Background: The conventional transcervical resection for submandibular gland disease has some risks and an unsatisfactory cosmetic result. Recently, robot-assisted surgery has been developed as a plausible substitute for conventional surgery which provides an excellent cosmetic outcome. Case presentation: The authors performed robot-assisted sialadenectomy via modified facelift incision using the da Vinci Xi surgical system (Intuitive Surgical Inc., CA, USA) with two endowrist arms (monopolar curved scissors and Maryland bipolar forceps) successfully in a 44-year-old female patient who suffered from sialolith and severe atrophic submandibular gland. Conclusions: If similar studies are done in the future, this robot-assisted sialadenectomy may become established as an alternative to existing disadvantageous surgical methods.

Purpose: This study was performed to evaluate and compare health conservation and its related factors of elders in assisted living facilities or nursing homes. Method: Data for health conservation was collected from 316 elders in 10 institutions in Daegu city and Kyungpook province from February 1st to February 22nd, 2005. Data was collected by a structured questionnaire that included general characteristics, general health status, health conservation, functional health status (ADL, IADL) and depression (GDS-K) scales. The collected data was analyzed by the SPSS (version 11.5) program including descriptive statistics, t-test, -test, Pearson's correlation and stepwise method regression analysis. Result: The elders in assisted living facilities revealed lower scores in health conservation, ADL and IADL than the elders in nursing homes. Predictable variables influencing health conservation of the elders in assisted living facilities were depression and MAC (Mid-Arm Circumference) that is equal to .270, and the the elders in nursing home were depression, IADL, degree of sleep, and TSF (Triceps Skin Fold) that is equal to .409. Conclusion: The development of a health conservation program and long-term health care service system for elders in assisted living facilities are needed than for the elders in nursing homes.

In this study, after Library-Assisted Instruction is set out and executed, it is surveyed and verified the connection between Learning Attitude and Life competence. This study indicates that Learning Attitude and Life skills of Library-Assisted Instruction have close correlation and the extension of Life competence(Communication, Problem Solving. Self-Directed Learning) is under the influence of Learning Attitude. This study suggests that cooperative learning, Information Processing Model and constructivism learning theory have to be adopted as a means of increasing more educational effects and extensions of Library-Assisted Instruction.

In this report, the process characteristic(viscosity), mechanical properties, combustion characteristics, ground and flight test results of propellants used for a rocket-assisted projectile are described according to several aluminum contents. As the aluminum content increased, initial viscosity decreased, viscosity build-up accelerated, and combustion rate and pressure exponent decreased. In the ground fire test, the total impulse of the rocket-assisted projectiles containing 10 wt% of aluminum were 5% higher than that of the rocket-assisted projectiles containing 2 wt% and 18 wt% of aluminum. The motor efficiency compared to the theoretical performance was 85.6% with 18 wt% of aluminum, the lowest value among the propellant compositions.

Lobectomy is the standard treatment for early non-small cell lung cancer. Various surgical techniques for lobectomy have been developed, and minimally invasive thoracic surgery, such as video-assisted thoracic surgery or robot-assisted thoracic surgery, has been considered as an alternative to conventional open thoracotomy. The recently robotic lobectomy technique has developed since the first case series was published in 2002. Several studies have reported that robotic lobectomy has comparable oncologic and perioperative outcomes to those of video-assisted thoracic surgery lobectomy and open lobectomy. However, robotic lobectomy remains a challenge for surgeons because of the steep learning curve, reduced tactile sensation, difficulty in port placement, and challenges in cooperation between the surgeon and assistant. Many studies have reported on robotic lobectomy, but few have presented surgical techniques for robotic lobectomy. In this article, the surgical techniques and optimal performance of robotic lobectomy are described in detail for all 5 types of lobectomy for surgeons beginning with robotic lobectomy.

Robotic surgery facilitates surgical procedures by employing flexible arms with multiple degrees of freedom and providing high-quality 3-dimensional imaging. Robot-assisted nipple-sparing mastectomy with immediate reconstruction is currently performed to avoid breast scars. Four patients with invasive ductal carcinoma underwent robot-assisted nipple-sparing mastectomy and immediate robot-assisted expander insertion. Through a 6-cm incision along the anterior axillary line, sentinel lymph node biopsy and nipple-sparing mastectomy were performed by oncologic surgeons. The pectoralis major muscle was elevated, an acellular dermal matrix (ADM) sling was created with robotic assistance, and an expander was inserted into the subpectoral, sub-ADM pocket. No patients had major complications such as hematoma, seroma, infection, capsular contracture, or nipple-areolar necrosis. The mean operation time for expander insertion was 1 hour and 20 minutes, and it became shorter with more experience. The first patient completed 2-stage prosthetic reconstruction and was highly satisfied with the unnoticeable scar and symmetric reconstruction. We describe several cases of immediate robot-assisted prosthetic breast reconstruction. This procedure is a feasible surgical option for patients who want to conceal surgical scars.

Robot-assisted nipple-sparing mastectomy with immediate reconstruction is currently performed in an attempt to seek smaller and indistinct incisions. Robotic surgery system has been evolving under the concept of minimal invasive technique which is a recent trend in surgery. One of the latest version is the da Vinci SP Surgical System (Intuitive Surgical). In this report, we will share our experiences. Two patients underwent robot-assisted nipple-sparing mastectomy, each followed by immediate robot-assisted expander insertion and prepectoral direct-to-implant breast reconstruction, respectively. There was no open conversion or major postoperative complication. One patient experienced mild infection, which was resolved by intravenous antibiotic treatment. Simple docking process, multi-joint instruments, and thirdarm functionality are among the new surgical system's advantages. The present cases suggest that robot-assisted nipple-sparing mastectomy with immediate reconstruction using the da Vinci SP Surgical System is feasible and safe. The promising features and potential application of da Vinci SP in breast reconstruction need further study.

Laparoscopic endoscopic cooperative surgery (LECS) refers to the endoscopic dissection of the mucosal or submucosal layers with laparoscopic seromuscular resection. We recommend a treatment algorithm for the LECS procedure for gastric benign tumors according to the protruding type. In the exophytic type, endoscopic-assisted wedge resection can be performed. In the endophytic type, endoscopic-assisted wedge resection of the anterior wall is relatively easy to perform, and endoscopic-assisted transgastric resection, laparoscopic-assisted intragastric surgery, or single-incision intragastric resection in the posterior wall and esophagogastric junction (EG Jx) can be attempted. We propose an algorithm for the LECS procedure for early gastric cancer according to the tumor location. The endoscopic submucosal dissection (ESD) procedure can be adapted for all areas of the stomach, and single-incision ESD can be performed in the mid to high body and the EG Jx. In full-thickness gastric resection, laparoscopy-assisted endoscopic full-thickness resection can be adapted for the entire area of the stomach, but it cannot be applied to the pyloric and EG Jx. In conclusion, surgeons need to select the LECS procedure according to tumor type, tumor location, the surgeon's individual experience, and the situation of the institution while also considering the advantages and disadvantages of each procedure.

This study was attempted to systematically analysis the characteristics and effects of studies that applied animal assisted therapy to elementary students. Literature searches were conducted in 4 domestic academic databases(RISS, KISS, ScienceON, KMBASE). The characteristics of selected 26 studies were individually analyzed and described by publication year, research method, subject characteristics, intervention characteristics, and outcome variables, and the characteristics of the study were systematically summarized. The effect of the assisted therapy was divided into psychological-emotional effect, interpersonal effect, and other effect. Most of the psychological-emotional indicators and interpersonal relationship indicators were found to be effective, and inconsistent results were found for some indicators. It is expected that it can be used as a useful data when conducting assisted therapy studies targeting elementary school students in the future.

Closed reduction using acrylic splints with circummandibular fixation has been known to be useful techniques in pediatric mandibular fractures. However, this technique has some shortcomings, including needs for impression taking or additional laboratory process, which can increase the exposure time of general anesthesia or make an additional sedation visit. Recently, the advancement of computer-aided maxillofacial surgery offers to clinicians to expansion of its application. This case report represents a technique of computer-assisted virtual reconstruction and computer-aided designed splint fabrication in a 2-year-old boy with mandibular body fracture.
