semi-automatic. Intervention by a knowledgeable human operator was still required Of con, manual tracing of the boundaries is currently used for subsequent analysis and diagnosis. This method would not cut excessive time, labor, and subjectivity associated with manual intervention by a human operator. EDLV images have noncontiguous and ambiguous edge signal on some boundary regions. In this paper, we propose a new method for automated detection of boundaries in noncontiguous and ambiguous EDLV images. The boundary detection scheme which based on a priori knowledge information is divided into two steps. The first step is to detect the candidate edge points of EDLV using ESLV boundaries. The second step is to correct detected boundaries of EDLV using the LV shape. We developed the algorithm of modifying EDLV boundaries defined adaptive modifier. We experimented the method proposed in this paper and compared our proposed method with the manual method in detecting boundaries of EDLV. In the areas within estimated boundaries of EDLV, the percentage of error was about 1.4%. We verified the useflilness and obtained the satisfying results througll the experiments of the proposed method.

The purpose of this study was to determine the effect of muscle contraction torque and muscle fatigue by low-frequency PC. In this article, We would like to experiment on electrical stimulation, determine optimal forms of stimulation setting. We used normal fourteen subjects(seven women, seven men) without neuromuscular disease and all subjects participated in the 3 session. Torque was measured using a computerized Kin-Com dynamometer for MVIC, MIC, Fatigue tests. The following results were obtained; 1. Torque of man were significantly higher than women in the MIC test(p<.05). 2. Torque of women, man were significantly decreased in the Fatigue test(p<.001). Between woman and man groups were significant difference(p<.05). These results lead us to the conclusion that muscle fatigue was influenced by PC, fatigue of women was higher than man. Therefore, A further studies concerning the electrical stimulation should consider differences between sexes in response to treatment and could enhance the development of the most effective treatment regimens.

A new flexible TFT backplane structure with improved mechanical reliability is proposed. Amorphous indium-gallium-zinc-oxide (a-IGZO) thin film transistors based on this structure have been fabricated on a polyimide substrate, and the resultant mechanical durability has been evaluated in a cyclic bending test. The panel can withstand 10,000 bending cycles at a bending radius of 5 mm without any noticeable TFT degradation. After 10K bending cycles, the change of threshold voltage, mobility, sub-threshold slope, and gate leakage current were only -0.22V, -0.13$cm^2$/V-s, -0.05V/decade, and $-3.05{\times}10^{-13}A$, respectively.

This paper suggests the sensor-less speed control of PMSM (Permanent Magnet Synchronous Motor) without the position sensor of oil-free air compressor. It estimated d and q axis back electro motive force using Back-EMF (Electro motive Force) observer to control sensor-less speed of PMSM. Also it used the method that tracks the information of rotor position and speed using PLL (Phase Locked Loop) based on estimated d and q axis Back-EMF. The sensor-less speed control of PMSM for oil air compressor application is carried out with the introduced rotor position and speed tracking method. In this paper, the experimental characterization of the sensor-less drive is provided to verify the accuracy of the estimated position and the performance of sensor-less control is analyzed by results obtained from the experiment. Moreover, the potential of PMSM sensor-less drive in industrial application such as compressor drive is also examined.
