A new method for synthesizing the tetrazole derivatives from secondary amines through cyanation/tetrazolation has been developed. Trichloroacetonitrile is used as the cyano source to synthesize N-nitrile instead of highly toxic and expensive cyanogen bromide. In this protocol, the reaction of secondary amines with various substituents proceed smoothly, and the desired tetrazole derivatives are obtained directly in fair to high yields without isolation of intermediate cyanamides.

Certified E-mail 프로토콜은 공정한 교환(fair exchange)을 보장하기 위하여 신뢰된 제 3자 (Trusted Third Party, TTP)톨 사용한다. 그러므로, Certified E-mail을 사용하는 유저들은 원격지의 TTP를 완전히 신뢰(fully-trust)해야 한다. 만약 TTP가 훼손되거나 유저와 공모하여 악위적인 행동을 한다면 Certified E-mail 프로토콜의 공정성(fairness)은 붕괴된다. 본 논문에서는 Threshold secret sharing을 사용하여 TTP의 신뢰성을 분산시킨 강건한 Certified E-mail 프로토콜을 제안한다. 분산된 TTP(Distributed TTP, DTTP)를 사용하므로써 유저가 공모하는 악위적인(malicious) TTP에 대한 공격을 막을 수 있으며 어느 한 DTTP가 훼손되더라도 전체 프로토콜에 영향을 주지 못한다.

The article is devoted to the problems and prospects of integration of informational technologies in the administration of justice as a necessary component of the development of the informational society in Ukraine. In general, informational technologies make it possible to create new forms of organization and interaction of bodies of public authorities with society, to introduce innovative solutions for legal regulation and organization of public relations. More and more services for citizens are moving to electronic format. Judicial reform is aimed at ensuring more comfortable and convenient interaction with the courts. The need for the usage of informational technology in the proceedings is preconditioned by the global informatization of modern society, the development of new forms of interaction in the civil sphere with the usage of electronic means of communication: the global Internet, mobile, and satellite communication systems and more. "Electronic justice" involves the use of information and communication technologies in the implementation of procedural law.

Protein-enriched dairy powder is widely consumed to promote muscle synthesis. Recently, in Korea, elderly people have also begun consuming protein powder products to prevent muscle loss. However, these protein-enriched powders have poor flowability and hydration properties because of the fine particles of spray-dried milk protein powder. Therefore, in this study, the fluidized bed agglomeration process was used to solve these problems. The rheological and physical properties of milk protein isolate (MPI)/skim milk powder (SMP) mixtures were effectively improved via fluidized bed agglomeration. The particle size of the MPI/SMP mixtures significantly increased from 35.7-58 ㎛ to 118-136 ㎛, the flowability level improved from fair (21.4-26.3) to good (15.7-16.3), and the cohesiveness level changed from intermediate (1.27-1.36) to low (1.18-1.19) after fluidized bed agglomeration. In addition, the wetting time of the agglomerated MPI/SMP mixtures was effectively reduced to 4.67-58.3 s by fluidized bed agglomeration. These findings may be useful for manufacturing protein-enriched dairy powders with good instant properties.

A three-year-old female spayed Lurcher was referred for the treatment of a highly comminuted distal tibial articular fracture. Resection of the area of comminution with a transverse osteotomy of the tibial diaphysis and talar ridges was performed, followed by modified pantarsal arthrodesis and a calcaneotibial screw. The treatment resulted in 7 cm of tibial shortening, equating to a 28% reduction in the total tibial length. Radiographic union of the arthrodesis was successful. Fair use of the pelvic limb was documented long-term. Combined acute limb shortening and modified pantarsal arthrodesis resulted in an acceptable outcome and could be considered in cases of highly comminuted distal tibial fractures.

This study addresses the prevalent issue of meat species authentication and adulteration through a chemometrics-based approach, crucial for upholding public health and ensuring a fair marketplace. Volatile compounds were extracted and analyzed using headspace-solid-phase-microextraction-gas chromatography-mass spectrometry. Adulterated meat samples were effectively identified through principal component analysis (PCA) and partial least square-discriminant analysis (PLS-DA). Through variable importance in projection scores and a Random Forest test, 11 key compounds, including nonanal, octanal, hexadecanal, benzaldehyde, 1-octanol, hexanoic acid, heptanoic acid, octanoic acid, and 2-acetylpyrrole for beef, and hexanal and 1-octen-3-ol for pork, were robustly identified as biomarkers. These compounds exhibited a discernible trend in adulterated samples based on adulteration ratios, evident in a heatmap. Notably, lipid degradation compounds strongly influenced meat discrimination. PCA and PLS-DA yielded significant sample separation, with the first two components capturing 80% and 72.1% of total variance, respectively. This technique could be a reliable method for detecting meat adulteration in cooked meat.

This study aims to understand the relationships between antecedents (recognition, empowerment, fair rewards, procedural justice(PJ), perceived organizational support(POS) and consequence(turnover intention(TI) of job engagement in a super deluxe hotel's F&B departments. Based on a total of 402 useful samples obtained for the empirical research, this study reviewed reliability and fitness of the research model and verified total 6 hypotheses with through the use of the AMOS statistical program. The hypothesized relationships in the model were tested simultaneously by using a structural equation model(SEM). The proposed model provided an adequate fit to the data, ${\chi}^2=668.894$(p<.001), df=373, CMIN/DF=1.794, GFI=.901, AGFI=.877, NFI=.928, CFI=.967, RMSEA=.044. The model's fit, as indicated by these indexes, was deemed satisfactory, and thus provided a good basis for testing the hypothesized paths. The results show that recognition, empowerment, fair rewards, PJ, and POS had a positive significant influence on job engagement. In addition, job engagement had a negative significant influence on TI. Through this it was confirmed that an optimized organization(working) environment reduced employees' turnover intention by increasing their job engagement level. Therefore, it is suggested that F&B departments at super deluxe hotels design various internal marketing programs from the perspective of efficient human resource management. Implications and limitations, as well as future research directions are also discussed.

The area of security service has been maintaining the high growth curve annually by improving security consciousness from increase of the income and the progress of public services's level by the accomplishment in the info-communication field, recently the demand for unmanned security system is extended form commercial purposes into public offices and individual's houses. In addition to, the possible distance of offering services is scheduled to magnify. At the period when security company's influence has been becoming significant, the injustice transaction is the serious factor which obstructs the development of security companies. Therefore, it is urgent thing to devise counterplans to extirpate injustice transactions. There are the legalistic approaches of the breakthroughs against injustice transactions. One thing is settling the standard of the judgment and the other is renovating the provision of injustice transactions. Utilizing the principles of the fair competitions and importing self-obedience programs within the range of trade actions which is permitted by law, acted as the system approach. Moreover, there are such three things which can achieve mutual balances as establishing the range of the permitted action toward business corporations, applying spontaneously the fair competition principles and introducing the system of standard agreements. Gong further, this can establish order of security service areas and control them. Besides, it is possible for every organizations to make and operate the system appropriately by importing the self-observance system.

Guaranteed Frame Rate(GFR) service is intended to efficiently support TCP/IP traffic in ATM networks. The GFR service not only guarantees a minimum service rate at the frame level, but also supports a fair share of available bandwidth. The original GFR proposal outlined two switch implementation scheme : FIFO Queuing and perVC-Queuing. In general, it has been shown that FIFO Queuing is not sufficient to provide rate guarantees and perVC-Queuing with scheduling is needed. In perVC-Queuing implementation, scheduling algorithm plays key rule to provide rate guarantees and to improve fairness. We proposed a new scheduling algorithm for the GFR service. Proposed algorithm can provide minimum service rate guarantee and fair sharing to GFR VCs. Computer simulation results show that proposed scheduling scheme provide a much better performance in TCP Goodput and fairness than previous scheme.
