Korean Home Learning Environment and Parent Characteristics Influencing Children\u27s Expressive and Receptive Language Abilities
This study analyzed data derived from āThe Panel Study on Korean Childrenā implemented by the Korea Institute of Child Care & Education (KICCE). Two scales, EC-HOME and REVT were used to investigate specific types of home environments and parent characteristics beneficial in the facilitation of childrenās receptive and expressive language development. The Step-wise Multiple Regression Analysis identified four variables (Responsively, Physical Environment, Father Education, and Mother Habitation) that made a significant contribution to childrenās receptive language development, and six different variables (Mother Education, Academic Stimulation, and Physical Environment, Acceptance, Motherās Current Job Status, and Communicative Stimulation) for expressive language development. This study found that home learning environment is a more significant factor for children\u27s receptive and expressive language development than parent demographic characteristics with the exception of the education level of parents, current job status of the mother, and habitation status of the mother
Peekaboo: A Hub-Based Approach to Enable Transparency in Data Processing within Smart Homes (Extended Technical Report)
We present Peekaboo, a new privacy-sensitive architecture for smart homes
that leverages an in-home hub to pre-process and minimize outgoing data in a
structured and enforceable manner before sending it to external cloud servers.
Peekaboo's key innovations are (1) abstracting common data pre-processing
functionality into a small and fixed set of chainable operators, and (2)
requiring that developers explicitly declare desired data collection behaviors
(e.g., data granularity, destinations, conditions) in an application manifest,
which also specifies how the operators are chained together. Given a manifest,
Peekaboo assembles and executes a pre-processing pipeline using operators
pre-loaded on the hub. In doing so, developers can collect smart home data on a
need-to-know basis; third-party auditors can verify data collection behaviors;
and the hub itself can offer a number of centralized privacy features to users
across apps and devices, without additional effort from app developers. We
present the design and implementation of Peekaboo, along with an evaluation of
its coverage of smart home scenarios, system performance, data minimization,
and example built-in privacy features.Comment: 18 page

Tissue Adequacy and Safety of Percutaneous Transthoracic Needle Biopsy for Molecular Analysis in Non-Small Cell Lung Cancer: A Systematic Review and Meta-analysis
OBJECTIVE: We conducted a systematic review and meta-analysis of the tissue adequacy and complication rates of percutaneous transthoracic needle biopsy (PTNB) for molecular analysis in patients with non-small cell lung cancer (NSCLC).
MATERIALS AND METHODS: We performed a literature search of the OVID-MEDLINE and Embase databases to identify original studies on the tissue adequacy and complication rates of PTNB for molecular analysis in patients with NSCLC published between January 2005 and January 2020. Inverse variance and random-effects models were used to evaluate and acquire meta-analytic estimates of the outcomes. To explore heterogeneity across the studies, univariable and multivariable meta-regression analyses were performed.
RESULTS: A total of 21 studies with 2232 biopsies (initial biopsy, 8 studies; rebiopsy after therapy, 13 studies) were included. The pooled rates of tissue adequacy and complications were 89.3% (95% confidence interval [CI]: 85.6%-92.6%; I(2) = 0.81) and 17.3% (95% CI: 12.1%-23.1%; I(2) = 0.89), respectively. These rates were 93.5% and 22.2% for the initial biopsies and 86.2% and 16.8% for the rebiopsies, respectively. Severe complications, including pneumothorax requiring chest tube placement and massive hemoptysis, occurred in 0.7% of the cases (95% CI: 0%-2.2%; I(2) = 0.67). Multivariable meta-regression analysis showed that the tissue adequacy rate was not significantly lower in studies on rebiopsies (p = 0.058). The complication rate was significantly higher in studies that preferentially included older adults (p = 0.001).
CONCLUSION: PTNB demonstrated an average tissue adequacy rate of 89.3% for molecular analysis in patients with NSCLC, with a complication rate of 17.3%. PTNB is a generally safe and effective diagnostic procedure for obtaining tissue samples for molecular analysis in NSCLC. Rebiopsy may be performed actively with an acceptable risk of complications if clinically required
