This study surveyed 506 medical students on their perception of life concept using an open-ended questionnaire. A constant comparative analysis of participants' written responses was conducted. The results revealed 3 main types and several sub-types of life concept. The main types included: humanities & sociology type, scientific type, and humanities sociology & science mixed type. The humanities & sociology type had 6 sub-types: religious values, ethical values, limited time, social characteristics, consciousness spirit soul, and mixed type. The scientific type had 4 sub-types as follows: respiration & metabolism, genetic & reproduction, homeostasis & emergent property, and mixed type. The most prevalent type was the perception that life concept, ethical values in humanities & sociology type. The understanding of the concept of life is essential to medical students' learning and improvement of professional competence. These results may suggest a meaningful direction for medical education regarding the concept of life.

This article focuses on providing remedial solutions for COVID disease through the data collection process. Recently, In India, sudden human losses are happening due to the spread of infectious viruses. All people are not able to differentiate the number of affected people and their locations. Therefore, the proposed method integrates robotic technology for monitoring the health condition of different people. If any individual is affected by infectious disease, then data will be collected and within a short span of time, it will be reported to the control center. Once, the information is collected, then all individuals can access the same using an application platform. The application platform will be developed based on certain parametric values, where the location of each individual will be retained. For precise application development, the parametric values related to the identification process such as sub-interval points and intensity of detection should be established. Therefore, to check the effectiveness of the proposed robotic technology, an online monitoring system is employed where the output is realized using MATLAB. From simulated values, it is observed that the proposed method outperforms the existing method in terms of data quality with an observed percentage of 82.

Purpose: The purpose of this study was to explore the structure and characteristics of male college nursing students' personality-based career attitudes. Method: The Q-methodology was used to identify factors in male nursing students' personality-based career attitudes. A Q sample was collected from literature reviews (Kim & Kim, 2005). The subjects consisted of 30 male nursing students. Result: The results of the study show that male nursing students can be categorized into four types. The five factors extracted all had eigen values greater than 1.0 and explained approximately 50.84% of the variation in responses (32.62, 7.59, 5.70 and 4.93% respectively). The categories were labeled 'Repair intention style', 'Belief intention style', 'Stability intention style', and 'Self-regulation intention style'. Conclusion: Through a process that analyzes subjective structure, male nursing students' personality based career attitudes create occupational consciousness, professional accomplishment and professional ethics as a nursing profession. Content of curriculum and development of a reasonable and realistic course consultation program should be done.

In this study, lotus root(Nelumbo nucifera G.) and omija(Schizandrae fructus), which have been used in oriental medicine and folks remedy, were examined to apply to functional foods. We prepared yanggaeng with lotus root, sugar, oligosaccharide, agar, omija extract solution and analyzed the nutritional composition(moisture, protein, fat, ash, crude fiber, carbohydrate, free sugar and minerals). Also we investigated texture profile and evaluated sensory characteristics of developed yanggaengs and 8 commercial ones. Potassium and crude fiber contents of yanggaeng with lotus root were higher than the commercial yanggaengs. Cohesiveness, springiness and gumminess of lotus root yanggaeng were the same levels of commercial yanggaengs. Sensory evaluation with the ones, showed that the lotus yanggaeng was more desirable than the commercial ones. Yanggaeng with lotus had good scores in texture profile and sensory evaluation compared with commercial yanggaengs. These results demonstrated that lotus root hadsufficient values to use a foodstuff for yanggaeng.

The analysis of Geotechnical stability problems by the limit equilibrium method involve assuming the shape of the failure and then investigating many surfaces of the shape to identify the one on which failure seems most likely to occur. These arbitrary assumptions most frequently concern to the locations or directions of side force on slice and the overall factor of safety is considered identical to the local factor of safety. In this paper, let the factor of safety of a slope at wedge block stage differently, when an upper part of the potential sliding mass has a simple active stress field and the lower part of the passive stress field and overall factor of safety is obtained by the average of local factor and computer program based on the modified wedge Method is proposed for this thesis. The new algorithm based on tile modified new method is made for estimating the safety factor of Earth Dam. Compared with conventional method for many cases tile average values of the factor of safety determined by the modified new method are very nearly the same. For all of the cases studied the difference was found 0.03. Finally this new method is thought to be very useful in slope stability analysis.

The traffic congestion of Seoul city has been one of the most serious problems to be settled since the advent of 1970s. As a means to mitigate traffic mess, the authority concerned launched the construction of subway line 3 and 4 in 1980. The two Subway lines slated for completion by 1985 cross each other and run north-south direction, passing through the metropolitan area of Seoul city fraught with high-rise edifices and large-scale shopping centers, and, in order to reduce blasting vibration, NATM was executed for a distance of 10 Km, instead of ASSM previously employed when subway line 1 and 2 were constructed. Tunnel blastings were implemented, preceded by classifying the rocks at construction area into five categories, namely, hard rock, semi-hard rock, weak rock weathered rock and silt and by calculating their respective specific charges through standard test blastings, by employing the pre-splitting and smooth blasting with drilling patterns of burn cut type, so as not to cause damages to surface structures. Most of explosives used were the slurry of low specific gravity and low velocity, and the firings executed by the use of milli-second detonators. Empiric formula were also formulated to check blasting vibrations, based on the vibration allowable values of West Germany standard, for the application to vulnerable construction zones. Should the two lines be placed for public service in 1985, about 40% of the total traffic population of Seoul city amounting to 15 million as of 1984 is estimated to be carried by subway with no difficulties.

The aim of this study was to develop antitoxic compound for cadmium-induced cytotoxic Vero cells. These cells were divided into five groups; control group (medium only), cadmium group (cadmium only), and two experimental groups. SRB (sulphorodamine B) assay was performed to evaluate the cytotoxicity of cell organelles. After cadmium was treated on Vero cells, we determined IC50 values to examine the detoxification effects of Houttuynia cordata methanol extract and quercetin under cadmium-induced cytotoxicity. Furthermore, morphological changes were observed by the light microscope. In Vero cells, methanol extract of Houttuynia cordata, and quercetin showed inhibitory effects on cadmium-induced cytotoxicity and these detoxification effects were increased in a concentration-dependent manner. These results suggest that methanol extract and quercetin from Houttuynia cordata retain a potential antitoxic activity.

This study was performed to investigate the antioxidant activity of extracts of black Panax ginseng (BGE) and its crude saponin (BGECS). The antioxidant activities of BGE and BGECS were evaluated for free radical scavenging activity against stable free radical (1,1-diphenyl-2-picrylhydrazyl) DPPH, nitrite, hydrogen peroxide and superoxide. In addition, the antioxidant activity of BGE and BGECS against peroxyl radicals, hydroxyl radicals and peroxynitrites were determined by the total oxy-radical scavenging capacity (TOSC) assay. As a result, BGE and BGECS were found to have a strong inhibitory activity with >90% against the DPPH radical at $1000{\mu}g/m{\ell}$ concentrations. Also, BGE and BGECS exhibited strong inhibitory activity with >80% against hydrogen peroxide at lower concentration ($125{\mu}g/m{\ell}$). Moreover, specific TOSC values (405 and 473 TOSC/mM) of BGE and BGECS against peroxynitrites were higher than GSH (347 TOSC/mM) used a positive control. These results suggest that BGE and BGECS could be useful to develop functional foods against disease related oxidative stress.

The Supreme Court made a decision that the doctor cannot be punished for not taking a blood transfusion to the patient, depending on the patient's will to refuse the blood transfusion on June 24, 2014. The reason is that, in a special situation of conflict between the right of patients to self-determination and the duty of care, and when it was impossible to compare whether which has the superior value, if the doctor made a medical practice to respect either of those two values according to the professional sense, he cannot be punished. In principle, the doctor should make medical practices according to the patient's will. However, if the patient's life was at stake, I think, the doctor is obliged to try his best to save the life of patient. Yet to entrust the patient's life to the doctors professional sense, is to give up the obligation of the country to protect lives. In this regard, I think that the Supreme Court Decision should be reviewed, and that an ongoing research is needed.
