The aim of the study is to investigate the effect of the benefit of soft waxing, hard waxing, and sugaring waxing on intention to reuse in Korean adults, and to provide useful information to people who are new to waxing. As a research method, from May 1, 2019 to August 30 (17 weeks), we surveyed 422 subjects between 10 and 40 years old who lived in Busan and Yeongnam area and experienced waxing. In statistical analysis, Cronbach's alpha was calculated for reliability test, and Chi-squared test, independent t-test, correlation analysis and linear regression analysis were used. Multiple responses were analyzed using multiple response test. In the result of the effect of waxing benefit on intention to reuse, there was a significant positive correlation of waxing seeking score by body part, total waxing benefit score(r=0.389, p<0.001), and total score of intention to reuse (r=0.214, p>0.001) with intention to reuse. There was also a significant positive correlation between waxing benefit by body part and intention to reuse, except arms and legs. In the result of the effect of waxing benefit on intention to reuse, face waxing (β=0.106, p<0.001), Brazilian waxing (β=0.221, p<0.001) and total waxing benefit score (β=0.321, p<0.001) had a significant effect on intention to reuse. In the present study, awareness of sugaring waxing was low but favor and intention to reuse were strong, and the subjects sought sugaring waxing for sensitive body parts. Thus, would provide useful information for consumers new to waxing, and also basic information for studies on waxing.
Yeon Sang-Ho's Animation occupies an exceptional place in Korean Animation, being categorized as the kind of realism representing the pitiable actuality rather than the liberal and creative imagination. His animation appreciated as 'stories much more real than the reality' mainly depicts the world of 'the others' who resides on the periphery of the society in a rough and straightforward way. Yeon Sang-Ho's Animation represents the emotions and desire of characters as well as the heartless real world refusing the fantasy, through which it reflects the portraits of people living in post-capitalistic era seen from the microscopic view. This article investigates the textual characteristics, defining his animation as the Brutal history of 'The Others'. Two conditions which constitute the actual world in his works are the absurd social system and the characters who are afflicted with the trauma, belonging to the lower classes. Therefore, the landscape of real life which contains vicious victim, corrupted monster and being as 'homo sacer' looks like a painting of hell. Yeon Sang-Ho's Animation summons the shadow of ourselves which has been negated or neglected through the figure of 'the others' produced in post-capitalistic era and exposes our bare face and the uncomfortable truth by displaying the affected area of out society plainly. Furthermore, his works demonstrate the possibility of Korean animation as a representational language of facing the reality and searching for the truth.
The transfer slab system is a structural system that transfers the loads from the upper shear wall structure to the lower columns. This is a costly system due to a very thick slab, and the relatively high cost can be mitigated by introducing voids in the slab. However, this system of flat plate containing voids is vulnerable to brittle failure caused by punching shear in vicinity of slab-column connection. Thus, the punching shear capacity of the void system is very important. However, the current code doesn't provide a clear design provision for the strength of slabs with a void section. In this study, experimental study was conducted to investigate the punching shear strength of the void slab system. The shear strength of the specimens was predicted by current code and previous researches. In result, the punching shear strength of the void system is determined as the least value calculated at critical section located a distance d/2 from the face of the column and the center of the void section using the effective area at critical section.

Carbon nanotubes (CNTs) belong to an ideal material for field emitters because of their superior electrical, mechanical, and chemical properties together with unique geometric features. Several applications of CNTs to field emitters have been demonstrated in electron emission devices such as field emission display (FED), backlight unit (BLU), X-ray source, etc. In this study, we fabricated a CNT cathode by using filtration processes. First, an aqueous CNT solution was prepared by ultrasonically dispersing purified single-walled CNTs (SWCNTs) in deionized water with sodium dodecyl sulfate (SDS). The aqueous CNT solution in a milliliter or even several tens of micro-litters was filtered by an alumina membrane through the vacuum filtration, and an ultra-thin CNT film was formed onto the alumina membrane. Thereafter, the alumina membrane was solvated by acetone, and the floating CNT film was easily transferred to indium-tin-oxide (ITO) glass substrate in an area defined as 1 cm with a film mask. The CNT film was subjected to an activation process with an adhesive roller, erecting the CNTs up to serve as electron emitters. In order to measure their luminance characteristics, an ITO-coated glass substrate having phosphor was employed as an anode plate. Our field emitter array (FEA) was fairly transparent unlike conventional FEAs, which enabled light to emit not only through the anode frontside but also through the cathode backside, where luminace on the cathode backside was higher than that on the anode frontside. Futhermore, we added a reflecting metal layer to cathode or anode side to enhance the luminance of light passing through the other side. In one case, the metal layer was formed onto the bottom face of the cathode substrate and reflected the light back so that light passed only through the anode substrate. In the other case, the reflecting layer coated on the anode substrate made all light go only through the cathode substrate. Among the two cases, the latter showed higher luminance than the former. This study will discuss the morphologies and field emission characteristics of CNT emitters according to the experimental parameters in fabricating the lamps emitting light on the both sides or only on the either side.

In Oriental medicine, the status of a tongue is the important indicator to diagnose the condition of one's health like the physiological and the clinicopathological changes of internal organs in a body. A tongue diagnosis is not only convenient but also non-invasive, and therefore widely used in Oriental medicine. However, the tongue diagnosis is affected by examination circumstances like a light source, patient's posture, and doctor's condition a lot. To develop an automatic tongue diagnosis system for an objective and standardized diagnosis, segmenting a tongue region from a facial image captured and classifying tongue coating are inevitable but difficult since the colors of a tongue, lips, and skin in a mouth are similar. The proposed method includes preprocessing, over-segmenting, detecting the edge with a local minimum over a shading area from the structure of a tongue, correcting local minima or detecting the edge with the greatest color difference, selecting one edge to correspond to a tongue shape, and smoothing edges, where preprocessing consists of down-sampling to reduce computation time, histogram equalization, and edge enhancement, which produces the region of a segmented tongue. Finally, the systematic procedure separated only a tongue region from a face image with a tongue, which was obtained from a digital tongue diagnosis system. Oriental medical doctors' evaluation for the results illustrated that the segmented region excluding a non-tongue region provides important information for the accurate diagnosis. The proposed method can be used for an objective and standardized diagnosis and for an u-Healthcare system.

The uniaxial compressive strength of rock mass is known as the major factor in the assessment of drillability and the optimum excavation design in full-face tunnel excavation by TBM. Referring to worldwide cases, TBM has been applied mostly to the rock mass within the strength range of 80~250 MPa. Recently, a water way tunnel has been constructed as a part of Milyang dam project by TBM within the rock masses where the rock type is mainly granite with some granophyre, hornfels and andesite. Their uniaxial compressive strengths in extended area are estimated higher than 260 MPa. In this paper, the relation between the penetration rate and the rock mass properties is analyzed and TBM application to the very hard rocks is discussed. As a result that three suggestions to predict the TBM net penetration rate are analyzed, NTH method seems a better approach than other methods in the extremely hard rocks. NTH prediction matches with the results of actual values with the variations of 2~20%. Hardness measurement by Schmidt hammer and RMR estimation are carried out along the L = 5.3 km entire TBM tunnel alignment. The net penetration rate measured monthly is shown to be reciprocally proportional to Schmidt rebound hardness and RMR where coefficients of correlation, $R^2$are 0.705 and 0.777 respectively. As a result, they are good quantitative indices for the prediction of TBM net penetration rate in the extremely hard rocks. Magnitude of in-situ stress has a certain effect on TBM performance, and it is required to measure the in-situ stresses in TBM excavation design.
The ultimate goal of the local government is the owner of the residents welfare of the community. Welfare of the residents will start from the protection of life and property of the inhabitants. Much of this protective activity is a function of the police. Therefore, to be a municipal & local police that is based on the autonomy of the local conceptual prerequisites for the welfare of the population. Municipal & local police activities are activities for the local community rooted in the community that the police and to rejoin the community, municipal & local police activities taking place in the center of the area to solve the problem, but to reduce the fear of crime and disorder, crime as an expression of the efforts of the local residence themselves to improve the overall quality of life of the community as a partner recognition local residents. Municipal & local police in this case be introduced across the board in the central and local governments is careful review of the various alternatives been prepared on analysis is crucial to reduce the trial and error by providing the best alternative. priority should be to figure out exactly what the reason to introduce a municipal police. in other words, the introduction of the municipal & local police in the central and local governments, state police and municipal & local police, the ruling party and the opposition, regional self-government initiative unseen conflict between organizations and local governments are not welcomed by local residence in local time truly 'safe' and will have to face that the 'improve quality of life'.

This study evaluated anti-wrinkle effect using toner and lotion containing ginsenoside Rg3 enriched black ginseng in oriental medicine like Liriope platy phyllla, Inonotus obliquus, Glycyrrhiza glabra and nourishing of the blood and energy(Atractylodes japonica, Poria cocos Wolf, Angelica gigas, Rehmanniae Radix Preparata, Cnidii Rhizoma, Paeonia lactiflora). 6 female adults on average at the age of 42.5 applied lotion after toner under the normal conditions of use on the face including crow's feed area, twice a day (in the morning and evening) for 4weeks. After 4 weeks, the replica of eye wrinkle was made and analyzed the image. The result was decreased in R1($3.15{\pm}0.35$ to $2.28{\pm}0.22$), R2($2.99{\pm}0.37$ to $2.13{\pm}0.21$), R3($2.09{\pm}0.31$ to $1.56{\pm}0.18$), R4($0.37{\pm}0.05$ to $0.29{\pm}0.03$), and R5($0.89{\pm}0.1$ to $0.75{\pm}0.06$)(P<0.05). Therefore, oriental medicine cosmetics containing black ginseng may play a role anti-wrinkle.
Introduction: Distraction osteogenesis is widely used as for bone lengthening in patients with maxillofacial deformity and alveolar bone atrophy. One of the major problems in distraction osteogenesis is long consolidation period for 2-3 months, in which the devices have to be fixed on the bone to prevent relapse. It results in scar formation on the face, disturbance of mastication and speech. This study was performed to evaluate the stimulating effect of pulsed electromagnetic field on the early bone consolidation in distraction osteogenesis. Materials and methods: Total 10 rabbit were used (5 for control group, 5 for experimental group). A vertical osteotomy in the mandibular body was performed and the distraction device was fixed. After 5 days distraction was done 1mm per a day for 7 days. A pulsed electromagnetic field (38 Gauss, 60 Hz) was applied for 8 hours per day and it continued for 5 days immediately after distraction in the experimental group. Both groups were sacrificed after 2 weeks. Histological specimens with H&E and Masson Trichrome staining were made and histomorphometrically analysed with image analyser. Results: The device for distraction osteogenesis was displaced in one animal for each group, therefore, only four animals in both groups were evaluated. In both groups, a new bone formation was observed in the distracted area after 2 weeks. The bone formation was enhanced in the experimental groups ($31.76{\pm}8.68%$) compared with control group ($9.94{\pm}3.23%$), its difference was statistically significant (p<0.001). Conclusion: This study suggests that electrical stimulation with electromagnectic field may be effective in the early bone formation after distraction osteogenesis. Further studies with large number of animals are needed before clinical application.
The cut-slope of a large-sectional tunnel portal is recognized as a potential area of weakness due to unstable stress distribution and possible permanent displacement. This paper presents a case study of a slope failure and remediation for a large-scale cut-slope at a tunnel portal. Extensive rock-slope brittle failure occurred along discontinuities in the rock mass after 46 mm of rainfall, which caused instability of the upper part of the cut-slope. Based on a geological survey and face mapping, the reason for failure is believed to be the presence of thin clay fill in discontinuities in the weathered rock mass and consequent saturationinduced joint weakening. The granite-gneiss rock mass has a high content of alkali-feldspar, indicating a vulnerability to weathering. Immediately before the slope failure, a sharp increase in displacement rate was indicated by settlement-time histories, and this observation can contribute to the safety management criteria for slope stability. In this case study, emergency remediation was performed to prevent further hazard and to facilitate reconstruction, and counterweight fill and concrete filling of voids were successfully applied. For ultimate remediation, the grid anchor-blocks were used for slope stabilization, and additional rock bolts and grouting were applied inside the tunnel. Limit-equilibrium slope stability analysis and analyses of strereographic projections confirmed the instability of the original slope and the effectiveness of reinforcing methods. After the application of reinforcing measures, instrumental monitoring indicated that the slope and the tunnel remained stable. This case study is expected to serve as a valuable reference for similar engineering cases of large-sectional slope stability.
