  • Purpose: We review published research on temporomandibular joint (TMJ) total replacement that compares costochondral graft and customized total joint reconstruction (especially TMJ concepts), focusing on effectiveness. Methods: We searched PubMed databases, including prospective, retrospective, case-control or longitudinal studies and significant statistical analysis. In data analysis, we divided outcomes into 'Acceptable' or 'Non-acceptable'. Results: There were seven articles found dealing with costochondral graft and 180 patients. The majority of patients had satisfactory treatment outcomes (n=109, 61%). There were six articles including 275 patients using the alloplastic material TMJ concepts. Almost all patients had satisfactory treatment outcomes (n=261, 95%). Conclusion: Comparing customized total joint reconstruction with costochondral graft, use of TMJ concepts resulted in increased quality of life and fewer complications. In conclusion, we judged that alloplastic material such as TMJ concepts is more effective device in total joint replacement than costochondral graft.

  • The objective of this study was to evaluate the effect of the amount of water and several kinds of sweeteners on the texture such as grain appearance, softness, moistness, chewiness, cohesiveness, gumminess and elasticity of Backsulgi when one manufactures Backsulgi. Different amount of water of 30 ml, 60 ml and 90 ml/350 g of powdered rice and such sweetners as sugar, honey and syrup were employed for the experimental treatments. The evaluation of these results were dependent on statistical data of some scores that were obtained through sensory evaluation and Instron Universal Testing Machine. According to this sensory evaluation, the texture of Backsulgi was more affected by the change of water quantity than that of sweeteners. Judging from the results of Instron Universal Testing Machine, it was found that there were no statistically significant differences in each treatment of the cohesiveness, elasticity and hardness of Backsulgi, but some statistically significant difference was observed in each treatment of the gumminess and chewiness of Backsulgi(p<0.05).

  • The purpose of this study was to analyze the factors affecting the unmet dental needs of Koreans. In relation to the subjects and methodology for this study, the data from the 5th national health nutrition survey which had been conducted between 2010 and 2012 were analyzed by using the PASW statistics 18.0 (SPSS Inc., Chicago, IL, USA), a statistical program, through the frequency analysis of complex samples, cross analysis of complex samples, and logistics regression analysis of complex samples. The results of analysis showed that the rate of unmet dental needs stood at 35.3% of all subjects. Moreover, to determine the factors related to the unmet dental needs, the logistics regression analysis of complex samples was conducted. The results of analysis showed that the demographic and socio-economic factors and oral health condition factors had relationship with unmet dental needs. It is necessary to consider all the objective dental treatments that reflect specific dental diagnosis from a comprehensive standpoint.

  • Nonparametric procedures in a randomized block design was proposed by Friedman (1937) as a general alternative as well as suggested as a test for ordered alternatives by Page (1963). These methods are used for the rank of treatments in each block. In this paper, we proposed nonparametric procedures using aligned method proposed by Hodges and Lehmann (1962) to reduce among block information and based on placement suggested by Kim (1999) in a randomized block design. We also perform a Monte Carlo study to compare the empirical powers of the proposed procedures and established method.

  • Measurements of linear motion accuracy for one axis of NC lathe have achieved with laser interferometer system, but measurement of plane motion accuracy for two axes on zx-plane of NC lathe have not achieved with the above system. Therefore in this study, measuring unit system is organized using two optical linear scales in order to acquire error. data during of plane motion of ATC(Automatic Tool Change.) of NC lathe by reading zx-plane coordinates. Two optical linear scales of measuring unit are fixed on zx-plane of NC lathe, and moving part of the scales are fixed to the ATC and then error motion data of z, x-coordinates of the ATC are received from the scales through the PC counter card inserted in computer at constant time intervals using tick pulses coming out from computer. And then, error motion data files acquired from measuring are saved in computer memory and the aspect of plane motion are modeled to plots, and range of the error data, means. average deviations, and standard deviations etc. are calculated by means of statistical treatments using computer programs.

  • The experiment was conducted to determine the optimum stocking density for Korean Native Chicken. The experiment was carried out with 810 Korean Native Chickens for 16weeks from April 22. 1987 to August 11. 1987. The chickens were housed in pens with varying stocking densities; T1(20 birds per 3.3$m^2$), T2(30 birds per 3.3$m^2$), T3(40 birds per 3.3$m^2$), T4(50 birds per 3.3$m^2$), T5(60 birds per 3.3$m^2$) and T6(70 birds per 3.3$m^2$). Each treatment contained three replicates. At the end of the trial, the average body weight of T1 was significantly heavier than that of T5 (P<0.05), but there were no statistical differences among the treatments in fed intake. The feed conversion of T3 was improved significantly in comparison with that of T5(P<0.05), and the viability of T1 showed a significantly difference with that of T5, T1 showed the highest production number, whereas T5 the lowest one.

  • The effect of gamma-irradiation on the hydrolytic enzyme activities of some Koran soybean-based fermented foods was studied. Doenjang (soybean paste), kanjang (soy sauce), kochujang (red pepper paste), chungkukjang and meju were prepared and irradiated at 0, 5, 10 and 20 kGy. Then activities of protease, amylase, lipase and fibrinolytic enzyme were determined. Hydrolytic enzyme activities of meju, chungkukjang and doenjang were relatively higher than those of kanjang and kochujang. Amylase, protease and lipase activities were not affected by 10 kGy and were slightly (about 10%) inactivated by 20 kGy of gamma irradiation, with no statistical significance. Fibrinolytic enzyme was stable in all treatments.

  • Distal humerus fractures (DHFs) are challenging to treat due to the locally complex osseous and soft tissue anatomy. Adequate exposure of the articular surface of the distal humerus is crucial when performing an anatomical reconstruction of the elbow. Even though "triceps-on" approaches are gaining popularity, one of the most commonly used surgical treatments for DHF is olecranon osteotomy. The incidence of complications related to this approach is unclear. This review was performed to assess the type and frequency of complications that occur with the olecranon osteotomy approach in the treatment of DHF. A literature search was conducted in the PubMed/Medline, Embase, and Cochrane Library digital databases up to February 2020. Only English articles describing complications of olecranon osteotomy in the treatment of DHF were included. Data on patient and surgical characteristics and complications were extracted. Statistical analysis was performed using SPSS. A total of 41 articles describing 1,700 osteotomies were included, and a total of 447 complications were reported. Of these 447 complications, wound infections occurred in 4.2% of osteotomies, of which 1.4% were deep infections and 2.8% were superficial. Problems related with union occurred in 3.7% of osteotomies, 2% of which represented non-union and 1.7% delayed union. The high risk of complications in olecranon osteotomy must be considered in the decision to perform this procedure in the treatment of DHF.
