Various simulator systems for surgery training have been developed and recently become more widely utilized with technology advancement and change in medical education adopting actively simulation-based training. The authors have developed tissue-instrument interaction modeling and graphical simulation algorithms for an arthroscopic surgery training simulator system. In this paper, we propose algorithms for basic surgical techniques, such as cutting, shaving, drilling, grasping, suturing and knot tying for rotator cuff surgery. The proposed method constructs a virtual 3-dimensional model from actual patient data and implements a real-time deformation of the surgical object model through interaction between ten types of arthroscopic surgical tools and a surgical object model. The implementation is based on the Simulation Open Framework Architecture (SOFA, Inria Foundation, France) and custom algorithms were implemented as pulg-in codes. Qualitative review of the developed results by physicians showed both feasibility and limitations of the system for actual use in surgery training.

Communication has increasingly become important between peoples in the modern society. The change in the composition of a family brought by urbanization and industrialization caused structural changes in the society, and the lack of communication between people have incited various social conflicts rising from individualism and ego-centrism. Thus in this era, domestic environment is one of the most significant environment that enables one to transform into an appropriate member of the social community as well as develop appropriate traits of one. The living room, which served as an arena of communication for family members is now replaced with TV, a popular media, and has lost its original role in the house. The living room furnitures today are designed to facilitate people in viewing TV, not to enhance communication between family members. Thus in this research, I would like to propose a new concept of 'communication furniture' and various examples to suggest appropriate, desired role of living room furniture in households today. In addition, I hope this research contributes to forming a beneficial living room culture and a domestic environment as well as a heart-warming, human society.

In this study, real fire tests were performed on representative combustibles of residential facilities to analyze the fire behavior and combustion characteristics in a small residential space. The considered combustibles were a sofa, a combination of a desk and a chair, and a combination of a mattress and an electric mat. A compartment space fire test was performed using the room corner test equipment prescribed in the KS F ISO 9705 specification. Three real fire tests were conducted by placing the combustible material inside a small compartment with insulation and finishing materials and by igniting the combustible material. Results showed that the peak heat release rate and peak smoke production rate occurred in the combination of the mattress and electric mat. Furthermore, from the result of the fire rate analysis, it was estimated that the fire risk of the mattress and electric mat combination was the highest, followed by the sofa and thedesk and chair combination.

Purpose: In patients with altered mentality caused by drugs or unknown causes, ammonia is checked to facilitate differential diagnosis or diagnose hepatic coma. This helps early prevention and treatment of brain damage due to hyperammonemia. This study was conducted to evaluate clinical characteristics of intoxicated adult patients with hyperammonemia. Methods: We evaluated 95 patients with hyperammonemia among intoxicated patients above the age of 15 who visited our ED from January 2013 to December 2015. We analyzed the demographic characteristics and type of poisoning substance, reason for ingestion, toxicological characteristics such as elapsed time from ingestion to hospital visit, lab, clinical progression and complications. Data were evaluated using the student's t test or Mann-Whitney U test for continuous variables, and Chi-square test and Fisher's exact test for frequency analysis of categorical variables. Results: When compared to healthy individuals, patients with hyperammonemia showed statistical significance on their SOFA score (p=0.016) and poison severity score (p<0.001). Additionally, patients with hyperammonemia showed significantly different initial serum AST level (p=0.012) and maximum serum AST level during the hospital stay (p=0.026) when compared to healthy individuals. Moreover, individuals with sustained hyperammonemia compared to transient hyperammonemia showed clinically significant SOFA scores (p<0.001), poison severity scores (p=0.007), mortality rates in the ICU (p=0.021), as well as different duration of hospital stay (p=0.037), serum creatinine level (p=0.002), erythrocyte sedimentation rate (p=0.025), and serum myoglobin (p=0.015). Conclusion: Most poisoning-induced hyperammonemia cases were transient and recovered without special treatment. Therefore, hyperammonemia is almost non-specific among poisoning patients.

Background: The purpose of this study was to evaluate the risk factors for mechanical ventilation in the patients with scrub typhus admitted to intensive care unit (ICU) at a university hospital. Methods: We retrospectively selected and analyzed clinical data from the medical records of 70 patients (32 men, 38 women) admitted to the ICU with scrub typhus between 2004 and 2014. The patients had a mean${\pm}$standard deviation age of $71.2{\pm}11.1years$ and were evaluated in two groups: those who had been treated with mechanical ventilation (the MV group, n=19) and those who had not (the non-MV group, n=51). Mean ages of the MV group and the non-MV group were $71.2{\pm}8.3years$ and $71.2{\pm}11.1years$, respectively. Results: Significant differences between the two groups were observed with respect to acute respiratory failure (p=0.008), Acute Physiology and Chronic Health Evaluation (APACHE) II score (p=0.015), Sequential Organ Failure Assessment (SOFA) score (p=0.013), death (p=0.014), and ICU duration (p<0.01). Multivariate analysis indicated that the following factors were significantly associated with mechanical ventilation: acute respiratory failure (p=0.011), SOFA score (p=0.005), APACHE II score (p=0.011), platelet count (p=0.009), and lactate dehydrogenase (LDH) (p=0.011). Conclusion: Thus, five factors-acute respiratory failure, SOFA score, APACHE II score, platelet count, and LDH-can be the meaningful indicators for mechanical ventilation for the patients with scrub typhus admitted to ICU.
