PURPOSE: This study was done to identify factors that influence sexual permissiveness. A comprehensive analysis of individual, family, and social factors related to sexual permissiveness in adolescents was done. METHOD: A descriptive research design was used to explore causal relationships in sexual permissiveness between high school students. RESULT: The findings of this study are as follows. 1) For individual factors, self-respect, seeking social deviation and seeking internal experience were confirmed as factors influencing sexual permissiveness. 2) For the family factors, the mother-adolescent communication aspect was confirmed as a factor. 3) For the social environment factors, adaptability to school life was confirmed as a factor. CONCLUSION: On a theoretical basis, this study identifies factors influencing sexual permissiveness in adolescents, and thus contributes to the definition of a desirable sexual culture for young people. Therefore, it is suggested that programs be developed that control the corroborated factors and that further studies be conducted to validate the factors.

Global climate change is expected to pose increasing challenges for cities in the following decades, placing greater stress and impacts on multiple social and biophysical systems, including population health, coastal development, urban infrastructure, energy demand, and water supplies. Simultaneously, a strong global trend towards urbanisation of poverty exists, with increased challenges for urban populations and local governance to protect and sustain the wellbeing of growing cities. In the context of these 2 overarching trends, interdisciplinary research at the city scale is prioritised for understanding the social impacts of climate change and variability and for the evaluation of strategies in the built environment that might serve as adaptive responses to climate change. This article discusses 2 recent initiatives of The Earth Institute at Columbia University (EI) as examples of research that integrates the methods and objectives of several disciplines, including environmental health science and urban planning, to understand the potential public health impacts of global climate change and mitigative measures for the more localised effects of the urban heat island in the New York City metropolitan region. These efforts embody 2 distinct research approaches. The New York Climate & Health Project created a new integrated modeling system to assess the public health impacts of climate and land use change in the metropolitan region. The Cool City Project aims for more applied policy-oriented research that incorporates the local knowledge of community residents to understand the costs and benefits of interventions in the built environment that might serve to mitigate the harmful impacts of climate change and variability, and protect urban populations from health stressors associated with summertime heat. Both types of research are potentially useful for understanding the impacts of environmental change at the urban scale, the policies needed to address these challenges, and to train scholars capable of collaborative approaches across the social and biophysical sciences.

OBJECTIVETo study the main factors affecting sound-insulation effects of control rooms in workshops with noise, so as to improve the protection.

METHODSThe sound-insulation effects of 467 control rooms were determined, and different building materials, structures of door and window, airtight states etc. were analyzed.

RESULTSThe affecting factors contributed to the sound-insulation effects (Eta(2)) were in the order: airtight states (0.168), building materials (0.080), structures of window and door (0.030, 0.029), sound pressure levels and frequency spectrum's characteristics (0.008, 0.006). Under airtight state, the sound-insulation effects of different building materials of the rooms were as follows: double bricks [(19.6 +/- 3.5) dB(A)]; single brick [(15.4 +/- 3.4) dB(A)]; plank [(13.1 +/- 1.6) dB(A)] or aluminum alloy plate with glass [(13.4 +/- 2.5) dB(A)] (P < 0.01). Of 4 group rooms, with the same structure of doors but double or single bricks of windows. 3 groups with dormant window had higher sound-insulation effects [(15.9 +/- 2.8), (18.7 +/- 3.6), (19.3 +/- 2.5) dB(A)] than those with casement window [(14.1 +/- 2.4), (14.9 +/- 2.3), (16.5 +/- 2.4) dB(A)] (P < 0.01 or P < 0.05); 2 groups with dehydrated window [(18.7 +/- 3.3), (22.6 +/- 3.8) dB(A)] higher than those with dormant window [(15.9 +/- 2.8), (19.9 +/- 3.0) dB(A)] (P < 0.05). Of 6 group rooms, with the same structure of windows but double or single bricks of doors, only in 1 group with double-layer door had higher sound-insulation effect [(18.7 +/- 3.6) dB(A)] than that with single-layer door [(15.9 +/- 2.8) dB(A)] (P < 0.01).

CONCLUSIONThe control room should be designed rationally, kept airtight, according to the sound pressure levels and the condition of the workshop.

Oxygen enrichment of room air is an effective way to resist hypoxia at high altitude, but it may introduce a potential fire hazard. In common, the burning rate of light and thin homogeneous solid in oxygen enriched atmosphere was used to assess the fire hazard. For the purpose of measuring the burning rate of light and thin homogeneous solid in oxygen enriched atmosphere, we used the methods of laser contact ignition and direct calculation of burning rate, and invented a device that includes mixing gas system, ignition equipment, system of measuring the burning rate and self-made specimen frame. By using the homemade device, we studied the burning rate of filter paper under low pressure and in oxygen-enriched atmosphere and in that of the oxygen concentration of reached stationary burning rate. The results showed that this device was simple, and could obtain the burning rate of light and thin homogeneous solid quantitatively.

The teaching laboratory is the central place to teach lab courses to undergraduate students. It is thus critical to evaluate how lab skills of students will be affected by the management of this lab. This study attempts to introduce the 6S concept, referring to "Seiri", "Seiton", "Seiso", "Seiketsu", "Shisuke", and "Safety", to the management of teaching laboratory, in particular, to the management of environments, safety, item deposition, reagents and consumables in the laboratory. We find that applying the "6S" management maintains a tidy lab environment, facilitates teaching the lab skills, and improves the quality of teaching, which together achieves the goal of education with the atmosphere. This study can provide a guideline for establishing and managing teaching laboratories in universities.

OBJECTIVETo explore the feasibility of the animal experimental cabin to copy the animal models with ATM/LP and low oxygen and high carbon dioxide environment.

METHODS60 SPF-class male SD rats were divided into two groups, 20 for normobaric hypoxia control experiments and the other 40 for hypobaric hypoxia control experiments. For each group, examine the pulmonary arterial pressure and carotid arterial pressure indicators of rats by using the multi-detector measurement of physiological, and observe the pulmonary vascular changes in the structure.

RESULTSThe ATM/LP and low oxygen and high carbon dioxide environment can promote the formation of pulmonary hypertension and accelerate changes in pulmonary vascular remodeling, promoting right ventricular hypertrophy.

CONCLUSIONClinical applications showed that the animal experimental cabin was observing and controlling accurately, safe, reliable, and the results was reproducible. It can successfully copy the regular low-pressure hypoxia and hypercapnia environment pulmonary hypertension model, in order to study the physiological mechanism of a variety of circulation and respiratory diseases caused by oxygen-poor and provide an experimental technology platform.

PURPOSE: The study aimed to compare the physical activity of hematopoietic stem cell transplantation (HSCT) patients with healthy people (HP). METHODS: The research design of this study was cross sectional and, descriptive study. It was conducted from January 26th to May 22nd, 2013. We matched HSCT patients to HP based on age and gender, and measured physical activity using a pedometer. Patient's clinical information were gathered by the medical record reviews. RESULTS: The number of steps was significantly less in HSCT patients (HSCT: 214 (7~3,373) vs HP: 7,921 (3,180~17,539), p<.001). Physical activity time was significantly less in HSCT patients (HSCT: 840 (680~1,320)min vs HP: 990 (540~1,090)min, p<.001). Step count showed a significant relationship with platelet count (r=.40, p=.004). CONCLUSION: HSCT patients perform very low intensity of physical activities. The study shows the necessity to apply programs to promote physical activities in isolation rooms for patients undergoing HSCT.
