Introduction: Three ways of simple calculations (segmental based on 18 segments method, segmental based on 19 segments method and subsegmental method) of predictive postoperative values of FEV1 and DLCO are in use during the preoperative survey for patients planned for lung resection as treatment of lung carcinoma as a part of risk assessment. Hypothesis: Segmental calculation method based on 19 segments is better than subsegmental method and segmental calculation method based on 18 segments in prediction of postoperative values of both FEV1 and DLCO one month after lung lobectomy. Materials and methods: Expected postoperative calculated values of FEV1 and DLCO (two segmental and one subsegmental method) of 52 patients undergone lobectomy are related to real postoperative values for same patients one month after surgery. Results: According to univariate analysis, real values of postoperative DLCO correlate most significantly with ppoDLCO calculated by segmental method (18 segments), but real values of postoperative FEV1 correlate most significantly with ppoFEV1 calculated by 19 overall segments segmental method. Data analysis as well showed that preoperative calculated PpoFEV1 and PpoDLCO underestimate real postoperative values of FEV1 and DLCO one month after lobectomy, but it is not statistically significant. Discussion: Same as contemporary guidelines suggest, ppoFEV1 calculation by 19 segments segmental method seems to be the best choice. PpoDLCO is maybe better to calculate by 18 segments segmental method.

The rate of stroke incidence is about 200 per 100,000 people throughout the world. This study aims to determine the Relation Suffer Stroke With Independence Level In Neurology Polyclinic TK II DR Ak Gani Palembang Year Hospital 2017. The research method used is descriptive quantitative with cross sectional design that is done by interviewing techniques with questionnaires on 42 respondents with Accidental sampling technique. This research was conducted in August 2017. Data analysis used is univariate data analysis and bivariate data analysis with one way anova test result. The results of univariate analysis showed that the duration of the respondents suffering from stroke was between 2.10 years to 3.38 years. Also found that most respondents were at the level of independence f; independent, except bathing, dressing, moving, and one other function with a total of 12 respondents. The results showed that there was a significant relationship between the long suffering stroke with the level of independence with the value of p value 0.025. For that the need for rehabilitation to patients and families of patients in order to help improve the independence of stroke patients in doing their daily activities.

Abstract BACKGROUND Cushing disease (CD) comprises a spectrum of clinical manifestations secondary to hypercortisolism due to ACTH-secreting pituitary adenoma. Transsphenoidal adenomectomy remains the standard treatment. Because of the significant rate of recurrence or persistence of CD, it is of interest to determine factors that may correlate with long-term outcomes following surgical intervention. OBJECTIVE The objective of our study is to determine the remission rate after surgery with special emphasis on factors affecting remission. METHODS Data of all patients undergoing surgery for CD from 2009 to 2017 was analyzed retrospectively. Transphenoidal resection was the preferred treatment with a recent trend in favor of endonasal endoscopic skull base approach. Post-operative cortisol level of < 2 μg/dL was taken as remission and value between 2 and 5 μg/dL as possible remission. RESULTS 104 patients operated primarily for CD were included for analysis. 47 patients underwent microscopic surgery, 55 endoscopic surgery and two were operated trans-cranially. Remission was achieved in 76.47% of patients. In univariate analysis, factors significantly associated with remission were (1) type of surgery (p=0.01); endoscopy (88.23% remission) better than microscopy (56.6% remission) (2) postoperative day-1 morning cortisol (p=0.004) and; (3) postoperative day-1 morning ACTH (p=0.015). In multivariate analysis, however only postoperative day-1 cortisol was found to be significant as predictor of remission (p=0.02). CONCLUSION Postoperative plasma cortisol level is a strong independent predictor of remission and value less than 10.7µgm/dl can be taken as cut off for predicting remission. Remission provided by endoscopy appears to be significantly better than microscopic approach.

With the development of science and technology, system management is gradually applied to tourism management. How to correctly assess the security risks of the tourism management system has become an important means to maintain passenger information. The security risk index of the travel management system is input into the PSO-BP network as a sample, and the corresponding risk value of the index is used as the network output. The results show that the error results, accuracy (96.53%), training time (216 s), number of iterations (275 times), and convergence speed are all better than traditional BP network. The relative error of PSO-BP network (0.32%) is better than that of BP network, with 300 iterations, and the error is close to 10–5. The average evaluation accuracy of S based on PSO-BP network is 99.72%, and the average time consumed is 2.512 s. It is superior to the evaluation model based on fuzzy set and entropy weight theory and the evaluation model based on gray correlation analysis and radial basis function neural network. In conclusion, the security risk assessment of the tourism management system based on PSO-BP network can effectively assess the security risk of the tourism management system.

AbstrakMatematika merupakan ilmu abstrak, untuk mempelajarinya diperlukan kemampuan yang memadai. Salah satunya memiliki kemampuan untuk mengkomunikasikannya dalam bentuk ide, simbol, maupun bahasa matematika. Selain itu, komunikasi merupakan bagian yang sangat penting dalam matematika. Untuk mengembangkan kemampuan komunikasi matematis diterapkan pembelajaran Group Investigation. Pembelajaran ini menekankan pada keaktifan mahasiswa ketika pembelajaran. Populasi dalam penelitian ini yaitu mahasiswa di salah satu perguruan tinggi swasta di Garut, dengan sampel dua kelas mahasiswa tingkat II yaitu kelas B sebagai kelas eksperimen dan kelas C sebagai kelas kontrol. Instrumen yang digunakan dalam penelitian ini berupa tes kemampuan komunikasi matematis, yang digunakan pada pretest dan posttest. Analisis data pada hasil pretest diawali dengan uji normalitas kemudian uji Mann Whitney. Sedangkan analisis data pada hasil posttest diawali dengan uji normalitas, uji homogenitas, kemudian uji t. Secara garis besar, hasil penelitian ini menunjukkan bahwa kemampuan komunikasi matematis mahasiswa yang mendapatkan pembelajaran Group Investigation lebih baik daripada mahasiswa yang mendapatkan pembelajaran konvensional. AbstractMathematics is an abstract science, to learn it required adequate capability. One of which has the ability to communicate it in the form of ideas, symbols, and math language. Besides, communication is a very important part in mathematics. To develop mathematical communication abilities applied Group Investigations learning. This lesson emphasizes student activeness. Population in this research were students in one private college in Garut, with sample of two classes of students of grade two that is class B as experiment class and C as control class. The instrument used in this research is a test of mathematical communication ability, used in pretest and posttest. Data analysis on pretest result begins with normality test then Mann Whitney test. While data analysis on posttest result begins with normality test, homogeneity test, and t test. In general, the results of this study indicate that the mathematical communication skills of students who get Group Investigation learning better than students who get conventional learning.
