Objectives: Intraoperative tumor manipulation and dissemination may possibly compromise survival of women with early-stage cervical cancer who undergo minimally-invasive radical hysterectomy (RH). The objective of the study was to examine survival related to minimallyinvasive RH with a “no-look no-touch” technique for clinical stage IB1 cervical cancer. Methods: This retrospective study compared patients who underwent total laparoscopic radical hysterectomy (TLRH) with no-look no-touch technique (n=80) to those who underwent an abdominal radical hysterectomy (ARH; n=83) for stage IB1 (≤4 cm) cervical cancer. TLRH with no-look no-touch technique incorporates 4 specific measures to prevent tumor spillage: 1) creation of a vaginal cuff, 2) avoidance of a uterine manipulator, 3) minimal handling of the uterine cervix, and 4) bagging of the specimen. Results: Surgical outcomes of TLRH were significantly superior to ARH for operative time (294 vs. 376 minutes), estimated blood loss (185 vs. 500 mL), and length of hospital stay (14 vs. 18 days) (all, p<0.001). Oncologic outcomes were similar between the 2 groups, including disease-free survival (DFS) (p=0.591) and overall survival (p=0.188). When stratified by tumor size (<2 vs. ≥2 cm), DFS was similar between the 2 groups (p=0.897 and p=0.602, respectively). The loco-regional recurrence rate following TLRH was similar to the rate after ARH (6.3% vs. 9.6%, p=0.566). Multiple-pelvic recurrence was observed in only 1 patient in the TLRH group. Conclusion: Our study suggests that the no-look no-touch technique may be a useful surgical procedure to reduce recurrence risk via preventing intraoperative tumor spillage during TLRH for early-stage cervical cancer.

Purpose Most studies have investigated the differences in postgastrectomy quality of life (QOL) based on the surgical procedure or reconstruction method adopted; only a few studies have compared QOL based on tumor location. This large-scale study aims to investigate the differences in QOL between patients with esophagogastric junction cancer (EGJC) and those with upper third gastric cancer (UGC) undergoing the same gastrectomy procedure to evaluate the impact of tumor location on postoperative QOL. Methods The Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) questionnaire was distributed in 70 institutions to 2,364 patients who underwent gastrectomy for EGJC or UGC. A total of 1,909 patients were eligible for the study, and 1,744 patients who underwent total gastrectomy (TG) or proximal gastrectomy (PG) were selected for the final analysis. These patients were divided into EGJC and UGC groups; thereafter, the PGSAS-45 main outcome measures (MOMs) were compared between the two groups for each type of gastrectomy. Results Among the post-TG patients, only one MOM was significantly better in the UGC group than in the EGJC group. Conversely, among the post-PG patients, postoperative QOL was significantly better in 6 out of 19 MOMs in the UGC group than in the EGJC group. Conclusions Tumor location had a minimal effect on the postoperative QOL of post-TG patients, whereas among post-PG patients, there were definite differences in postoperative QOL between the two groups. It seems reasonable to conservatively estimate the benefits of PG in patients with EGJC compared to those in patients with UGC.

Psychological dependence in Japanese animation films: A case of Rin Taro

Yokota, Masao,Koide, Masashi,Nomura, Koji Korean Society of Cartoon and Animation Studies 2004 만화애니메이션연구 Vol.- No.8

There are many opportunistic events that accidentally happen in Rin Taro's animations. However, audiences usually enjoy them in which dramatic catastrophic scenes inflict destruction on a city. Every acquaintance that a hero meets helps him to complete his wish in <Galaxy Express 999>. Rin's animations describe the hero as a person that every acquaintance is eager to help. This means that the fulfillment of hero's wish depends on sympathy of the other persons toward the hero. Thus, the hero is psychologically dependent on the others. However, Rin Taro gradually became to describe destructive aspects of psychological dependence. A female character in 'X' has a symbiotic relationship with a computer that has a human-like jealousy. At last, it kills her from its jealousy. Rin Taro had shifted from helpful psychological dependence to destructive one in his animations. Therefore, Rin Taro described Japanese mental state as psychological dependence in his animations in accordance with the present state in Japan.

Application of Neural Network Analysis to Automatic Detection of Road Surface Conditions Utilizing Tire Noise from Vehicles

Wuttiwat Kongrattanaprasert,Hideyuki Nomura,Tomoo Kamakura,Koji Ueda 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

This paper proposes a new method for automatically detecting the states of the road surface from tire noises of vehicles. The methods are based on a Fast Fourier Transform analysis, an artificial neural network, and the mathematical theory of evidence. The proposed classification is carried out in sets of multiple neural networks using the learning vector quantization networks. The outcomes of the networks are then integrated using the voting decision making scheme. It seems then feasible to detect passively and readily the states of the surface: i.e., as a rule of thumb,dry, wet, snowy and slushy state, automatically. The classification results in the validation set were greater than 80% in accuracy.

Transvaginal cervical tumor-concealing no-look no-touch technique in minimally invasive radical hysterectomy for early-stage cervical cancer: a novel operation technique

The Laparoscopic Approach to Cervical Cancer (LACC) trial demonstrated that minimally invasive radical hysterectomy was inferior to the open approach [1]; this unexpected result could be attributed to the spillage of cancer cells [2]. Following the LACC trial, laparoscopic radical hysterectomy without an intrauterine manipulator upon completion of a vaginal cuff closure became the new standard treatment method [3]. However, the lack of intrauterine manipulator results in poor visualization and inadequate paracervical tissue resection. This study describes the no-look no-touch technique to address this difficulty. The core procedures in our no-look, no-touch laparoscopic radical hysterectomy are: (Step 1) Creation and closure of a vaginal cuff; (Step 2) Manipulation of the uterus without an intra-uterine manipulator; and (Step 3) Exposure of the paracervical tissues by the suspension technique. The patient eligibility for our procedure is as follows: 1) previously untreated cervical cancer (those who underwent diagnostic conization could be included); 2) clinical stage IA2, IB1, IB2, and IIA1 based on the 2018 International Federation of Gynecology and Obstetrics staging system; 3) histologically confirmed cervical cancer, including squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma. The important indication for this procedure is in cases where the tumor is less than 4 cm in diameter. We previously reported that our no-look no-touch technique enables smooth performance of laparoscopic radical hysterectomy without worsening oncologic outcomes [4]. According to a recent systematic review and meta-analysis [5], minimally invasive radical hysterectomy with vaginal cuff closure is a safe treatment option; however, it involves a steep learning curve, which has impeded its increased application. This video will hopefully make minimally invasive radical hysterectomy with protective maneuvers against cancer cell spillage more accessible. Based on our experiences, we propose that our transvaginal cervical tumor-concealing no-look no-touch technique will mitigate the risk of surgical spill of tumor cells during minimally invasive radical hysterectomy. The informed consent for use of this video was taken from the patient.
