Background: Advantages of paramedian approach over midline approach include less tissue trauma and less dependence on patient's ability to assume a fetal position. When midline approach fails in patients who are difficult to take a position with lumbar spine flexed, paramedian approach to interlaminar space may succeed. Methods: Success rates of spinal anesthesia were measured for 47 flexed patients by midline approach, 48 flexed patients by paramedian approach, 23 straightened patients receiving spinal anesthesia by midline approach, and 23 straightened patients by paramedian approach. Results: Success rates in flexed patients were 100% by midline approach and 100% by paramedian approach. Success rates for straightened patients were 13.0% by midline approach and 78.3% by paramedian approach. For straightened patients there were no correlations between success fate and age, weight, Ponderal Index but there were correlations between height and midline approach of spinal anesthesia. Conclusion: Pertaining to adult Koreans, success rates of spinal anesthesia for strainghtened patients were less than those for flexed patients. Success rate of paramedian approach of spinal anesthesia among strainghtened patients were better than those of midline approach.

Background: There is no established surgical procedure for the treatment of epiphrenic esophageal diverticulum. The aim of this study was to compare the clinical outcomes of esophageal diverticulectomy using abdominal and thoracic approaches. Methods: We retrospectively reviewed 30 patients who underwent esophageal diverticulectomy through the thoracic or abdominal approach for an epiphrenic diverticulum at a single center between 1996 and 2018. We compared clinical outcomes, including the postoperative length of stay, time from the operation to oral feeding, leakage rate, and reoperation rate between the 2 groups. Results: The median age was 56 years. Of the 30 patients, 18 (60%) underwent diverticulectomy via the thoracic approach and 12 (40%) underwent the abdominal approach. The median hospital stay was 10 days (range, 5-211 days) in the thoracic approach group and 9.5 days (range, 5-18 days) in the abdominal approach group. The median time from the operation until oral feeding was 6.5 days (range, 3-299 days) when the thoracic approach was used and 5 days (range, 1-11 days) when the abdominal approach was used. In the thoracic approach group, the leakage rate was 16.67% and the reoperation rate was 27.78%. However, there were no cases of leakage or reoperation in the abdominal approach group. Conclusion: The abdominal approach for esophageal diverticulectomy is a feasible and appropriate alternative to the thoracic approach.

This paper presents a hybrid approach to the sentiment analysis of online texts. The sentiment of a text refers to the feelings that the author of a text has towards a certain topic. Many existing approaches employ either a pattern-based approach or a machine learning based approach. The former shows relatively high precision in classifying the sentiments, but suffers from the data sparseness problem, i.e. the lack of patterns. The latter approach shows relatively lower precision, but 100% recall. The approach presented in the current work adopts the merits of both approaches. It combines the pattern-based approach with the machine learning based approach, so that the relatively high precision and high recall can be maintained. Our experiment shows that the hybrid approach improves the F-measure score for more than 50% in comparison with the pattern-based approach and for around 1% comparing with the machine learning based approach. The numerical improvement from the machine learning based approach might not seem to be quite encouraging, but the fact that in the current approach not only the sentiment or the polarity information of sentences but also the additional information such as target of sentiments can be classified makes the current approach promising.

To provide the wide and satisfactory surgical field is essential requirement for en-bloc resection of nasopharyngeal angiofibroma invading central skull base. The new design of the surgical approach to the skull base lesions was developed and described the details of this technique and its usefullness. We compared the usefullness of naso-maxillary approach to that of infratemporal fossa approach in cases of angiofibroma invading skull base. Our experience indicates that the naso-maxillary swing approach is better than lateral approach for the large nasopharyngeal angiofibroma. A new approach. naso-maxillary swing approach. is described.

Recently, the development of technology has been rapidly proceeding with information technology in various fields. Due to their abstract properties, proper evaluation of intangible assets is very difficult compared to evaluation of tangible assets. Intangible assets are knowledge, technology, and design etc. In general there are two approaches to evaluate the intangible assets such as qualitative and quantitative approach. The qualitative approach contains scoring approach, profile approach, checklist approach, and quantitative approach. Quantitative approach contains cost approach, market approach, income approach, and real-option approach. As an initial step for evaluation of safe work environments, this study compares and analyzes evaluation methods of intangible assets.

We aimed to see if approach-avoidance visual experience would have different effects in the valence rating of emojis. Previous literature has shown that approach-avoidance tendencies have influences people's emotional perceptions. Up until now, research on emojis have been heavily focused on static emojis, which gives room for exploration whether if movement added on to emoji would elicit different emotional responses. In the study, we examined the impact of approach-avoidance visual experience of emojis via mobile interface, categorized into 4 experimental conditions (positive approach, negative approach, positive avoid, and negative avoid), and conducted semi-structured interviews to identify users' reasonings towards their valence ratings on specific emojis with approach or avoid movements. We found that positive approach emojis were the highest valence rating and preferred by the participants, while there were no differences between negative emoji approach or avoidance. Based on these findings, we conclude that positive emojis could be intensified to be more positive with approach motion, yet for negative emojis, individual differences or contextual differences may arise in its emotional ratings.

Surgical approaches to the condylar fracture include intraoral, preauricular, submandibular, and retromandibular approaches. Each approach has its own advantages and disadvantages. When a patient needs esthetic results and an intraoral approach is not feasible, the transmasseteric antero-parotid facelift approach is considered. This approach permits direct exposure and allow the surgeon to fixate the fractured unit tangentially. Tangential fixation is critical to osteosynthesis. Disadvantages of the transmasseteric antero-parotid facelift approach include damage to the facial nerve and a longer operation time. However, after the initial learning curve, facial nerve damage can be avoided and operation time may decrease. We report three cases of subcondylar fractures that were treated with a transmasseteric antero-parotid facelift approach. Among these, two cases had trivial complications that were easily overcome. Instead of dissecting through the parotid gland parenchyma, the transmasseteric antero-parotid facelift approach uses transmasseteric dissection and reduces facial nerve damage more than the retromandibular transparotid approach. The esthetic result is superior to that of other approaches.

Purpose of this study is to find the research direction to solve the housing problems for the elderly which based on approaches and issues in related studies. Research method was interpretative analysis of the articles issued from 1976 to 2002. Each approach (rationalistic approach, ecological approach, micro-sociological approach, typological approach, environment-psychological approach, welfare approach) produced helpful information and had relative merits. But the researchers must regard housing for the elderly as a social problem in macroscopic view to solve the housing problems for older people with welfare approach. As a result, to solve the housing problems with welfare approach for the elderly who live in their own place with community care, studies about lifetime home, care and repair, and management of housing for the elderly might be needed. And research about existing services, transfer system of services, financial problems, man power to manage the system might be needed to spread out the services to the middle class elderly.

Objective : The purpose of this study is to evaluate the surgical outcomes of bifrontal interhemispheric[BIH] approach and compare them to those of the pterional approach for the treatment of craniopharyngioma. Methods : Seventeen patients had their first operation for the resection of craniopharyngiomas between 2000 and 2004 at our medical center. Eleven patients who had the pterional approach and 6 with the BIH approach were enrolled. The age range at the time of surgery was 5 to 80 years [mean age 35.6 years old]. The presenting symptoms were visual disturbance increased intracranial pressure in 5 patients. Results : The tumors were totally removed in 3 [27 %] and subtotally in 8 [73 %] patients with the pterional approach. Total tumor removal was achieved in 5 out of 6 [83%] patients by the BIH approach, except improved in 4 [36 %] patients treated with the pterional approach and in all patients treated by the BIH approach. Conclusion : The BIH approach for craniopharyngioma surgery may be an effective and safe approach for tumors that extend outside of the sellar-suprasellar region with acceptable outcomes.
