Polydopamine As Active Templates For Fabrication Of Conductive Of Copper Line Pattern, Raweewan Thongprachan Jan 2014

Polydopamine As Active Templates For Fabrication Of Conductive Of Copper Line Pattern, Raweewan Thongprachan

Chulalongkorn University Theses and Dissertations (Chula ETD)

In this research, copper conductive patterns were fabricated on polyethylene terephthalate (PET) substrate by combination of spray drying of polydopamine nanoparticles, and consequently electroless plating process. The polydopamine nanoparticle ink was synthesized by self-polymerization of dopamine hydrochloride at different initial pH 8, 8.5, 9 and 10. The patterns were deposited by site-selective Cu electroless plating process on top of the PDA pattern at the controlled temperature 30 C. The effects of plating time in electroless plating and storage time were studied. Moreover, the adhesion and aspect ratio were also investigated. The conductive lines fabricated were characterized by two-point probe measurement, …

Production Process Improvement For The Marinated Pork Factory, Patcharaporn Musuwan Jan 2014

Production Process Improvement For The Marinated Pork Factory, Patcharaporn Musuwan

Chulalongkorn University Theses and Dissertations (Chula ETD)

A marinated pork manufacturing company of Thailand has been wanting to expand its sales channels by moving its marinated pork products from solely lower market sales channel into Thailand’s hypermarket in order to attract more customer target groups. To do so, the company needed to adapt all Good Manufacturing Practices (GMP) standards in its factories and become GMP certified by Thailand’s Food and Drug Administration (FDA) to satisfy the requirement of most popular hyper markets in Thailand. The aim of this thesis is to implement solutions that would help this marinated pork company achieve GMP standards and improve its production …

Understand Management Of Public-Private Partnership In A Secondary Private Hospital Providing Services To Citizens Registered Under Different Insurance Schemes, Rani Sachadev Jan 2014

Understand Management Of Public-Private Partnership In A Secondary Private Hospital Providing Services To Citizens Registered Under Different Insurance Schemes, Rani Sachadev

Chulalongkorn University Theses and Dissertations (Chula ETD)

In light of the recent public-private partnership law reenacment in various industries, it seems that the healthcare's public insurances would largely benefit from increase participation of the private sector but since there has not been any published framework on management of public-private partnership in public health insurance, this study has been undertaken to shine a light on financial and medical care delivery in a secondary private hospital. This study was conducted in a secondary private hospital located in Bangkok providing UC, SSS and for-profit medical care to citizens. This is a study aimed to understand the management strategies regarding finance …

Effects Of Acemannan Deacetylation On Biological Activity Of Gingival Fibroblast, Jaroenporn Chokboribal Jan 2014

Effects Of Acemannan Deacetylation On Biological Activity Of Gingival Fibroblast, Jaroenporn Chokboribal

Chulalongkorn University Theses and Dissertations (Chula ETD)

Acemannan extracted from Aloe vera gel is unique in the presence of acetylated mannose residues and was reported to accelerate mice buccal wound healing. In order to assert structural and biological roles of mannose acetyl groups, high-molecular-mass DeAcAM of various DDAs were prepared by alkaline hydrolysis at 80°C for 5 min using varied concentrations of NaOH. All of the DeAcAMs are not cytotoxic to HGFs and their effects on cell proliferation and VEFG and type I collagen expressions were further investigated. In general, bioactivities of the DeAcAMs were lost to some extents upon the removal of the mannose acetyl groups …
