The non-coding DNA in eukaryotic genomes encodes a language which programs chromatin accessibility, transcription factor binding, and various other activities. The objective of this short report was to determine the impact of primary DNA sequence on the epigenomic landscape across 200-base pair genomic units by integrating nine publicly available ChromHMM Browser Extensible Data files of the Encyclopedia of DNA Elements (ENCODE) project. The nucleotide frequency profiles of nine chromatin annotations with the units of 200 bp were analyzed and integrative Markov chains were built to detect the Markov properties of the DNA sequences in some of the active chromatin states of different ChromHMM regions. Our aim was to identify the possible relationship between DNA sequences and the newly built chromatin states based on the integrated ChromHMM datasets of different cells and tissue types.

We have reported to make nanostructured cobalt oxide electrode that have large capacitance over than 400F/g (specific capacitance) and good cycleability. But, It had serious demerits of low voltage range under 0.5V and low power density. Therefore, we need to increase voltage range of cobalt oxide electrode. we report here on the electrochemical properties of sol-gel-derived nanoparticulate cobalt xerogel in 1M KOH solution and aqueous polymeric gel electrolyte. In solution electrolyte, cobalt oxide electrode had over than 250F/g capacitance consisted of EDLC and pseudocapacitance. In gel electrolyte, cobalt oxide electrode had around 100F/g capacitance. This capacitance was only surface EDLC. In solution electrolyte, potassium ion as working ion reacted with both of layers easily. However, In gel electrolyte, reacted with only surface-active layer. Its very hard to reach resistive layer. So, e have studied on pretretmetn of electrode to contain working ions easily. We'll report more details.

A 3rd degree burn on the heel including the Achilles tendon is vulnerable and requires active treatment to improve the functional outcomes. Previously, there have been a few treatments on severe burns, such as amputation, debridement or simple skin graft. The cooperative technique of an anterior lateral thigh flap with Achilles tendon reconstruction can be an innovative procedure that preserves the major arteries. The authors review a case and report the clinical outcome.

Oral lichen planus (OLP) is a chronic oral mucosal disease affecting the buccal cheek, tongue, palate, lip, and gingival mucosa. Lesions in the gingiva make it difficult to control dental plaque due to pain. As a result, the disease is often accompanied by gingivitis or periodontitis. If OLP and dental plaque are not properly managed, the patient's periodontal condition will worsen. Thus, clinicians treating OLP should emphasize periodic visits and dental plaque control. Here, we report the management of a patient who struggled with OLP for 20 years and discuss the importance of periodic regular observations and active periodontal management.

This study was to investigate differences in peer attachment, emotion regulation style and depression perceived by adolescents according to age and gender of adolescents. Also, aim that identifies variables which have influences on adolescents' depression. The subjects were 2279 middle and high school students(male 1150, female 1129) who live in Seoul and Kyonggi. All respondents answered by self-report questionnaire. The scales of emotion regulation style consist of three parts: support-seeking, avoidance/distraction, and active problem-solving. Data were analyzed by two-way ANOVA, t-tset and stepwise multiple regression. The major findings were as follows. First, older male and female adolescents perceived less peer attachment than younger adolescents. Specially female adolescents showed more differences between older adolescents and younger adolescents. Second, male adolescents showed more avoidance/distraction style and active problem-solving style but less support-seeking style than female adolescents. Third, older adolescents perceived more depression than younger adolescents. Fourth, peer attachment, age, avoidance/distraction style, active problem-solving style, support-seeking style and gender had a significant effect on adolescents' depression. In other words, adolescents who had more avoidance/distraction style and support-seeking style, who had less peer attachment and active problem-solving style, who had more avoidance/distraction style and support-seeking style, who had less peer attachment and active problem-solving style, who was older adolescents than younger adolescents, and who was female adolescents than male adolescents perceived more depression. The study results suggest that the degree of peer attachment was the most powerful predictor of adolescents' depression.

The rapid deployment of millions of mobile sensors and smart devices has resulted in high demand for opportunistic encounter-based networking. For the cooperative video surveillance of dashboard cameras in nearby vehicles, a fast and energy-efficient asynchronous neighbor discovery protocol is indispensable because a dashboard camera is an energy-hungry device after the vehicle's engine has turned off. In the existing asynchronous neighbor discovery protocols, all nodes always try to discover all neighbors. However, a dashboard camera needs to discover nearby dashboard cameras when an event is detected. In this paper, we propose a fast and energy-efficient asynchronous neighbor discovery protocol, which enables nodes : 1) to have different roles in neighbor discovery, 2) to discover neighbors within a search range, and 3) to report promptly the exact discovery result. The proposed protocol has two modes: periodic wake-up mode and active discovery mode. A node begins with the periodic wake-up mode to be discovered by other nodes, switches to the active discovery mode on receiving a neighbor discovery request, and returns to the periodic wake-up mode when the active discovery mode finishes. In the periodic wake-up mode, a node wakes up at multiples of number ${\alpha}$, where ${\alpha}$ is determined by the node's remaining battery power. In the active discovery mode, a node wakes up for consecutive ${\gamma}$ slots. Then, the node operating in the active discovery mode can discover all neighbors waking up at multiples of ${\beta}$ for ${\beta}{\leq}{\gamma}$ within ${\gamma}$ time slots. Since the proposed protocol assigns one half of the duty cycle to each mode, it consumes equal to or less energy than the existing protocols. A performance comparison shows that the proposed protocol outperforms the existing protocols in terms of discovery latency and energy consumption, where the frequency of neighbor discovery requests by car accidents is not constantly high.

In order to operate the power system satisfactory for both system operators and customers, it is important to limit the harmonic currents to the allowable levels which injected into the system from the distorting installations. In this regard, the principles for the allocation of emission limits on individual customer were introduced in the technical report of IEC61000-3-6. According to these general principles, the emission limits are dependent on the agreed power of the customer, the power of the harmonic-generating equipment, and the system characteristics. The considerations in this report are very comprehensive and the process introduced is practical enough to implement as it is. However, there is a fact not appropriately dealing in the report that could be a very tickle but has a huge impact on determining the emission limit. This is the effect of non-harmonic load currents. More precisely, these are from the equipments which do not emit any harmonic or may emit harmonics but this specific order under the consideration by themselves if the source power is sinusoidal. The load currents originated from these equipments have an effect of active filter against the specific order of harmonic therefore, these should be dealt as a significant factoron the process of determining the emission limits for individual customer.
