Purpose: The purpose of this research is to study the role of life satisfaction, quality consciousness, and religiosity, which are integrated with the TRA Model to explain the switching intention of Muslim consumers to use Halal Cosmetics and Personal Care (HCPC). The second purpose is to investigate the relationship between variables used in this study to provide recommendations to HCPC producers about Muslim consumer behavior in the market. Research design, data, and methodology: The target population in this study is Muslims who live in Greater Jakarta. Data collection is carried out by the self-administered survey method based on the Purposive sampling technique, and the questionnaire is distributed online. The statistical analysis to test the research hypotheses is the Partial Least Squares - Structural Equation Model (PLS-SEM). Results: Life satisfaction, product quality consciousness, and religious commitment have a significant effect on attitude to switching but do not significantly influence the intention of switching to use HCPC. Conclusions: Life satisfaction, quality consciousness, and religiosity that represent individual factors indirectly affect the intention to switch to use HCPC. Thus, religious commitment influences attitude to switching both directly and indirectly.

The purpose of this study was to determine cosmetic preferences and purchasing behavior of two segmented groups(career women vs. college females). We employed questionnaires and collected data from 443 people. Only 400 reliable questionnaires were used for a statistical analysis with SPSS program on the frequency, Chi-square test, and t-test. The results of this study were as follows: 1. The amount of makeup, and the reason for makeup were statistically associated with the segmented groups which are career women and college females. Also we realized that there was a significant difference in 'sophisticated' and 'sexy' makeup images. Both images were more highly sought in career women. 2. The preference of lip colors & textures, types of eye liner, and types of foundation were associated with the segmented career/college female groups. Both groups favored more glossy lipstick. Career women preferred liquid eye liner and foundation, while college females like to use no foundation. 3. Both career women and college females acquired information about cosmetics from the friend's advice rather than TV or magazine. In purchasing, career women considered the most quality, while college females considered suitable cosmetics for their natural skin types.

Septoplasty/septorhinoplasty is a common ear, nose and throat procedure offered for those patients with deviated septum who are suffering from nasal obstruction and functional or cosmetic problems. Although it is a basic and simple procedure, it could lead to catastrophic complications including major skull base injuries which result in cerebrospinal fluid (CSF) leaks. We describe two different cases of traumatic CSF leaks following septoplasty/septorhinoplasty at two different sites. The first patient suffered a CSF leak following septoplasty and presented to Alexandria University Hospital. The leak was still active at presentation and identified as coming from a defect in the roof of the sphenoid sinus and was repaired surgically. The second patient presented 4 days after her cosmetic septorhinoplasty with a CSF leak and significant pneumocephalus. She was managed conservatively. Understanding the anatomical variations of the paranasal sinuses and implementing proper surgical techniques are crucial in preventing intracranial complications when performing either septoplasty or septorhinoplasty. A good quality computed tomography of the nose and paranasal sinuses is a valuable investigation to avoid major complications especially CSF leaks following either procedure.

The implementation of national cancer screening has increased the detection rates of early gastric cancer (EGC) in Korea. Since the successful introduction of laparoscopic gastrectomy for gastric cancer in the early 1990s, this technique has demonstrated improved short-term outcomes without compromising long-term oncologic results. It is associated with reduced pain, shorter hospitalization, reduced morbidity rates, better cosmetic outcomes, and equivalent mortality rates as those for open surgery. Laparoscopic gastrectomy improves patients' quality of life (QOL) and provides favorable prognosis. Single-incision laparoscopic gastrectomy (SILG) is one extremely minimally invasive method, theoretically offering improved cosmetic results, less postoperative pain, and earlier recovery after surgery than conventional multiport laparoscopic gastrectomy. In this context, SILG is thought to be an optimal method to promote and maximize patients' QOL in the acute postoperative phase. However, the technical difficulties of this procedure have limited its use. Since the first report describing single-incision distal gastrectomy in 2011, only 16 studies to date have evaluated SILG. Most of these studies have focused on the technical feasibility and safety of SILG because its long-term outcomes have not been reported. This article reviews the advantages and limitations of SILG.

This paper presented characterization of spray velocity and angle of spray nozzle systems for cosmetic products. Diameter and length of nozzle orifice were chosen as shape factors of the spray system. Spray orifice of the spray pattern is a factor influencing the quality of the product. Fluid analysis was conducted by using "Fluent" to obtain spray angle and velocity. RSM (Response Surface Method) was used to approximate the relationship between these 2 factors and spray characteristics. To evaluate the proposed method, experimental work with existing was conducted and good agreement between simulation and experimental results.

This study attempted to establish a High Performance Liquid Chromatography (HPLC) analysis method for the determination of (-)-epicatechin gallate as a part of the quality control for the development of functional cosmetic materials from Penthorum chinense Pursh extracts. HPLC was performed on a Unison US-C18 column ($4.6{\times}250mm$, $5{\mu}m$) with a gradient elution of 0.05% (v/v) trifluoroacetic acid (TFA) and methyl alcohol at a flow rate of 1.0 mL/min at $30^{\circ}C$. The analyte was detected at 280 nm. The HPLC method was performed in accordance with the International Conference on Harmonization (ICH) guideline (version 4, 2005) of analytical procedures with respect to specificity, precision, accuracy, and linearity. The limits of detection and quantitation were 0.11 and 0.33 mg/mL, respectively. Calibration curves showed good linearity (r2 > 0.9999), and the precision of analysis was satisfied (less than 0.6%). Recoveries of quantified compounds ranged from 99.51 to 101.92%. This result indicates that the established HPLC method is very useful for the determination of marker compound in P. chinense Pursh extracts.
